Abstract: | Learning involves a usually adaptive response to an input (an external stimulus or the organism℉s own behaviour) in which
the input-response relation is memorized; some physical traces of the relation persist and can later be the basis of a more
effective response. Using toy models we show that this characterization applies not only to the paradigmatic case of neural
learning, but also to cellular responses that are based on epigenetic mechanisms of cell memory. The models suggest that the
research agenda of epigenetics needs to be expanded. |
