Receptive Properties of Mouse Sensory Neurons Innervating Hairy Skin
Journal of Neurophysiology - Tập 78 Số 4 - Trang 1841-1850 - 1997
Martin Koltzenburg, Cheryl L. Stucky, Gary R. Lewin
Koltzenburg, Martin, Cheryl L. Stucky, and Gary R. Lewin. Receptive properties of mouse sensory neurons innervating hairy skin. J. Neurophysiol. 78: 1841–1850, 1997. Using an in vitro nerve skin preparation and controlled mechanical or thermal stimuli, we analyzed the receptive properties of 277 mechanosensitive single primary afferents with myelinated ( n = 251) or unmyelinated ( n = 26) ...... hiện toàn bộ
Chemosensitivity of fine afferents from rat skin in vitro
Journal of Neurophysiology - Tập 63 Số 4 - Trang 887-901 - 1990
E. Lang, A. I. Novak, Peter W. Reeh, H. O. Handwerker
1. Properties of sensory receptors with slowly conducting nerve fibers (less than 10 m/s) were studied using a rat skin-saphenous nerve in vitro preparation where receptive fields of identified single units can be isolated and superfused at the corium side with defined chemical solutions. 2. With mechanical search stimuli, 150 slowly adapting units were identified, 88% C-fibers, and the r...... hiện toàn bộ
Bullfrog dorsal root ganglion cells having tetrodotoxin-resistant spikes are endowed with nicotinic receptors
Journal of Neurophysiology - Tập 62 Số 3 - Trang 657-664 - 1989
Kenichi Morita, Yoshimi Katayama
1. Intracellular recordings were made from bullfrog dorsal root ganglion (DRG) neurons in vitro. They were divided into three types, As, Ar, and C, according to their conduction velocity and their sensitivity to tetrodotoxin [TTX (less than or equal to 1 microM)]; an As neuron had a fast conduction velocity (13-50 m/s, mean = 31 m/s, n = 73) and TTX-sensitive sodium soma spikes: an Ar neu...... hiện toàn bộ
Control of unitary activities in cerebellothalamic pathway during wakefulness and synchronized sleep.
Journal of Neurophysiology - Tập 34 Số 3 - Trang 389-413 - 1971
Mircea Steriade, V. Apostol, G. Oakson
Induction of NMDA and GABAAReceptor-Mediated Ca2+Oscillations With KCC2 mRNA Downregulation in Injured Facial Motoneurons
Journal of Neurophysiology - Tập 89 Số 3 - Trang 1353-1362 - 2003
Hiroki Toyoda, Koji Ohno, Junko Yamada, Masahiko Ikeda, Akihito Okabe, Kohji Sato, Kenji Hashimoto, Atsuo Fukuda
To clarify the changes that occur in γ-aminobutyric acid type A (GABAA) receptor-mediated effects and contribute to alterations in the network activities after neuronal injury, we studied intracellular Ca2+concentration ([Ca2+]i) dynamics in a rat facial-nerve-transection model. In facial motoneurons, an el...... hiện toàn bộ
Postnatal maturation of the GABAergic system in rat neocortex
Journal of Neurophysiology - Tập 65 Số 2 - Trang 247-263 - 1991
Heiko J. Luhmann, D. A. Prince
1. The postnatal maturation of intracortical inhibitory circuitry and the development of responses to applied gamma-aminobutyric acid (GABA) and baclofen were studied in pyramidal and nonpyramidal neurons from layers II and III of the rat primary somatosensory and primary visual cortex, in vitro. 2. Depolarizing spontaneous inhibitory postsynaptic potentials (IPSPs) could be recorded in a...... hiện toàn bộ
Alterations in NMDA Receptors in a Rat Model of Cortical Dysplasia
Journal of Neurophysiology - Tập 83 Số 1 - Trang 315-321 - 2000
R. Anthony DeFazio, John J. Hablitz
Recent studies have demonstrated an important role for the N-methyl-d-aspartate receptor (NMDAR) in epilepsy. NMDARs have also been shown to play a critical role in hyperexcitability associated with several animal models of human epilepsy. Using whole-cell voltage clamp recordings in brain slices, we studied evoked paroxysmal discharges in the freeze-lesion model of neocortical microgyria...... hiện toàn bộ
Unified theory regarding A/P and M/L balance in quiet stance
Journal of Neurophysiology - Tập 75 Số 6 - Trang 2334-2343 - 1996
David Winter, François Prince, James S. Frank, C. Powell, Karl Zabjek
1. Control of posture in quiet stance has been quantified by center of pressure (COP) changes in the anterior-posterior (A/P) and medial-lateral (M/L) directions from a single force platform. Recording from a single force platform, researchers are unable to recognize two separate mechanisms that become evident when two force platforms are used. Depending on the stance position taken, many...... hiện toàn bộ
Stiffness Control of Balance in Quiet Standing
Journal of Neurophysiology - Tập 80 Số 3 - Trang 1211-1221 - 1998
David Winter, Aftab E. Patla, François Prince, Milad G. Ishac, Krystyna Gielo‐Perczak
Winter, David A., Aftab E. Patla, Francois Prince, Milad Ishac, and Krystyna Gielo-Perczak. Stiffness control of balance in quiet standing. J. Neurophysiol. 80: 1211–1221, 1998. Our goal was to provide some insights into how the CNS controls and maintains an upright standing posture, which is an integral part of activities of daily living. Although researchers have used simple performance...... hiện toàn bộ
The organization of the human cerebral cortex estimated by intrinsic functional connectivity
Journal of Neurophysiology - Tập 106 Số 3 - Trang 1125-1165 - 2011
B.T. Thomas Yeo, Fenna M. Krienen, Jorge Sepulcre, Mert R. Sabuncu, Danial Lashkari, Marisa O. Hollinshead, Joshua L. Roffman, Jordan W. Smoller, Lilla Zöllei, Jonathan R. Polimeni, Bruce Fischl, Hesheng Liu, Randy L. Buckner
Information processing in the cerebral cortex involves interactions among distributed areas. Anatomical connectivity suggests that certain areas form local hierarchical relations such as within the visual system. Other connectivity patterns, particularly among association areas, suggest the presence of large-scale circuits without clear hierarchical relations. In this study the organizati...... hiện toàn bộ
