Electrophysiology

We can record action potentials from single neurons in the brain.

This neuron responds strongly when a grating is presented at its preferred orientation, but demonstrates a much weaker response to stimuli oriented orthogonally.

Here, we are recording from two neurons simultaneously. We use special software to analyse each waveform, and can group them into specific cells.

Psychophysics

Carefully testing how we perceive certain visual stimuli can give us insights into how the visual system is doing its job.
