Responses 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 کاملPms, Eeg, and Photic Stimulation
David Noton, PhD The Forest Institute ABSTRACT Two studies of premenstrual syndrome (PMS), EEG, and photic stimulation have recently been completed at the Royal Postgraduate Medical School, Hammersmith Hospital, London (UK). In a preliminary trial of photic stimulation as a treatment for PMS seventeen women with PMS were treated with a take-home flashing light device for 15 to 20 minutes per da...
متن کاملHuman visual cortical function during photic stimulation monitoring by means of near-infrared spectroscopy.
Near-infrared spectroscopy (NIRS) was used to monitor human visual cortical function during and after photic stimulation (PS) in five adult volunteers. Cerebral blood volume (CBV) increased on the occipital surface during PS, but NIRS parameters did not change on the frontal surface. The increase in CBV was caused by a rapid increase in oxyhemoglobin with but a small increase in deoxyhemoglobin...
متن کاملOptical imaging of epileptiform events in visual cortex in response to patterned photic stimulation.
In a subset of patients with epilepsy, patterned visual stimuli can trigger clinical seizures. The etiology of this phenomenon, and the complex interaction between functional architecture and epilepsy, were investigated in ferret visual cortex. Optical imaging of intrinsic signals was used to visualize maps of orientation, ocular dominance and spatial frequency. Acute interictal spike foci were...
متن کاملCortical Evoked Potentials by Photic Stimulation at Variousadaptation Levels of Retina in Man.
Monnier,l-3) Cobb,4,5) Ciganek,6,8) Balen and Henkes,9,10) Laue,11.12), Calvet, Contamin and Hirsch et al.13-15) have studied on photically evoked potentials of the visual cortex in man, and thus at the present time physiological and anatomical correlation of the evoked potential to the visual cortex is being elucidated step by step by the method of evoked potentials and other physiological met...
