Blood Oxygenation Level Dependent functional MRI (BOLD fMRI) during electrical paw stimulation has been widely used in studies aimed at the understanding of the somatosensory network in rats. However, despite the well-established anatomical connections between cortical and subcortical structures of the sensorimotor system, most of these functional studies have been concentrated on the cortical ...

This study aims at understanding the effect of multiple stimulations of a human optic nerve. Phosphenes (visual sensations) were obtained by electrical stimulation of a four contacts spiral cuff electrode previously implanted around the right optic nerve of a completely blind retinitis pigmentosa patient. When a stimulation was made through several contacts or repeated, the patient perceived se...
