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 ...
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. ...
Intracuneate mechanisms underlying primary afferent cutaneous processing in anaesthetized cats
(Wiley, 2004-06-02)
[Abstract] The cutaneous primary afferents from the upper trunk and forelimbs reach the medial cuneate nucleus in their way towards the cerebral cortex. The aim of this work was twofold: (i) to study the mechanisms used ...
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 ...
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 ...
A Computational Model of Cuneothalamic Projection Neurons
(Taylor and Francis, 2003)
[Abstract] The dorsal column nuclei, cuneatus and gracilis, play a fundamental role
in the processing and integration of somesthetic ascending information.
Intracellular and patch-clamp recordings obtained in cat in vivo ...
Sleep and wakefulness in the cuneate nucleus: a computational study
(Springer, 2003)
We present a computational study about the influence of the
sensorimotor cortex on the processing of the cuneate nucleus during sleep
as well as wakefulness. Realistic computational models were developed
supported by ...
The lemniscal–cuneate recurrent excitation is suppressed by strychnine and enhanced by GABAA antagonists in the anaesthetized cat
(Wiley, 2002-11-13)
[Abstract] In the somatosensory system, cuneolemniscal (CL) cells fire high frequency doublets of spikes facilitating the transmission of sensory information to diencephalic target cells. We studied how lemniscal feedback ...
The role of glyclinergic interneurons in the dorsal column nuclei
(Elsevier, 2004-03-12)
[Abstract] The aim of this paper is to provide new insights about the circuitry and the role of the dorsal column nuclei (DCN) in processing somatosensory information. The presence of glycinergic cells, a second type of ...
