Chemical signaling between neurons is mediated by neurotransmitters, neuropeptides, hormones, neuromodulators, and many other types of signaling molecules. Many neurological diseases arise due to an imbalance in the brain's neurochemistry. For example, in Parkinson's Disease, there is an imbalance in the brain's level of dopamine.
An antagonist is a chemical that acts within the body to reduce the physiological activity of another chemical substance (such as an opiate); especially one that opposes the action on the nervous system of a drug or a substance occurring naturally in the body by combining with and blocking its nervous receptor.

It also is involved in cognitive processes associated with movement, arousal, executive function, body temperature regulation, and pleasure and reward, and other processes. Norepinephrine , also known as noradrenaline, is a monoamine neurotransmitter that is involved in arousal, pain perception, executive function , body temperature regulation ...
The reason: These vitamins help boost the production of neurotransmitters, or brain chemicals, that deliver messages between the brain and body.. Increasing your B12 by taking a supplement may ...
Here is a list of some of the most important vertebrate brain components, along with a brief description of their functions as currently understood: See also: List of regions in the human brain The medulla , along with the spinal cord, contains many small nuclei involved in a wide variety of sensory and involuntary motor functions such as ...
Information about the structure and function of the human brain comes from a variety of experimental methods, including animals and humans. Information about brain trauma and stroke has provided information about the function of parts of the brain and the effects of brain damage. Neuroimaging is used to visualise the brain and record brain ...
These brain chemicals can lead to feelings of happiness and relaxation. Certain scents may even help reduce anxiety and depression. These include lavender, chamomile, rosemary, and citrus.
