Commonly it has been supposed that the coding by neuronal firing for the various percepts recognized by a brain is in complex distributed patterns of firing. However, in recent years it has increasingly been found that there are also neurons that respond very simply, in a wide variety of organisms from birds to primates, both non-human and human. For example, there are neurons that fire exactly at one moment in the song of a zebra finch, and there are neurons that fire when a human sees an image of one particular person. We aim at understanding the algorithms in which these neurons participate, and to relate these to the properties of individual neurons. How do neurons create the complex sequences in birdsong? How are memories formed? How are they represented? Possible algorithms are highly constrained in order that large amounts of information can be processed and stored without running out of space.
