Optimal interphase delay in biphasic current pulses facilitates neural circuit activation induced by microstimulation in the mouse visual cortex [PDF]
Frontiers in NeuroscienceCathodic-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 ...

Equalization for intracortical microstimulation artifact reduction [PDF]
2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013 We present a method for decreasing the duration of artifacts present during intra-cortical microstimulation (ICMS) recordings by using techniques developed for digital communications. We replace the traditional monophasic or biphasic current stimulation pulse with a patterned pulse stream produced by a Zero Forcing Equalizer (ZFE) filter after ...

High density nanowire electrodes for intracortical microstimulation [PDF]
2019 41st Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2019 High-density electrodes with the nano feature size greatly enhance resolution and specificity during intracortical microstimulation. In this viewpoint, we fabricated and developed high-density nanowire (NW) electrodes, ~ 2.45×109 / cm2 that could directly stimulate specific region of the cortex with low current amplitude in the range of 120-180 μA. The

Phase-Specific Microstimulation Differentially Modulates Beta Oscillations and Affects Behavior
Cell Reports, 2020 Summary: It is widely accepted that Beta-band oscillations play a role in sensorimotor behavior. To further explore this role, we developed a hybrid platform to combine neural operant conditioning and phase-specific intracortical microstimulation (ICMS).

Bioelectronic Medicine, 2022 Background Acquired brain injuries, such as stroke, are a major cause of long-term disability worldwide. Intracortical microstimulation (ICMS) can be used successfully to assist in guiding appropriate connections to restore lost sensorimotor integration.

Forelimb movements evoked by optogenetic stimulation of the macaque motor cortex
Nature Communications, 2020 Non-human primates are useful models for understanding the human brain but application of optogenetics to non-human primates is challenging. The authors used optogenetic intracortical microstimulation in the primary motor cortex of macaques to elicit ...

Muscle synergies evoked by microstimulation are preferentially encoded during behavior
Frontiers in Computational Neuroscience, 2014 Electrical microstimulation studies provide some of the most direct evidence for the neural representation of muscle synergies. These synergies, i.e. coordinated activations of groups of muscles, have been proposed as building blocks for the construction
