Document Summary
The modulation of memory and synaptic plasticity or how to make. Memory involves two components the storing of information and the ability to recall that information. When new experiences are stored in the brain there is a change in the brain that mediates information encoding. This is called synaptic plasticity new information changes the synaptic connections. Finding is consistent with the hypothesis: look at brain imaging study to look at possible mechanisms behind above finding. Amygdala is associated with emotionally charged stimuli. If we use animals we have to change the experimental approach. Need something that shows emotional responsiveness, has a similar brain structure, can be easily manipulated: pick a design. There can be two in this case. This takes several trials to make sure that they have learned the task. Once the rat has done a couple of trials they will go immediately to the quadrant with the platform. To avoid reinforcement the researcher will remove the platform.
