What Your Brain Is Doing When You’re Not Doing Anything
When your mind is wandering, your brain’s “default mode” network is active. Its discovery 20 years ago inspired a raft of research into networks of brain regions and how they interact with each other.
The Brain Region That Controls Movement Also Guides Feelings
The cerebellum is responsible for far more than coordinating movement. New techniques reveal that it is, in fact, a hub of sensory and emotional processing in the brain.
New Cell Atlases Reveal Untold Variety in the Brain and Beyond
Recent efforts to map every cell in the human body have researchers floored by unfathomable diversity, with many thousands of subtly different types of cells in the human brain alone.
She Studies How Addiction Hijacks Learning in the Brain
Erin Calipari works to understand how drugs like opioids and cocaine alter learning circuits and neurochemistry in one of the country’s epicenters of substance use disorder and addiction.
In the Gut’s ‘Second Brain,’ Key Agents of Health Emerge
Sitting alongside the neurons in your enteric nervous system are underappreciated glial cells, which play key roles in digestion and disease that scientists are only just starting to understand.
Why the Human Brain Perceives Small Numbers Better
The discovery that the brain has different systems for representing small and large numbers provokes new questions about memory, attention and mathematics.
Bats Use the Same Brain Cells to Map Physical and Social Worlds
New research in social bats raises the intriguing possibility that evolution can reprogram the brain’s “place cells,” which are typically associated with location, to encode all kinds of environmental information.
These Cells Spark Electricity in the Brain. They’re Not Neurons.
For decades, researchers have debated whether brain cells called astrocytes can signal like neurons. Researchers recently published the best evidence yet that some astrocytes are part of the electrical conversation.
