Other neurochemicals and their influence on mood

In addition to the more well-known neurotransmitters such as serotonin, noradrenaline, dopamine and oxytocin, there are other chemicals in the brain and body that also play a role, although sometimes more specific, in regulating mood, energy levels and cognitive functions.

Understanding their influence, even in a general way, helps to complete the picture of the neurochemistry of well-being.

Substances Associated with Stress and Pain

There are neurotransmitters or neuromodulators that, when imbalanced or released in excess, can contribute to the experience of stress and the perception of acute pain.

Hormones such as cortisol (the "stress hormone") and certain neuropeptides are known to be involved in these responses.

An imbalance in these systems can negatively affect mood and overall sense of well-being.

Adenosine. Fatigue Regulator

Adenosine is a neurotransmitter that accumulates in the brain during the day and is involved in promoting sleep and feelings of fatigue.

As its levels increase, it can induce a feeling of mental and cerebral fatigue, known as "mental override".

Although this process is natural and necessary to regulate the sleep-wake cycle, an imbalance or excessive accumulation during the day can negatively affect mood, well-being and the ability to feel alert and happy.

Acetylcholine. Implicated in Memory and Sleep.

Acetylcholine is another crucial neurotransmitter with multiple functions. It plays an important role in memory and learning, facilitat
