- Sensorimotor Rhythm(also: SMR, Sensorimotor Cortical Rhythm)
- Oscillatory electrical brain activity recorded over the sensorimotor cortex, the brain region responsible for planning and executing voluntary movements. Sensorimotor rhythms include mu rhythms (8-12 Hz) and beta rhythms (18-26 Hz), which change in amplitude when a person…
- Slow Cortical Potential(also: SCP, Slow Cortical Potentials)
- Gradual voltage shifts in the electrical activity of the brain, occurring over periods of several hundred milliseconds to several seconds. Slow cortical potentials reflect changes in the overall excitability level of cortical neural networks — negative shifts indicate increased…
- Speech Neuroprosthesis(also: Speech BCI, Speech Brain-Computer Interface)
- A brain-computer interface that decodes neural activity associated with attempted or imagined speech and converts it into text, synthesized voice, or both. Speech neuroprostheses are designed for people with anarthria or severe dysarthria from ALS, brainstem stroke, locked-in…
