Our brain enables the processing of various sensory information around us, thus facilitating effortless interaction with our environment. The brain is unparalleled in its computational abilities of processing sensory information in an adaptive manner. Many real life problems to do with pattern recognition and learning in single or multiple sensory space(s) are solved or learned by the brain easily whereas artificial algorithms struggle to successfully perform even simple behaviors. Our objective is to find the underlying principles by which the brain solves such problems. Specifically, in terms of structure of cortical circuits: since precise nature of connectivity between specific types of neurons in a network determines its function - we ask what is the precise connectivity of neurons of different types (example: excitatory and inhibitory) that form local functional sensory micro-circuits or modules in the cortex; and, in terms of adaptation/learning by such circuits: how does the connectivity of such circuits change over time, at rapid or long (developmental) time scales, depending on cognitive demands or experience. Our research will not only enhance artificial computation but also allow us to understand the specific deficits underlying various learning and developmental disorders (like dyslexia and autism spectrum disorder). We use a variety of techniques to answer questions: 1) In vivo electrophysiology (single and multiple electrodes) 2) Neuroanatomical methods using retrograde and anterograde labeling and viral techniques 3) In vivo and in vitro Ca2+ Imaging 4) Mapping micro-circuitry with optical stimulation 5) Computational Modeling of Neural Computation
