Endorphins: The Feel Good Neurotransmitters
Endorphins, often referred to as the “feel good” neurotransmitters, play a crucial role in our overall well-being. One prominent example of their effect can be observed during exercise. When we engage in physical activity, our bodies release endorphins, resulting in a boost of positive emotions. Remarkably, endorphins function similarly to certain painkillers by interacting with the brain’s protein-coupled opioid receptors, effectively reducing the perception of soreness or pain.
GABA: The Inhibitory Neurotransmitter
Gamma-aminobutyric acid (GABA) is a crucial neurotransmitter responsible for various functions within the body, such as vision, muscle control, and anxiety regulation. One of its primary roles is helping us see in low-light conditions by regulating light sensitivity through specific forms of GABA. In the case of Huntington’s disease, a fatal hereditary condition characterized by the death of brain cells, the lack of coordination often experienced can be attributed, in part, to the loss of GABA, as well as acetylcholine and glutamate. Additionally, studies have shown that individuals with very low levels of GABA may be more prone to increased anxiety, highlighting the importance of this neurotransmitter in mental health.
