In Vivo Intracellular Recording of Photoreceptor Cell Spectral Sensitivity in a Butterfly

Source: McCulloch, K. J., et al.. Determination of Photoreceptor Cell Spectral Sensitivity in an Insect Model from In Vivo Intracellular Recordings. J. Vis. Exp. (2016) This video demonstrates the procedure for in vivo intracellular recording of photoreceptor cells in the eye of a butterfly and determining the spectral sensitivity of individual cell types. This technique enables the study of sensitivities of individual photoreceptor cells to different light stimuli.
