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.
Neurotrophic factors are biomolecules – nearly all of which are peptides or small proteins – that support the growth, survival, and differentiation of both developing and mature neurons. [2] [3] [4] Examples of notable neurotrophic factors include: Insulin-like growth factor-1 (IGF-1) Glial cell line-derived neurotrophic factor (GDNF)
The following is a list of hormones found in Homo sapiens. Spelling is not uniform for many hormones. Spelling is not uniform for many hormones. For example, current North American and international usage uses [ citation needed ] estrogen and gonadotropin, while British usage retains the Greek digraph in oestrogen and favours the earlier ...
This is done through reducing or blocking signals to the conscious mind from other parts of the brain. Although many kinds of drugs are capable of such action, dissociatives are unique in that they do so in such a way that they produce hallucinogenic effects, which may include sensory deprivation, dissociation, hallucinations, and dream-like ...
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.

Forever chemicals can be found in tap water, including in South Florida. PFAS have tainted oysters in Biscayne Bay. High levels of these man-made chemicals pushed Miami-Dade to shut down three ...
Fast fashion is made with alarmingly high amounts of toxic chemicals, say authorities. 5 substances can affect your immune system. Meghan Morris,Allana Akhtar November 28, 2024 at 12:39 AM
Neuropeptide Y. Neuropeptides are chemical messengers made up of small chains of amino acids that are synthesized and released by neurons.Neuropeptides typically bind to G protein-coupled receptors (GPCRs) to modulate neural activity and other tissues like the gut, muscles, and heart.
