Dopamine signals when a fear can be forgotten
A 2 by 2 array of panels that each show a hairpin-like shape of blue stained cells. The left column is laberled "Ambient light/sound." The right column is labeled "40Hz Stimulation." The panels in the 40Hz column show more yellow arrows pointing white blotches than the panels in the ambient column.

A simple animal’s response to sickness highlights the nervous system’s surprising degrees of flexibility
A black brain shown in a side view glows blue. The amygdala, a small almond-shaped structure toward the bottome center stands out especially. In the background there are theater masks signifying emotions.

Research Feature
Emerging evidence shows how brain waves help to knit our internal thoughts and external awareness together into an organized, unified whole

With programmable pixels, novel sensor improves imaging of neural activity

June 7, 2024
Research Findings
New camera chip design allows for optimizing each pixel’s timing to maximize signal to noise ratio when tracking real-time visual indicator of neural voltage

Microscope system sharpens scientists’ view of neural circuit connections

Research Findings
A newly described technology improves the clarity and speed of using two-photon microscopy to image synapses in the live brain

Study models how ketamine’s molecular action leads to its effects on the brain

May 20, 2024
Research Findings
New research addresses a gap in understanding how ketamine’s impact on individual neurons leads to pervasive and profound changes in brain network function.

How the brain is flexible enough for a complex world (without being thrown into chaos)

May 13, 2024
Research Findings
Many neurons exhibit “mixed selectivity.” They can integrate multiple inputs and participate in multiple computations. Mechanisms such as oscillations and neuromodulators recruit their participation and tune them to focus on the relevant information.

Autism symptoms sometimes improve amid fever, so a research team will study how to make that a therapy

May 8, 2024
New Research
With support from The Marcus Foundation, an MIT neuroscientist and a Harvard Medical School immunologist will study the “fever effect” in an effort to devise therapies that mimic its beneficial effects.

In the brain, bursts of beta rhythms implement cognitive control

April 23, 2024
Research Findings
Bursts of brain rhythms with “beta” frequencies control where and when neurons in the cortex process sensory information and plan responses. Studying these bursts would improve understanding of cognition and clinical disorders, researchers write.

Paper: To understand cognition—and its dysfunction—neuroscientists must learn its rhythms

April 17, 2024
Research Findings
Thought emerges and is controlled in the brain via the rhythmically and spatially coordinated activity of millions of neurons, scientists argue in a new article. Understanding cognition and its disorders requires studying it at that level.

Plasticity and place: Study shows a key neural mechanism of remembering locations

March 25, 2024
Research Findings
Scientists have now observed how the brain’s place cells stave off inhibitory input in the process of establishing their tuning to specific locations. The study shows that signaling by endocannabinoids is required.

Movement disorder ALS and cognitive disorder FTLD show strong molecular overlaps, new study shows

March 22, 2024
Research Findings
Single-cell gene expression patterns in the brain’s motor and frontal cortex, and evidence from follow-up experiments, reveal many shared cellular and molecular similarities that could be targeted for potential treatment
