ABSTRACT
Objective:To study the judgment strategies of stroke patients facing different visual stimulus and the main factors affecting the mental rotation test results. Methods:From May to October, 2018, 15 stroke patients and 15 age-sex-education-matched healthy controls accepted standard software-based mental rotation tests with four kinds of visual stimulus: hand back, hand palm, Chinese characters and alphabets. Reaction time and response accuracy were recorded. All the subjects were assessed with Montreal Cognitive Assessment (MoCA), and the patients were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE) additionally. Results:When hand back, hand palm and alphabets worked as visual stimulus, the response accuracy was less in the patients than in the controls (F > 7.027, P < 0.05). For all the tests, the reaction time was more in the patients than in the controls (F > 14.827, P < 0.001). The main effect of rotation angle was significant to reaction time when picture of hands as visual stimulus (F > 7.747, P < 0.001), while it was the least at 0°. The MoCA scores negatively correlated with reaction time in both groups (r < -0.375, P < 0.05), as well as the FMA-UE scores in the patients (r < -0.581, P < 0.05). Conclusion:Different types of visual stimulus may affect the judgment strategies and results of mental rotation test. Motor imagery ability is impaired for stroke patients, however, the basic reaction model maintains somehow.
ABSTRACT
<p><b>OBJECTIVE</b>To propose a square's ring motion stimulation based on steady-state motion visual evoked potential, and compare it with the commonly used visual stimulation modes (Newton's ring motion, square flicker and circular flicker).</p><p><b>METHODS</b>EEG signals were collected while 9 experimental subjects gazing at four stimulation and pattern analyzed by Canonical Correlation Analysis (CCA). Stimulation were evaluated by recognition accuracy and subjective scores.</p><p><b>RESULTS</b>The classification accuracies of SSVEP elicited by the square's ring motion(82.8%±14.1%) and Newton's ring(83.3%±11.5%) have no significant difference between them, which are lower than that of the square flicker(98.3%±4.1%) and the circular flicker(99.2%±1.8%). The shape of the figure has no significant influence on the classification accuracy either in motion mode or flicker mode. The comfort of the square's ring motion is higher than the other three stimulation according to subjective scores.</p><p><b>CONCLUSIONS</b>The square's ring motion can elicit EEG and reduce the discomfort caused by flicker modes. The square's ring motion can be used as a visual stimulation in SSMVEP-based BCI system.</p>

ABSTRACT
Se realizó un estudio de intervención terapéutica en 128 niños ambliopes, pertenecientes al Círculo Infantil de Atención Especial "Pulgarcito" de Santiago de Cuba, desde septiembre del 2013 hasta julio del 2014, con vistas a demostrar la efectividad de la estimulación visual temprana y desarrollar habilidades al respecto. No hubo diferencias significativas entre ambos sexos. El estrabismo constituyó la primera causa de ambliopía y se obtuvieron mejores resultados en los niños que fueron tratados precozmente. La estimulación temprana fue efectiva para desarrollar habilidades en el orden visual, mediante un tratamiento médico - pedagógico que favoreció la incorporación de estos niños a la familia, la escuela y la sociedad de forma armónica. Se recomendó efectuar pesquisa en menores de 2 años que no asistan a círculos infantiles para diagnosticar tempranamente la ambliopía y así poder controlar la ceguera evitable.
A therapeutic intervention study in 128 amblyopic children, belonging to "Pulgarcito" Special Care Day-care Center in Santiago de Cuba was carried out from September, 2013 to July, 2014, with the aim of demonstrating the effectiveness of the early visual stimulation and to develop abilities on this respect. There were not significant differences between both sexes. Strabismus constituted the first cause of amblyopia and better results were obtained in the early treated children. The early stimulation was effective to develop abilities in the visual order, by means of a medical - pedagogical treatment that favored the incorporation from these children to the family, school and society in a harmonic way. It was recommended to make an screening in children under 2 years who don´t attend day-care centers to diagnose amblyopia early and this way to control the avoidable blindness.

