Corollary discharge across the animal kingdom
Our movements can hinder our ability to sense the world. Movements can induce sensory
input (for example, when you hit something) that is indistinguishable from the input that is …

Brain circuits for the internal monitoring of movements
MA Sommer, RH Wurtz - Annu. Rev. Neurosci., 2008 - annualreviews.org
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 …

Eye fields in the frontal lobes of primates
EJ Tehovnik, MA Sommer, IH Chou, WM Slocum… - Brain Research …, 2000 - Elsevier
Two eye fields have been identified in the frontal lobes of primates: one is situated dorsomedially
within the frontal cortex and will be referred to as the eye field within the dorsomedial …

A pathway in primate brain for internal monitoring of movements
MA Sommer, RH Wurtz - science, 2002 - science.org
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 …

Influence of the thalamus on spatial visual processing in frontal cortex
MA Sommer, RH Wurtz - Nature, 2006 - nature.com
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 …

Composition and topographic organization of signals sent from the frontal eye field to the superior colliculus
MA Sommer, RH Wurtz - Journal of neurophysiology, 2000 - journals.physiology.org
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. …

What the brain stem tells the frontal cortex. II. Role of the SC-MD-FEF pathway in corollary discharge
MA Sommer, RH Wurtz - Journal of neurophysiology, 2004 - journals.physiology.org
One way we keep track of our movements is by monitoring corollary discharges or internal

The role of the thalamus in motor control
MA Sommer - Current opinion in neurobiology, 2003 - Elsevier
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 …

Reversible inactivation of macaque frontal eye field
MA Sommer, EJ Tehovnik - Experimental Brain Research, 1997 - Springer
The macaque frontal eye field (FEF) is involved in the generation of saccadic eye movements
and fixations. To better understand the role of the FEF, we reversibly inactivated a portion …
