Connectome — the genome
| Neurons | 10 M (10000000) |
|---|---|
| Synapses | 10 B |
| E/I balance | 80% excitatory / 20% inhibitory |
The connectome genome drives the dynamics model and (eventually) the virtual-world avatar's behaviour — one seed, many surfaces.
Brain regions
| Region | Function |
|---|---|
| Cerebellum region | Motor coordination, balance, timing. |
| Hypothalamus region | Homeostasis, endocrine control, basic drives. |
| Superior colliculus region | Visual orienting and gaze control (optic tectum). |
| Thalamus region | Central sensory + motor relay hub. |
Rhythm spine (EEG)
| Band | Range | Baseline power | |
|---|---|---|---|
| delta | 0.5–4 Hz | 0.22 | |
| theta | 4.0–8 Hz | 0.20 | |
| alpha | 8.0–13 Hz | 0.20 | |
| beta | 13.0–30 Hz | 0.22 | |
| gamma | 30.0–100 Hz | 0.16 |
The rhythm spine is to a brain what the growth spine is to a plant — the deterministic model input. The live strip above samples it over time.
Mind & behaviour
Distilled from the live band mix — the seam that lets this brain drive an NPC (Brain.Mind with emit) or feed the attention pipeline.
