- Mechanoreceptor(also: Tactile Receptor, Touch Receptor)
- A sensory receptor in the skin that responds to mechanical pressure or distortion, enabling the sense of touch. Different types of mechanoreceptors detect various tactile qualities: Meissner corpuscles sense light touch and low-frequency vibration (10-65 Hz), Pacinian corpuscles…
- 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…
- Muscle Fatigue(also: Motor fatigue)
- A decline in the capacity of a muscle or muscle group to generate force or sustain activity after prolonged or repeated exertion. In human-computer interaction, muscle fatigue is a central concern for input modalities requiring sustained or repetitive motion — notably mid-air…
