Neuromorphic VLSI for Learning and Memory

The hippocampus is a brain region responsible for the storage and retrieval of patterns in space and time. It performs these functions rapidly despite variable and noisy environments. In this program, John Arthur, University of Pennsylvania, explains how to realize these computations in an engineered device he has constructed a VLSI model of the hippocampus that uses mixed analog and digital circuits, achieving real-time performance with low-power consumption. Employing biologically motivated neurons and synapses, the neuromorphic hippocampus validates a system-level model of neurobiological computation and provides a clear path to realize ot...
