Hyperthermic Spreading Depressions in the Immature Rat Hippocampal Slice
Journal of Neurophysiology - Tập 84 Số 3 - Trang 1355-1360 - 2000
Jie Wu, Robert S. Fisher
Febrile seizures are the most common seizure type in children (6 mo to 5 yr). The pathophysiology of febrile seizures is unknown. Current genetic studies show that some febrile seizures result from channelopathies. We have performed electrophysiological experiments in in vitro hippocampal slices to test a novel hypothesis that a disordered regulation of ionic homeostasis underlies the gen...... hiện toàn bộ
Reorganization of the Raccoon Cuneate Nucleus After Peripheral Denervation
Journal of Neurophysiology - Tập 78 Số 6 - Trang 2924-2936 - 1997
D. D. Rasmusson, Stacey A. Northgrave
Rasmusson, Douglas D. and Stacey A. Northgrave. Reorganization of the raccoon cuneate nucleus after peripheral denervation. J. Neurophysiol. 78: 2924–2936, 1997. The effects of peripheral nerve transection on the cuneate nucleus were studied in anesthetized raccoons using extracellular, single-unit recordings. The somatotopic organization of the cuneate nucleus first was examined in intac...... hiện toàn bộ
Thalamic state control of cortical paired-pulse dynamics
Journal of Neurophysiology - Tập 117 Số 1 - Trang 163-177 - 2017
Clarissa J. Whitmire, Daniel C. Millard, Garrett B. Stanley
Sensory stimulation drives complex interactions across neural circuits as information is encoded and then transmitted from one brain region to the next. In the highly interconnected thalamocortical circuit, these complex interactions elicit repeatable neural dynamics in response to temporal patterns of stimuli that provide insight into the circuit properties that generated them. Here, usi...... hiện toàn bộ
Effect of passive eye position changes on retinogeniculate transmission in the cat
Journal of Neurophysiology - Tập 63 Số 3 - Trang 502-522 - 1990
Ratnesh Lal, M. J. Friedlander
1. Extracellular recordings were made from single neurons in layer A of the left dorsal lateral geniculate nucleus (LGNd) of anesthetized and paralyzed adult cats. Responses to retinotopically identical visual stimuli (presented through the right eye) were recorded at several positions of the left eye in its orbit. Visual stimuli consisted of drifting sinusoidal gratings of optimal tempor...... hiện toàn bộ
Somatosensory Input to Auditory Association Cortex in the Macaque Monkey
Journal of Neurophysiology - Tập 85 Số 3 - Trang 1322-1327 - 2001
Charles E. Schroeder, Robert W. Lindsley, Colleen M. Specht, Alvin Marcovici, John F. Smiley, Daniel C. Javitt
We investigated the convergence of somatosensory and auditory inputs in within subregions of macaque auditory cortex. Laminar current source density and multiunit activity profiles were sampled with linear array multielectrodes during penetrations of the posterior superior temporal plane in three macaque monkeys. At each recording site, auditory responses to binaural clicks, pure tones, a...... hiện toàn bộ
Impact of unilateral and bilateral impairments on bimanual force production following stroke
Journal of Neurophysiology - Tập 130 Số 3 - Trang 608-618 - 2023
Hien Nguyen, Thanh Quoc Phan, Reza Shadmehr, Sang Wook Lee
We studied how unilateral and bilateral impairments in stroke survivors affect their bimanual task performance. Unilateral impairments of the more-impaired limb, both weakness and loss of directional control, mainly contribute to bimanual asymmetry, but stroke survivors generally produce higher force with their more-impaired limb than their relative capacity. Bilateral force coordination ...... hiện toàn bộ
Influence of Predictive Information on Responses of Tonically Active Neurons in the Monkey Striatum
Journal of Neurophysiology - Tập 80 Số 6 - Trang 3341-3344 - 1998
Paul Apicella, Sabrina Ravel, Pierangelo Sardo, Eric Legallet
Apicella, Paul, Sabrina Ravel, Pierangelo Sardo, and Eric Legallet. Influence of predictive information on responses of tonically active neurons in the monkey striatum. J. Neurophysiol. 80: 3341–3344, 1998. We investigated how the expectation of a signal of behavioral significance influences the activity of tonically active neurons in the striatum of two monkeys performing a simple reacti...... hiện toàn bộ
Intravenous Morphine Increases Release of Nitric Oxide From Spinal Cord by an α-Adrenergic and Cholinergic Mechanism
Journal of Neurophysiology - Tập 78 Số 4 - Trang 2072-2078 - 1997
Zemin Xu, Chuanyao Tong, Hui‐Lin Pan, S. Cerda, James C. Eisenach
Xu, Zemin, Chuanyao Tong, Hui-Lin Pan, Sergio E. Cerda, and James C. Eisenach. Intravenous morphine increases release of nitric oxide from spinal cord by an α-adrenergic and cholinergic mechanism. J. Neurophysiol. 78: 2072–2078, 1997. Systemic opioids produce analgesia in part by activating bulbospinal noradrenergic pathways. Spinally released norepinephrine (NE) has been suggested to pro...... hiện toàn bộ
Differential Modulation by Nicotine of Substantia Nigra Versus Ventral Tegmental Area Dopamine Neurons
Journal of Neurophysiology - Tập 98 Số 6 - Trang 3388-3396 - 2007
J. Russel Keath, Michael P. Iacoviello, Lindy E. Barrett, Huibert D. Mansvelder, Daniel S. McGehee
Midbrain dopamine (DA) neurons are found in two nuclei, the substantia nigra pars compacta (SNc) and ventral tegmental area (VTA). The SNc dopaminergic projections to the dorsal striatum are involved in voluntary movement and habit learning, whereas the VTA projections to the ventral striatum contribute to reward and motivation. Nicotine induces profound DA release from VTA dopamine neuro...... hiện toàn bộ
Neural correlates of motion processing through echolocation, source hearing, and vision in blind echolocation experts and sighted echolocation novices
Journal of Neurophysiology - Tập 111 Số 1 - Trang 112-127 - 2014
L. Thaler, Jennifer L. Milne, S. R. Arnott, Daniel Kish, Melvyn A. Goodale
We have shown in previous research (Thaler L, Arnott SR, Goodale MA. PLoS One 6: e20162, 2011) that motion processing through echolocation activates temporal-occipital cortex in blind echolocation experts. Here we investigated how neural substrates of echo-motion are related to neural substrates of auditory source-motion and visual-motion. Three blind echolocation experts and twelve sighte...... hiện toàn bộ
