Document Summary
Hm & the anatomy & neurobiology of memory. Principal extra-temporal connections to the mtl: 3 regions of extra-temporal brain involved in memory, papez"s circuit, frontal lobes, diencephalon. Impairment of new fear learning: comprises of: maxillary bodies; fornix; anterior thalamic nuclei (atn); cingulate gyrus; hippocampus, general view: lesions to components result in declarative memory impairment, poor relational memory / encoding. Impairment most reliable when hippocampus / atn lesioned. Frontal lobes: motor programming, motor & premotor cortices (posterior fl, cognitive control processes, e. g. prob solving, planning, monitoring, self-correction, prefrontal cortex (anterior fl, & memory. Involved in development & implementing strategies for appropriate memory encoding & retrieval. Impairment in remembering contextual details: e. g. info source, chronological order of mems (dlpf, confabulation: production of statements involving bizarre memory distortions. & hippocampus: dense amnesic syndrome associated, cases with medio dorsal nucleus (mdn) and/or internal medullary.
