The function of Area number 18 and 19 of brain . Why they are called as psychovisual area of brain? Look at this picture first . This mind-blowing optical illusion looks like a classic red Coke can, but here's the kicker: it's actually just black, white, and teal! Our brains are tricked into seeing red due to simultaneous color contrast, where surrounding colors drastically change our perception. When teal and grey are paired in just the right way, our brains interpret them as red, even though there's no actual red light. It's a wild example of how our brains fill in gaps based on context and experience, and it's a pretty cool glimpse into the complexities of color perception. Our eyes detect colors, but our brains do the real interpreting, mixing biology, context, and clever guesswork. This illusion shows just how easily our senses can be fooled, even with everyday things. Next time you think you see something, take another look – your brain might be doing some artistic liberties!

In 2011, an 11-year-old girl in Brazil was diagnosed with extreme hyperdontia confirmed by panoramic X-ray. She had 18 baby teeth, 32 permanent teeth, and an astonishing 31 extra teeth. The non‑syndromic case involved a pericentric inversion on chromosome 9. A team of oral surgeons, orthodontists, periodontists, and prosthodontists staged extractions and orthodontic care to preserve jaw structure and restore normal bite alignment. This remains one of the rarest dental anomalies ever documented.

A rare and unusual case was reported in China, where doctors surgically removed a malformed twin from the brain of a 1-year-old girl.

The little girl had shown signs of developmental delays and had an unusually large head, leading to the discovery. The mass was actually a partially formed twin, with bones like a spine, arms, and even finger-like buds.

This rare condition, known as fetus-in-fetu, happens in about 1 in 500,000 births, where one twin grows inside the other.

Fetus-in-fetu is often mistaken for a type of tumor, but it can be identified by the presence of actual body parts.

While most cases involve the mass growing in the abdomen, it's incredibly rare for it to be found in the brain. Fewer than 200 cases have been documented worldwide, and this adds to the small number of cases where the twin developed in such an unusual location.

The intestine is the most highly regenerative organ in the human body. In fact, it regenerates its lining every 5-7 days.

Here's what to know:

The human intestine replaces its epithelial lining every five to seven days. This rapid renewal is crucial, as the intestine endures constant stress while digesting food, absorbing nutrients, and expelling waste.

A study published in Cell Stem Cell reveals that mature intestinal cells, rather than dormant stem cells, play a surprising role in this process. Researchers discovered that when working stem cells in the intestinal crypts are depleted, mature cells undergo dedifferentiation, transforming back into stem cells to replenish the population.

This finding challenges previous assumptions about intestinal regeneration, which focused on dormant stem cells stepping in during times of need.

Led by Dr. Ramesh Shivdasani of the Harvard Stem Cell Institute, the research deepens our understanding of tissue organization and regeneration. The ability of mature cells to revert to stem cells could have far-reaching implications for regenerative medicine and therapies for intestinal disorders. By unraveling how these processes work at a cellular level, scientists may pave the way for innovative treatments that harness the body’s natural ability to heal.
