Apathy or a lack of motivation is a disabling condition making patients feel that they “just can’t be bothered to do things”. Apathy is very common in Parkinson’s disease, affecting up to 70% of patients and causing
Dopamine, often referred as “the happiness hormone”, is one of the most prominent messenger molecules in the human brain. It is a precursor of noradrenaline and adrenaline, which are neurotransmitters as well. Most people heard about dopamine
The glucose sensor is an excellent example of a point-of-care test: patients conduct measurements at home, it is fast, low-cost, and offers easy interpretation of results. There is a growing market to develop similar devices for testing
Circadian clocks rule our lives. In the course of evolution, almost all living creatures developed molecular mechanisms that optimally prepare our bodies for predictable , recurring events related to the regular alternations between day and night. This
Do the different actions required to gain a palatable food make a difference in the activation of the brain?
The motivated behaviour that underlies the food intake is a complex process mediated by various neural circuits. One of these is the mesolimbic system that employs the dopamine (DA) as neurotransmitter. In particular, in the responsiveness to
Citicoline is marketed as a nutritional supplement in the United States and has been shown to influence cellular metabolism in the brain and to contribute to the synthesis of essential neurotransmitters including acetylcholine and dopamine. Citicoline is
Our body organs, such as the brain, are made of different cells that talk to each other by releasing natural chemicals outside the cells. The free chemicals then attach to specialized proteins named receptors, which are anchored
