Parkinson’s disease may originate in the intestines

Two months after injecting alpha-synuclein into the intestines of rats, researchers discovered the proteins had traveled to the brain via peripheral nerves. Four months later, the pathology was greater. Additionally, the protein had traveled to the heart. The study supports the hypothesis that Parkinson's disease may begin in the intestinal system before migrating to the brain.

Neurological brain markers might detect risk for psychotic disorders

Researchers have identified a new biomarker for psychosis in the striatal dopamine neurons. Those at risk for psychosis showed increased activation in the striatum for positive feedback and decreased activation when faced with negative feedback.

Genetic variation contributes to individual differences in pleasure

What we find pleasurable may be down to our genetics. Researchers found nucleus accumbens activation and physical anhedonia were influenced by shared genes. The experience of pleasure and physical anhedonia also appear to share some of the same genes.

Brain protein mutation from child with autism causes autism-like behavioral change in mice

Researchers implanted a genetic mutation that encodes the DAT protein from a child with ASD into mice. The mice began to exhibit autism-like behavioral deficits. Mice with the DAT T356M mutation had reduced social interaction and a loss in social dominance. The mice also demonstrated an increase in hyperactivity. At the physiological level, the researchers found impaired striatal dopamine transmission and clearance.

The science behind giving up

Pnoc neurons in the paranigral ventral tegmental area become active when mice seek rewards. Stimulating these neurons with optogenetics promotes avoidance behaviors. Researchers say ventral tegmental area dopamine neuron NOPR expression is necessary to limit reward-seeking behavior.

Pioneering new study on dopamine and stress

A neuroimaging study on house sparrows reveals changes in the dopaminergic system could be a physiological mechanism underlying the negative behavioral effects of chronic stress. The findings shed light on stress and resilience in wildlife and humans.

Bacterial intestinal infections may trigger Parkinson’s disease

Mice infected with bacteria that cause mild intestinal infections exhibited Parkinson's like symptoms later in life. The findings provide a pathophysiological model in which intestinal infections may act as a trigger for Parkinson's disease.

Research shows that drinking Matcha tea can reduce anxiety

Matcha tea can help reduce anxiety, a new study reports. Mice given Match extract showed a reduction in anxious behaviors. The calming effects are a result of Matcha activating dopamine and serotonin receptors.
