A corollary discharge for perceptual stability
(PERCEPTION, 2006) -
A pathway in primate brain for internal monitoring of movements.
(Science, 2002-05-24)It is essential to keep track of the movements we make, and one way to do that is to monitor correlates, or corollary discharges, of neuronal movement commands. We hypothesized that a previously identified pathway from brainstem ... -
A screw microdrive for adjustable chronic unit recording in monkeys.
(J Neurosci Methods, 1998-06-01)A screw microdrive is described that attaches to the grid system used for recording single neurons from brains of awake behaving monkeys. Multiple screwdrives can be mounted on a grid over a single cranial opening. This ... -
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 ... -
Composition and topographic organization of signals sent from the frontal eye field to the superior colliculus.
(J Neurophysiol, 2000-04)The frontal eye field (FEF) and superior colliculus (SC) contribute to saccadic eye movement generation, and much of the FEF's oculomotor influence may be mediated through the SC. The present study examined the composition ... -
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, ... -
Frontal eye field neurons orthodromically activated from the superior colliculus.
(J Neurophysiol, 1998-12)Frontal eye field neurons orthodromically activated from the superior colliculus. J. Neurophysiol. 80: 3331-3333, 1998. Anatomical studies have shown that the frontal eye field (FEF) and superior colliculus (SC) of monkeys ... -
Frontal eye field sends delay activity related to movement, memory, and vision to the superior colliculus.
(J Neurophysiol, 2001-04)Many neurons within prefrontal cortex exhibit a tonic discharge between visual stimulation and motor response. This delay activity may contribute to movement, memory, and vision. We studied delay activity sent from the frontal ... -
Identifying corollary discharges for movement in the primate brain.
(Prog Brain Res, 2004)The brain keeps track of the movements it makes so as to process sensory input accurately and coordinate complex movements gracefully. In this chapter we review the brain's strategies for keeping track of fast, saccadic ... -
Influence of the thalamus on spatial visual processing in frontal cortex.
(Nature, 2006-11-16)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 ... -
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 ... -
Signal transformations from cerebral cortex to superior colliculus for the generation of saccades.
(Vision Res, 2001)The ability of primates to make rapid and accurate saccadic eye movements for exploring the natural world is based on a neuronal system in the brain that has been studied extensively and is known to include multiple brain ... -
Single Neurons and Primate Behavior
(Methods in Mind, 2009) -
The Dialogue Between Cerebral Cortex and Superior Colliculus: Implications for Saccadic Target Selection and Corollary Discharge
(The Visual Neurosciences, 2003) -
The Dialogue between Cerebral Cortex and Superior Colliculus: Multiple Ascending Pathways for Corollary Discharge
(The New Visual Neurosciences, 2014) -
The frontal eye field sends predictively remapped visual signals to the superior colliculus
(Journal of Vision, 2003-12-01)We perceive a stable visual world even though saccades often move our retinas. One way the brain may achieve a stable visual percept is through predictive remapping of visual receptive fields: just before a saccade, the ... -
The Superior Colliculus and the Cognitive Control of Movement
(The New Cognitive Neurosciences, 2000) -
Visual perception and corollary discharge.
(Perception, 2008)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 ... -
What the brain stem tells the frontal cortex. I. Oculomotor signals sent from superior colliculus to frontal eye field via mediodorsal thalamus.
(J Neurophysiol, 2004-03)Neuronal processing in cerebral cortex and signal transmission from cortex to brain stem have been studied extensively, but little is known about the numerous feedback pathways that ascend from brain stem to cortex. In this ...
