    • 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 ...

    • Spectroscopic measurement of cortical nitric oxide release induced by ascending activation 

      Espinosa, J.; Cudeiro, Javier; Mariño Alfonso, Xurxo (Elsevier, 2014-11-25)
      [Abstract] The transition from sleep to the awake state is regulated by the activation of subcortical nuclei of the brainstem (BS) and basal forebrain (BF), releasing acetylcholine and glutamate throughout the cortex and ...

    • Synaptic Integration by V1 Neurons Depends on Location Within the Orientation Map 

      Schummers, James; Mariño Alfonso, Xurxo; Sur, Mriganka (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 ...

    • The operating regime of local computations in primary visual cortex 

      Stimberg, Marcel; Wimmer, Klaus; Martin, Robert; Schwabe, Lars; Mariño Alfonso, Xurxo; Schummers, James; Lyon, David C.; Sur, Mriganka; Obermayer, Klaus (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 ...

    • 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. ...
