Concepts As Internal Representations
- Kate Jeffery defines a concept as an internal representation the brain forms of the external world.
- She distinguishes having representations from consciously reflecting on them, focusing on automatic neural encoding.
No Homunculus In The Brain
- Jeffery rejects a homunculus interpreter and says brain regions interact with each other to produce behaviour.
- Humans can interrogate outputs via language, but animals may not perform high-level consulting of representations.
Rat Experiments That Revealed Maps
- Tolman's experiments suggested rats could take shortcuts and plan detours, implying internal spatial maps.
- O'Keefe's recordings then found hippocampal neurons that fire in particular places, supporting a neural 'map'.
