Tracing Male and Female Brain Development
Louann Brizendine, M.D., is a neurobiologist and practicing clinician who specializes in the relationship dynamics that result from the neurobiology of male and female brains. A faculty member at the University of California, San Francisco, she’s the author of the bestsellers The Female Brain and The Male Brain. Louann joins Dan Siegel, Rick Hanson, Michael Gelb, Norman Doidge, and Stephen Porges for our all-new streaming-video webcast series.

The neural song circuit is enhanced in male compared with female zebra finches due to differential rates of incorporation and survival of cells between the sexes. Two double-label immunohistochemical experiments were conducted to increase the understanding of relationships between newly generated cells (marked with bromodeoxyuridine [BrdU]) and those expressing brain-derived neurotrophic factor (BDNF) and vimentin, a marker for radial glia. The song systems of males and females were investigated at posthatching day 25 during a heightened period of sexual differentiation (following BrdU injections on days 6-10) and in adulthood (following a parallel injection paradigm). In both HVC (proper name) and the robust nucleus of the arcopallium (RA), about half of the BrdU-positive cells expressed BDNF across sexes and ages. Less than 10% of the BDNF-positive cells expressed BrdU, but this percentage was greater in juveniles than adults. Across both brain regions, more BDNF-positive cells were detected in males compared with females. In RA, the number of these cells was also greater in juveniles than adults. In HVC, the average cross-sectional area covered by the vimentin labeling was greater in males than females and in juveniles compared with adults. In RA, more vimentin was detected in juveniles than adults, and within adults it was greater in females. In juveniles only, BrdU-positive cells appeared in contact with vimentin-labeled fibers in HVC, RA, and Area X. Collectively, the results are consistent with roles of BDNF- and vimentin-labeled cells influencing sexually differentiated plasticity of the song circuit.

Human Brains Are Neither 'Male' Nor 'Female' - D-brief
You’ll see when you listen to her in this quick video clip about Stage 3—the Adolescent Brain—where she focuses on how the hormones of puberty drive a new level of differentiation between the neurobiology and behavior of adolescent men and women.


In her conversation with me—airing for the first time this Wednesday at 1:00 pm Eastern—Louann Brizendine explores the complex and extraordinary development of the brain through a lifetime, paying special attention to neurobiology’s role in the differentiation between the male and female brain
