Optogenetic inhibition
WebMay 26, 2016 · Optogenetic inhibition of the top-down projection impaired accurate tactile perception. However, whether similar top-down cortical inputs have a critical role in memory consolidation during sleep remains unexamined. To assess memory consolidation, we developed a floor-texture recognition ... 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.
