The Brain’s Thalamus
“The thalamus is a sensory control center of the brain that integrates and relays sensory inputs,” explains Johannes Larsch. Sensory information is processed on its route to the thalamus, first in the retina and then in the tectum, a major visual center of the vertebrate brain.
By the time the information arrives in the thalamus, it has already been filtered for social cues, such as the jerky movements of a potential conspecific.

Johannes Larsch’s team nevertheless found a way to elucidate the importance of the visual system in social interactions. The scientists developed an experimental virtual reality setup for zebrafish larvae that simulates conspecifics. All that was needed was a pro...
Integration of Information:
