Evolving Brain - Mysteries of the Brain

The video explores the evolution of brains across species, focusing on the research of neurobiologist Molina Hale. Hale studies fish brains, particularly zebrafish, to understand how neural circuits generate movement. The video highlights the simplicity of the zebrafish's brain, allowing scientists to observe neuron activity. It also examines the startle circuit in fish, providing insights into neural circuit evolution. By studying these simple systems, scientists aim to uncover the mysteries of the human brain.

In what way do the startle circuits of the Australian lungfish and zebrafish provide insight into evolutionary biology?

What challenges do scientists face in understanding how the circuitry in the human brain works?
