Cortical responses to local electrical stimulation of retina.
Extensive cortical excitation from punctiform photic stimuli has been difficult to interpret because of intraoptic diffusion of light. Direct electrical stimulation of the exposed retina was thus used in this attempt to determine the degree of spatial elaboration of stimuli in the retinocortical system. Multichannel CR0 recording from cortex and optic tract show two types of response in anesthe...
متن کاملResponses of primary somatosensory cortical neurons to controlled mechanical stimulation.
The results of psychophysical studies suggest that displacement velocity may contribute significantly to the sensation of subcortical somatosensory neurons. The cortical correlates of these phenomena, however, are not known. In the present study the responses of rapidly adapting (RA) neurons in the forelimb region of cat primary somatosensory cortex (SI) to controlled displacement of skin and h...
متن کاملEffect of locus ceruleus phasic electrical stimulation on responses of barrel cortical cells to controlled mechanical displacement in rats
Behavioral and electrophysiological evidences have shown that locus ceruleus (LC) is involved in different tasks including modulation of sensory processing and shift of attention. In the present study, single unit responses of barrel cortical cells was recorded following controlled mechanical displacement of the principal and peripheral vibrissae in adult rats (100 trials of 200 µm deflection f...
متن کامل(u) Evoked Cortical Responses to Electrical Stimulation of the Ischemic Retina
Loss of function in the retina due to ischemia has been successfully monitored by using electrical stimulation of the eye to evoke cortical responses. The earliest detection of loss of function due to decreased (or cessation of) blood flow in the retina yet achieved has used the average of 4-16 responses to electrical stimulation of the eye using external electrodes. Attempts to detect single r...
متن کاملPrimary auditory cortical responses to electrical stimulation of the thalamus.
Cochlear implant electrical stimulation of the auditory system to rehabilitate deafness has been remarkably successful. Its deployment requires both an intact auditory nerve and a suitably patent cochlear lumen. When disease renders prerequisite conditions impassable, such as in neurofibromatosis type II and cochlear obliterans, alternative treatment targets are considered. Electrical stimulati...
