Social Isolation Provokes Brain Activity Similar to That Seen During Hunger Cravings
Activity in the substantia nigra is similar following a day of social isolation as it is following a day of starvation. Since the coronavirus pandemic began in the spring, many people have only seen their close friends and loved ones … Continue reading

The “online brain”: how the Internet may be changing our cognition
The impact of the Internet across multiple aspects of modern society is clear. However, the influence that it may have on our brain structure and functioning remains a central topic of investigation. Here we draw on recent psychological, psychiatric and … Continue reading
Affect in the aging brain
We report the first functional neuroimaging meta-analysis on age-related differences in adult neural activity during affect. We identified and coded experimental contrasts from 27 studies (published 1997-2018) with 490 older adults (55-87 years, Mage=69 years) and 470 younger adults (18-39 … Continue reading
How the brain consolidates memory during deep sleep
Research strongly suggests that sleep, which constitutes about a third of our lives, is crucial for learning and forming long-term memories. But exactly how such memory is formed is not well understood and remains, despite considerable research, a central question … Continue reading
Sleep Is Irreplaceable for the Recovery of the Brain
Resting is no substitute for deep sleep when it comes to keeping up with the intensive performance demands of daily life. Sleep is ubiquitous in animals and humans and vital for healthy functioning. Thus, sleep after training improves performance on … Continue reading
Revisiting the global workspace orchestrating the hierarchical organization of the human brain
A central challenge in neuroscience is how the brain organizes the information necessary to orchestrate behaviour. Arguably, this whole-brain orchestration is carried out by a core subset of integrative brain regions, a ‘global workspace’, but its constitutive regions remain unclear. … Continue reading

How the Brain Manages Short-Term Memories
A new computational algorithm shows how the brain maintains information in the short term using specific types of neurons. If you’ve ever forgotten something mere seconds after it was at the forefront of your mind–the name of a dish you … Continue reading
What Loneliness Looks Like in the Brain
Neuroimaging reveals several differences in the brains of lonely people, specifically in the default network. Researchers found greater gray matter density and stronger connectivity in the default networks of lonely people. This holiday season will be a lonely one for … Continue reading

Your Brain Makes You a Different Person Every Day
Brain “plasticity” is one of the great discoveries in modern science, but neuroscientist David Eagleman thinks the word is misleading. Unlike plastic, which molds and then retains a particular shape, the brain’s physical structure is continually in flux. But Eagleman … Continue reading

Baby’s First Breath Triggers Life-Saving Changes in the Brain
A baby’s first breath triggers a signaling system in the brain stem that helps support early breathing. The findings shed light on how problems with this neuropeptide system can increase the risk of SIDS. There are few moments in life … Continue reading
