Two types of learning system Neocortex, which learns slowly, allows integration into complex knowledge structures. Hippocampal, which learns quickly, supports rapid one-trial learning It teaches neocortex its information during consolidation NEOCORTex: priming, implicit knowledge, procedural Hippocampus: DECLarative and explicit knowledge, recognition, etc. Korsokoff’s syndrome: damage to the diencephalons from alcohol abuse initiated vitamin deficiency. Areas affected: dorso-medial thalamic nucleus, mamillary bodies, MTL, frontal lobe. Similar to hippocampal damage but more complex What were the major symptoms of classifications of memory loss?? He had good digit span and spatial span (working memory). Was long term memory off? Declarative off? Procedural off?? Plasticity paradox : on the one hand—the brain has specific regions and structures for specific tasks (evidence from cases like Broca where damage and deficiencies were specific, cortical stimulation, functional neuro imaging, single cell recording, special
