If you do not snooze you lose: Sleep seen as essential for the brain
Scientists are providing a fuller understanding of the essential role that sleep plays in brain health, identifying an abrupt transition at about 2.4 years of age when its primary purpose shifts from brain building to maintenance and repair.
Why time sometimes flies or drags: How brain creates experience of time
Time-sensitive neurons fatigue and skew our perception of time. On some days, time flies by, while on others it seems to drag on. A new study from JNeurosci reveals why: Time-sensitive neurons get worn out and skew our perceptions of time.
Researchers map anxiety in brain
Researchers in Italy have identified structural and functional differences in the brains of people with temporary and chronic anxiety. These differences may serve to improve the diagnosis and treatment of anxiety.
Sustained high blood pressure may damage brain vessels
Having high blood pressure for long periods may increase the chance of small vessel damage in the brain, which has been linked to dementia and stroke, according to a new study.
How COVID-19 can damage brain
Not only does COVID-19 damage the lungs, heart and kidneys, it can also cause severe brain damage — with patients suffering neurological conditions including paranoia and hallucinations, a British scientific study has revealed.
Researchers track brain receptor as it transmits or inhibits neural signals
For the first time, researchers in the lab of CSHL Professor Hiro Furukawa have been able to track each atom in the NMDA receptor, an important brain protein, as it transmits or inhibits neural signals.
COVID-19 may be linked to brain complications, but does it cause them?
A new study has found further evidence of a correlation between severe cases of COVID-19 and brain complications, but researchers say they still aren't sure whether those complications are directly caused by the disease.
Repeated head impacts, brain injury increase risk for depression
Head injuries experienced while young may increase a person's risk for depression and dementia decades later, according to a study published by the journal Neurology.
Has your loved one made this mistake in conversation recently?
Dementia warning sign
Dementia is a heart-wrenching diagnosis for anyone to receive. Being told that your cognitive abilities will decline is a tough pill to swallow but the shock also ripples through the family. In fact, family should play a role in managing dementia in more ways than one. As people get older, it is important to watch for subtle changes in your loved one.
Genetic variation in a brain-cleansing water channel affects human sleep
The reason why we sleep remains an unresolved question of the 21st century. Research by Sara Marie Ulv Larsen, Sebastian Camillo Holst and colleagues from the Neurobiology Research Unit at the University Hospital Copenhagen, published in the open access journal PLoS Biology, now shows that the depth of non-rapid-eye-movement (nonREM) sleep in humans is associated with different genetic versions of a gene that encodes a water channel involved in fluid flow in the brain.
How coronavirus may affect the brain
A pattern is emerging among COVID-19 patients arriving at hospitals in New York: Beyond fever, cough and shortness of breath, some are deeply disoriented to the point of not knowing where they are or what year it is.
Study explores the effects of bilingualism on the developing brain
Recent research in the field of neuroscience suggests that knowing and speaking more than one language could impact the speaker's brain structure.
'Brain stimulator' may boost stroke recovery
Researchers say it has been cumbersome to deliver magnetic stimulation to stroke patients, which enhances the ability of nerve cells to adapt, but a new device manages to do it as a wearable.
Vesuvius volcano victim had his brain turned into glass, study claims
The devastating volcanic eruption of Mount Vesuvius in A.D. 79 — which wiped out settlements including Pompeii and Herculaneum in blasts of molten rock and ash — may have turned the brains of some of its sorry victims to glass, a new study concluded.
Study identifies brain networks that play crucial role in suicide risk
An international team of researchers has identified key networks within the brain which they say interact to increase the risk that an individual will think about — or attempt — suicide.
