About Dr Sarah McKay, neuroscientist, author, and brain health expert

Dr Sarah McKay: Neuroscientist & Science Communicator

I’m an Oxford-educated neuroscientist, author, and speaker, and I run The Neuroscience Academy – online training in brain health and applied neuroscience for health and helping professionals.

I share brain science with a clear, science-first voice ... no fluff, no headline grabs ... just solid research, translated into useful, real-world insights.

I live on Sydney’s Northern Beaches, where I write, teach, swim in the ocean year-round, and turn complex neuroscience into practical tools and accessible stories.

c. Baby Brain: The surprising neuroscience of how pregnancy and motherhood sculpt our brains and change our minds (for the better)

Around 85% of women become mothers. And most of us agree that pregnancy and parenthood profoundly change us physically, psychologically, socially and spiritually.

Neuroscientists now believe becoming a mother (a process called matrescence) is a significant neurological transition.

Sadly, mothers’ minds and brains are mainly absent from popular pregnancy books and social media posts... unless that is, there’s a discussion about what could go badly wrong: baby blues, postnatal depression or ditzy ‘baby brain’. It’s as if mothers should expect to lose their minds.

Baby Brain will change your mind about baby brain!

d. Keynote Speaker

I am an experienced keynote speaker presenting to audiences including TikTok-Australia, EY, Vogue, Winona School, Business Chicks, CalmBirth and the Resolution Institute.

I have a special interest on women's brain health, covering how the brain changes during childlhood, puberty, pregnancy, menopause, and healthy ageing.

My keynotes also explore the neurobiology of uncertainty, brain-to-brain synchrony and trust, and the practical application of neuroscience in leadership, HR, and health.

I offer tailored keynotes, workshops, book talks and engaging Q&A sessions, delivered either in person or virtually, to meet the specific needs of your audience.

“I have known Sarah since we were graduate students. She was always an extremely sharp thinker about science; she liked to challenge things but with an openness to possibility. It's hard to maintain sharp-edged curiosity without becoming cynical. Sarah did that as a graduate student, and she does that now.”

Professor Andrew Huberman, Huberman Lab Podcast.

e. Free Micro-Training in Brain science.

Perfect for people too busy for extensive (and expensive) courses.

This free micro-training in applied neuroscience is quick, entertaining, and immediately applicable to everyday life.

You'll be taught one simple neuroscience concept every day including:

The interplay between emotions and thinking.
The importance of social connection and brain health.
Creating and breaking habits.
Neuroplasticity and behaviour change in adulthood.
Using visualisation to master skills and emotions.
Effective goal-setting, even when you're burned out.

Quickly upskill in basic brain science.

Get maximum impact with minimal time investment!

Dr. McKay is a vivacious and entertaining guide into the fascinating world of brain science.

f. The Women's Brain Book:

The Neuroscience of Health, Hormones and Happiness

As women, understanding how our brains are sculpted by many factors — including genes and hormones, life experiences, society and culture, thoughts, feelings, and personal beliefs — is key to better health and well-being.

The story begins in the womb and takes a fascinating, informative, and truly eye-opening journey through infancy and girlhood, puberty and the menstrual cycle, the teenage years, mental health, pregnancy and motherhood, menopause, and finally, into old age.

Learn exactly what happens inside your brain and body as you move through all of the important phases of your lives and the unique and often misunderstood effects of female biology and hormones.

Fully revised 2nd edition due 2025!

Due to the rapid pace (it was a long time coming!) of women's brain health research, a comprehensive updated 2nd edition of The Women's Brain Book will be released in July 2025.
