The visual system is one of the most well studied systems in neuroscience. Today we know so much more about how vision is represented in the brain than in the 1960s, when Hubel and Wiesel first showed visual responses in the cat visual cortex.

Yet, there is still a lot to be discovered in the visual system. One recent discovery is that there are prominent 3-6 Hz oscillations in the visual cortex, which can be both spontaneous and visually-evoked. The origin and function of this oscillation in the visual system is still unknown. Using the new state-of-the-art tools in the Steinmetz lab, we are investigating this 3-6 Hz oscillation further.
