The Picower Institute for Learning and Memory found that the two closely related neuronal subtypes differed from each other in how they expressed more than 800 genes. By manipulating genes whose expression differed most prominently, the scientists were then able to show how they produced several of the observable differences between the cells.

Boston MA (SPX) Aug 24, 2023 - To understand the full relationship between brain activity and behavior, scientists have needed a way to map this relationship for all of the neurons across a whole brain - a so far insurmountable c

Researchers compared a pair of superficially similar motor neurons in fruit flies to examine how their differing use of the same genome produced distinctions in form and function.

An MIT team has produced an atlas of how most cells, and the circuits they take part in, encode a worm's actions. The atlas reveals the underlying “logic” of how an animal brain produces a sophisticated and flexible repertoire of behaviors, even as its environmental circumstances change.

To understand the full relationship between brain activity and behavior, scientists have needed a way to map this relationship for all of the neurons across a whole brain-;a so far insurmountable challenge.

We have sort of an intuitive understanding of a big need in artificial intelligence and machine learning, which has to do with making sure that systems converge well, ...

Boston MA (SPX) Aug 17, 2023 - Artificial neural networks, ubiquitous machine-learning models that can be trained to complete many tasks, are so called because their architecture is inspired by the way biological neurons process

When a student finds the MIT Summer Research Program in Biology and Neuroscience, it helps them find their future in research. 

Researchers hypothesize that a powerful type of AI model known as a transformer could be implemented in the brain through networks of neuron and astrocyte cells. The work could offer insights into how the brain works and help scientists understand why transformers are so effective at machine-learning tasks.

The research is helping to construct a framework to understand how algorithms influence social interactions.
