Making Decisions Without a Brain

The video explores decision-making in organisms, focusing on protists like Stentor and Paramecium. It discusses Jennings' early 20th-century experiments on protists' responses to stimuli, such as light and irritants, and the hierarchy of responses they exhibit. The video highlights the complexity of even single-celled organisms' decision-making processes and the challenges in replicating Jennings' findings. It concludes with the implications of these studies for understanding the microcosmos.
