  6. Mohammad Abdolrahmani is a research scientist in the lab for neural circuits and behavior at RIKEN Center for Brain Science. He previously was a post-doc at Osaka University. Mohammad’s main research interests lie in visual perception, decision making and visually-guided behaviors. He received his undergraduate degree in anatomical sciences from Iran University and his PhD in cognitive neuroscience from Osaka University. SfN Abstract: My poster will be presented at this time (October 23, 2019, 3:00 PM - 4:00 PM) and I will be available then. Perception is an active process involving continuous interactions with the environment. During such interactions neural signals called corollary discharges (CDs) propagate across multiple brain regions informing the animal whether the incoming sensory information originates from animal’s own actions or from the environment. Under ethologically natural conditions, such CDs co-occur in close temporal proximity and interact with each other. However, how the interactions between concurrent CDs affect the large-scale network dynamics, and in turn help shape sensory perception is currently unknown. We focused on the effect of saccadic and body-movement CDs on a network of visual cortical areas in adult mice (n=15). CDs alone had large amplitudes, 3-4 times larger than visual responses, and could be dynamically described as standing waves (singular-value decomposition; explained variance 88±3%). They spread broadly, with peak activations in the medial and anterior parts of the dorsal visual stream. Inhibition (I) mirrored the wave-like dynamics of excitation (E), suggesting these networks remained E/I balanced. A generalized linear model (explained variance 36.8±3.6%) showed that CD waves superimposed sub-linearly and asymmetrically: the suppression was 1.5±0.2 times larger if a saccade followed a body movement by 0.59+-0.05 ms than in the reverse order. These rules depended on the animal’s cognitive state: when the animal was most engaged in a visual discrimination task (measured using pupil area), cortical states had large variability accompanied by an increase in S/N (max amplitude after the stimulus over pre-stimulus variability, p = 0.001) improving the reliability in sensory processing. High-variability states were associated with a smaller non-linearity as well (p = 0.002). These results suggest that in high variability states CDs and sensory signals are independently encoded, permitting an efficient read-out by downstream networks for improved visual perception. In summary, our results highlight a novel cognitive-dependent arithmetic for the interaction of non-visual signals that dominate the activity of occipital cortical networks during goal-oriented behaviors. These findings provide an experimental and theoretical foundation for the study of active visual perception in ethological conditions.

She completed her first postdoctoral training at University of Victoria, BC, Canada. Date and Time that I will be available to answer questions: Tuesday Oct 22, 2019 1:00 PM - 5:00 PM In my project, We develop optogenetic protocols to selectively activate synaptic inputs from CA1 pyramidal cells onto somatostatin interneurons (SOM-INs) using ChR2, and induce long-term potentiation of EPSPs recorded by patch clamp electrodes in slices. We developed the optogenetic stimulation methods using the Polygon Pattern Illumination system. We characterized the optogenetically induced LTP in SOM-INs and showed it was dependent on mGluR1a and mTORC1 signaling. Moreover, We used field potential recordings in hippocampal slices to demonstrate that optogenetically-induced SOM-IN LTP regulates the two output targets of SOMINs: the Schaffer collateral and temporo-ammonic pathways onto CA1 pyramidal cells. Thus, We found that optogenetic activation of CA1 pyramidal inputs is sufficient to induce LTP of SOM-IN afferent synapses, and that long-term plasticity of these inputs, in turn, regulates metaplasticity of CA1 pyramidal cell Schaffer collateral and temporo-ammonic pathways.
