Bob’s Book: When Brains Dream

We all wish for better memories. But how are memories stored? For all our neuroscience, we still do not know even the level in the brain where memories are stored—from inside neurons to long brain circuits. We do know that the synapses between neurons in the brain are critical, but how those chemical changes mean a specific memory remains a mystery. Learn more from Dr. Stickgold on what we know and where we need to go.

The New England Mental Health Technology Transfer Center Network (MHTTC) hosted another webinar led by Tony Cunningham, Ph.D., a postdoctoral Research Fellow at Harvard Medical School, Beth Israel Deaconess Medical Center, and Boston College as he expanded upon his previous webinar discussion on the importance of sleep during the pandemic. In this presentation, Dr. Cunningham discussed some of the findings from sleep research conducted during the COVID-19 pandemic, including results from his Boston College COVID-19 Sleep and Well-Being study.

If consciousness is 100% physical, we would have to conclude that the same kind of consciousness that we experience as humans can be generated by non-biological entities (eventually). Conversely, if non-biological consciousness would somehow, someday, prove impossible, then consciousness would have to embed some nonphysical aspect. But how would we ever know? Learn more from Dr. Stickgold.

Robert Stickgold in conversation with co-author Antonio Zadra

Why do we dream? Do dreams hold psychological meaning or are they merely the reflection of random brain activity? What purpose do dreams serve?

When Brains Dream addresses these core questions about dreams while illuminating the most up-to-date science in the field. Written by two world-renowned sleep and dream researchers, it debunks common myths that we only dream in REM sleep, for example—while acknowledging the mysteries that persist around both the science and experience of dreaming.

Antonio Zadra and Robert Stickgold bring together state-of-the-art neuroscientific ideas and findings to propose a new and innovative model of dream function called NEXTUP―Network Exploration to Understand Possibilities. By detailing this model’s workings, they help readers understand key features of several types of dreams, from prophetic dreams to nightmares and lucid dreams. When Brains Dream reveals recent discoveries about the sleeping brain and the many ways in which dreams are psychologically, and neurologically, meaningful experiences; explores a host of dream-related disorders; and explains how dreams can facilitate creativity and be a source of personal insight.

Robert Stickgold is a professor at Harvard Medical School and director of the Center for Sleep and Cognition. His writing has appeared in Scientific American and Newsweek.

Antonio Zadra is a sleep and dream scientist at the Hôpital du Sacré-Coeur's Center for Advanced Research in Sleep Medicine and professor of psychology at the Université de Montréal. In addition to numerous publications on sleep, dreams, and dream-related disorders, Dr. Zadra is the co-author of When Brains Dream: Exploring the Science and Mystery of Sleep.

The New England Mental Health Technology Transfer Center Network (MHTTC) hosted a webinar led by Tony Cunningham, Ph.D., a postdoctoral Research Fellow at Harvard Medical School, Beth Israel Deaconess Medical Center, and Boston College.

Why do we spend so much of our lives not awake? Learn about the vital function that sleep plays in our lives in this brief conversation with Dr. Stickgold.

How well do you remember your dreams? Have you ever had a dream about something you were doing earlier in the day—especially if you were doing it when you nodded off? If you’re a sleep researcher, like Harvard psychiatrist Robert Stickgold, who wants to induce a specific dream in your patients, Tetris is apparently the way to go. He had subjects play the popular video game before going to sleep, and then had them record their dreams when they woke up. What was really interesting though, is what happened when he conducted the same experiment on amnesiacs.

The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries.
