PROJECT TITLE :

How the Brain Formulates Memory: A Spatio-Temporal Model Research Frontier

ABSTRACT:

Memory could be a advanced method across totally different brain regions and a elementary function for several cognitive behaviors. Rising experimental results counsel that reminiscences are represented by populations of neurons and arranged in an exceedingly categorical and hierarchical manner. But, it's still not clear how the neural mechanisms are emulated in computational models. During this paper, we tend to gift a spatio-temporal memory (STM) model using spiking neurons to explore the memory formulation and organization in the brain. Unlike previous approaches, this model employs temporal population codes because the neural representation of data and spiketiming-based learning strategies to formulate the memory structure. It explicitly demonstrates that the advanced spatio-temporal patterns are the internal neural representations of memory items. Two types of memory processes are analyzed and emulated: associative memory, i.e., spatio-temporal patterns driven by intra-assembly connections, and episodic memory, i.e., temporally separated spatio-temporal patterns linked by inter-assembly connections. Our model can give a computational substrate based on lowlevel neural circuits for developing neuromorphic cognitive systems with wide applications.
