Neuroscientists identify brain circuit necessary for memory formation
When we visit a friend or go to the beach, our brain stores a short-term memory of the experience in a part of the brain called the hippocampus. Those memories are later "consolidated"—that is, transferred to another part ...

Neuroscientists find brain activity patterns that encode our beliefs
For decades, research has shown that our perception of the world is influenced by our expectations. These expectations, also called "prior beliefs," help us make sense of what we are perceiving in the present, based on similar ...

Study pinpoints Alzheimer's plaque emergence early and deep in the brain
Long before symptoms like memory loss even emerge, the underlying pathology of Alzheimer's disease, such as an accumulation of amyloid protein plaques, is well underway in the brain. A longtime goal of the field has been ...

'Organs-on-a-chip' system sheds light on how bacteria in the human digestive tract may influence neurological diseases
In many ways, our brain and our digestive tract are deeply connected. Feeling nervous may lead to physical pain in the stomach, while hunger signals from the gut make us feel irritable. Recent studies have even suggested ...

Neuroscientists identify two neuron populations that encode happy or fearful memories
Our emotional state is governed partly by a tiny brain structure known as the amygdala, which is responsible for processing positive emotions such as happiness, and negative ones such as fear and anxiety.

Distinctive brain pattern may underlie dyslexia
A distinctive neural signature found in the brains of people with dyslexia may explain why these individuals have difficulty learning to read, according to a new study from MIT neuroscientists.

New MRI sensor can image activity deep within the brain
Calcium is a critical signaling molecule for most cells, and it is especially important in neurons. Imaging calcium in brain cells can reveal how neurons communicate with each other; however, current imaging techniques can ...

Inside the adult ADHD brain
About 11 percent of school-age children in the United States have been diagnosed with attention deficit hyperactivity disorder (ADHD). While many of these children eventually "outgrow" the disorder, some carry their difficulties ...

Cracking the code that relates brain and behavior in a simple animal
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. But after inventing ...
