Visual processing pathways
Ungerleider et al., 1998
Suzuki and Amaral, 1994
Organization and strength of cortical inputsto the hippocampus
VanRullen, 2003
Hierarchical organization of the ventral visual stream
Schematic representation of the ventral visual pathway
Rousselet et al., 2004
Distributed semantic model
Patterson et al., 2007
Semantic hub model
Patterson et al., 2007
Patterson et al., 2007
- stroke- Herpes simplex virus encephalitis- Alzheimer’s disease- fronto-temporal dementia (semantic variant)
Semantic dementia (SD)
Patterson et al., 2007
Patterson et al., 2007
Patterson et al., 2007
Differences between semantic dementia and Alzheimer’s disease inmeasures of semantic memory
1 minute to list as many examples of a semantic category as they can
Pyramids and Palm Trees test of semantic association
Patterson et al., 2007
Differences between semantic dementia and Alzheimer’s disease inmeasures of brain hypometabolism regions
(18F)fluoro‑2- deoxy‑D -glucose positron emission tomography (FDG-PET)
Magnetoencephalography (MEG)
Positron emission tomography (PET)
Functional MRI (fMRI)
Voxel-based morphometry(T1‑weighted MRI)
Rostral temporal lobes are ‘hard-to-get’
“To paraphrase a recently-departedUnited States Secretary of Defense,
Hub model: ATL regions as beingcrucial for semantic processing, or …
we do not believe that the seeming absence of evidence constitutes,in this case, evidence of absence.“
