Alcohol affects neurotransmitters, which are responsible for feelings and emotions. Genetics, lifestyle, and experiences can influence neurotransmitters and alcohol sensitivity. The four most affected neurotransmitters are dopamine, GABA, endorphins, and glutamate. Alcohol can increase or decrease levels of these substances, causing different reactions in individuals. Neurotransmitters are tiny particles responsible for many feelings and emotions […]
Addictive substances disrupt neurotransmitter brain activity, affecting messages sent between neurons and receptors. Dopamine is a primary neurotransmitter affected by addiction, with drugs like cocaine stimulating or inhibiting dopamine receptors. Chronic drug use impacts brain function and changes the frontal cortex, leading to a lack of concern for consequences. Some drugs are considered more addictive […]
Neurotransmitters, including dopamine, norepinephrine, and serotonin, play a role in regulating mood, pleasure, and sleep. Imbalances in these chemicals can contribute to depression, and multiple neurotransmitters may be involved. Drugs targeting only one neurotransmitter may not be effective for some individuals. Research on the brain, nervous system, and psychological or mood disorders has provided insight […]
Neurotransmitters are chemicals that carry messages between neurons. They are produced in the cell body of a neuron and travel along the axon to vesicles. When a vesicle opens, the neurotransmitter travels across the synapse to receptors on dendrites. There are three main types of neurotransmitters – monoamines, amino acids, and peptides – each with […]
Over 100 neurotransmitters have been identified in the human brain, but there are likely more. The effects of these chemical messengers are not fully understood, making it difficult to develop drugs that target specific cells. Drugs that affect serotonin may not work for everyone with depression, suggesting there are other unidentified messengers. The mechanism and […]
