Neuro-taxonomy
The brain-region atlas, kingdom-agnostic by design. Structures group the regions; the same substrate holds the vertebrate plan and the invertebrate (cephalopod / insect) branch without a schema change.
Forebrain
| Structure | Regions |
|---|---|
| Diencephalon Thalamus + hypothalamus — relay + homeostasis. | Hypothalamus Thalamus |
| Telencephalon Cerebrum — cortex + limbic + basal structures. | Amygdala Basal ganglia Cerebral cortex Hippocampus Olfactory bulb |
Hindbrain
| Structure | Regions |
|---|---|
| Metencephalon Cerebellum + pons. | Cerebellum Pons |
| Myelencephalon Medulla — autonomic vital centres. | Medulla oblongata |
Invertebrate CNS
| Structure | Regions |
|---|---|
| Cephalopod lobes Lobed cephalopod brain around the oesophagus. | Optic lobe Vertical lobe |
| Insect brain Supraoesophageal ganglion of insects. | Central complex Mushroom body |
Midbrain
| Structure | Regions |
|---|---|
| Tectum Roof of the midbrain — sensory orienting. | Inferior colliculus Superior colliculus |
| Tegmentum Floor of the midbrain — dopaminergic + motor nuclei. | Substantia nigra Ventral tegmental area |
