Spending just a few months in Antartica can shrink your brain due to environmental monotony and prolonged isolation.
A brain syndrome called mirrored touch synaesthesia causes people to physically feel what other people are feeling just by looking at them. For example, a person can look at a dog and fee fur texture on his palms, this is an involuntary response. Brain automatically fills in what it thinks the dog feels like without needing to touch it. Sometimes people also have mirror-taste, so they can look at something and “taste” it in their mouth.
A married father in France went to the hospital complaining of a 2 week history of mild leg weakness, only to find out he lived his whole life with 90% of his brain missing.
Researchers discovered that applying a sonogram to a person’s skull and stimulating specific brain regions can alter their mood. One researcher described applying it to his own head and later feeling like he had a martini. They hope to develop a sonogram-based device to treat mood disorders.
Psychologist George Stratton wore glasses that turned the world upside down for 8 days. By the third day his brain had adjusted the image to feel right side up and normal. Once he took the glasses off his normal vision looked inverted for hours.
The brain shields us from existential fear by categorising death as an unfortunate event that only befalls other people.
Scientists scanned the brains of lifelong bullies and found that they are physically small.
A brain injury sustained during a mugging turned a man who used to think “math is stupid” into a mathematical savant with a form of synaesthesia that lets him see the world in fractals.
Einstein was born missing part of the brain that influences speech and did not speak until the age of three. However, his parietal lobe, responsible for math and spatial recognition, was abnormally large.
Science Alert claims this illusions mimics time travel in the brain:
In the Illusory Rabbit, the middle flash never happens, but most people still think they saw three flashes to match three beeps.
In the Invisible Rabbit, it’s the middle beep that is missed – and the brain usually thinks there was no middle flash either.
The fact that the middle beep or flash IS getting manipulated shows postdiction at work – it’s actually the last flash and beep that causes the illusion to happen. They make our brain alter what it perceived in the past.
