The role of the thalamus in motor control.
(Curr Opin Neurobiol, 2003-12)
Two characteristics of the thalamus--its apparently simple relay function and its daunting multinuclear structure--have been customarily viewed as good reasons to study something else. Yet, now that many other brain regions ...
What the brain stem tells the frontal cortex. II. Role of the SC-MD-FEF pathway in corollary discharge.
(J Neurophysiol, 2004-03)
One way we keep track of our movements is by monitoring corollary discharges or internal copies of movement commands. This study tested a hypothesis that the pathway from superior colliculus (SC) to mediodorsal thalamus ...
Influence of the thalamus on spatial visual processing in frontal cortex.
Each of our movements activates our own sensory receptors, and therefore keeping track of self-movement is a necessary part of analysing sensory input. One way in which the brain keeps track of self-movement is by monitoring ...
Supplementary Eye Fields
(Encyclopedia of Neuroscience, 2009)
Visual perception and corollary discharge.
Perception depends not only on sensory input but also on the state of the brain receiving that input. A classic example is perception of a stable visual world in spite of the saccadic eye movements that shift the images ...
Brain circuits for the internal monitoring of movements.
(Annu Rev Neurosci, 2008)
Each movement we make activates our own sensory receptors, thus causing a problem for the brain: the spurious, movement-related sensations must be discriminated from the sensory inputs that really matter, those representing ...
Frontal eye field neurons with spatial representations predicted by their subcortical input.
(J Neurosci, 2009-04-22)
The frontal eye field (FEF) is a cortical structure involved in cognitive aspects of eye movement control. Neurons in the FEF, as in most of cerebral cortex, primarily represent contralateral space. They fire for visual ...
Multielectrode evidence for spreading activity across the superior colliculus movement map.
(J Neurophysiol, 2000-07)
The monkey superior colliculus (SC) has maps for both visual input and movement output in the superficial and intermediate layers, respectively, and activity on these maps is generally related to visual stimuli only in one ...
Drivers from the deep: the contribution of collicular input to thalamocortical processing.
(Prog Brain Res, 2005)
A traditional view of the thalamus is that it is a relay station which receives sensory input and conveys this information to cortex. This sensory input determines most of the properties of first order thalamic neurons, ...
The frontal eye field as a prediction map.
(Prog Brain Res, 2008)
Predictive processes are widespread in the motor and sensory areas of the primate brain. They enable rapid computations despite processing delays and assist in resolving noisy, ambiguous input. Here we propose that the frontal ...
