Dynamics of Excitatory-Inhibitory neuronal networks

Cortical networks are known to exhibit a moderate and variable level of order in different temporal and spatial scales, meanwhile the individual neurons fire irregularly. This “emergence of collective order from irregular components” is commonly believed to be a consequence of excitation-inhibition ......

Signal transmission and Information transfer in neural circuits

This project has two sides. First is the effect of dynamical properties of the neuronal populations on the transmission of signals and information, and the second explores the effect of structure and in particular, bidirectional connections ....

Learning spatio-temporal patterns through STDP

Neuroscience has known quite much about how the brain learns and recognizes spatial patterns, but there is little knowledge about temporal patterns, sequences.  We are running some toy models to explore how timing-dependent-plasticity rulescan lead to the learningof the temporal patterns....
