The assignment of figure and ground for a given visual display can dramatically alter the shape that human observers perceive. For example, depending on the figure/ground assignment in the image shown here, one sees either a head-on view of a woman, or two profiles. Baylis and Driver report a neural correlate of this effect: neurons in inferior temporal cortex of behaving monkeys respond to components of visual shape only when they are perceived as figure rather than ground. Shape analysis thus seems to be intertwined with figure/ground segregation.

Figure and ground in the brain

Segregation of an image into figure and ground is an important step in visual processing. Two new papers show that responses in human and monkey brain areas known to be involved in shape perception depend critically on whether a region is perceived as figure or ground.

Protofibrils, the unifying toxic molecule of neurodegenerative disorders?

A newly identified Alzheimer's mutation leads to the suggestion that protofibril intermediates in amyloid plaque formation may be a crucial factor in pathogenicity.

Neuronal migration and the evolution of the human brain

A new study demonstrating a pathway for neuronal migration in humans, but not in monkeys, suggests that migration has a key role in the evolution of the brain, as well as its development.
