In our day-to-day lives, we're constantly making a slew of decisions, from immediate matters to prospects on the far horizon. But the evolutionary nuts-and-bolts of how our brains weigh these numerous ...
The role of serotonin in human behaviour is informed by approaches which allow in vivo modification of synaptic serotonin. However, characterising the effects of increased serotonin signalling in ...
Serotonin is a chemical produced mostly in our digestive tract. 1 Despite its humble beginnings in the gut, serotonin has the important job of deciding which brain cells to "turn off" (inhibit) during ...
Low levels of serotonin in the brain are seen as a possible cause of depression and many antidepressants act by blocking a protein that transports serotonin away from the nerve cells. A brain imaging ...
Years before someone with Parkinson's disease has any movement-related symptoms, slight malfunctions of the brain's serotonin system could be an early warning sign that the roots of PD are taking hold ...
In a recent study in Nature Communications, researchers increased synaptic serotonin through a selective serotonin-releasing agent (SSRA), fenfluramine, to investigate its impact on human behavior.
Serotonin is a neurotransmitter important for mood, digestion, and sleep. You can increase serotonin levels naturally through exercise and sunlight. Serotonin is a naturally occurring monoamine ...
The intestine hosts the largest immune system and peripheral nervous system in the human body. The gut‒brain axis orchestrates communication between the central and enteric nervous systems, playing a ...
Researchers at Case Western Reserve University School of Medicine have created the first complete model to describe the role that serotonin plays in brain development and structure. Serotonin, also ...
Dopamine and serotonin are both neurotransmitters — chemical messengers that transmit signals between cells — which regulate bodily functions like mood, sleep, and digestion. While dopamine and ...
Loss of the "happiness" brain hormone serotonin might play a role in the decline of brain function as a person ages, a new study reports. People with mild cognitive impairment (MCI) had up to 25% ...
Low levels of serotonin in the brain are seen as a possible cause of depression and many antidepressants act by blocking a protein that transports serotonin away from the nerve cells. A brain imaging ...
