Brain rhythms are thought (by some) to be essential for many kinds of cognitive activity, especially communication among different areas of the brain.

In this talk, I will discuss mechanisms of resonance to input frequencies and a role of resonance in filtering and routing of signals, especially when the target network has strong inhibitory feedback. The ideas are discussed in the context of dynamics in the dorsolateral prefrontal cortex and rule-based decisions, with inputs from the anterior cingulate cortex.

I will also talk about how top-down signals to the striatum can bias activity between go and no-go pathways depending on the frequency of the signals.
