The mouse primary visual cortex (V1) has become an important brain area for exploring how neural circuits process information. Optogenetic tools have helped to outline the connectivity of a local V1 circuit comprising excitatory pyramidal neurons and several genetically-defined inhibitory interneuron subtypes that express parvalbumin. somatostatin. or vasoactive intestinal peptide. https://lockdownsecuritycanada.shop/product-category/usb-cd-player/