Abstract Introduction In this work, the effect of a dynamic visual stimulation (DS) protocol was used to induce egomotion, the center of pressure (COP) displacement response. Methods DS was developed concerning the scenario structure (chessboard-pattern floor and furniture) and luminance. To move the scenario in a discrete forward (or backward) direction, the furniture is expanded (or reduced) and the black and white background is reversed during floor translation while the luminance is increased (or reduced) by steps of 2 cd/m2. This protocol was evaluated using COP signals from 29 healthy volunteers: standing on a force platform observing the virtual scene (1.72 × 1.16 m) projected 1 m ahead (visual incidence angle: θl = 81.4° and θv = 60.2°), which moves with constant velocity (2 m/s) during 250 ms. A set of 100 DS was applied in random order, interspersed by a 10 s of static scene. Results The Tukey post-hoc test (p < 0.001) indicated egomotion in the same direction of DS. COP displacement increased over stimulation (8.4 ± 1.7 to 22.6 ±5.3 mm), as well as time to recover stability (4.1 ± 0.4 to 7.2 ± 0.6 s). The peak of egomotion during DSF occurred 200 ms after DSB (Wilcoxon, p = 0.002). Conclusion The dynamic configuration of this protocol establishes virtual flow effects of linear egomotion dependent on the direction of the dynamic visual stimulation. This finding indicates the potential application of the proposed virtual dynamic stimulation protocol to investigate the cortical visual evoked response in postural control studies.

PURPOSE: To investigate the locations of the cerebral cortex activated by visually stimulated sexual arousal, and to discriminate the gender differences between the cortical activation patterns in response to sexual stimuli. MATERIALS AND METHODS: Thirty-two male and the twenty-one female volunteers from right-handed medical students were enrolled in this study. The electroencephalography (EEGs) included the segments recorded during resting, watching a music-video, intermission and watching a pornographic video. The low-resolution brain electromagnetic tomography (LORETA) images of cross-spectral analysis were obtained from the segments using the LORETA-KEY software. RESULTS: The beta 1, 2 and 3 activities of males showed the point of maximal current densities in both the uncus and parahippocampal gyrus of the left limbic lobe, the anterior cingulate of the right limbic lobe, the superior temporal gyrus of both temporal lobes, the precuneus of the right parietal lobe, the medial frontal gyrus and superior frontal gyrus of the right frontal lobe, the superior parietal lobule of the right parietal lobe, and the middle occipital gyrus of both occipital lobes. The delta, theta, alpha and beta 1 activities of females showed the point of maximal current densities in the postcentral gyrus and inferior parietal lobule of the left parietal lobe, the middle frontal gyrus of the left frontal lobe, the middle occipital gyrus of the left occipital lobe, the left cuneus, the superior temporal gyrus of both temporal lobes and the left parahippocampal gyrus. CONCLUSIONS: There was a difference in the visually stimulated sexual arousal-associated with the cerebral neuroanatomical areas between men and women, as estimated using the LORETA software. These areas; therefore, were thought to play important roles in the sexual arousal of males and females in response to audiovisual sexual stimulation.

PURPOSE: Low resolution brain electromagnetic tomography (LORETA) is a kind of functional imaging technique and it is also an up-to-date technique for conducting electroencephalography (EEG) analysis. We tried to investigate the locations on the cerebral cortex that are activated by visually stimulated sexual arousal. MATERIALS AND METHODS: Thirty-three male volunteers (age range: 24.7+/-1.7 years) among all the right-handed medical students at our university were enrolled in this study. The EEGs included the segments recorded during resting, watching a music-video, intermission and watching a porno-video. The LORETA images of the cross-spectral analysis were obtained with using segments of LORETA-KEY (KEY Institute for Brain-Mind Research, Switzerland) software. RESULTS: In the statistical nonparametric maps (SnPM) of each spectrum and the delta, theta and alpha waves did not show the increased current density. The beta 1, 2 and 3 activity showed the point of maximal current densities in the anterior parahippocampal gyrus of the left limbic lobe and the superior temporal gyrus of both temporal lobes, the superior temporal gyrus of the right temporal lobe, the precuneus of the right parietal lobe, the medial frontal gyrus of the left frontal lobe, the middle occipital gyrus of the right occipital lobe, the superior temporal gyrus of both temporal lobes and the superior frontal gyrus of the right frontal lobe. CONCLUSIONS: The sexual arousal by visual stimulation may activate the anterior parahippocampal gyrus of the left limbic lobe, the superior temporal gyrus of both temporal lobes, the precuneus of the right parietal lobe, the medial frontal gyrus of the left frontal gyrus, and the middle occipital gyrus of the right occipital lobe.

