Mature takes dude's erect meat pole in her mouth Tags: Separate brain regions code for salience vs. Neuronal activity in the subthalamic nucleus modulates the release of dopamine in the monkey striatum. Differential neuromodulation of acquisition and retrieval of avoidance learning by the lateral habenula and ventral tegmental area. These ACC functions might be supported by a mixture of DA motivational value and salience signals, which will be important to test in future study.

Furthermore, the OFC is involved in learning from negative reward prediction errors Takahashi et al. We hypothesize that these dopaminergic pathways for value, salience, and alerting cooperate to support adaptive behavior. A specialized subclass of interneurons mediates dopaminergic facilitation of amygdala function. In an analogous manner, low DA receptor activation promotes potentiation of cortico-striatal synapses onto the indirect pathway Shen et al. A model for Pavlovian learning:

Adapted from Brischoux et al. Multiple timescales of memory in lateral habenula and dopamine neurons. Thus when motivational cues are presented with unpredictable timing they trigger immediate orienting reactions and a generalized DA alerting response — excitation by all cues including neutral cues Figure 6C , black.

When these DA neurons burst, they would engage the direct pathway to learn to gain reward outcomes; when they pause, they would engage the indirect pathway to learn to avoid aversive outcomes Figure 2.
