Associate Director for Communications, Vanderbilt Brain Institute
Interested in comparative neuroanatomy, cellular composition of brains, brain morphology, brain evolution, metabolic cost of body and brain, sleep requirement across species, feeding time, and really interested in how all of these are tied together. Writes about neuroscience and science in general for the public; recently published The Human Advantage: A New Understanding of How Our Brain Became Remarkable (MIT Press, 2016).
A TED talk on how the human brain compares to others and how it came to have the largest number of cortical neurons of any brain can be seen here.
