Solving Neurodegenerative Diseases: A New Puzzle Piece

January 16, 2025

Neurodegenerative diseases are like intricate puzzles that scientists are working hard to solve. They affect both small components (like molecules and cells) and large aspects (such as physiology) of the brain. Traditional tools aren't doing the job well, but a new technology called microfluidics mi

Tremor Types: Seeing the Difference in the Brain

January 15, 2025

Essential Tremor (ET) is a common condition where people experience shakiness, especially during movement. Some people with ET also have tremors when they're resting, which is known as resting ET or rET. While we know ET changes the brain's white matter, we don't know much about the differences betw

How Short and Long Brain Connections Help Us Age Gracefully

January 14, 2025

As we grow older, our brains change in interesting ways. They still function well thanks to a mix of local and long-distance connections. These connections help the brain process information both locally and across different areas. But as time passes, these connections can weaken, which might affect

Unlocking Brain Clues: Alzheimer's in Down Syndrome

January 14, 2025

Ever wondered how Alzheimer's disease affects the brains of people with Down syndrome? Scientists are exploring if changes in brain thickness and size can help figure out the disease's stages. It's like trying to solve a brain puzzle: do these changes look the same as in other inherited forms of Alz

Sleep and Parkinson's: A New Way to Find Rest

January 12, 2025

Sleep can be a real struggle for people with Parkinson's disease. But there's a treatment that might help - deep brain stimulation (DBS). Instead of just helping with shaking and stiffness, scientists have found it also improves sleep. They looked at brain waves in an area called the subthalamic nuc

How Tonic and Phasic Neuron Activity Affect Dopamine Release

January 11, 2025

You know how some brain cells, called dopamine neurons, send signals by releasing dopamine? Well, these neurons have two main types of activity: regular, low-frequency signals (tonic) that they produce on their own, and quick bursts (phasic) that happen when they get inputs from other cells.

How Brain Networks Change After Stopping Seizure Meds

January 11, 2025

Researchers wanted to understand how the brain's network changes affect seizure relapse when people stop taking their seizure medication. They looked at 24 people who stayed seizure-free (SF-group), 22 who had seizures again (SR-group), and 46 healthy individuals (Control group). They used brain sca

Brain Tumors and Leaky Blood Vessels: A New Way to Spot Them?

January 10, 2025

Brain tumors can mess up the blood-brain barrier (BBB), which is like a protective fence around blood vessels in the brain. Currently, doctors rely on their eyes and a special brain scan called DSC MRI to see if the BBB is damaged. However, this method might miss subtle issues and can't be used on p
