- Microelectrode Array(also: Utah Array, MEA)
- A small grid of fine recording electrodes (typically 96 silicon shanks in a 4mm x 4mm Utah array) surgically implanted into the cerebral cortex to record the electrical activity of individual neurons and small neural populations. Microelectrode arrays are the sensing front-end…
- Motor Cortex(also: Primary Motor Cortex, M1)
- The region of the cerebral cortex responsible for planning, controlling, and executing voluntary movements. Located in the frontal lobe along the precentral gyrus, the motor cortex is organised somatotopically — different areas control different body parts. In brain-computer…
- Mu Rhythm(also: Mu Wave, Mu Oscillation)
- A pattern of electrical brain activity oscillating at approximately 8-12 Hz, recorded over the sensorimotor cortex. Mu rhythms are suppressed (desynchronised) when a person performs or imagines performing a movement, a phenomenon known as event-related desynchronisation. In…
