We investigated the role of prefrontal cortex (PFC) in local contextual processing using a combined event-related potentials and lesion approach. Local context was defined as the occurrence of a short predictive series of visual stimuli occurring before delivery of a target event. Targets were preceded by either randomized sequences of standards…

Mammillary body atrophy is present in a number of neurological conditions and recent clinical findings highlight the importance of these nuclei for memory. While most accounts of diencephalic amnesia emphasize the functional importance of the hippocampal projections to the mammillary bodies, the present study tested the importance of the other…

Broca's area has been considered, for over a century, as the brain centre responsible for speech production. Modern neuroimaging and neuropsychological evidence have suggested a wider functional role is played by this area. In addition to the evidence that it is involved in syntactical analysis, mathematical calculation and music processing, it…
