Perisylvian language networks of the human brain
The anatomical findings are relevant to the evolution of language, provide a framework for Lichtheim's symptom‐based neurological model of aphasia, and constrain, anatomically, contemporary connectionist accounts of language.
Diagnosis and management of dementia with Lewy bodies
The Dementia with Lewy Bodies (DLB) Consortium has refined its recommendations about the clinical and pathologic diagnosis of DLB, updating the previous report, which has been in widespread use for…

The results suggest that a major associative connection between the occipital and anterior temporal lobe is provided by a fibre bundle whose origin, course and termination are consistent with classical descriptions of the ILF in man and with monkey visual anatomy.
The rises and falls of disconnection syndromes.
The changing fortunes of disconnection theory is described, on the 40th anniversary of Geschwind's publication, and the general framework that evolved from it is adapted to encompass the entire spectrum of higher function disorders in neurology and psychiatry.
The Riddoch syndrome: insights into the neurobiology of conscious vision.
It is concluded that agnosopsia, gnosopsia and gnosanopsia are all manifestations of a single condition which the Riddoch syndrome, in deference to the British neurologist who, in 1917, first characterized the major aspect of this disability.
The parallel visual motion inputs into areas V1 and V5 of human cerebral cortex.
The technique of visually evoked EEG coupled to magnetoencephalography (MEG) is used to test the hypothesis that there are parallel pathways which lead to the striate (V1) and prestriate cortex in the human brain, and it is found that, if the moving stimulus has a speed of 22 degrees s-1, signals arrive in V5 before V1.
Cognitive decline in Parkinson disease
New genetic evidence indicates that in addition to the APOE*ε4 allele (an established risk factor for AD), GBA mutations and SCNA mutations and triplications are associated with cognitive decline in PD, whereas the findings are mixed for MAPT polymorphisms.
Cognitive effects of nicotine in humans: an fMRI study
The neural correlates of conscious vision.
The broad temporal and spatial distribution of activity argues against a unified, distributed fronto-parietal correlate of consciousness and suggests that correlates of consciousness are divided into primary and secondary network nodes, with early activity in the occipital lobe correlating with perception and later activity in downstream areas with secondary processes contingent on the outcome of earlier perceptual processing.
