Vitamin D’s Crucial Role in Dopamine Function and Schizophrenia

Neuroscientists discovered how vitamin D deficiency impacts the development of neurons, contributing to disorders such as schizophrenia. Using innovative technology, they were able to observe that a lack of vitamin D not only changes neuron growth but also affects the brain's dopamine release mechanism. They found dopamine release was enhanced in cells grown in the presence of vitamin D, compared to a control.

Whether Physical Exertion Feels Easy or Hard May Be Due to Dopamine Levels

Dopamine plays a vital role in why exercise and physical activity feels easy to some, but exhausting to others, a new study reports. The findings could lead to more effective ways to help people begin and stick to exercise regimes, and sheds new light on fatigue associated with depression and Parkinson's disease.

Danger or Pleasure? How We Learn to Tell the Difference

Scientists have discovered that somatostatin-expressing neurons in the amygdala help distinguish between good and bad stimuli, responding differently to rewards versus punishments and even different types of rewards. Inhibiting these neurons in mice resulted in an inability to learn to associate sounds with rewards or punishments, providing potential insight into addiction and opportunities for new treatments.

New Discovery Reveals Sex-Specific Causes of Depression Triggered by Stress Hormones Dysfunction

Men are more likely to have a dysregulated HPA axis that is associated with depressive symptoms, while women have higher levels of binding proteins for stress hormones that may prevent dysregulation of the HPA axis. The findings shed new light on how stress hormones impact dopamine transmission and how this impacts depression on a sex-specific basis.

Multiple Substance Use Disorders May Share Inherited Genetic Signature

A common genetic signature has been linked to an increased risk of substance use disorders from smoking addiction to addiction to narcotics. The findings could pave the way to the development of new therapies for substance use disorder and may help diagnose those at risk to multiple substance use disorders.

Dial for Tuning Dopamine and Environmental Signals Found in Parkinson’s

Study reveals how signals from the environment integrate with genetic information that influences the survival and health of neurons, providing new insights into how Parkinson's disease may develop. Findings reveal the TNK2 gene mutations lead to the degeneration of dopamine producing neurons, resulting in Parkinson's disease pathology.
