Romantic love can make your nerves grow, provided you do not give the feeling longer than one year, reports Wikipedia.
Recent studies found that the concentration of the nerve growth factor (NGF) in the blood plasma is significantly higher in individuals that have been in a romantic relationship with another person for less than 12 months.
The news has come with Psychoneuroendocrinology, a journal to join neurology, endocrinology, and psychology, that is, the neuron, the gland, and a sort of ego.
In view of the complexity of a sentiment like love, it would not be surprising that a diversity of biochemical mechanisms could be involved in the mood changes of the initial stage of a romance, says the journal.
The journal shows the NGF factor in (a) people to have just fallen in love, (b) those in a long-lasting relationship, and (c) for singles.
We do not have to be specialists, to put the numbers from the biggest to the smallest.
a. 227 (14) pg/ml;
c. 149 (12) pg/ml.
b. 123 (10) pg/ml;
If nerve growth is a good thing, a long-lasting relationship is the worst circumstance for it.
A lasting, mutual, and fond affair cannot be the worst circumstance for love. Let us see what NGF does.
NGF can indirectly stimulate the expression of adrenocorticotrophic hormone (ACTH), by increasing vasopressin secretion, continues Wikipedia.
For long and scientific words as adrenocorticotrophic, we can copy them and paste into Merriam-Webster online.
The dictionary says something adreno•cortico•tropic is something that acts on or stimulates the adrenal cortex.

For human anatomy, we may get by simply looking up what a part does. An adrenal gland produces the hormone epinephrine.
MERRIAM-WEBSTER DEFINITION FOR KIDS
Is this thing about love?
Epinephrine is a stress hormone.
The hormone is part of the body’s fight-or-flight response to stress, as when someone is in a dangerous, frightening, or highly competitive situation, EXPLAINS MERRIAM-WEBSTER.
We can browse online. Epinephrine has been suspected in “voodoo deaths”.
The “psychogenic” or “psychosomatic” deaths were noted regardless of culture or geography, in camps, concentration and prisoner-of-war.
The idea to “blame the soul” when bodily causes are not clear may persist, yet it looks quite obvious the “psychogenic” death is actually an epinephrine death.
Excess epinephrine — or adrenaline, the name cannot be a factor — kills. Could a stress hormone account for romantic love?
Cortisol could not occasion love poetry. Linguistic endeavors altogether favor the brain happy for good memory function, and cortisol memories are “flash-bulb”: mostly visual and fragmentary. Cortisol high levels inhibit memory.

For vasopressin, it is actually homeostatic, and it can work in remembering, as well as forgetting. It is part in keeping bodily levels for sodium as from kitchen salt (Vander et al., Human Neurophysiology, 1985).
The LVP (lysine vasopressin) and placebo groups showed an enhancement; we yet cannot claim a memory enhancing effect of LVP, because placebo treatment enhanced memory performance to the same extent, say researchers, where saline was the placebo. 😉

With the pinch of salt, comes the most important aspect of human brain function: the graded and action potential.
By the way, why grow nerves for love?
A nerve is an enclosed, cable-like bundle of axons (nerve fibers, the long and slender projections of neurons) in the peripheral nervous system.
In the central nervous system, neurons are sometimes called nerve cells, though this term is potentially misleading, since many neurons do not form nerves, says Wikipedia absolutely correctly.
Before we get embarrassed about some potential implications a dictionary for kids might not have, let us think what really happened, with the Psychoneuroendocrinology research.
Blood samples were taken from people whose lifestyles varied on muscular activity.
Those in love were the most outgoing, and settled within more or less 12 months. Those in long-term relationships shared everyday duties, and spent more time relaxing together. Those living single did not have a partner or spouse to partake in the household.
For love of good nerves, fortunately there is physical exercise. 🙂
