Researchers at MIT and the Allen Institute for Brain Science have developed a new modified version of the rabies virus that stops replicating once it infects a cell, allowing it to deliver its genetic cargo without harming the cell.

Viral tool traces long-term neuron activity

New technique is nontoxic to cells, should allow scientists to study neuron function for months or years instead of weeks.

MIT researchers have developed a light-sensitive protein that can be embedded into neuron membranes, where it emits a fluorescent signal that indicates how much voltage a particular cell is experiencing. This could allow scientists to study how neurons behave, millisecond by millisecond, as the brain performs a particular function.

Seeing the brain's electrical activity

Fluorescent sensor allows imaging of neurons' electrical communications, without electrodes.

MIT cognitive scientists have found that conversation between an adult and a child appears to change the child’s brain.

Back-and-forth exchanges boost children’s brain response to language

Study finds engaging young children in conversation is more important for brain development than “dumping words” on them.

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.

“I am fascinated by how people work, why we do what we do, and why we think what we think,” says senior and Marshall Scholar Liang Zhou.

Decoding human cognition

MIT senior and Marshall Scholar Liang Zhou wants to elucidate the neural basis for our thoughts and intuitions.

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.
