In this image of a mouse visual cortex, astrocytes (stained red) appear about as abundant as neurons (green).

MIT neuroscientists give "invisible" cells a new look

With a new grant, a Picower Institute team is studying the role of astrocytes, which may partner with neurons to process information in the brain.

This image shows neurons in the CA3 region of the hippocampus, which is important for memory encoding and retrieval. Nuclei of the CA3 neurons are labeled in green and their dendrites in red, and the smaller specks of green above represent axons projecting to the CA3 neurons from the dentate gyrus.

Study reveals molecular mechanisms of memory formation

Neuroscientists discover a cellular pathway that encodes memories by strengthening specific synapses.

Our daily lives include hundreds of routine habits, made up of many smaller actions, such as picking up our toothbrush, squeezing toothpaste onto it, and then lifting the brush to our mouth. This process of grouping behaviors together into a single routine is known as “chunking.” MIT neuroscientists have now found that certain neurons in the brain are responsible for marking the beginning and ...

Distinctive brain pattern helps habits form

Study identifies neurons that fire at the beginning and end of a behavior as it becomes a habit.

MIT neuroscientists have found evidence that the brain’s ability to control what it’s thinking about relies on low-frequency brain waves known as beta rhythms.

New study reveals how brain waves control working memory

Brain rhythms act as a gate for information entering and leaving the mind.

Sometimes items can easily be grouped by their appearance, such as these apples, but sometimes the brain must use a different mode of thought to find a more abstract similarity, such as that between a drill and screwdriver.

Study: Distinct brain rhythms and regions help us reason about categories

High-frequency gamma oscillations sort similar-looking objects; lower-frequency beta oscillations kick in when connections are more abstract.

Various 3-D views of the basolateral amygdala show the arrangement of neurons that project to the nucleus accumbens (green), the hippocampus (blue), or the central amygdala (red).

Lifting the veil on "valence," brain study reveals roots of desire and dislike

Researchers map the amygdala's distinct but diverse and dynamic neighborhoods where feelings are assigned.

The image shows the locus coeruleus, which drives neuronal circuits of the hippocampus and enables novel contextual memory. The red staining shows norepinephrine transporter (NET)-positive cells, indicating the locus coeruleus. The green staining shows adeno-associated virus (AAV)-mediated expressions of light-sensitive inhibitory opsin, archaerhodopsin (Arch). The blue staining shows all cells in...

How the brain selectively remembers new places

Neuroscientists identify a circuit that helps the brain record memories of new locations.

Using a novel analytical method they have developed, MIT researchers analyzed raw brain activity data (B). The spectrogram shows decreased noise and increased frequency resolution, or contrast (E and F) compared to standard spectral analysis methods (C and D).

Recalculating time

A novel algorithm enables statistical analysis of time series data.

As part of an investigation into the nature of humans' physical intuitions, MIT researchers trained a neural network to predict how unstably stacked blocks would respond to the force of gravity.

Computer systems predict objects’ responses to physical forces

Results may help explain how humans do the same thing.
