PSY 381 Lecture Notes - Lecture 15: Aplysia, Dentate Gyrus, Long-Term Potentiation
Document Summary
Non-declarative memory can be tested readily in animals. Short definition of declarative memory is that things you know that you can show by doing. Episodic memory and semantic memory are both declarative. A buffer that holds memories available for ready access during the performance of a task is working memory. Autobiographic and semantic memories are stored in different locations in the brain. The hippocampus of london cab drivers has been found to be enlarged as a result of spatial map learning compared to non-cab drivers. The sea slug aplysia shows a form of long-term learning that depends on modified synaptic activity. Donald hebb proposed in 1949 that when a presynaptic neuron repeatedly activates a postsynaptic neuron the strengthened connection between them constitutes learning. One form of long term potentiation occurring in hippocampal synapses involves. Nmda and ampa receptors in the same synapse.
