stimulation

Flinker says the team plans tests to assess further how and whether the corollary discharge circuit is active immediately before hallucinations induced during brain stimulation.

Because the spinal cord transmits sensations to the brain from all over the body, the position of the leads is adjusted so that the patients feel the stimulation at the site of the pain.

Among these is non-invasive brain stimulation: a term encompassing a set of techniques that can affect brain functions externally and noninvasively, without the need for surgery or implants.

It reflects how nerve cells, or neurons, in the brain's cortex respond to stimulation and plays a key role in cognitive functions like learning and memory, information processing, decision making, motor control, wakefulness and sleep.

EEG style measurements show clear neural reactions in the crustacean's brain during mechanical or chemical stimulation.
