The brain is a network. We want to know how the activity of neurons in one part of the network depends on and relates to the rest of the network.

Coordination
Even an act as simple as looking and reaching to pick up a cup recruits neurons throughout the brain. What are these neurons saying to each other? Read More…

Decision-making
Neurons in different regions of the brain have access to different kinds of information. When we are faced with a choice, the different regions exchange information with each other. Who decides? Read More…

Speech
Language is a uniquely human property of the brain but speaking depends on constructing a sensory-motor interface, something all brains must do. How are our brains unique? Read More…

Our next steps are to study neural population dynamics during gaze-anchoring, image and manipulate the different cell-types in this circuit, and investigate how multiregional beta coherence is orchestrated by the prefrontal cortices.
These results highlight how spike timing at the 20ms time-scale is critical to explaining behavioral flexibility and variations in movement performance due to cognitive mechanisms that recruit inhibitory multiregional communication.
We tested the channel-modulation hypothesis by predicting the firing of area LIP neurons trial by trial using PRR neuron firing which determines the input gain, and the beta coherence which determines the modulation state. Beta coherence may modulate feedforward inhibition. pic.twitter.com/AvmFnGrNfg
