Memory

The visual cortex, where the brain processes visual input, is made like a stack of pancakes. In a new study, scientists sought to determine the role in several visual phenomena of a receptor on neurons in layer 4.

Study probing visual memory and amblyopia unveils many-layered mystery

Scientists pinpoint the role of a receptor in vision degradation in amblyopia.

In a study using machine-generated art to understand what makes a picture memorable, researchers found that the images people remembered best had bright colors, simple backgrounds, and subjects centered prominently in the frame.

What makes an image memorable? Ask a computer

An artificial intelligence model developed at MIT shows in striking detail what makes some images stick in our minds.

Images from two-photon microscopy track the comings and goings of dendritic spines (key infrastructure for neural connections called synapses) in a mouse brain. Top row: A spine present on day 14 is gone by two weeks later. Bottom row: A spine emerges around day 28 and sticks around.

How brain cells pick which connections to keep

Novel study shows protein CPG15 acts as a molecular proxy of experience to mark synapses for stabilization.

MIT neuroscientists have identified patterns of brain activity that underlie our ability to interpret sensory input based on our expectations and past experiences.

How expectation influences perception

Neuroscientists find brain activity patterns that encode our beliefs and affect how we interpret the world around us.

By exposing mice to a unique combination of light and sound, MIT neuroscientists have shown that they can improve cognitive and memory impairments similar to those seen in Alzheimer’s patients. At left, the mouse cortex shows a reduction in amyloid plaques following visual and auditory stimulation, compared to the untreated mouse at right.

Neuroscientists are debating the nature and meaning of neural activity during the critical moment of working memory when people must hold information in mind.

The debate over how working memory works

Scientists present dueling theories in the high-stakes quest to understand how we hold and juggle multiple pieces of information in mind.
