Brain Perceives facts

While investigating facts about Brain Perceives Pain and Brain Perceives Motion, I found out little known, but curios details like:

Most volume knobs must operate on a logarithmic curve, not a linear one, because the human brain perceives differences in small volumes far better than it can tell differences in large volumes

how brain perceives color?

People with anxiety perceive the world differently-their brain lumps both safe and unsafe things together and labels them all unsafe.

What part of the brain perceives color?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what part of the brain perceives time. Here are 24 of the best facts about Brain Perceives Color and Brain Perceives As Sound I managed to collect.

what part of the brain perceives pain?

1. Motion sickness is due to confusion between perceived movement and actual movement. The brain's conclusion is that one of the senses is hallucinating due to poison ingestion; the brain then induces vomiting to clear the supposed toxin.

2. The human brain doesn't perceive total blackness when there is no light present; it instead perceives Eigengrau, a shade of dark gray, because contrast is more important to the visual system than absolute brightness

3. Time doesn't actually (even perceivably) appear to slow down during life threatening situations - the brain simply makes more dense and detailed memories of the event which makes it seem in retrospect to have lasted longer.

4. Szechuan peppers make your lips/tongue numb, not hot. Its not the capsaicin (found in pepper that interacts with heat receptors so we perceive spicy). Instead, its hydroxy-alpha-sanshool interacting with tactile receptors (thus your brain perceives vibrating / electrocution style sensation).

5. Self-injury works to reduce emotional pain because of a phenomenon called pain offset relief. "This may be because the physical pain relief that follows a self-injury event basically tricks the brain into perceiving relief of emotional pain too!"

6. Bruce Bridgeman, a professor of psychology, lived 67 years stereoblind - unable to perceive depth. However, watching a 3D movie caused some changes in brain's vision centre that enabled to experience stereoscopic three dimensional vision.

7. A single fold in the brain makes the difference between perceiving reality and fantasy.

8. The McCollough effect, a pair of images that, if stared at long enough, will alter the way your brain perceives colors for up to 3 months!

9. Humans have a blind spot in our vision that our brain interpolates the blind spot based on surrounding detail and information from the other eye, so we do not normally perceive the blind spot.

10. Soviet leader Joseph Stalin had a secret laboratory in which he and other scientists analyzed the stool samples of Mao Zedong and other perceived "enemies" to understand the inner-workings of their brains.

Why causes brain injury?

You can easily fact check why the brain injury by examining the linked well-known sources.

When the auditory component of one sound is paired with the visual component of another sound our brains will perceive a third sound in an auditory illusion called the McGurk effect

The cerebral cortex (the top brain layer with the folds), where all our complex thinking, perceiving, producing and understanding language happens, is only 2 mm (0.08 inch) thick. It's 48x48 cm sheet of 2 mm thickness - source

Blindsight is a phenomenon in which people who are blind due to certain types of brain damage will still respond to visible stimuli that they cannot consciously perceive. - source

Low Latent Inhibition, a condition which causes the brain to treat familiar stimuli in the same manner as it would new stimuli. This can make it very difficult for someone with LLI to focus as they perceive every minute detail as if it was their first time experiencing it.

Albert Einstein's brain was removed at his autopsy without his family's permission and sent to a lab for testing for "perceived secrets". - source

Occurs when the brain notices and interprets a sensation?

Our brain perceives a sound emitted by an instrument to be twice as louder if 10 instruments are playing instead of 2.

How brain perceives time?

About the Ames illusion, which makes your brain perceive two SAME height objects as two objects with very DIFFERENT heights!

The Ganzfeld Effect describes the effects induced by perceptual deprivation rather than sensory deprivation. A constant uniform stimulus is used instead of attempting to remove the stimuli; this leads to a perceived loss of vision as the brain cuts off the unchanging signal from the eyes.

Marketers put middle priced “decoy” products that are slightly less expensive than the most expensive item (think medium size). This method tricks your brain into perceiving more value and is called “the decoy effect.”

Conservatives' brains are dominated by fear, have greater anxiety in response to perceived threats, and fear new experiences.

The neurological basis for racism, how one's brain responds differently towards those it perceives as part of an "outgroup," and that this response can be rewired.
