The contribution of low contrast–preferring neurons to information representation in the primary visual cortex after learning

Kimura and Yoshimura (Science Advances) recorded in layer 5 of visual cortex and analyzed single-unit and LFP data from NeuroNexus 2-shank tetrodes (A2x2-tet-3mm-150-150-121) used across multiple penetrations over several days of experiments. They discovered that single neuron and population responses to low-contrast visual stimuli enabled improved perception after training.
