Welcome to Helmholtz, UNIC's database of electrophysiological recordings in the primary visual cortex of the cat.

There are three main types of object in the database:

Protocol recording
Recordings obtained during a particular experimental protocol in a particular cell. The datafile may contain data from multiple recording channels and from multiple repetitions of the visual stimulus.
Recording block
A group of recordings, generally using multiple protocols, obtained in the same neuron.
Experiment
A group of recording blocks, all from the same animal.
