Figure Lengend Snippet: A) Example voltage trace of a fast-spiking interneuron (blue) and concurrent LFP (black) during optogenetic stimulation of CaMKIIα+ neurons. B) Filtered gamma frequency LFP component (black) and raster plot of fast-spiking interneuron (blue) from A. C) Resultant vector comparison between stellate (red), pyramidal (green), and fast-spiking interneurons (blue). Left: Individual neurons. Right: Pooled within cell types. D) Pooled gamma spike phase distributions for stellate, pyramidal and fast-spiking interneurons.
Article Snippet: For compatibility with the voltage imaging microscope, a 490 nm LED (Thorlabs, M490L4) delivered widefield sinusoidal optogenetic stimulation through a 16x objective lens.
