Basal ganglia: structure and computations

Incidental learning of rewarded associations bolsters learning on an associative task.

“…These findings are consistent with current models of the basal ganglia, where dopamine acts as a teaching signal to train the dorsal striatum to make accurate and efficient responses (Frank, 2005;Wickens, 1997). Although we did not measure neural activity in our experiments, the current results are consistent with gradual basal-ganglia mediated learning (Ashby & Maddox, 2011;Delgado et al, 2005;Frank, 2005;Galvan et al, 2005;Palminteri et al, 2011;Palminteri et al, 2009).…”

Neuropsychological mechanisms of interval timing behavior

“…Figure 3. The components of Miall's beat frequency model of timing(37) are remarkably similar to Houk's coincidence detection hypothesis regarding the function of the striatum (48,49). We have proposed an integration of these ideas in order to more accurately model the mechanisms of interval timing.…”

Identifying Neurobiological Phenotypes Associated with Alcohol Use Disorder Severity

“…Dorsal striatal circuits project and interact with supplementary motor areas involved in motor responses and planning. Specifically, it is believed that GABAergic cell bodies in the dorsal striatum project to the globus pallidus, and activation of these cells results in a disinhibition of the thalamus, allowing sensory input to flow to motor control regions of frontal cortex Wickens, 1997). Given that we found both dorsal striatum and presupplementary motor area in our main contrast, this may suggest that functional connectivity between these regions is enhanced as a result of habit learning.…”
