Explainers

Neuroscience concepts, each explained once and linked to the ideas that build on it.

Very much under construction

Honestly, these explainers are mostly a pipe dream for now: early plans for a much bigger project. Most pages are just outlines or rough notes, and some may be thin or not work yet. Look around, but expect a sketchbook.

Selected topics

  1. Neuron
  2. Action Potential
  3. Synaptic Communication (coming soon)
  4. Receptive Fields
  5. Sensory Pathways (coming soon)
  6. Sensorimotor Loop (coming soon)
  7. Place Cells
  8. Egocentric vs Allocentric (coming soon)
  9. Cognitive Maps (coming soon)
  10. Memory (coming soon)
  11. Replay (coming soon)
  12. Episodic Forethought and Planning (coming soon)
