PSYC 273 Study Guide - Final Guide: Anterograde Amnesia, Neurofibrillary Tangle, Basal Ganglia
Chapter 13- Memory
• Amnesia
o Anterograde
▪ Inability to form new memories
o Retrograde
▪ Loss of memories before onset of amnesia- not uncommon after trauma
• H.M.
o Severe anterograde amnesia

o Had a surgery to help with epilepsy, but took out the hippocampus causing this
memory loss
• Categories of memory
o Declarative
▪ What

▪ Brain regions
• Medial temporal lobe
• Hippocampus
• Dorsomedial thalamus
• Mammillary bodies
o Non-declarative
▪ How
▪ Shown by performance
▪ Basal Ganglia
• Alzheier’s
o Dementia: a drastic failure of cognitive ability, including memory failure and
disorientation
o Alzheier’s is a for of deetia that appears efore age - not just normal
wear and tear due to old age
▪ Works backwards: hard to remember current things, but can remember
childhood things
▪ Amyloid plaques (protein build up) and neurofibrillary tangles (abnormal
whorls of tau)
▪ 1 in 9 over 65
• Brain regions and memory
o Left frontal cortex
▪ Conceptual (language; word meaning) priming
▪ Not hearig the rest of the setee eause you’re laughig at
something earlier in the sentence
o Cerebellum
▪ Associative learning (classical conditioning)
