Using Intersubject Correlation (ISC) of Dance to Study Biological Motion Processing in Autism
More information Time 14:30 - 14:30Location Arthur and Rochelle Belfer Building for Biomedical ResearchLecturer Prof. Frank Pollick, School of Psychology, University of Glasgow, Scotland Organizer Department of Brain SciencesContact Abstract Show full text abstract about Several recent papers have used the technique of Intersubjec...» Several recent papers have used the technique of Intersubject Correlation (ISC) of fMRI data to study differences between typical individuals and those on the autism spectrum when they watch movies while being scanned (Byrge, et al., 2015; Salmi et al., 2013; Hasson et al., 2009). In this presentation I discuss preliminary results from a study using ISC of solo dances that explored the differences in biological motion processing in autism noted previously by our lab (McKay, et al., 2012). This will include introductory discussion of ISC studies of dance that have highlighted the possible confounding effect of using edited videos composed of different camera views (Herbec et al., 2015) as well as the motion signal that appears related to regions of highest ISC (Noble et al., 2014; Jola et al., 2013). -

Dept. of Clinical Neurosciences, Univ. of Cambridge, UKOrganizer Department of Biomolecular SciencesContact Abstract Show full text abstract about Every cell in the body has its own molecular 24 hour clock, ...» Every cell in the body has its own molecular 24 hour clock, allowing it to coordinate its daily activities, just as we use a watch to organise our daily lives. This fact has become more and more important as we live in a "24/7 culture”, with transatlantic air travel and shift-work being part of normal life for an estimated 25% of Europeans. Desynchronizations that disrupt our daily clock, and thus our regular physiology, are now linked to diseases such as diabetes, obesity, neurodegeneration and cancer.
We have uncovered novel mechanisms about how the clock functions to maintain 24 hour time. Our work in red blood cells and marine algae has exposed the surprising and unanticipated role of redox (chemical) oscillations as key drivers in cellular timing. A family of proteins called the peroxiredoxins are a key readout of the clockwork, and their circadian oscillation is, remarkably, conserved in all phylogenetic domains of life, including Bacteria, Archaea and Eukaryotes. Thus, redox mechanisms are deeply embedded within the clockwork of multiple species, in stark contrast to the lack of evolutionary conservation of transcriptional components of the clockwork. Indeed, targeting redox oscillations using novel compounds directed towards peroxiredoxin proteins provides a new route to modifying 24 hour oscillations for potential health gains in multiple organ systems.
Metabolic and redox processes in cells are thus intimately linked to the clockwork, and in particular we have recently found that the redox-sensitive transcription factor NRF2 is an important communication route linking redox and transcriptional rhythms.

Turbulent landscapes of pheromones during olfactory searches
More information Time 11:15 - 12:30Location Edna and K.B. Weissman Building of Physical SciencesLecturer Massimo Vergassola
UCSDOrganizer Faculty of PhysicsContact Abstract Show full text abstract about The olfactory system of male moths is exquisitely sensitive ...» The olfactory system of male moths is exquisitely sensitive to pheromones emitted by females and transported in the environment by atmospheric turbulence. Moths respond to minute amounts of pheromones and their behavior is sensitive to the fine-scale structure of turbulent plumes where pheromone concentration is detectible. The resulting signal of pheromone de-tections is qualitatively known to be intermittent and sporadic, yet quantitative characteriza-tion of its statistical properties is lacking. Such information would be particularly relevant for the design of olfactory stimulators, reproducing physiological signals in well-controlled labora-tory conditions. I shall discuss a Lagrangian approach to the transport of pheromones by tur-bulent flows. Predictions for the statistics of odor detection during olfactory searches will be presented. The theory yields explicit probability distributions for the intensity and the duration of pheromone detections, as well as their spacing in time. Predictions are tested by using numerical simulations, laboratory experiments and field data for the atmospheric surface layer. Consequences for the dynamics of olfactory searches will follow. -

Population receptive fields in the human ventral stream and their role in face perception
More information Time 12:30 - 12:30Location Gerhard M.J. Schmidt Lecture HallLecturer Prof. Kalanit Grill-Spector
Dept of Psychology and Stanford Neurosciences Institute Stanford University, CAOrganizer Department of Brain SciencesContact Abstract Show full text abstract about The cortical system for processing faces is a model system f...» The cortical system for processing faces is a model system for studying the functional neuroanatomy of ventral temporal cortex and its role in perception for two reasons. First, the functional organization of the cortical face system is well understood. Second, activations in ventral face-selective regions are causally related to face perception. Here, I will describe recent results from our research elucidating the computations performed by population receptive field (pRFs) in the cortical system for face perception. In contrast to predictions of classical theories, recent data from my lab reveals that computations in face-selective regions in human ventral temporal cortex can be characterized with a computational pRF model, which predicts the location and spatial extent of the visual field that is processed by the neural population in a voxel. Our research characterizes pRF properties of ventral face-selective regions revealing three main findings. First, pRFs illustrate a hierarchical organization within the face system, whereby pRFs become larger and more foveal across the ventral hierarchy. Second, attention to faces modulates pRFs in face-selective regions, consequently enhancing the representation of faces in the peripheral visual field where visual acuity is the lowest. Third, our research shows that pRF properties in face-selective regions are behaviorally relevant. We find that face perception abilities are correlated with pRF properties: participants with larger pRFs perform better in face recognition than participants with smaller pRFs. These data suggest that computations performed by pRFs in face-selective regions may form a neural basis for holistic processing necessary for face recognition. Overall, these data highlight the importance of elucidating computational properties of neural populations in ventral temporal cortex as they offer a new mechanistic understanding of high-level visual processes such as face perception.
