Document Summary
Memory and learning: ltp (long term potentiation) A lasting increase in the strength of synaptic transmission. Stimulus sensory memory stortage encoding stm encoding ltm (retrieving memories from ltm activates ltp: neuronal development. Neuron death: neurons compete for survival those that reach their proper locations survive. Synapse elimination: a developing neuron forms too many synapses and its activity stabilizes some synapses and gets rid of others: lt vs. st memory. Stm: info is held for a short time and then released if not used. Ltm: activated when info is needed fetch it from ltm and bring it to stm. Involve storage of memory in cerebral cortex: stm: info is accessed via temporary links in hippocampus, ltm: info is connected in the cerebral cortex, neuronal plasticity. Nervous system"s ability to be remodeled (mostly at synapses) More activity connection is strengthened and you gain more (ex. Reinforce material activate ltp better storage of memory: organizers are tools for learning.
