Artificial intelligence tool detects male-female-related differences in brain structure

Artificial intelligence (AI) computer programs that process MRI results show differences in how the brains of men and women are organized at a cellular level, a new study shows. These variations were spotted in white matter, tissue primarily located in…

Some brain cells age faster and are more prevalent in Alzheimer’s

Engineers have discovered that some brain cells age more rapidly than others, and they are disproportionately abundant in individuals afflicted with Alzheimer’s disease. Additionally, researchers observed male-female-specific differences in the aging p…

Innovative ‘mini-brains’ could revolutionize Alzheimer’s treatment

New research could revolutionize the way Alzheimer’s and other brain-related diseases are diagnosed and treated — by building tiny brains in a petri dish.

Study reveals patients with brain injuries who died after withdrawal of life support may have recovered

Analysis of 1,392 patients with traumatic brain injuries (TBIs) found that some patients for whom life support was withdrawn may have survived and recovered some level of independence a few months after injury. Families are often asked to make decision…

How the brain is flexible enough for a complex world (without being thrown into chaos)

Many neurons exhibit ‘mixed selectivity,’ meaning they can integrate multiple inputs and participate in multiple computations. Mechanisms such as oscillations and neuromodulators recruit their participation and tune them to focus on the relevant inform…

A fragment of human brain, mapped in exquisite detail

Researchers have created the largest synaptic-resolution, 3D reconstruction of a piece of human brain to date, showing in vivid detail each cell and its web of neural connections in a piece of human temporal cortex about half the size of a rice grain.

High school student helps transform ‘crazy idea’ into innovative research tool

A ‘crazy idea’ hatched during a walk in the woods and first tested by a high school student is now an innovative research tool used by scientists worldwide to predict neurotransmitters in fruit fly connectomes.

Study shows heightened sensitivity to PTSD in autism

A new study shows that a mild stress is enough to trigger post-traumatic stress disorder (PTSD) in mouse models of autism spectrum disorder (ASD). Researchers demonstrated that the two disorders share a reciprocal relationship, identifying a predisposi…

Brain mechanisms underlying sensory hypersensitivity in a mouse model of autism spectrum disorder

A research team has identified the primary cause of sensory hypersensitivity in a mouse model of autism spectrum disorders (ASD).

‘Wraparound’ implants represent new approach to treating spinal cord injuries

A tiny, flexible electronic device that wraps around the spinal cord could represent a new approach to the treatment of spinal injuries, which can cause profound disability and paralysis. A team of engineers, neuroscientists and surgeons developed the …
