Cortical modulation of dorsal column nuclei: a computational study
(Springer, 2006-04-22)
[Abstract] We present a computational study aimed at exploring the sensorimotor cortex modulation of the behaviour of dorsal column nuclei, specifically the impact of synaptic parameters, during both sleep and waking ...
Changes in Visual Responses in the Feline dLGN: Selective Thalamic Suppression Induced by Transcranial Magnetic Stimulation of V1
(Oxford University Press, 2006-08-14)
[Abstract] Transcranial magnetic stimulation (TMS) of the cortex can modify activity noninvasively and produce either excitatory or inhibitory effects, depending on stimulus parameters. Here we demonstrate controlled ...
Lemniscal recurrent and transcortical influences on cuneate neurons
(Elsevier, 2000)
[Abstract] Intracellular recordings were obtained from cuneate neurons of chloralose-anesthetized, paralysed cats to study the synaptic responses induced by electrical stimulation of the contralateral medial lemniscus. ...
The operating regime of local computations in primary visual cortex
(Oxford University Press, 2009-02-16)
[Abstract] In V1, local circuitry depends on the position in the orientation map: close to pinwheel centers, recurrent inputs show variable orientation preferences; within iso-orientation domains, inputs are relatively ...
Invariant computations in local cortical networks with balanced excitation and inhibition
(Nature, 2005-06-23)
[Abstract] Cortical computations critically involve local neuronal circuits. The computations are often invariant across a cortical area yet are carried out by networks that can vary widely within an area according to its ...
Local networks in visual cortex and their influence on neuronal responses and dynamics
(Elsevier, 2005-11-07)
[Abstract] Networks of neurons in the cerebral cortex generate complex outputs that are not simply predicted by their inputs. These emergent responses underlie the function of the cortex. Understanding how cortical networks ...
La corteza cerebral modula la transmisión cutánea a través de los núcleos de los cordones posteriores
(J.V. Sánchez Andrés, 2001)
The mechanisms used by the cerebral cortex to modulate the cutaneous information at prethalamic level
have been scarcely studied. This article reviews experimental evidence leading to a better understanding of this issue ...
Synaptic Integration by V1 Neurons Depends on Location Within the Orientation Map
(Elsevier/Cell Press, 2002)
[Abstract] Neurons in the primary visual cortex (V1) are organized
into an orientation map consisting of orientation domains arranged radially around “pinwheel centers” at
which the representations of all orientations ...
A realistic computational model of the local circuitry of the cuneate nucleus
(Springer, 2001)
Intracellular recordings obtained under cutaneous and lemniscal
stimulation show that the afferent fibers can establish excitatory
and inhibitory synaptic connections with cuneothalamic neurons [5]. In
addition, distinct ...
Nitric oxide-mediated cortical activation: a diffuse wake-up system
(Society of Neuroscience, 2003)
Nitric oxide (NO) has been implicated in some of the central pathways engaged in the regulation of the sleep–wake cycle. The existence of
nitric oxide synthase (NOS) in the cholinergic basal forebrain (BF) cells projecting ...
