abstract = {Integrating individual actions into coherent, organised
behavioural units, a process called chunking, is a
fundamental, evolutionarily conserved process that renders
actions automatic. In vertebrates, evidence points to the
basal ganglia - a complex network believed to be involved in
action selection - as a key component of action sequence
encoding, although the underlying mechanisms are only just
beginning to be understood. Central pattern generators
control many innate automatic behavioural sequences that
form some of the most basic behaviours in an animal's
repertoire, and in vertebrates, brainstem and spinal pattern
generators are under the control of higher order structures
such as the basal ganglia. Evidence suggests that the basal
ganglia play a crucial role in the concatenation of simpler
behaviours into more complex chunks, in the context of
innate behavioural sequences such as chain grooming in rats,
as well as sequences in which innate capabilities and
learning interact such as birdsong, and sequences that are
learned from scratch, such as lever press sequences in
operant behaviour. It has been proposed that the role of the
striatum, the largest input structure of the basal ganglia,
might lie in selecting and allowing the relevant central
pattern generators to gain access to the motor system in the
correct order, while inhibiting other behaviours. As
behaviours become more complex and flexible, the pattern
generators seem to become more dependent on descending
signals. Indeed, during learning, the striatum itself may
adopt the functional characteristics of a higher order
pattern generator, facilitated at the microcircuit level by
striatal neuropeptides.},
