The reasoning: separate systems, shared plasticity rules
| System | Network | Test |
|---|---|---|
| Working memory | dorsolateral prefrontal + parietal | digit span, serial 7s |
| Episodic | hippocampus, entorhinal cortex, Papez circuit (hippocampus → fornix → mammillary bodies → anterior thalamus → cingulate → parahippocampal → hippocampus) | delayed recall of a word list or story |
| Semantic | anterior temporal lobes, distributed cortex | naming, word meaning |
| Procedural | striatum, cerebellum, motor cortex | skill learning |
| Priming | neocortex | |
| Emotional (fear) conditioning | amygdala |
