Document Summary
The brain: during embryonic develop, regulated gene expression and signal transaction initiates synapse develop on the 1 hand vs. neuron and synapse, death on the other, helping to shape the ns; est. connections networks for life and the overall cns, neuronal plasticity, brain is dynamic/changeable: connections btwn neurons can be modified, most remolding occurs @ synapses, changes are activity dependent. ) leads to inability to distribute new memories to ltm while retention of old memories ok: alzheimer"s = loss of stm, transfer from stm to ltm (encoding) forms a sustained memory which is strengthened by association with already retained memories, long term potential, activity dependent, resukts in stable increase in size of post synaptic potentials at synapse, learner needs to be active and use info, use of info is a sorting process so only important info is kept, ltp/memory formation facilitated thru, meaningful associations that aid in memory formation.
