Marijuana use while pregnant boosts risk of children's sleep problems

As many as 7% of moms-to-be use marijuana while pregnant, and that number is rising fast as more use it to quell morning sickness. But new research suggests such use could have a lasting impact on the fetal brain, influencing[…]

Sniffing out smell: How the brain organizes information about odors

Neuroscientists describe for the first time how relationships between different odors are encoded in the brain. The findings suggest a mechanism that may explain why individuals have common but highly personalized experiences with smell, and inform efforts better understand how[…]

Fever-associated seizures after vaccination do not affect development, behavior

Now a new study has found there is no difference in developmental and behavioral outcomes for children who have febrile seizures after vaccination, children who have febrile seizures not associated with vaccination and children who have never had a seizure.

Why memory-forming neurons are vulnerable to Alzheimer's

Scientists have used advanced technology to 'micro-dissect' the first brain cells to perish in Alzheimer's disease. The result is a short list of genes that could represent new drug targets.

New approach to treating certain neurological diseases

Medical researchers have developed a potential treatment method for Pelizaeus-Merzbacher disease (PMD), a fatal neurological disorder that produces severe movement, motor and cognitive dysfunction in children. It results from genetic mutations that prevent the body from properly making myelin, the[…]

How does our brain fold? Study reveals new genetic insights

Problems with brain folding are linked with neurological conditions like autism, anorexia and schizophrenia, but there are currently no ways to detect, prevent or treat misfolding. New research offers genetic insights into the folding process, an important step towards developing[…]

Findings weaken notion that size equals strength for neural connections

Among a new study's many surprises about synaptic plasticity may be a new approach to addressing Fragile X syndrome: Finding and targeting a ''Protein X'' that appears to promote shrinkage of dendritic spines.

Auditory hallucinations rooted in aberrant brain connectivity

A study reports that auditory hallucinations, a phenomenon in which people hear voices or other sounds, may arise through altered brain connectivity between sensory and cognitive processing areas.

Lab-grown 'mini-brains' suggest COVID-19 virus can infect human brain cells

Researchers have found that organoids known as 'mini-brains' can be infected by the SARS-CoV-2 virus that causes COVID-19.

Discovery of new step in how brain cells work could lead to new therapies for epilepsy

Researchers have identified a critical new step in how brain cells function in people with one of the most common forms of epilepsy. This could lead to new treatment approaches for people with drug-resistant epilepsy.

Novel pathology could improve diagnosis and treatment of Huntington's and other diseases

Scientists have discovered a novel pathology that occurs in several human neurodegenerative diseases, including Huntington's disease. The article describes how SAFB1 expression occurs in both spinocerebellar ataxias and Huntington's disease and may be a common marker of these conditions, which[…]

Pernicious effects of stigma

The recent killings of unarmed individuals have sparked a national conversation about the treatment of Black people -- and other minorities -- in the United States.

Closer threats inspire a more primitive kind of fear

Your brain handles a perceived threat differently depending on how close it is to you. If it's far away, you engage more problem-solving areas of the brain. But up close, your animal instincts jump into action and there isn't as[…]

Older adults share fewer memories as they age

Researchers used a smartphone app to 'eavesdrop' on older adult conversations. They found that the older a person is, the less likely they are to share memories of past experiences.

Lifting weights makes your nervous system stronger, too

Gym-goers may get frustrated when they don't see results from weightlifting right away, but their efforts are not in vain: the first few weeks of training strengthen the nervous system, not muscles.

Artificial intelligence identifies, locates seizures in real-time

Research has shown that understanding brain activity as a network instead of readings from an EEG allow for more accurate and efficient detection of seizures in real-time.

Plasticity may make neurons vulnerable to Alzheimer's disease

Neurons that regularly remodel are more prone to the dysfunctions linked to the disease's onset, a new experimental and computational study finds.
