On body-environment continuities from a laboratory commensalism.

The article attends to everyday practices in a laboratory of neural genetics that studies olfaction, with the fruit fly as its model organism. Practices in neural genetics exhibit one of the 'post' aspects in post-genomic science - a turn to the environment. To get at how laboratory members engage body-environment continuities, I pay attention to an occasion of designing experimental chambers for an optogenetics study. As practitioners deal with the body's continuities with the world by engaging the spatial character of olfaction, their accounts exhibit qualities of feelings of immediate experience, relatable to C.S. Peirce's phenomenological category of Firstness. While these traces of Firstness inevitably manifest themselves in mixtures with the other two of Peirce's categories - namely, Secondness and Thirdness - noticing them allows for an engagement of the environment that goes beyond action and meaning. I reflect on that environment by considering the involvement of scientists' bodies in life with flies, while not forgetting my inhabitation of the laboratory space. Rather than relying on a cross-mapping of attributes known from the human sphere (intentional states or features of the human body) while managing a measurable space observed from the outside, this is an environment lived from within and with others. I conclude the article by proposing its noticing as an orientation toward ecological preoccupations.

Beyond intersubjectivity in olfactory psychophysics I: Troubles with the Subject.

This article provides an experience-oriented relational account that goes beyond a human control of the world. Rather than working with the notion of intersubjectivity (commonly evoked in sensory STS, and still conserving the subject/object opposition), the article reports on how the sense of smell affords a rethinking of our relationship with the world. It does so by challenging the assumption of olfactory ineffability as it turns to a place whose inhabitants speak about smell as a part of their everyday affairs: a laboratory of olfactory psychophysics. There, we attend to a multimodal, embodied language that participates in preparing, running and analyzing scientific experiments. While Western languages are short on specialized vocabulary for expressing olfactory qualities and it feels difficult to talk about smell, laboratory events manifest smell language in its enmeshing with the sensory realm and the world. Noticing these ties destabilizes the idea of agential subject, highlighting instead our pre-intentional sensibility, in its connection with the world. A sister article on 'troubles with the Object' (Alac, 2020) continues to argue that the notion of intersubjectivity is overly narrow, highlighting our immersion in the world (rather than assuming our dominance of it).

Beyond intersubjectivity in olfactory psychophysics II: Troubles with the Object.

This article takes advantage of the sense of smell's peculiar spatiality to reflect on how we may render our engagement with the world other than through manipulating well-defined objects. The lived spatiality associated with olfaction is not reducible to the known parameters of 'distant observation' and 'reaching toward', familiar from the visual and tactile modalities. Instead, olfactory spatiality is one of immersion: Odors ask us to give up our dominance while we continue to be involved. The article attends to this immersive quality of the sense of smell by tracing multimodal, embodied qualities of mundane events in a laboratory of olfactory psychophysics, also considering the spatial organization of laboratory chambers, and how researchers fashion their bodies while they recognize the frailty of their enterprise. To engage these complexities, the article illustrates an exercise in experimenting with re-production, re-enactment and re-experiencing. While the exercise functions as a reflection on how to orient a laboratory study to non-ocular dimensions of science, the article, in parallel, enquires into semiotic articulations of smell experiences. By pointing out how smell language, rather than being 'mute', speaks the spatial quality of our olfactory experiences, it concludes the argument against the olfactory ineffability, initiated in the sister essay on 'troubles with the Subject'.

When a robot is social: spatial arrangements and multimodal semiotic engagement in the practice of social robotics.

Social roboticists design their robots to function as social agents in interaction with humans and other robots. Although we do not deny that the robot's design features are crucial for attaining this aim, we point to the relevance of spatial organization and coordination between the robot and the humans who interact with it. We recover these interactions through an observational study of a social robotics laboratory and examine them by applying a multimodal interactional analysis to two moments of robotics practice. We describe the vital role of roboticists and of the group of preverbal infants, who are involved in a robot's design activity, and we argue that the robot's social character is intrinsically related to the subtleties of human interactional moves in laboratories of social robotics. This human involvement in the robot's social agency is not simply controlled by individual will. Instead, the human-machine couplings are demanded by the situational dynamics in which the robot is lodged.

Modulation of BOLD response in motion-sensitive lateral temporal cortex by real and fictive motion sentences.

Can linguistic semantics affect neural processing in feature-specific visual regions? Specifically, when we hear a sentence describing a situation that includes motion, do we engage neural processes that are part of the visual perception of motion? How about if a motion verb was used figuratively, not literally? We used fMRI to investigate whether semantic content can "penetrate" and modulate neural populations that are selective to specific visual properties during natural language comprehension. Participants were presented audiovisually with three kinds of sentences: motion sentences ("The wild horse crossed the barren field."), static sentences, ("The black horse stood in the barren field."), and fictive motion sentences ("The hiking trail crossed the barren field."). Motion-sensitive visual areas (MT+) were localized individually in each participant as well as face-selective visual regions (fusiform face area; FFA). MT+ was activated significantly more for motion sentences than the other sentence types. Fictive motion sentences also activated MT+ more than the static sentences. Importantly, no modulation of neural responses was found in FFA. Our findings suggest that the neural substrates of linguistic semantics include early visual areas specifically related to the represented semantics and that figurative uses of motion verbs also engage these neural systems, but to a lesser extent. These data are consistent with a view of language comprehension as an embodied process, with neural substrates as far reaching as early sensory brain areas that are specifically related to the represented semantics.

Moving android: on social robots and body-in-interaction.

Social robotics studies embodied technologies designed for social interaction. This paper examines the implied idea of embodiment using as data a sequence in which practitioners of social robotics are involved in designing a robot's movement. The moments of learning and work in the laboratory enact the social body as material, dynamic, and multiparty: the body-in-interaction. In describing subject-object reconfigurations, the paper explores how the well-known ideas of extending the body with instruments can be applied to a technology designed to function as our surrogate.

Working with brain scans: digital images and gestural interaction in fMRI laboratory.

A significant part of functional magnetic resonance imaging (fMRI) practice in neuroscience is spent in front of computer screens. To investigate the brain neuroscientists work with digital images. This paper recovers practical dealings with brain scans in fMRI laboratories to focus on the achievement of seeing in the digital realm. While looking at brain images, neuroscientists gesture and manipulate digital displays to manage and make sense of their experimental data. Their gestural engagements are seen as dynamical phenomenal objects enacted at the junction between the digital world of technology and the world of embodied action.
