Brain

"You have suffered damage to your central processing unit."
"You mean my brain?"
"That was a joke. It is meant to put you at ease."

―IG-11 and Din Djarin

The bottled brain of a B'omarr monk

The brain was an organ in lifeforms that served as the center for consciousness and reasoning. Species like the Cereans and the Siniteen had larger brains than average. The Siniteen named Pons Limbic was nicknamed "Brainiac" as he could mentally calculate hyperspace jumps.

Members of the B'omarr Order had their brains removed and placed in jars filled with nutrient fluid, which could then be attached to spider-like droid walkers, allowing the monk to move about.

Darth Sidious had the clone troopers' brains implanted with behavioral modification biochips to enact Order 66. The AJ^6 cyborg construct was a brain implant used by Imperial workers to improve productivity, but at the cost of an individual's personality.
