Simultaneous Eye Tracking and Single-Neuron Recording to Identify Target-Selective Neurons

Source: Wang, S., et al. Simultaneous Eye Tracking and Single-Neuron Recordings in Human Epilepsy Patients. J. Vis. Exp. (2019). The video demonstrates an assay to identify target-selective neurons via simultaneous eye-tracking and single-neuron recordings. A human participant is tasked with identifying a target object among an array of objects in a display, and the eye movement is tracked. Simultaneously, single neurons' firing rate is recorded via electrodes implanted in the brain. The data from both recordings are correlated to assess the presence of target-selective neurons.
