Tool detects hidden signs of consciousness after brain injury
Tool detects hidden signs of consciousness after brain injury Researchers have developed an AI tool called SeeMe that detects hidden signs of consciousness after brain injury, which can identify patients who are conscious but unable to show it up to four days earlier than traditional clinical exams. The tool uses high-resolution video and computer vision […]

Tiny windows of time may be key to your hearing
Tiny windows of time may be key to your hearing Researchers have found that the auditory cortex processes speech at a fixed time window, regardless of the speed of speech, challenging the idea that our brain’s processing should be yoked to the structure of words or syllables. The study used advanced neural recording techniques to […]

Brain’s electrical activity could predict Alzheimer’s development
Brain’s electrical activity could predict Alzheimer’s development Researchers have identified a brain-based biomarker that can predict whether mild cognitive impairment will develop into Alzheimer’s disease using electrical activity from neurons. A custom-built tool, called the Spectral Events Toolbox, was used to analyze brain activity recordings from 85 patients diagnosed with mild cognitive impairment and monitored […]

Scientists grow mini brain in a lab
Scientists grow mini brain in a lab Scientists at Johns Hopkins University have successfully grown a mini brain organoid, complete with neural tissues and rudimentary blood vessels, marking an advance in research into neuropsychiatric disorders such as autism. The multi-region brain organoid (MRBO) is the first whole-brain organoid to be generated, allowing researchers to study […]

Speech-based AI tool flags sign of Parkinson’s
Speech-based AI tool flags sign of Parkinson’s A new speech-based AI tool has been developed to help assess signs of Parkinson’s disease, with nearly 86% accuracy. The tool uses a web-based screening test that asks users to recite two pangrams, which are short sentences using all 26 letters of the alphabet. Users simply read aloud […]

Your left and right brain hear language differently − a neuroscientist explains how
Your left and right brain hear language differently − a neuroscientist explains how Research suggests that the left and right hemispheres of the brain process language differently, with the left hemisphere typically dominating speech perception. The development of neural circuits in the auditory cortex, responsible for processing sound, follows a specific timeline, with the right […]

Why do we yawn?
Why do we yawn? Yawning is an instinct that occurs in all animals, including cats. The exact reason for yawning in humans is still unknown and not definitively studied. Some experts suggest that yawning may be related to sleep needs, hunger, or boredom, but these theories are not conclusive. Fetuses have been observed yawning, suggesting […]

Billy Joel has excess fluid in his brain – a neurologist explains what happens when this protective liquid gets out of balance
Billy Joel has excess fluid in his brain – a neurologist explains what happens when this protective liquid gets out of balance Billy Joel has been diagnosed with normal pressure hydrocephalus (NPH), a condition where excess cerebrospinal fluid (CSF) accumulates in the brain’s cavities, leading to enlarged ventricles and pressure on surrounding tissue. CSF is […]

1 region of the brain links all your senses
1 region of the brain links all your senses A new study published in NeuroImage has found that all five senses stimulate a region of the brain that controls consciousness. The study, led by Yale researcher Aya Khalaf, used fMRI data from 1,561 healthy adult participants to analyze how different senses interact with each other […]
