___________, a hunger-stimulating hormone, is secreted by specialized cells in the stomach.
Inga [223]

Ghrelin is a hunger-stimulating hormone which is secreted by specialized cells in the stomach.

Ghrelin is a hormone made in the intestine. It is often called the "hunger hormone" and is sometimes called lenomorelin.

It reaches the brain through the bloodstream and tells the brain to feel hungry and start looking for food.

It's main function is to increase appetite. Eat more food, take in more calories and store fat.

In addition, it affects the sleep-wake cycle, reward-seeking behavior, taste sensation, and carbohydrate metabolism.

This hormone is made in the stomach and is secreted when the stomach is empty. It enters the bloodstream and affects a part of the brain called the hypothalamus, helping regulate hormones and appetite. Lower levels make you feel fuller and easier to cut calories.

When a monkey grasps, holds, or tears something, mirror neurons fire. and they likewise fire when the monkey observes another do
Ierofanga [76]

Mirror neurons fire demonstrates the ability of primates to empathize with another organism.

Mirror neurons are a class of neurons that modulate their activity both when an individual executes a specific motor act and when they observe the same or similar act performed by another individual.

Recent studies have shown that the mirror neurons have been hailed as a cornerstone of human empathy, language, and other vital processes.

These neurons are initially found as motor command neurons present in the frontal lobes of the brain and the prefrontal areas of the brain.

These are neurons which fire when a person moves and these are regular motor command neurons, orchestrating a sequence of muscles that allow the person to move something or do some other action.

A subset of these neurons also fire when that person simply watches another person move and do exactly the same action. So these neurons are performing a virtual reality simulation in the brain.

Another example of this is phantom limb.
