Researchers unravel a novel mechanism regulating gene expression in the brain that could guide solutions to circadian and other disorders

A collaborative effort has shed valuable light on how monoamine neurotransmitters such as serotonin, dopamine, and now histamine help regulate brain physiology and behavior through chemical bonding of these monoamines to histone proteins, the core DNA-…

Words activate hidden brain processes shaping emotions, decisions, and behavior

In a study, scientists have shown neurotransmitters in the human brain are active during the processing of the emotional content of language, providing new understanding into how people interpret the significance of words.

Overcoming spasticity to help paraplegics walk again

Thanks to new high-frequency electrical stimulation that blocks spasticity, two paralyzed patients suffering from muscle stiffness after spinal cord injury benefit from rehabilitation protocols for walking again.

Study challenges traditional risk factors for brain health in the oldest-old

A study has found cardiovascular conditions such as high blood pressure and diabetes, which are known to contribute to brain blood vessel damage in younger populations, not to be associated with an increased risk of such harm in individuals 90 and older.

Study shows head trauma may activate latent viruses, leading to neurodegeneration

Researchers have uncovered mechanisms that may link head injuries and concussions to the emergence of neurodegenerative disease, pointing to latent viruses lurking in most of our brains that may be activated by the jolt, leading to inflammation and acc…

Mixed signals: How the brain interprets social cues

Researchers have found that smell and sound signals merge in the mouse brain’s hearing center, influencing social behaviors like pup retrieval. The discovery may lead to a better understanding of how neurological conditions such as autism affect a pers…

Loneliness linked to higher risk of heart disease and stroke and susceptibility to infection

Interactions with friends and family may keep us healthy because they boost our immune system and reduce our risk of diseases such as heart disease, stroke and type 2 diabetes, new research suggests. Researchers drew this conclusion after studying prot…

Brain study challenges long-held views about Parkinson’s movement disorders

Researchers uncovered new findings about involuntary muscle movements that come with long-term administration of Parkinson’s drug levodopa.

‘Smooth brain’ disorders may share a common cause  —  and potential treatment

Lissencephaly is a spectrum of rare, genetic disorders in which the brain fails to develop its hallmark folds. The disorders are often associated with seizures and intellectual disability and currently there are no available treatments. A new study, ho…

Study reveals that sleep prevents unwanted memories from intruding

The link between poor sleep and mental health problems could be related to deficits in brain regions that keep unwanted thoughts out of mind.
