About

Nima Dehghani is a physicist and computational neuroscientist at MIT. His group **N⁴** studies how neural systems compute across scales — from cortical microcircuits to coarse-grained representations in deep networks — along four braided axes: NeuroPhysics, NeuroComputation, NeuroDynamics, and the encompassing surface, NeuroAI. The work moves between two registers. One is structural: human intracranial and non-invasive recordings used to ask what, physically, a cortical event *is* — the K-complex as an isolated down-state, sleep spindles as several asynchronous generators rather than one brain-wide wave, the extracellular medium as non-resistive rather than a convenient idealisation. The other is theoretical: treating depth in neural networks as successive coarse-graining, a renormalisation-group flow that preserves task-relevant information while integrating out nuisance. This site is not a CV. It is an epistemic labyrinth — the [Paper Maze](/papers/) holds the discrete rooms; the [Idea Garden](/garden/) holds the concepts that fork between them; [Research](/research/) holds the running argument that ties the two together. ### Contact Email is the surest channel: nima.dehghani@mit.edu.
