The field of optogenetics has furthered the fundamental scientific understanding of how specific cell types contribute to the function of biological tissues such as neural circuits in vivo. On the clinical side, optogenetics-driven research has led to insights into Parkinson's disease and other neurological and psychiatric disorders such as autism, Schizophrenia, drug abuse, anxiety, and de… WebRecent advances in upconversion technology have enabled optogenetic neural stimulation using remotely applied optical signals, but limited success has been demonstrated for neural inhibition by using this method, primarily due to the much higher optical power and more red-shifted excitation spectrum that are required to work with the appropriate …

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 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 ). Webparvalbumin-positive interneurons with optogenetic stimulation triggered by observed pyramidal neuron spikes, thereby imple-menting circuit-level feedback inhibition (Figure 1D). Closed-loop optogenetic technology was crucial in demonstrating that the natural firing patterns of pyramidal cells could directly buffalo shooting killer parents
