A Brief Background of Dopamine

A Brief Background of Dopamine

This neurotransmitter is affected by Daxitrol, AdreCor, Balance D, and ExcitaPlus

Ever wonder why you suddenly feel happy and rewarded after munching on large fries and burger to satisfy your cravings or why you feel happy and motivated to suddenly run in a marathon? That may be due to a neurohormone slash neurotransmitter known as dopamine.

 

For those who are new to these terms, a neurotransmitter is a chemical signaling molecule produced in the brain. When a neurotransmitter is released into the junction where two cells in the brain meet or a synapse, it crosses the gap and holds to the receptors intended for it. These receptors then get activated to make a further action or to stop signaling. Dopamine as a neurotransmitter is produced by the substantia negra in the midbrain section. Important to note here is that the substantia negra is one of the major players affecting the body’s movement making this hormone infamous to being linked with Parkinson’s disease.

 

Another brain area of concern in relation to dopamine is the Ventral Tegmental Area. This neurotransmitter increases when we encounter things that we find to be pleasurable or rewarding such as designer bags and shoes for shopaholics. Dopamine level changes are thought of to be linked with addiction because of this property.

 

Dopamine does not only act as a neurotransmitter in the body but also as a hormone, just like in the case of epinephrine and norepinephrine. Dopamine has its main effects in the hypothalamus where it inhibits the secretion of prolactin from the anterior lobe of the pituitary. Prolactin, which is another hormone, is responsible for regulating lactation and orgasms. 

 

With the many effects seen in the body by this chemical, dopamine can be supplied as a drug medication that increases heart rate and blood pressure like norepinephrine. Dopamine also works in complementary with other neurotransmitters such as acetylcholine.
