The effects of oxytocin on social anxiety depend on location, location, location

The findings of the study show that oxytocin produced in the BNST increases stress-induced social anxiety behaviors in mice. This may provide an explanation as to why oxytocin can sometimes have antisocial effects.

Major deficits in addressing mental health needs of asylum seekers

A new study of asylum seekers in Germany suggests that, among those with symptoms of depression, anxiety, or posttraumatic stress disorder (PTSD), few receive a diagnosis from the health care system, and of those diagnosed, many do not receive treatment.

Traveling brain waves help detect hard-to-see objects

A team of scientists has uncovered details of the neural mechanisms underlying the perception of objects. They found that patterns of neural signals, called traveling brain waves, exist in the visual system of the awake brain and are organized to allow…

Cortex-wide variation of neuronal cellular energy levels depending on the sleep-wake states

The brain is assumed to exert homeostatic functions to always keep the cellular energy status constant, this has not been proven. Researchers discovered that cortical neuronal intracellular concentrations of ATP, the major cellular energy metabolite, g…

Study confirms genetic link in cerebral palsy

An international research team including the University of Adelaide has found further evidence that rare gene mutations can cause cerebral palsy, findings which could lead to earlier diagnosis and new treatments for this devastating movement disorder.

A hydrogel that could help repair damaged nerves

Injuries to peripheral nerves — tissues that transmit bioelectrical signals from the brain to the rest of the body — often result in chronic pain, neurologic disorders, paralysis or disability. Now, researchers have developed a stretchable conductive…

Study finds odor-sensing neuron regeneration process is adaptive

Results show that diminished odor stimulation reduces the number of newly-generated neurons that express particular odorant receptors, indicating a selective alteration in the neurogenesis of these neuron subtypes.

Evidence of Alzheimer’s, Parkinson’s and MND in brains of young people exposed to dirty air

After examining the brainstems of 186 young Mexico City residents aged between 11 months and 27 years of age, researchers, found markers not only of Alzheimer’s disease, but also of Parkinson’s and of motor neuron disease (MND) too. These markers of di…

Millimeter-precision drug delivery to the brain

Focused ultrasound waves help researchers to deliver drugs to the brain with pinpoint accuracy, in other words only to where their effect is desired. This method is set to enable treatment of psychiatric and neurological disorders and tumours with fewe…

How the brain helps us navigate social differences

Researchers found that, among pairs of people who had very different socioeconomic backgrounds – calculated according to education level and family income – there was a higher level of activity in an area of the frontal lobe called the left dorsolatera…
