Sugar consumption can be reduced by tonic activation of dopamine reward pathway

Rewarding ( pleasurable ) and aversive events give us dissimilar perceptions, which powerfully shape our decisions and therefore behavioral outcomes. In fact, chemical changes, which take place in our brain, are very different under these opposite circumstances.

Measuring motivation in Parkinson’s disease through the eyes response to money

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

Promiscuous drugs exemplified by dopamine receptor ligands

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

Introducing Thermal Wave Transport Analysis (TWTA): a thermal technique for dopamine detection

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

The mood stabilizer valproic acid tunes up abnormal circadian rhythms in mania

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

Brain-derived neurotrophic factor is a miracle fertilizer for our brain?

Brain-derived neurotrophic factor (BDNF) is sometimes called “miracle grow for the brain” because several studies have reported that BDNF “nourishes neurons like fertilizer.” It is well-known that BDNF protects brain cells and stimulates growth of their dendrites

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

Males who take citicoline show increased motor speed and attention

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

Keys to unlocking human dopamine D1 receptor signal transduction

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
