Modalities

A medical imaging technique that uses strong magnetic fields and radio waves to create detailed images of organs and tissues within the body, especially the brain, without using ionizing radiation (like X-rays).

A topographic or graphic record, as a function of time, of magnetic fields associated with the electrical activity of the brain.

An invasive device composed of numerous microscopic electrodes designed to be implanted directly into the brain's cortex.[2, 29] MEAs offer the highest spatial resolution of any BCI modality, capable of recording the action potentials (spikes) of individual neurons or small neuronal populations, which provides the fine-grained information necessary for complex control tasks like operating a multi-fingered robotic hand.[13, 30]

Combined spiking activity from small neuronal populations.
