Optogenetic inhibition
WebOptogenetic inhibition of neurons overexpressing CREB was tested for the elicitation of reversible impairment of memory expression (Fig. 7A). The short time course of this manipulation allowed comparison of tone-induced freezing behavior in individual mice in the presence and absence of optical inhibition ( Fig. 7 B ). WebFeb 23, 2024 · It was established that optogenetic inhibition of pyramidal cells (PCs) in dorsal CA1 [] or disinhibition through somatostatin-positive (SST) cells [] reversibly disrupts memory acquisition.Inhibition of CA1 during recall also disrupts recall [].These findings underscored the importance of CA1 and suggested that a precise CA1 function is needed …
