A new biosensing technology developed by researchers from Hokkaido University and Toppan using an animal model may signal a breakthrough in early Alzheimer’s disease diagnosis. The biosensing technology developed by the team using mouse models is able to detect amyloid β (Aβ) accumulation in the brain by measuring Aβ-binding exosomes in the blood. As clinical ...

Scientists have long wondered how the hippocampus alternates episodic memory formation and recall. While we know that these two competing processes – learning and remembering – are controlled by the hippocampus, scientists have struggled to observe how the brain knows when and how to shift from recalling past information to learning and responding to novel ...

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that currently affects about 4.42 in every 1,000,000 people worldwide.

These effects can begin long past the initial viral incubation period, and the symptoms can prove surprising. In a recent study at the Dartmouth College Geisel School of Medicine, researchers used cognitive tests to assess a potential ...
