High blood pressure in your 30s is associated with worse brain health in your 70s

High blood pressure in early adulthood is associated with worse brain health in late life, according to a new study. Men, compared to women, may be more vulnerable to the detrimental effects of high blood pressure on the brain for some brain regions.

Activating adult-born neurons through deep brain stimulation alleviates Alzheimer’s symptoms in rodent models

People with Alzheimer’s disease develop defects in cognitive functions like memory as well as problems with noncognitive functions that can lead to anxiety and depression. Investigators used mice to study a process through which new neurons are generat…

Using photons as neurotransmitters to control the activity of neurons

Researchers have developed a system that connects two neurons by using light-emitting enzymes and light-sensitive ion channels.

Fibromyalgia: Pain out of control

Feeling like we have a degree of control makes us tolerate pain better. In the case of fibromyalgia, however, this simply doesn’t work. A study provides clues as to why.

Traumatic brain injury interferes with immune system cells’ recycling process in brain cells

In a new study, researchers found that after traumatic brain injury, the brain’s immune system cells’ internal recycling function slowed dramatically, allowing waste products to build up and interfere with recovery from injury.

Overwhelmed? Your astrocytes can help with that

A brimming inbox on Monday morning sets your head spinning. You take a moment to breathe and your mind clears enough to survey the emails one by one. This calming effect occurs thanks to a newly discovered brain circuit involving a lesser-known type of…

How genes, brain characteristics and intelligence are connected

Genes influence different structures and the function of the brain. These in turn explain differences in behavior. Analyzing all three aspects at once is a challenge — but has now been achieved.

Tiny eye movements are under a surprising degree of cognitive control

A very subtle and seemingly random type of eye movement called ocular drift can be influenced by prior knowledge of the expected visual target, suggesting a surprising level of cognitive control over the eyes, according to a new study.

How do we know if our brain is capable of repairing itself?

Is our brain able to regenerate? And can we harness this regenerative potential during aging or in neurodegenerative conditions? These questions sparked intense controversy within the field of neuroscience for many years. A new study shows why there ar…

Jet lag’s harmful health impacts found to be caused by biological clock misalignment

New research zeroes in on the root cause of adverse health effects from disruption of the body’s circadian rhythms, which typically occurs from jet lag and rotating work shifts.
