Why Reading In The Car Makes You Carsick

Nearly 80% of the general population experiences motion sickness at some point in their life. That's because although humans have changed in many ways over our evolutionary history, our brains still need to catch up to modern travel methods.

That sickly feeling you get reading in a moving vehicle all starts with your thalamus. It's the job of the thalamus to interpret all the sensory signals the body sends its way. In everyday life, those sensory signals come from your muscles as you move, your eyes as you observe what's going on around you, and even your inner ear, which contains balance sensors that tell you which way is up and how much you're moving. But when you're reading in a car, your muscles and eyes tell your thalamus that you're sitting still while your inner ear says that you're in motion (because inner ear can detect linear/angular accelaration and deccelaration).

This mismatch is what causes the unpleasant feeling. Your brain may not understand modern transport, but it does understand that contradictory signals can be caused by poison, so it reacts as if that's the case. What happens when you're being poisoned? Dizziness, nausea, and possibly vomit. However, the effects are different for different people. Some can handle cars and trains, but not boat rides. Others are fine in the backseat, but they must look out the window. This action can help their brains reconcile that they're indeed moving by taking in external information.

If you've never experienced motion sickness, consider yourself well adapted.

- ALICE IN WONDERLAND SYNDROME-

Imagine this...

You're hallucinating......., and you know it. Time is messed up. First it seems slowed, then it seems to be speeding up. Even more noticeably, when you look at your body, it seems to be morphing. You're getting smaller. Minutes later, you're growing larger and larger.

Alice-in-Wonderland syndrome (AIWS, named after the novel written by Lewis Carroll), also known as Todd's syndrome or lilliputian hallucinations, is a disorienting neurological condition that affects human perception. Sufferers may experience micropsia, macropsia, or size distortion of other sensory modalities. A temporary condition, it is often associated with migraines, brain tumors, and the use of psychoactive drugs. It can also present as the initial sign of the Epstein-Barr Virus . Anecdotal reports suggest that the symptoms of AIWS are fairly common in childhood, with many people growing out of them in their teens. It appears that AIWS is also a common experience at sleep onset. Alice in Wonderland Syndrome can be caused by abnormal amounts of electrical activity causing abnormal blood flow in the parts of the brain that process visual perception and texture.
Carroll’s diary reveals that in 1856 he consulted William Bowman, an eminent ophthalmologist about the visual manifestations of migraine he regularly experienced. Since Lewis Carroll suffered from these symptoms of migraine years before writing Alice’s Adventures in Wonderland, it is reasonable to presume that Carroll used his experiences as inspiration.

Alice in Wonderland Syndrome (micropsia and macropsia) is experienced after ingestion of muscimol. The famous hallucinogenic that Alice from Alice in Wonderland eats ("red and white toadstool") is Amanita muscaria or Fly Agaric, which contains the psychoactive alkaloid muscimol.

The Man Who Can't Get Fat-


Mr Perry, 59, can eat whatever he likes - including unlimited pies, burgers and desserts - and never get fat. He cannot put on weight because of a condition called lipodystrophy that makes his body rapidly burn fat.

He used to be a chubby child, but at age 12 the fat dropped off "almost over night". He initially tried to eat more to gain weight, but it had no effect. Mr Perry, of Ilford in Essex, endured a decade of tests before the illness was diagnosed. It finally emerged that his body produces six times the normal level of insulin. Doctors have admitted that the condition would be a "slimmer's dream".

Cotard delusion-
Is there anything stranger than an otherwise-sane person wholeheartedly believing he or she is dead? Cotard delusion, otherwise known as walking co**se syndrome, is an extremely rare condition whereby people wake up one day and think they have died, that they no longer exist, or that their flesh is rotting off. It's all in their head, of course, but there's a physical cause nonetheless: The brain region involved in facial recognition has become disconnected from the regions involved in emotion. When the person looks in the mirror, they recognize themselves, but they don't have the usual emotional response. Their appearance has lost its association with their sense of self, and this cognitive dissonance results in the sense that they do not exist, or have died.
