We use cognitive & biophysical models, EEG, and transcranial ultrasound to study cognition in health and disease. A list of ongoing projects is here:

The positions come with a lot of freedom to develop your own research agenda in this space. Any questions: Email or DM!

These, and other, studies show that you can decode task-related signals from many brain areas.

But wouldn't we need causal manipulations to conclude that the brain "uses" them?

For example, maybe we can decode equally well from two areas. But, only one impacts behaviour when inactivated.
