The pineal gland — which regulates the cycles of sleep and waking — appears to have evolved as an indirect way to improve vision, by keeping toxic compounds away from the eye, according to a new ...

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 ...

Zebrafish larvae without eyes or pineal glands can still respond to light using photopigments located deep within their brains. Published today (September 20) in Current Biology, the findings are the ...

The concept of decalcifying the pineal gland is an alternative practice. Practitioners believe by reducing calcifications on the pineal gland, you’re less likely to have medical conditions, such as ...

Your brain contains a small pine cone-shaped gland called the pineal gland. It’s about the size of a grain of rice. However, that size can vary in animals depending on their location. ‌This tiny gland ...

The pineal gland is a small gland in the center of the brain. It secretes melatonin, which plays a role in the circadian rhythms or body clock. It may also affect bone metabolism, mental health, and ...

The pineal gland, a reddish-gray, pine cone-shaped part of the brain, is unremarkable at first glance: It’s about a third of an inch long and tucked deep in the brain, near the center and between both ...

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, ...
