Though the pineal gland wasn’t understood until the 20th century, descriptions of its anatomical location are included in the writings of Galen (ca. 130-ca. 210 CE), a Greek doctor and philosopher.

The function of this small organ near the center of the mammalian brain has long been a mystery. Recent studies indicate that it is a "biological clock" that regulates the activity of the sex glands ...

Zebrafish are known to detect color and brightness with the pineal gland, which is part of the brain. How they do so is now being elucidated. We see color because photoreceptor cones in our eyes ...

Many non-mammalian vertebrates like fish, however, are known to detect color and brightness with the pineal gland, which is part of the brain. An Osaka Metropolitan University research group has ...

It stands to reason that the pineal gland has an important role in this ... This is our biological clock and the central location for the “on-off” switch of melatonin synthesis—rather ...

Researchers have elucidated how a single photoreceptor in the pineal gland of zebrafish detects color. We see color because photoreceptor cones in our eyes detect light waves corresponding to red ...
