Document Summary

Direct: projection to temporal cortex to retrieve memory. Indirect: sends info to neocortex (temporal) via thalamus and parahippocampal areas. When you first experience something, info will go to neocortex (temporal) Sends indirectly via parahippocampal areas or via thalamus. Lesion any part of this extended network memory deficits (interconnected) + effect all other networks. Semantic memory models : activate many parts of brain; distributed network of areas that contribute to semantic memory. Distribute-only view: semantic processing is supported by distributed network of modality specific regions; interactions between all those areas that combine and integrate information are necessary to access semantic. Distributed-plus-hub view : also relies on distributed network of modality specific regions; i. Key difference contains a amodal hub in anterior temporal cortex through which modality specific regions communicate. Evidence in semantic dementia from lesion to anterior temporal lobe. Cells in semantic memory temporal lobe neurons (discovered via electrode implantation of epilepsy patients)
