The basal ganglia are a hub of interconnected nuclei embedded in an
extensive brain-wide network, controlling movement, mood states,
and higher brain functions.
Their selection-suppression operations serve as a
paradigm in computational biology and neurorobotics.
Basal ganglia dysfunction causes neuropsychiatric
disturbances and movement disorders.
The basal ganglia are evolutionarily
conserved; vertebrate models of
basal ganglia disease are
