Cortico-basal ganglia-thalamic-cortico loop
Action selection within each loop is an emergent property of the interaction of the
direct and hyper direct pathways. Information flows from one loop to another is
via divergence and reconvergence of the direct pathway. Each direct pathway
loop diverges from cortex to associative areas of striatum. The associative striatum
then has outputs to both motor and cognitive GPi. The action selection made
in the cognitive corticostriatal loop is passed to the motor corticostriatal loop via
this divergence and convergence and is used to bias the motor decision.
Within each loop, separate channels represent the decision choices at that level.
Competition for expression occurs between these channels at each level. Association
cortex projects to associative striatum (purple), but is not involved in a
closed feedback loop. Expansions of inputs to each structure are shown in circles.
To avoid confusion, only the inputs are shown; the outputs can be deduced from
the main diagram.
The expansions of cortex and STN show simple 1:1 excitatory inputs. The expansion
of the striatum shows 2 cognitive corticostriatal neurons (in blue), each diverging
to innervate 2 associative striatal neurons, 2 motor corticostriatal neurons
(in red), diverging to innervate a different set of associative striatal neurons, and
an associative corticostriatal neuron (in purple) innervating a single associative
striatal neuron. Inputs from cognitive (motor) cortex to cognitive (motor) striatum
