Robert Stickgold on the Importance of Sleep

This is a fantastic interview with one of my favorite former professors, Robert Stickgold, who discusses the many important functions that sleep has. He touches on the unity of consciousness, immune function, memory processing, endocrine function and obesity, emotional regulation, and improvement on physical tasks. Most importantly he reminds us not to think of sleep as a waste of time. …

How Does Toxoplasmosis Affect the Brain?

Perry digs into Milgram’s notes, letters, and book drafts, and also meets with subjects, assistants, and researchers to provide an in-depth look at what is perhaps the best-known …

Students form groups of 5: of these 4 students will play the roles of dendrites and one student will be the axon hillock, summing the messages received from the dendrites. The dendrites each receive a handful of face-down playing …
