When keeping track of location a particular region of the brain, the lateral septum, pays special attention to where the reward is located, compared to another region, the hippocampus, that tracks location without that same bias.

Like a treasure map, brain region emphasizes reward location

The lateral septum encodes spatial information with a special emphasis on where the reward lies.

In Alzheimer's disease, the blood-brain barrier can become disrupted by the accumulation of amyloid protein, especially in people who carry a genetic variant called APOE4. This 3D rendering of an APOE4-carrying engineered blood vessel shows heavy accumulation of amyloid protein (green).

Study finds path for addressing Alzheimer’s blood-brain barrier impairment

MIT researchers pinpoint mechanism and demonstrate that drugs could help.

Researchers are studying the role of the immune system molecule IL-6 in Huntington's disease, which leads to neurodegeneration in a region of the brain called the striatum. In this figure from a prior study, green staining highlights Stat3 in the striatum. Stat3 is a major transducer of IL-6 signaling.

A new technology called ELAST transforms tissues, such as this slab of human brain, to make them reversibly stretchable or compressible, as well as much more durable. This allows them to be repeatedly stretched out or squished down thin for much faster infusion of labeling probes, which labs use to highlight cells or molecules under the microscope.

Making tissue stretchable, compressible, and nearly indestructible

Chemical process called ELAST allows labeling probes to infuse more quickly, and makes samples tough enough for repeated handling.

MIT scientists have identified a potential new strategy for treating Fragile X syndrome, a disorder that is the leading heritable cause of intellectual disability and autism. The team includes, from left–right: Amanda Coranado, Arnold Heynen, Mark Bear, Rebecca Senter, Laura Stoppel, and Patrick McCamphill.

In this figure, neurons in the bottom row, which are missing the HDAC1 gene, show higher levels of DNA damage (green) than normal neurons.

Study finds that aging neurons accumulate DNA damage

Reactivating an enzyme that promotes DNA repair can help to reverse age-related cognitive decline in mice.

MIT researchers have found that a protein called SYT7 appears to limit activity at neural connections called synapses. Here, synapses glowing light green are engaged in neurotransmitter release.

Study finds “volume dial” for turning neural communication up or down

The protein Synaptotagmin 7 limits supply of neurotransmitter-containing vesicles for release at synapses.

“When you encounter something new, there are some really new and notable stimuli, but you already know quite a bit about that particular experience, because it’s a similar kind of experience to what you have already had before,” says Susumu Tonegawa, a professor of biology and neuroscience at the RIKEN-MIT Laboratory of Neural Circuit Genetics at MIT’s Picower Institute for Learning and Me...

The same neurons that store feelings of reward also store memories that suppress fearful ones, a new study shows. In this image, the broader population of Ppp1r1b neurons is labeled green while neurons storing a specific fear extinction memory are labeled red.

With these neurons, extinguishing fear is its own reward

The same neurons responsible for encoding reward also form new memories to suppress fearful ones.
