PSY397H5 Lecture Notes - Tetanus, Flashbulb Memory, Molecular Modification
Document Summary
Flashbulb memory: rise in activity of modulatory inputs acting on and primes pyramidal cells. Ltp: structural modification of the synapse, post and presynaptic terminals gets physically modified. Memory upon recall is a constantly dynamic process (i have to rebuild the house). Therefore any memory can be inaccurate; things get added and removed from it (it can be built quite different). If left alone it doesn"t get modified and remains intact. Reconsolidation: process of memory access that makes the memory prone to change. Ltp: the process by which the pyramidal cells can label memory pieces in cortical regions and therefore able to consolidate acquired memory (11:20) Synaptic connections related to a single episode. When a memory gets activated the connection gets strengthened. We have no idea how the molecular changes leads to the behavioural changes. Single pulse stimulation: electric pulse travels along the axon (an artificial ap), when it reaches the presynaptic terminal causing epsp (identical everytime).
