PSYB64H3 Lecture Notes - Lecture 9: Anterograde Amnesia, Retrograde Amnesia, Karl Lashley
Document Summary
Psyb64 lecture 9 learning and memory : not responsible for: Classical conditioning in vertebrates pages 348 to 351. Biochemical factors in long term memory pages 366 to 368. You need to know ltp pages 358 to 361 only to the extent it is covered in lecture: learning. Often habituation occurs to unchanging, harmless stimuli as a means of focusing our attention on relevant stimuli: sensitization occurs when an exposure to a strong stimulus actually heightens an organism"s overall level of response to other environmental stimuli. Cs in absence of the ucs then the response is called a conditioned response (cr). Reduced activity at synapse between sensory and motor neurons. A stimulus gains the ability to influence more than one neural pathway neurotransmitter release. Sequential activation of sensory neurons by cs and ucs leads to greater structural changes in synapses from learning. Karl lashley observed the results of brain lesions on maze-learning. Trapped in the eternal now : introducing hm.
