| Term | Definition |
|---|---|
| anterograde amnesia | impairment in forming new memories |
| retrograde amnesia | inability to remember events prior to impairment |
| consolidation | process in which brain forms a (sorta) permanent physical representation of a memory |
| retreival | process of accessing stored memories-act of remembering |
| place cells | increase rate of firing when individual is in a specific location in the environment, found in hippocampus |
| declarative memory | involves learning that results in memories of facts, ppl, and events a person can verbalize/declare |
| nondeclarative memory | memories for behaviors from procedural/skills learning, emotional learning, and s-r conditioning |
| working memory | provides a temporary register for info while it's being used. |
| Hebb rule | if an axon of a presynaptic neuron is active while the postsynaptic neuron is firing, the synapse between them will be strengthened |
| LTP | persistent strengthening of synapses from simultaneous activation of presynaptic and postsynaptic neurons |
| LTD | decrease in strength of synapses when stimulation of presynaptic neurons is insufficient to activate the postsynaptic neuron. Modifies mems and clears old mems for new info |
| associative LTP | when weak and strong synapses on same postsynaptic neuron are active simultaneously, the weak one will be potentiated. Basis of CC. |
| dendritic spines | outgrowths from dendrites that partially bridge the synaptic cleft and make synapses more sensitive |
| dementia | substantial loss of memory and other cog abilities, usually in elderly |
| Alzheimer's | most common kind of dementia, characterized by progressive brain deterioration and impaired mem/other cog abilities |
| plaques | clumps of amyloid beta, a type of protein, that cluster among axon terminals and interfere with neural transmission |
| neurofibrillary tangles | formed by accumulation of tau protein inside neurons, associated with brain cell death |
| reserve hypothesis | ppl with greater cog/brain capacity can compensate for brain change due to aging, brain damage, or disorders like Alzheimer's. |
| spontaneous confabulation | fabricate stories/facts to make up for those missing from their memories. Common in those with Korsakoff. |
