High Dopamine Levels in Women May Be Tied to Procrastination

The researchers studied the genotype of 278 females and men. They were particularly curious about what is referred to as the tyrosine hydroxylase gene (TH genetics).

Relying on the expression of the gene, people’s brains include differing amounts of natural chemicals from the catecholamine family members, to which the natural chemical dopamine belongs, together with epinephrine (adrenaline) and norepinephrine (noradrenaline).

A new German study discovers that women with a genetic tendency for greater dopamine levels in the brain might be more probable to participate in dalliance behaviors. No such link was discovered in males.

” The natural chemical dopamine has repeatedly been related to raised cognitive adaptability in the past,” claims Dr. Erhan Genç from the Ruhr-University Bochum Department of Biopsychology. “This is not fundamentally negative but is commonly gone along with by raised distractibility.”

The searchings for are released in the journal Social Cognitive and also Affective Neuroscience.

The team likewise made use of a questionnaire to tape-record exactly how well the individuals had the ability to regulate their actions. They discovered that females with poorer action control had a hereditary predisposition towards higher dopamine levels.

Whether an individual often tends to postpone jobs or tackle them as soon as possible depends on his/her ability to maintain a specific purpose to act without being distracted by conflicting aspects. Dopamine could be vital right here. In previous researches, dopamine has not just been related to raised cognitive flexibility, however it additionally seems to make it much easier for info to go into the working memory.

” We think that this makes it more difficult to maintain a distinct intention to act,” says doctoral prospect Caroline Schlüter. “Women with a higher dopamine degree as a result of their genotype may tend to delay actions because they are extra sidetracked by ecological as well as other elements.”

Previous research study has likewise shown gender-specific differences between the expression of the TH genetics and behavior.

” The relationship is not yet understood totally, yet the female sex hormone oestrogen appears to contribute,” says Genç. Estrogen indirectly affects dopamine production in the mind and enhances the variety of particular neurons that reply to signals from the dopamine system.

” Women might therefore be more susceptible to genetic distinctions in dopamine degrees because of oestrogen, which, consequently, is reflected in practices,” says the biopsychologist.

Next, the team plans to study to what degree estrogen degrees really influence the relationship in between the TH genetics and also action control. “This would certainly require taking a better look at the menstrual cycle and the associated variations in the participants’ oestrogen levels,” says Schlüter.

In addition to dopamine, the TH genetics likewise influences norepinephrine, an additional vital natural chemical from the catecholamine family members. The researchers aim to take a look at the role that these 2 neurotransmitters play at work control in refresher courses.
