Are Your Eyes Part of Your Brain?

The video explores the complex definition of the brain, challenging the traditional view of it as a dense clump of neurons within the skull. It discusses how neurons and neurotransmitters are found throughout the body, influencing functions like vision and sleep. The video also examines how different organisms, such as octopuses and hydras, have unique brain systems, questioning the boundaries of what constitutes a brain. Ultimately, it highlights the importance of understanding brain interactions with the body to advance neurobiology and medical treatments.

What are the implications of expanding the definition of the brain beyond the organ in the skull?

How do neurons in the body contribute to our understanding of brain functions?

In what ways do neurotransmitters play a role in defining brain functions?

What role do the eyes and heart play in the broader definition of the brain?

How does the study of Hydra contribute to our understanding of brain-like functions in organisms without a traditional brain?
