Evolutionarily conserved mechanisms for the selection and maintenance of behavioural activity

摘要: Survival and reproduction entail the selection of adaptive behavioural repertoires. This manifests as phylogenetically acquired activities that depend on evolved nervous system circuitries. Lorenz Tinbergen already postulated heritable behaviours their reliable performance are specified by genetically determined programs. Here we compare functional anatomy insect central complex vertebrate basal ganglia to illustrate role in mediating maintenance behaviours. Comparative analyses reveal circuitries share comparable lineage relationships within clusters functionally integrated neurons. These genetic mechanisms link birth time order neuronal identities functions. Their subsequent connections associated functions characterized similar implement dimensionality reduction transition through attractor states, whereby spatially organized parallel-projecting loops integrate convey sensorimotor representations select maintain activity. In both taxa, these neural systems modulated dopamine signalling also mediates memory-like processes. The multiplicity similarities between suggests evolutionarily conserved computational for action selection. We speculate may have originated from ancestral ground pattern present brain last common ancestor insects vertebrates.
