I would like to share some unknown interesting secrets about your brain you probably didn’t realize you had:
Most Interesting Things About Brain
You have two nervous systems:
One set controls excitation and the other controls inhibition. If you hold out your hand, you might notice minor tremors. This is caused by slight, random differences in the amount each of the two systems are firing.
Long-term memory shuts down during sleep
The parts of the brain that transfer information to long-term memory shut down while sleeping. This is why dreams quickly fade away after you wake up. Although you may have several dreams in a night, they aren’t being recorded into long-term memory. Generally only the fragments of a dream left in short-term memory have a chance to be encoded after you wake up.
Your memory isn’t great either:
Studies have shown that people are highly likely to misremember past events. Even worse, it is incredibly easy to suggest a memory that never happened. This is why so-called “repressed” memories should be given a lot of thought. It is far easier to suggest a memory of an event never happened, then it is to recover one that actually did.
Your short-term memory has a max capacity of seven:
Humans have three forms of memory: sensory, long-term and short-term. Long-term memory is like hard-drive space, while short-term memory works like a very small RAM. This short-term memory can hold only about five to nine (average is seven) items at a time.
Remembering information longer than this requires you to either compress it down into seven units or store it in long-term memory. Most phone numbers are only seven digits.
Your subconscious is smarter than you are:
Or at least more powerful. In one study, a square was assigned to a location on a computer screen through a complex pattern. After watching it, people began to get results better than chance of picking out where the square would pop up next. But when asked to consciously determine the pattern, even given a few hours, nobody could do it.
