When one neuron becomes less excitable, its neighbors shift their tuning via lateral inhibition - reshaping the code while keeping downstream readouts stable.

We show how changes in excitability in recurrent networks can drive representational drift - even without changes to synaptic weights.

🔁 Lateral inhibition + slow variations in excitability = representational drift

We contrast learning and evolution, discrete vs continuous control, and short vs long timescale dynamics as important for delineating the respective roles of different brain systems within an integrative take on the neural control of behavior.

"Time, Control, and the Nervous System" - a nod to Weiner’s "Time, Communication, and the Nervous System" - explores how viewing multiarea brain computations through control theory highlights temporal processing as central to our understanding of multiscale adaptive behavior.
