Allen Institute – Contrast tuning in mouse visual cortex with calcium imaging

A two photon calcium imaging dataset from Allen Institute measuring responses to full-field drifting gratings (approx. 120x90 degrees of visual space) of 8 directions and 6 contrasts (5%, 10%, 20%, 40%, 60%, 80%). Mouse Cre lines expressing GCaMP6f were imaged to record responses of pyramidal neurons across cortical layers (Cux2: layer 2/3; Rorb: layer 4; Rbp4: layer 5; Ntsr1: layer 6) as well as inhibitory interneurons (Vip and Sst). All experimental sessions took place on the same data collection pipeline as the Allen Brain Observatory (see http://observatory.brain-map.org/visualcoding) and have the same visual stimulus monitor calibration and positioning, two photon imaging systems and image processing pipeline, and running wheel to track locomotion.
