An MIT-led research team has discovered evidence that a classic visual illusion called simultaneous brightness contrast, such as the one seen here, relies on brightness estimation that takes place in the retina, not the brain’s visual cortex. In this image, the two small discs appear to have different brightness despite having identical luminance.

Study sheds light on a classic visual illusion

Neuroscientists delve into how background brightness influences our perception of an object.

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 algorithm, called the Fast Loaded Dice Roller (FLDR), simulates the roll of dice to produce random integers. The dice, in this case, could have any number of sides, and they are “loaded,” or weighted, to make some sides more likely to come up than others.

Algorithm quickly simulates a roll of loaded dice

Approach for generating numbers at random may help analyses of complex systems, from Earth’s climate to financial markets.

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.
