The superior colliculus, or tectum in the case of non-mammalian vertebrates, is a part of the
brain that registers events in the surrounding space, often through vision and hearing, but …

The study of decision making spans such varied fields as neuroscience, psychology,
economics, statistics, political science, and computer science. Despite this diversity of …

The anti-saccade task has emerged as an important task for investigating the flexible control
that we have over behaviour. In this task, participants must suppress the reflexive urge to …

More than one third of the human brain is devoted to the processes of seeing-vision is after
all the main way in which we gather information about the world. But human vision is a …

The mammalian superior colliculus (SC) and its nonmammalian homolog, the optic tectum,
constitute a major node in processing sensory information, incorporating cognitive factors …

Decision making has recently emerged as a central theme in neurophysiological studies of
cognition, and experimental and computational work has led to the proposal of a cortical …

The syndrome of contralesional neglect reflects a lateralized disruption of spatial attention.
In the human, the left hemisphere shifts attention predominantly in the contralateral …

Ocular fixation is a dynamic process that is actively controlled by many of the same brain
structures involved in the control of eye movements, including the superior colliculus …

We measured saccadic eye movements in 168 normal human subjects, ranging in age from
5 to 79 years, to determine age-related changes in saccadic task performance. Subjects …

The ability to suppress reflexive responses in favor of voluntary motor acts is crucial for
everyday life. Both abilities can be tested with an oculomotor task, the antisaccade task. This …
