The organization of the brain reveals the architecture of the mind

Ikrrrr?

Totally, prof. Nancy Kanwisher once said:
The fundamental reason the brain is cool is that it gives rise to the mind. Studying the biological properties of the brain without considering the mental functions it implements would be like studying the physical properties of a book without considering the meaning of its text.

Mittelschmerz (middle pain)

It's a benign preovulatory lower abdominal pain that occurs midcycle (between days 7 and 24) in women. 
It's called ovulation pain because it occurs really close to (before) ovulation, which is also why it's called middle pain (Mittelschmerz) since it occurs midcycle.

most often presents as an acute lower quadrant (usually right-sided) pain ranging from a mild ache to intense pain, and it can be confused with acute appendicitis.

Rovsing’s sign : right lower abdominal quadrant pain elicited by pressure applied on left lower quadrant.

In the case of appendicitis, the appendix is clogged and distended. In time, a full-thickness inflammation of the wall will develop that will irritate the peritoneum.

The purpose of applying pressure in the left lower quadrant is double,
- This maneuver pushes intestinal content from the left lower abdomen in an antiperistaltic fashion, increasing pressure in the colon and thus the appendix, and further irritating the peritoneum eliciting tenderness at the site of inflammation.
- The pressure is far away from the expected location of the pain, and the indirect tenderness suggests a less biased (more objective) localization of the pain.

The predictive power of Rovsing’s sign (indirect tenderness) is much greater than that of the even more generally known McBurney’s point tenderness (direct tenderness).
