sensory-short-working-long term memory
hippocampus (epilepsy, encephalitis, embolia), corpora mamillaria (Korsakoff), nc. basalis magnocellularis Meynerti (Alzheimer), amygdala, basal ganglia, cerebellum
amnesia retrograde x anterograde
mechanisms-short: Hebb, NMDA, LTP, LTD
mechanisms-long: RNA, sprouting, proteinmemory
Hebb synapses: synapses that are strengthened due to the coincidence of pre-synaptic neuro- transmitter release and postsynaptic firing
Imprinting stored in memory
Imprinting is a form of learning closely associated with innate behaviour. Konrad Lorenz conducted an experiment with Greylag geese
Insight learning stored in memory = The ability of animals to perform appropriate behaviours on the first attempt in situations with which they have no prior experience.
Insight learning is best developed in primates. A chimpanzee placed in an area where a banana is hung too high to reach, but where boxes are scattered about, will "size" up the situation, stack the boxes, climb up and retrieve the banana.
Example: Niko Tinbergen noticed male three-spined stickleback fish responded aggressively to red trucks passing by their tank.
Fixed-Action Pattern: Male sticklebacks attack other males that enter their territories.
Sign stimulus: The red belly of the invading male. Sticklebacks attacked nonfish-like models with red on the ventral surface.
