Similar prevalence and magnitude of auditory-evoked and visually evoked activity in the frontal eye fields: implications for multisensory motor control.
(J Neurophysiol, 2016-06-01)
Saccadic eye movements can be elicited by more than one type of sensory stimulus. This implies substantial transformations of signals originating in different sense organs as they reach a common motor output pathway. In ...
Activity of neurons in monkey globus pallidus during oculomotor behavior compared with that in substantia nigra pars reticulata.
(J Neurophysiol, 2010-04)
The basal ganglia are a subcortical assembly of nuclei involved in many aspects of behavior. Three of the nuclei have high firing rates and inhibitory influences: the substantia nigra pars reticulata (SNr), globus pallidus ...
Visual continuity across saccades is Influenced by expectations
(Journal of Vision, 2016-02-09)
As we make saccades, the image on each retina is displaced, yet our visual perception is uninterrupted. This is commonly referred to as transsaccadic perceptual stability, but such a description is inadequate. Some visual ...
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 ...
RSA -- Respiratory Sinus Arrhythmia: A new measure of cardiac health

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 ...
Properties of decision-making tasks govern the tradeoff between model-based and model-free learning
<jats:title>Abstract</jats:title><jats:p>When decisions must be made between uncertain options, optimal behavior depends on accurate estimations of the likelihoods of different outcomes. The contextual factors that govern ...
Transduction of Craniofacial Motoneurons Following Intramuscular Injections of Canine Adenovirus Type-2 (CAV-2) in Rhesus Macaques
Reliable viral vector-mediated transgene expression in primate motoneurons would improve our ability to anatomically and physiologically interrogate motor systems. We therefore investigated the efficacy of replication defective, ...
Simultaneous transcranial magnetic stimulation and single-neuron recording in alert non-human primates.
(Nat Neurosci, 2014-08)
Transcranial magnetic stimulation (TMS) is a widely used, noninvasive method for stimulating nervous tissue, yet its mechanisms of effect are poorly understood. Here we report new methods for studying the influence of TMS ...
