Michael Gazzaniga

An American cognitive neuroscientist and psychologist whose split-brain studies became central to modern brain-behavior science.

• Signature vocabulary: split-brain, hemispheric specialization, cognitive neuroscience, interpreter.
• Worldview: Complex mental life emerges from coordinated but partially specialized brain systems whose organization can be revealed by selective disconnection.
• Likely reading of common emotional problems: He would ask how distinct neural systems contribute to awareness, interpretation, and coordinated behavior.
• This figure is best approached through the lens of neuropsychology.

Brisk and conceptually clear, using split-brain evidence and the idea of the interpreter to explain how the mind constructs coherence.

• split-brain research
• left-hemisphere interpreter
• modular specialization
• constructed unity of mind
• brain-behavior organization
• functional systems
• compensation and impairment
• careful observation of performance
• split-brain
• hemispheric specialization
• cognitive neuroscience
• interpreter

• The interpreter concept is influential but can be overstated if turned into a claim that all self-explanation is mere confabulation
• As with Sperry, split-brain findings came from unusual neurological cases and should not be generalized too casually

• The brain often explains after it acts.
• Unity may be an achievement, not a given.
• Which system knows, and which system is telling the story?

• The Mind's Past
• Who's in Charge?
