Lecture 19

Question	Answer
Karl Lashley	Had rats learn maze and then cut and lesioned parts of the brain to try to find where memory is processed but only found mass action law and equipotentiality law; searched for the circuits of procedural memory in regions mediating memory for declarative information
Mass Action Law	The more brain matter that is destroyed, the more severe the memory deficient
Equipotentiality Law	Specific area of destruction of the brain does not matter
Anterograde amnesia	Cannot form new memories
Retrograde amnesia	Cannot recall past events
Declarative information	Facts; contains episodic, bibliographic, and semantic memory
Procedural information	perceptual and motor information; showing skills or information
Taxonomy of memory	Long term memory is grouped into two different categories
Henry Molaison	Intractable seizures; controlled only by bilateral medial temporal lobectomy = anterograde amnesia, some retrograde amnesia, but short term memory normal
Brenda Milner	Studied H.M.; first to give basis on where to start in research to behavioral neuroscience
Memory system experiment	Performance impaired by temporal lobe lesions; temporal regions much more severe than just hippocampus
Different attributes of memory may be processed by different brain systems	1. Space - Hippocampal formation 2. Time - Hippocampal formation 3. Affect - Amygdala 4. Sensory perception - Extrastriate cortex 5. Reponse - Caudate nucleus
