Beacon Biosignals is mapping the brain during sleep
Founded by Jake Donoghue PhD ’19 and former MIT researcher Jarrett Revels, the company is creating an AI-driven platform to help diagnose and treat disease.
How neurons sense bacteria in the gut
Neural interaction with bacteria has important effects on animal brains. A new study investigates how neurons sense bacteria by revealing, in nematodes, the bacterial signals that a key neuron detects.
With navigating nematodes, scientists map out how brains implement behaviors
MIT scientists create a detailed map of exactly what happens in the brains of C. elegans worms when they “follow their nose” to savor attractive odors or avoid unappealing ones.
Turning muscles into motors gives static organs new life
A new biohybrid system developed at MIT is the first living implant that uses rewired nerves to revive paralyzed organs.
After 16 years leading Picower Institute, Li-Huei Tsai will sharpen focus on research, teaching
Tsai, who has grown the MIT neuroscience institute, will increase focus on research including Alzheimer’s disease and Down syndrome.
Brain circuit needed to incorporate new information may be linked to schizophrenia
Impairments of this circuit may help to explain why some people with schizophrenia lose touch with reality.
Scientists discover genetics behind leaky brain blood vessels in Rett syndrome
By showing the problem derives from genetic mutations that lead to overexpression of a microRNA, MIT researchers’ study points to potential treatment.
Neurons receive precisely tailored teaching signals as we learn
New work suggests the brain can deliver neuron-specific feedback during learning — resembling the error signals that drive machine learning.
3 Questions: Exploring the mechanisms underlying changes during infection
Zuri Sullivan, a new assistant professor of biology and Whitehead Institute member, studies why we get sick, and whether aspects of illness, such as disrupted appetite, contribute to host defense.
Fragile X study uncovers brain wave biomarker bridging humans and mice
Researchers find mice modeling the autism spectrum disorder fragile X syndrome exhibit the same pattern of differences in low-frequency waves as humans — a new marker for treatment studies.
AI algorithm enables tracking of vital white matter pathways
Opening a new window on the brainstem, a new tool reliably and finely resolves distinct nerve bundles in live diffusion MRI scans, revealing signs of injury or disease.
A satellite language network in the brain
Researchers find a component of the brain’s dedicated language network in the cerebellum, a region better known for coordinating movement.
How a unique class of neurons may set the table for brain development
Somatostatin-expressing neurons follow a unique trajectory when forming connections in the visual cortex that may help establish the conditions needed for sensory experience to refine circuits.
Biology-based brain model matches animals in learning, enables new discovery
New “biomimetic” model of brain circuits and function at multiple scales produced naturalistic dynamics and learning, and even identified curious behavior by some neurons.
To flexibly organize thought, the brain makes use of space
MIT researchers tested their theory of spatial computing, which holds that the brain recruits and controls ad hoc groups of neurons for cognitive tasks by applying brain waves to patches of the cortex.
