Intracortical Microstimulation Parameters Dictate the Amplitude and Latency of Evoked Responses
Brain Stimulation, 2016 Microstimulation of brain tissue plays a key role in a variety of sensory prosthetics, clinical therapies and research applications. However, the effects of stimulation parameters on the responses they evoke remain widely unknown.We aimed to investigate the contribution of each stimulation parameter to the response and identify interactions existing ...

Behavioral assessment of sensitivity to intracortical microstimulation of primate somatosensory cortex. [PDF]
Proc Natl Acad Sci U S A, 2015 Significance Electrical stimulation of sensory structures in the brain is a powerful tool to investigate neural circuits and may provide a means to restore sensation for patients for whom stimulation of the nerve is not an option. For both purposes, however, it is critical to understand how the design of the stimulation shapes the evoked ...

Optical imaging of cortical networks via intracortical microstimulation.
J Neurophysiol, 2013 Understanding cortical organization is key to understanding brain function. Distinct neural networks underlie the functional organization of the cerebral cortex; however, little is known about how different nodes in the cortical network interact during perceptual processing and motor behavior. To study cortical network function we examined whether the

Optimal interphase delay in biphasic current pulses facilitates neural circuit activation induced by microstimulation in the mouse visual cortex. [PDF]
Front NeurosciCathodic-first biphasic current pulses are commonly employed in intracortical microstimulation. Due to the intricate arrangement of axons, somata, and dendrites in the cerebral cortex, membrane polarizations induced by the cathodic and subsequent anodic ...
