Combined optical and electrical stimulation of neural tissue in vivo.
Low-intensity, pulsed infrared light provides a novel nerve stimulation modality that avoids the limitations of traditional electrical methods such as necessity of contact, presence of a stimulation artifact, and relatively poor spatial precision. Infrared neural stimulation (INS) is, however, limited by a 2:1 ratio of threshold radiant exposures for damage to that for stimulation. We have show...
متن کاملIntegrated device for optical stimulation and spatiotemporal electrical recording of neural activity in light-sensitized brain tissue.
Neural stimulation with high spatial and temporal precision is desirable both for studying the real-time dynamics of neural networks and for prospective clinical treatment of neurological diseases. Optical stimulation of genetically targeted neurons expressing the light sensitive channel protein Channelrhodopsin (ChR2) has recently been reported as a means for millisecond temporal control of ne...
متن کاملFabrication of Neural Probes for Simultaneous in Vivo Optical Stimulation and Electrical Recording in the Brain
Visual awareness, using a number of perceptual paradigms such as binocular rivalry and visual detection, has been studied for decades. Most researches focused on how activation of brain components, in particular, the cortex changes in line with the organism’s level of awareness. However, little emphasis is put on the autonomic nervous system (ANS) in response to transitions to and from awarenes...
