[Anatomic and topographic models of the cerebral areas that activates during the linguistic functions]. / Modelos anatomotopográficos de las áreas cerebrales que se activan durante la función lingüística.

AIM: A brief revision was performed in order to develop a topographic model of cerebral activation during silent reading, syllable's repetition and emotional prosody, based in recent neuroimaging studies. DEVELOPMENT: It has been reported that the words are analyzed in both occipital hemispheres during silent reading, after they are 'written' in the right temporal cortex while the integration of the semantic and phonologic processes are integrated on different left temporal areas and also in the left frontal lower part. The understanding is achieved in the left-middle temporal cortex. In the other hand, activation during articulatory movements is carried out in the left supratemporal gyrus and the left motor and premotor cortex, the left putamen and part of both hemispheres of the cerebellum. Finally, recognition of the emotional prosody occurs in three stages: obtaining of the acoustic information in some areas of the right temporal lobe, representation of acoustic sequences in the right posterio-superior temporal area, and an evaluation of the emotional prosody in the lower frontal bilateral cortex, with the involvement of the basal ganglia in the emotional expression. CONCLUSIONS: The location and synchrony of the areas that activate during the language processing is lateralized toward the left hemisphere and it involves cortical and subcortical areas, except for the emotional prosody. The understanding of the language processes will open the field for to take advantage of the plastic mechanisms for the speech therapy and rehabilitation.

The legacy of the radiology residency of the Los Angeles College of chiropractic since 1978.

The radiology residence of the Los Angeles College of Chiropractic (LACC) has produced thirty-four graduates since being completely reworked in 1978 by Joseph W. Howe, D.C., D.A.C.B.R. A residency did exist before he arrived, having left the department chair position at National College of Chiropractic, but it was not very strong. Howe upgraded facilities, created opportunities for residents to study with some of the most eminent radiologists in the world and expanded the program to include up to six residents at any one time. The graduates of this program have had a profound effect on the profession, having taken positions in teaching, college administration, private clinical practice, private radiology, practice, and combinations thereof. Combined, they have published several books and book chapters and hundreds of papers in scholarly journals and trade publications

Laid to uneasy rest: D.D. Palmer, 1913.

A study of the documentary records related to D.D. Palmer's death in Los Angeles in 1913 provided several surprises and a number of unanswered questions. How tall was D.D. Palmer? Why were the Founder's attending physicians persuaded to change their opinions about the primary cause of death? Was there a private autopsy, and what of the reported abscess in Palmer's side? What role did D.D.'s widow play in the patricide controversy? There is more to the documentary trail to explore.
