Counting Neurons with Dr. Suzana Herculano-Houzel (BS 133)

Counting Neurons with Dr. Suzana Herculano-Houzel (BS 133)

This is an interview with Dr. Suzana Herculano-Houzel, the scientist who discovered that the human brain has an average of 86 billion neurons, which is significantly less than the 100 billion that was long assumed. She has also written a wonderful book called The Human Advantage: How Our Brains Became Remarkable.

Exploring Glial Cells with R. Douglas Fields (BSP 69)

Recent research has discovered that glial cells (the non-neuronal cells that make up about 85% of the cells in the human nervous system) actually do more than just support neurons.  In Episode 69 of the Brain Science Podcast, I explore some of these recent discoveries with pioneering researcher, R. Douglas Fields, PhD.  Dr. Fields is the author of The Other Brain: From Dementia to Schizophrenia, How New Discoveries about the Brain Are Revolutionizing Medicine and Science.  The Other Brain provides a compelling introduction to this exciting new field.  It is aimed at general readers, but it should also be on the must-read list for all students of neuroscience.
