Thalamo-Cortical Alpha
Cortex and thalamus drive each other. Fitted to sleep, it finds spindles at 13.45 Hz in people it never saw (p = 7.2e-11).
One Brain, Many Perspectives
Specify a specific region, resolution, or bandwidth and only the processes and variables that actually matter materialize. The same brain can be coarse everywhere and fine around a single electrode.
M = materialize(R, r, B, F, A, T, P)
Designed to Resonate like the Brain
A brain's rhythms are not decoration laid over its anatomy — they are what a loop with a delay and a gain does. IBM-1 declares the loops themselves: which structures, in which order, with what conduction delay. A band is then a consequence to be checked, not a spectrum to be fitted.
Hippocampal Theta–Gamma
Each slow theta cycle is cut into fast gamma slots, so an episode's order is carried by timing.
Fronto-Parietal Attention
Visual cortex proposes, parietal cortex maps, frontal cortex picks one place to look.
More circuits
Basal ganglia, cerebellum, default mode, arousal, valuation, hearing, vision and movement, each declared as a loop.
Each figure lights the structures the substrate declares for that loop and runs a wave around it. The on-screen rate is a depiction, not a measured frequency.

Whole Body Human Simulation
Every system the atlas carries — skeleton, muscle, vessels, viscera and the skin over them — on one driven skeleton, with the cortex closing the loop out to the muscle and back.
- 13 systemsbone, muscle, fascia, artery, vein, lymph, gut, lung, heart, gland, kidney, reproductive tract and skin, each bound to the segment it rides on.
- 0.17 mmit moves, when you shove it.
- 2.90 sto the floor, with the cortex cut out.
Control: scramble what the cortex learned and it still stands. The cortex owns the muscles; that is not the same as it knowing how to walk.
Predicting TMS Effects on the Brain
- where it landsthe field is solved through skull and scalp, so the answer is a place on the cortex rather than a spot on the head.
- what it does nowthe response every electrode records, milliseconds after the pulse.
- what it does by week fourhow the rhythms of the targeted region reorganise over a course of treatment.
