- Beta Rhythm (Beta Wave, Beta Oscillation)
- A pattern of electrical brain activity oscillating at approximately 13-30 Hz, commonly recorded over the sensorimotor cortex. Like mu rhythms, beta rhythms are modulated by movement and motor imagery …
- C-tactile Afferents (CT afferents, C-tactile fibres, CT fibres)
- Unmyelinated, slow-conducting nerve fibres found in hairy skin that respond selectively to gentle, slow stroking touch at velocities of approximately 1-10 cm/s. C-tactile afferents are strongly associ…
- Fovea (Foveal Vision, Fovea Centralis)
- The small, central area of the retina responsible for sharp, detailed vision, covering approximately 1 degree of visual angle. The fovea contains the highest density of cone photoreceptors and provide…
- Frisson (Aesthetic Chills, Musical Chills, Piloerection)
- A psychophysiological response to music, art, or other aesthetic stimuli characterised by a pleasurable shiver or chills sensation accompanied by piloerection (goosebumps) and transient increases in h…
- Kinesthetics (Kinaesthetics, Kinesthesia, Kinesthetic sense)
- The sense of body position, movement, and muscular effort derived from receptors in muscles, tendons, and joints. Kinesthetics is closely related to — and often used interchangeably with — propriocept…
- Motor Cortex (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 somato…
- Mu Rhythm (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 perfor…
- Muscle Fatigue (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…
- Slow Cortical Potential (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 excit…
- Trichromat (Trichromacy, Trichromatic Vision)
- A person with typical colour vision based on three types of functional cone cells (L, M, and S cones) in the retina, each sensitive to different wavelengths of light corresponding roughly to long (red…