A baixa visão e uma condição em que existe comprometimento das funções visuais, mesmo com a utilização de correções ópticas. A criança com baixa visão pode apresentar alterações da acuidade visual, do campo visual, da sensibilidade ao contraste, visão de cores e da adaptação a luminosidade. Esta revisão objetiva mostrar a atuação do terapeuta ocupacional na intervenção precoce de crianças com baixa visão, utilizando a estimulação visual como recurso. Crianças com baixa visão, alem das alterações visuais, sofrem também prejuízo em seu desenvolvimento sensório-motor e nos relacionamentos sociais. A fim de trabalhar esses aspectos, o terapeuta ocupacional utiliza na intervenção precoce o recurso da estimulação visual, que vai exercitar a visão remanescente, estimular os demais sentidos, reduzir os maneirismos, desenvolver as habilidades motoras, promover a independência e trabalhar o relacionamento da criança com sua família. Por se tratar de profissional capacitado para intervir nas diferentes áreas do desenvolvimento infantil, o terapeuta ocupacional pode fazer use da estimulação visual a fim de evitar atraso no desenvolvimento global da criança e proporcionar melhor qualidade de vida.
Low vision is a condition where a commitment of the visual functions exists, even with the use of optic corrections. The child with low vision can present alterations of the visual quality, visual field, sensibility to contrast, vision of colors, and adaptation to luminosity. This article objective is to show the performance of the occupational therapist in the early intervention of children with low vision, using as a resource visual stimulation. It is evidenced that in children with low vision, beside the visual alterations, also their sensorimotor development and social relationships are involved. In order to work these aspects, the occupational therapist uses in the early intervention a resource called visual stimulation, that will exercise the remaining vision, stimulate the other senses, reduce the mannerismsl develop the motor abilities, promote independence and work the relationship between the child and his/her family. Since it deals with a professional who is able to intervene in different areas of children development, the occupational therapist can make use of the visual stimulation in order to prevent delay in the child global development, and to provide a better quality of life.

PURPOSE: The AVSS with 3-D HMD is considered to provide a more realistic image and more comfortable circumstances in which the subjects are absorbed in the stimulation. We investigated the efficacy of using 3-D combined with oral medication and a stimulation (COS) test for the evaluation of vasculogenic erectile dysfunction (ED). MATERIALS AND METHODS: 66 patients with complaints of ED, 28 patients diagnosed with vasculogenic ED and 38 patients diagnosed with psychogenic ED were included in this study. The patients were randomly divided into the 2-D group and the 3-D group. The 2-D group patients were examined with using 2-D combined an injection and a stimulation (CIS) test. The 3-D group patients were examined with 3-D CIS test. Then a week later, the patients underwent the AVSS with 3-D HMD 1 hour after oral PDE 5 inhibitor medication. The degree of erection was monitored using the Nocturnal Electrobioimpedance Volumetric Assessment (NEVA) system. RESULTS: On the 2-D CIS tests, 12 of 27 patients showed normal erection, and this resulted in a sensitivity and specificity of 72.7% and 56.3%, respectively. On the 3-D CIS tests, 20 of 39 patients showed normal erection and on the 3-D COS tests, 17 patients showed normal erection and this resulted in a sensitivity and specificity of 88.2% and 81.8%, and 94.1% and 72.7%, respectively. No significant difference were present in the results of the diagnosis between the 3-D CIS and 3-D COS tests. CONCLUSIONS: Both the 3-D CIS and 3-D COS tests offer the advantage of higher sensitivity and specificity than the conventional CIS test. The 3-D COS test may be used as a substitute for the conventional CIS test due to its simplicity and less invasive nature.

