Ramachandran's types of experiments

Wow, Dr. Ramachandran looks a lot different than I imagined him.... Anyways, in his famous book, Phantoms of the Brain, he did this really cool experiment based on the mirror agnosia diagnosis. He called it the "Looking Glass Experiment", named after Lewis Carroll's Through the Looking Glass, sequel of Alice In Wonderland. He made small notes about many great artists and writers who had obsessions with glasses, which could be a result of affections of the right parietal lobe. I guess that saying of Genius is close to Madness might be true.
So, the experiment went like this; he holds a mirror in front of a patient who's right or left visual field suffered damages. Then, he has a helper hold something behind the person, but is visible in the mirror to the viewer aka the patient. He did it with a pen and the neglect patients could not understand that the object they saw in the mirror was behind them. Instead, the patients tried to attack the mirror, looked to their left and right, said that the object was inside the mirror, and etc.
It was extremely weird, but Ramachandran hypothesized that the reason why the patients behaved as they did because of damages to the parietal lobe of the brain. It could affect spatial ability. It was super interesting. I wonder if they use this test at the hospitals now.

Reproduction






Before we began on the reproduction system, I already knew a pretty fair amount from Health and Safety along with 6th grade health classes. But, I learned a bit more in depth from the class.

We went a lot more in depth with the male reproductive organs. The male menopause phrase made me laugh because men also feel symptoms that women get. I still think its totally unfair for women to bleed for 3-5 days while men don't feel any pain. Okay, maybe they do when our hormones go out of wack and we start throwing chairs at them or something. The idea that every period makes me lose 50-150 mL of blood really made me feel sick. That's a lot of blood! I know some cases from friends where they did not stop bleeding. In fact, one girl's period went on for an entire month. She lost so much blood they had to give her a blood transfusion at the hospital!
Also, pregnancy is super scary especially the fertilized egg in the fallopian tubes! I suppose that's why when one is pregnant, they should immediately go to the doctor for a checkup. Also, the three types of sperm cells were funny: The runner, kamakazi, and the blockers. The runner are the ones that swim real fast to the egg, the kamakazi kills unknown sperm cells, and the blockers surround the egg only letting their own people fertilize the egg. Wow, men are pretty possesive, hahah.

Urine testing's great diagnostics





Peeing in a cup for medical examination is a lot easier than having blood sucked out from our veins, grimacing at our life's liquid flowing into a tiny tube. So, why not use wastes to identify our internal problems?

Introducing (Drumroll) URINE!!

Different colors mean different diagnosis.

If there is a redness, caused by blood, you have BLADDER INFECTION.

Orange or brown indicates Jaundice or Gilbert's syndrome.

Light orange - lack of vitamin B, so go buy bottles and bottles of vit. B pills

A Pinkish tint- possibly from eating too much watermelon. Usually harmless.

Black/really dark colored tint - Melanoma. A BIG indicator!! Black urine is very very dangerous!

Clear Urine - healthy urine

Reddish brown urine - poryphyria

Dark Yellow - dehydration

Fluroescent yellow/ green - too much vitamins.

Who knew urine had THAT many colors?

well, now you know. :D
