Brainstem and spinal cord help control hand movements (English, Level A1)

There is a network that controls hand movements.
The brainstem is part of this network.
The spinal cord is also part of the network.
Researchers find connections between brainstem and spinal cord.
Scientists study mice and human volunteers with simple tasks.
They use brain scans to see activity during movement.
The same regions are active in both species.
The top spinal segments act as relay centers.
This discovery may help people after stroke.

Brain wave patterns and memory

Scientists recorded electrical activity from patients with epilepsy who had brain electrodes. They found distinct spatial wave patterns that changed with behaviour and could predict what people remembered about 70% of the time.

Shrews shrink organs to survive winter

Eurasian common shrews shrink their brains and other organs in winter, a seasonal change called Dehnel’s phenomenon. Two new studies link genetic and chromosomal changes to this shrinking and to the regrowth that occurs in spring.

Nasal spray reverses signs of brain aging in models

Researchers developed a nasal spray that delivers extracellular vesicles with microRNAs to the brain. In preclinical models it reduced inflammation, restored neuronal mitochondria and improved memory, but human tests are still needed.

Lower mGlu5 receptor found across autistic adult brains

A study in The American Journal of Psychiatry found lower availability of a glutamate receptor called mGlu5 across the brains of autistic adults. Researchers used PET, MRI and EEG and say the result could affect future diagnosis and treatment.
