Dopamine-modulated dynamic cell assemblies generated by the GABAergic striatal microcircuit [PDF]
, 2009 The striatum, the principal input structure of the basal ganglia, is crucial to both motor control and learning. It receives convergent input from all over the neocortex, hippocampal formation, amygdala and thalamus, and is the primary recipient of ...

The Dopaminergic Midbrain Encodes the Expected Certainty about Desired Outcomes [PDF]
, 2014 Dopamine plays a key role in learning; however, its exact function in decision making and choice remains unclear. Recently, we proposed a generic model based on active (Bayesian) inference wherein dopamine encodes the precision of beliefs about optimal ...
