A type of flatworm could be a new weapon in the hunt for better ways to treat a group of diseases that can cause extreme sensitivity to light, facial hair growth, and hallucinations, according to a study published in the journal eLife.
New research shows that when mice experience chronic stress, neurons within part of their brain's fear and anxiety center, the amygdala, retract. It also suggests how such changes could be prevented.
Results of the first study of its kind to link abnormalities in circadian rhythms to changes in specific neurotransmitters in people with bipolar disorder will be published this week in the journal Biological Psychiatry.
A Purdue University study shows that honeybees collect the vast majority of their pollen from plants other than crops, even in areas dominated by corn and soybeans, and that pollen is consistently contaminated with a host of agricultural and urban pesticides throughout the growing season.
A region of the brain that responds to bad experiences has the opposite reaction to expectations of aversive events in people with depression compared to healthy adults, finds a new UCL study funded by the Medical Research Council.
'Paediatric Digestive Health Across Europe', commissioned by United European Gastroenterology, highlights how the current health burden and economic pressure of pediatric digestive health issues, in particular the increasing levels of childhood obesity, have become a pandemic issue throughout the continent.
Researchers using contrast-enhanced MRI have identified leakages in the blood-brain barrier of people with early Alzheimer's disease, according to a new study. The results suggest that increased BBB permeability may represent a key mechanism in the early stages of the disease.
Monkeys who could not use their MD were less able to respond to changes that required them to adapt their behavior to continue making the right choices to maximize rewards. They also struggled with their decisions when they were presented with a choice of several differently rewarded options.
Research by Dr. Shernaz Bamji at the University of British Columbia uncovers the action mechanism of an enzyme called DHHC9 in normal development and function of neural networks in the brain. Mutations in DHHC9 have been identified in patients suffering from X-linked Intellectual Disability. Dr. Bamji's work shows DHHC9 plays a vital role in promoting the growth and branching of neurons and in maintaining the balance between excitatory and inhibitory signals being formed onto neurons.
Research at the RIKEN Brain Science Institute in Japan has revealed that a molecule involved in fish reproduction activates the brain via the nose. The pheromone is released by female zebrafish and sensed by smell receptors in the noses of the males. The neural pathway and brain areas involved in transforming this molecular messenger into courtship behavior in fish were also identified and reported in Nature Neuroscience on May 30.
