Spatial and temporal scales of neuronal correlation in visual area V4.
(J Neurosci, 2013-03-20)
The spiking activity of nearby cortical neurons is correlated on both short and long time scales. Understanding this shared variability in firing patterns is critical for appreciating the representation of sensory stimuli ...
Frontal eye field neurons assess visual stability across saccades.
(J Neurosci, 2012-02-22)
The image on the retina may move because the eyes move, or because something in the visual scene moves. The brain is not fooled by this ambiguity. Even as we make saccades, we are able to detect whether visual objects remain ...
Auditory signals evolve from hybrid- to eye-centered coordinates in the primate superior colliculus.
(Journal of neurophysiology, 2012-07)
Visual and auditory spatial signals initially arise in different reference frames. It has been postulated that auditory signals are translated from a head-centered to an eye-centered frame of reference compatible with the ...
Neuronal correlates of visual time perception at brief timescales.
(Proc Natl Acad Sci U S A, 2013-01-22)
Successful interaction with the world depends on accurate perception of the timing of external events. Neurons at early stages of the primate visual system represent time-varying stimuli with high precision. However, it ...
Metacognition in monkeys during an oculomotor task.
(J Exp Psychol Learn Mem Cogn, 2011-03)
This study investigated whether rhesus monkeys show evidence of metacognition in a reduced, visual oculomotor task that is particularly suitable for use in fMRI and electrophysiology. The 2-stage task involved punctate visual ...
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 ...
