Episode 66 of the Brain Science Podcast is an interview with Randy Gallistel, PhD, Co-Director of the Rutgers Center for Cognitive Science and co-author (with Adam Philip King) of Memory and the Computational Brain: Why Cognitive Science will Transform Neuroscience. We discuss why read/write memory is an essential element of computation with an emphasis on the animal experiments that support the claim that brains must possess read/write memory. This is significant because current models, such as neural nets, DO NOT incorporate read/write memory in their assumptions about how brains work. It is not necessary to have any background in information theory or computation to appreciate the experiments that are discussed in this episode.
