Severe anterograde amnesia (Milner et al, 1968) 1 of 21 Hippocampal memories are consolidated into the neocortex and become hippocampal independent Marr, 1971 2 of 21 Episodic memory and the hippocampus Zola-Morgan et al 1987. – CA1 of hippocampus lesions lead to anterograde amnesia 3 of 21 Alzheimers patients and the MTL/episodic memory Hyman et al – Alzheimers patients show early signs of amnesia when they have their first lesions in the MTL. Also Weintraub et al, 2012 4 of 21 Episodic memory and the mamillary bodies Press et al – Korsakoff’s patients – damage to diencephalon and mammillary bodies have varied amnesia 5 of 21 Episodic memory and confabulation Burgess and Shallice – Frontal lobe damage leads to confabulated memories. 6 of 21 Episodic memory and impaired source memory Janowsky et al – frontal lobe damage leads to impaired source memory 7 of 21 Episodic memory and interference Shimamura - frontal lobe damage leads to stronger interference 8 of 21 Semantic Memory and Left Temporal Damage Warrington, 1975. LEFT temporal damage – visual agnosia. 9 of 21 Semantic Memory and Left MEDIAL Temporal Damage Warrington and Shallice, 1984. Left medial temporal damage – catergory-specific amodal agnosia. 10 of 21 Lateral temporal lobe areas and catergory specific deficits • Damasio, 1996 o Temporal pole – person naming o Left middle inferior – animal naming o Posterior inferior – tool naming 11 of 21 Semantic dementia Left anterior temporal atrophy is associated with semantic dementia. Hodges, 2001 12 of 21 Working memory and the lateral frontal lobes Milner, 1963. Patients with frontal lobe damage have difficulties maipulating information in working memory tasks 13 of 21 Workign memory and Age-related Frontal-Striatal decline working memory deficits (Gabrieli, 1996) 14 of 21 Working memory and lateral parietal lobes Lesions of Left Supramarginal / Inferior Parietal Cortex -> auditory-verbal maintenance deficit, eg. KF (Warrington & Shallice, 1969) 15 of 21 Working memory and the parietal cortex Lesion of Right Inferior Parietal Cortex -> visuospatial maintenance deficit, eg. ELD (Hanley et al., 1991) 16 of 21 Priming deficits right occipital lesions have no perceptual priming. Gabrielli et al, 1995 17 of 21 Proceedural memory deficits huntington's patients had impaired rotary pursuit, gabrielli, and serial reaction task, willingham and koroshetz 18 of 21 Conditioning and the cerebellum Delay conditioning is abolished in cerebellar lesions, daum et al 1993 19 of 21 Conditioning and the amygdala fear conditioning is impaired following amygdala resection - LeBar, 1995 20 of 21 SenseCam Study Berry et al, 2006. Events reviewed with sensecam more resistant to decline tan those rehearsed with a written diary 21 of 21
