Abstract:
Associative memory is one of the oldest artificial neural network (ANN) paradigms. The hippocampus, whose one of its functional roles is the storage and recall of episodic memories, is one of the most widely studied of brain regions, yielding a wealth of data on network architecture, cell types, the anatomy and membrane properties of pyramidal cells and interneurons, and synaptic plasticity. Understanding the functional roles of different families of hippocampal neurons in information processing, synaptic plasticity and network oscillations poses a great challenge. Computational and mathematical models play an instrumental role in exploring such functions. I will present a biophysical model of associative memory with particular emphasis on the operations performed by the diverse (inter)neurons in encoding and retrieval of memories in the hippocampus.
