Document Summary
What is memory: memory: the nervous system"s capacity to retain and retrieve skills and knowledge. Reconsolidation of memories: reconsolidation: neural processes involved when memories are recalled and then stored again for retrieval. In hebb"s interpretation, memories are stored in multiple regions of the brain: linked through memory circuits, multiple brain regions have been implicated in memory, hippocampus, prefrontal cortex, temporal lobes, cerebellum, amygdala, the brain structures involved in perception. Long-term potentiation: long-term potentiation (ltp): strengthening of a synaptic connection, making the postsynaptic neurons more easily activated by presynaptic neurons. Epigenetics of memory: epigenetic mechanisms control how dna is expressed, one such epigenetic mechanism involves a class of enzymes called hdac, which inhibit gene expression. Memory is distributed throughout the brain: equipotentiality: the idea that memory is distributed throughout the brain rather than confined to any specific location. In 1953, doctors took a radical surgical approach to quiet the seizures of henry molaison, a. k. a.
