A Computational Model of Cuneothalamic Projection Neurons
Sánchez Vila, Eduardo; Barro Ameneiro, Senén; Mariño Alfonso, Xurxo; Canedo Lamas, Antonio (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 ... -
A realistic computational model of the local circuitry of the cuneate nucleus
Sánchez Vila, Eduardo; Barro Ameneiro, Senén; Mariño Alfonso, Xurxo; Canedo Lamas, Antonio (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 ... -
La corteza cerebral modula la transmisión cutánea a través de los núcleos de los cordones posteriores
Mariño Alfonso, Xurxo; Aguilar Fernández, Jaime; Soto, C.; Canedo Lamas, Antonio (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 ... -
Cortical modulation of dorsal column nuclei: a computational study
Sánchez Vila, Eduardo; Barro Ameneiro, Senén; Mariño Alfonso, Xurxo; Canedo Lamas, Antonio (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 ... -
Cortico-subcortical synchronization in the chloralose-anesthetized cat
Mariño Alfonso, Xurxo; Aguilar Fernández, Jaime; Canedo Lamas, Antonio (Elsevier, 1999-07)[Abstract] The spontaneous and paroxysmal cerebral cortical synchronized activity was used as reference to study the cortical impact exerted on subcortical neurons. The sensorimotor cortical synchronized activity spread ... -
Coupled slow and delta oscillations between cuneothalamic and thalamocortical neurons in the chloralose anesthetized cat
Mariño Alfonso, Xurxo; Martínez Otero, Luis Miguel; Canedo Lamas, Antonio (Elsevier, 1996)Simultaneous recordings were obtained from cuneothalamic (extracellular) and thalamocortical (intracellular) cells in chloralose anesthetized cats. It was found that cuneothalamic neurons present slow rhythmicity (0.1–1 ... -
Coupled slow and delta oscillations between cuneothalamic and thalamocortical neurons in the chloralose anesthetized cat
Mariño Alfonso, Xurxo; Martínez, Luis; Canedo Lamas, Antonio (Elsevier, 1996)[Abstract] Simultaneous recordings were obtained from cuneothalamic (extracellular) and thalamocortical (intracellular) cells in chloralose anesthetized cats. It was found that cuneothalamic neurons present slow rhythmicity ... -
Intracuneate mechanisms underlying primary afferent cutaneous processing in anaesthetized cats
Soto, C.; Aguilar, Juan; Martín-Cora, Francisco; Rivadulla, Casto; Canedo Lamas, Antonio (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 ... -
Lemniscal recurrent and transcortical influences on cuneate neurons
Canedo Lamas, Antonio; Mariño Alfonso, Xurxo; Aguilar Fernández, Jaime (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. ... -
Modelling the circuitry of the cuneate nucleus
Sánchez Vila, Eduardo; Barro Ameneiro, Senén; Mariño Alfonso, Xurxo; Canedo Lamas, Antonio; Vázquez Muñíz, Pablo José (Springer, 1999)Experimental data recorded in cat "in vivo" offer a new picture of the cuneate nucleus. Clasically definied as a simple relay station, the cuneate nucleus is currently seen as a fundamental stage in somatosensory information ... -
Sensorimotor cortical influences on cuneate nucleus rhythmic activity in the anesthetized cat
Mariño Alfonso, Xurxo; Canedo Lamas, Antonio; Aguilar Fernández, Jaime (Elsevier, 1999)[Abstract] This work aimed to study whether the sensorimotor cerebral cortex spreads down its rhythmic patterns of activity to the dorsal column nuclei. Extracellular and intracellular recordings were obtained from the ... -
Sleep and wakefulness in the cuneate nucleus: a computational study
Sánchez Vila, Eduardo; Barro Ameneiro, Senén; Mariño Alfonso, Xurxo; Canedo Lamas, Antonio (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
Aguilar, Juan; Soto, C.; Rivadulla, Casto; Canedo Lamas, Antonio (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
Sánchez Vila, Eduardo; Aguilar Fernández, Jaime; Rivadulla, Casto; Canedo Lamas, Antonio (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 ... -
Tonic and bursting activity in the cuneate nucleus of the chloralose-anesthetized cat
Canedo Lamas, Antonio; Martínez Otero, Luis Miguel; Mariño Alfonso, Xurxo (Elsevier, 1998)[Abstract] Whole-cell recordings were obtained from cuneate neurons in anesthetized, paralysed cats. Stimulation of the contralateral medial lemniscus permitted us to separate projection cells from presumed interneurons. ...
