Neural codes for representation and memory
A lecture by Ila Fiete
Department of Neuroscience, College of Natural Sciences
University of Texas at Austin
Neurons and synapses — the fundamental components of representation and communication in the brain — are forgetful and noisy. How does the brain overcome these features to perform accurate computation and generate reliable short-term memory over time scales exceeding the biophysical by factors of up to a thousand? Because of the difficulty of probing neural circuits, classical theoretical ideas on how the brain solves these problems have barely progressed beyond analogy.
During this lecture, Ila Fiete will describe how recent experimental discoveries and analyses finally substantiate some of these proposed ideas. What’s more, the same body of results clearly points to coding strategies in the brain that go far beyond the current theoretical understanding of neural codes.
Fiete will explore the existence of a new class of neural codes that could have excellent performance with neuron number compared with the polynomial performance of most known existing neural codes. Fiete will also argue that while information-theoretic quantities have long been used as yardsticks to measure ‘how much’ information is contained in a given neural representation, it is time to develop and apply information-theoretic principles for coding in the noisy brain.
