Stochastic resonance in human electroencephalographic activity elicited by mechanical tactile stimuliE Manjarrez
Instituto de Fisiologia, Benemerita Universidad Autonoma de Puebla, 14 Sur 6301, Col San Manuel Apartado Postal 406, Puebla, Pue CP 72570, Mexico
Neurosci Lett 324:213-6. 2002..To our knowledge, this is the first documented evidence that such remarkable phenomenon embodies electrical processes of the human brain. Such behavior might explain related findings described in psychophysical studies...
Amplitude of somatosensory cortical evoked potentials is correlated with spontaneous activity of spinal neurones in the catE Manjarrez

Neurosci Lett 323:187-90. 2002..This observation suggests that transmission of cutaneous sensory information in ascending pathways could be facilitated when dorsal horn spinal neurones are active...
Cortical neuronal ensembles driven by dorsal horn spinal neurones with spontaneous activity in the catE Manjarrez
Instituto de Fisiologia, Benemerita Universidad Autonoma de Puebla, 14 Sur 6301 Col San Manuel, Apartado Postal 406, C P 72570, Pue, Puebla, Mexico
Neurosci Lett 318:145-8. 2002..This suggests very strongly that spontaneous neuronal activity in somatosensory regions of the brain is generated not only by ongoing activity of neurones located at supraspinal sites, but also by ongoing activity of spinal neurones...
