}The giant cholinergic interneurons of the striatum are tonically active neurons (TANs) that respond with pauses to appetitive and aversive cues and to novel events. Whereas tonic activity emerges from intrinsic properties of these neurons, glutamatergic inputs from intralaminar thalamic nuclei and dopaminergic inputs from midbrain are required for genesis of pause responses. No prior computational models encompass both intrinsic and synaptically gated dynamics. We present a mathematical model…

A local circuit model is simulated to show how learned uncertainty responses are generated, along with phasic RPE responses, on single trials and exhibits the empirically observed dependencies on conditional probability, expected value of reward, and time since onset of the reward-predicting cue.

Recurrent Inhibitory Network among Striatal Cholinergic Interneurons

A novel microcircuit is proposed in the striatum, in which cholinergic interneurons are connected to one another through GABAergic interneeurons, which may provide a mechanism to convert activation of cholinerential interneuron into widespread recurrent inhibition of these neurons via nicotinic excitation of striatal GABAergic neurons.

Data suggest that the TANs respond as do detectors of motivationally relevant events, but they also demonstrate that these neurons are influenced by predictive information based on past experience with a given temporal context, suggesting a unique subset of striatal neurons that might serve a modulatory function, monitoring for temporal relationships between environmental events.
