WebOct 5, 2024 · Optogenetic inhibition of sub-populations of pyramidal neurons decreases activity in some neurons (as expected) and increases activity in others. Interneurons are largely inhibited in their activity during inhibition of pyramidal cells. Presumably, this is a result of reduced pyramidal cell excitation of feedback interneurons. ...
WebOptogenetic activation of STN-projecting dmPFC neurons or their axons in the STN markedly improved task performance mainly by reducing the FA rate, whereas inactivating these neurons had the opposite effect. In contrast, bidirectional manipulation of LH-projecting neurons showed that their activity impairs performance by increasing the FA rate.
