Explanations on a very simple phenon

In summary, the pineal gland, also known as the "3rd eye", is a light-receptor in lower vertebrates and plays a role in regulating the circadian cycle of sleep in humans. It is linked to the optic chiasm and receives signals from the eyes. The production of serotonin by the pineal gland is essential for the production of melatonin, a hormone that helps us sleep. It has been suggested that LSD affects the pineal gland, as it is a serotonin antagonist.

How can you explain biologically why we are sleepy ? I find even people who have normal sleep order also feel sleepy often...

sleep is an interesting thing...there is an organ deep in the brain called the pineal gland, the ancients called it the "3rd eye", and in lower vertebrate it actually is a functioning light-receptor (by passing light through an opening). Our no longer receives light directly, and has migrated deep in the brain near the hypothalmus. In humans it is linked in the optic chiasm and receives signals from the eyes. It has been determined that the circadian cycle of sleep is determined by this gland and it's production of serotonin.

It is also believed that LSD acts directly on cells of this organ. Descartes called it the "seat of consciousness".

Melatonin.

Melatonin.

the pineal makes serotonin, then serotonin gets made into melatonin which then gets released from the pineal gland. the pineal can make an overproduction of serotonin, which does not get converted into melatonin.

LSD is a serotonin antagonist.
 

What is a simple phenomenon?

A simple phenomenon is a basic and easily observable event or occurrence in the natural world that can be explained through scientific principles and laws.

Why is it important to explain simple phenomena?

Explaining simple phenomena helps us to better understand the world around us and can lead to further discoveries and advancements in science and technology.

What are some examples of simple phenomena?

Examples of simple phenomena include gravity, magnetism, the water cycle, photosynthesis, and the formation of rainbows.

How do scientists explain simple phenomena?

Scientists use the scientific method, which involves making observations, forming hypotheses, conducting experiments, and analyzing data, to explain simple phenomena.

Can simple phenomena also be complex?

Yes, simple phenomena can also have complex underlying mechanisms and interactions. For example, while gravity is a simple phenomenon, the concept of gravity is complex and has many layers of explanation.
