This image contains three illustrations depicting human skulls and brains in a glowing, neon blue color against a black background. The top illustration shows a side view of a skull with the brain visible inside. The middle illustration shows a frontal view of a skull, with bright spots of light concentrated in the area of the brain. The bottom illustration depicts a human head outline with a network of glowing, interconnected nodes resembling neural pathways radiating outward from the brain area. These visuals seem to symbolize different levels or stages of cognitive function, intelligence, or enlightenment, potentially relating to the "Galaxy Brain" meme concept mentioned in the title.
