Functional neuronal circuits emerge in the absence of developmental activity - Nature Communications
How functional neuronal circuits are established during development is not fully understood. Here the authors show, by raising fish in the dark and under anesthesia, that brain activity is not needed for the development of complex, decision-making circuits.

Harvard scientists just revealed a remarkable fact about brain development
Harvard researchers discovered that zebrafish can develop complex neural circuits and behaviors without sensory input, suggesting genetics alone may shape brain connectivity.

“In the age-old question of nature versus nurture, we land decisively on the side of nature,” Barabási told PsyPost. “We challenge recent focuses on learning, from artificial intelligence to self-improvement, showcasing the remarkable contribution of development to our innate capacities. This suggests that certain elements of our behavior and personality are ‘baked in,’ or part of our developmental package, and a growth mindset can expand and empower this innate potential.”