BACKGROUND: Sympathetic skin response (SSR) is a transient change in the electrical potential of the skin that is evoked by internal or external stimuli. In the present study, our purpose was to compare electrical and visual stimulation methods of evoking a SSR. METHODS: SSRs evoked by both electrical and visual stimulation were recorded from the palm and sole from 48 healthy volunteers. RESULTS: SSRs were obtained in all normal control subjects following both electrical and visual stimulation. The latency of SSR following electrical stimulation was 1383.75+/-223.56 msec at the palm and 1790.54+/-318.70 msec at the sole, and that following visual stimulation was 1518.75+/-252.64 msec at the palm and 1930.10+/-226.19 msec at the sole. The latencies of SSRs following visual stimulation were prolonged significantly more than those following electrical stimulation. The amplitudes of SSRs following visual stimulation were significantly lower than those following electrical stimulation, and the amplitude of SSRs following both electrical and visual stimulation had marked intersubject and intrasubject variabilities in each of the stimulations. CONCLUSIONS: The SSR evoked by visual stimulation is as reliable as known electrical stimulation for determining sympathetic functions and is a less invasive method. Latencies by visual stimulation are longer than those by electrical stimulation in both the palm and sole. The visual stimulation method of evoking a SSR is not influenced by an ascending somatosensory pathway theoretically, so we can postulate that it reflects a purely autonomic function if there is no problem in the visual pathway.

The purpose of this study was to identify the effect on improvement of the Activity of Daily Living (ADL) and decrease the cognitive function and agitation behaviors by reminiscence with audio-visual stimulation for senile dementia. The quasi-experimental design was used in this study. Subjects were 26 with mild senile dementia who were cared for at a Day Care Center for Dementia in Seoul. The data were collected from March to July, 1999. Subjects were divided into three groups: Control I group with 10 subjects, reminiscence group(Control II group with 8 subjects), and reminiscence with audio-visual stimulation group(experimental group with 8 subjects). The Control I group got routine care as usual. Control II group participated in reminiscence sessions for one hour a day, five times a week , for a period of 4 weeks. The experimental group participated in reminiscence with audio-visual stimulation sessions for one hour a day, five times a week, for a period of 4 weeks. Instruments of this study were color photography with sound that was developed through an open questionnaire about events, objects, humans in action and animals that 100 Korean elderly over 60 would like to memorize. This was referred from the Sensory Stimuli Package by Namazi and Haynes(1994). The effects of treatment was evaluated through MMSE-K by Kwon & Park(1989). Also the Brief Cognitive Rating Scale(BCRS) by Reisberg et al(1983) for the cognitive function, through Agitation Inventory by Cohen- Mansfield and Colleague(1989) for behavioral response and through the Rapid Disability Rating Scale-2(RDRS-2) by Linn & Linn(1982) for the activity of daily living respectively. Data analysis was done using SPSS for X2-test, ANOVA, repeated measures ANOVA. The results were as follows : 1. Reminiscence with audio-visual stimulation did not improve cognitive function for senile dementia, but significantly improved verbal expression, the subscale of cognitive function. 2. Reminiscence with audio-visual stimulation reduced agitation behavior of experimental group significantly, but there was no significant difference between groups. 3. Reminiscence with audio-visual stimulation did not significantly effect the activity of daily living after treatment. In conclusion, it was shown that the reminiscence with audio-visual stimulation was an effective therapy to improve verbal expression and to reduce agitation behaviors of senile dementia. Further research with more indepth approach is needed, considering characteristic and level individualized for each senile dementia.
