CHAPTER 9
Synaptogenesis: formation of new synapses, necessary for formation of memories
Neurogenesis: formation of new neurons -hippocampus, olfactory bulbs: high levels of
neurogenesis, other areas have less
Apoptosis: pre-programmed cell death
Necrosis: unprogrammed cell death- by accident, injury, etc
CHAPTER 11: LEARNING AND MEMORY
H.M.: underwent medial temporal lobotomy (removed hippocampus) to stop seizures, lost ability
to form new memories
1)medial temporal lobes involved in memory
2)STM, remote memory and LTM are distinctly separate
Consolidation: moving memories to STM to LTM
3)explicit vs implicit memories exist (explicit=conscious, implicit=unconscious)
Amnesia: deficit in long-term memory
Retrograde amnesia: condition where people lose past memories (personal info, events, facts,
etc)
Anterograde amnesia: loss of ability to form new memories
Prefrontal cortex: working memory
Hippocampus: spatial memory
Temporal lobe: declarative memory
Amygdala: fear based
