- Ear-EEG(also: Around-the-Ear EEG, cEEGrid)
- Ear-EEG refers to electroencephalography (EEG) recorded using electrodes placed in and around the ear canal rather than on the scalp. Consumer-grade ear-EEG devices such as cEEGrid sensors are unobtrusive, easy to wear without hair preparation, and suitable for everyday…
- Intracortical BCI(also: iBCI, Intracortical Brain-Computer Interface)
- A brain-computer interface that records neural activity directly from inside the cerebral cortex, typically using surgically implanted microelectrode arrays such as the Utah array. Compared with non-invasive EEG-based BCIs, intracortical BCIs offer dramatically higher…
- 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…
