Different anesthetics, same result: unconsciousness by shifting brainwave phase

May 12, 2025
Research Findings
MIT study finds that an easily measurable brain wave shift may be a universal marker of unconsciousness under anesthesia

The how and why of the brain’s division across hemispheres

May 12, 2025
Research Findings
Why does the brain split visual spatial perception between its hemispheres? A new review examines the advantages and trade-offs, and how the brain ultimately makes vision feel seamless.

Dopamine signals when a fear can be forgotten

April 28, 2025
Research Findings
Study shows how a dopamine circuit between two brain regions enables mice to extinguish fear after a peril has passed.

MIT Down syndrome researchers work on ways to ensure a healthy lifespan

Picower Events
An Alana Down Syndrome Center webinar, co-sponsored by the Massachusetts Down Syndrome Congress, presented numerous MIT studies that all share the goal of improving health throughout life for people with trisomy 21.

In Down syndrome mice, 40Hz light and sound improve cognition, neurogenesis, connectivity

April 24, 2025
Research Findngs
Study provides new evidence that sensory stimulation of gamma-frequency brain rhythm may promote broad-based restorative neurological health response.

With Searle Scholar award, Fan will study serotonin role in memory

April 22, 2025
Picower People
Assistant Professor Linlin Fan will apply her lab’s precise “all-optical” techniques to study how serotonin might influence plasticity in memory, and whether psychedelics affect that.

In kids, EEG monitoring of consciousness safely reduces anesthetic use

April 21, 2025
Research Findings
Clinical trial finds several outcomes improved for young children when an anesthesiologist observed their brain waves to guide dosing of sevoflurane during surgery.

A simple animal’s response to sickness highlights the nervous system’s surprising degrees of flexibility

April 8, 2025
Research Findings
Upon infection, the C. elegans worm reshuffles the roles of brain cells and flips the functions of some of the chemicals it uses to regulate behavior.

Molecules that fight infection also act on the brain, inducing anxiety or sociability

April 7, 2025
Research Findings
New research on a cytokine called IL-17 adds to growing evidence that immune molecules can influence behavior during illness.

Gloria Choi earns Samsung Ho-Am Prize for Medicine

Picower People
Honor recognizes Choi’s research on connections between the immune and central nervous systems and their relevance to autism and other disorders

A neuron’s neighbors

March 14, 2025
Research Feature
The field is called neuroscience, but neurons alone can’t operate your brain. Research is revealing how non-neural cells indispensably contribute to function, and why their roles can make them promising treatment targets in disease.

Review: Evidence expanding that 40Hz gamma stimulation promotes brain health

March 3, 2025
A decade of studies from labs around the world provide a growing evidence base that increasing the power of the brain’s gamma rhythms could help fight Alzheimer’s, and perhaps other, neurological diseases.
