We surely were amazed often to see a few patients lying conscious on the operation table with their heads open. Such surgeries were possible only because of the lack of pain receptors in the brain. This makes it possible for the surgeons to operate on the brain without the patient feeling a thing. Kind of a eureka!

  1. Size of the brain

We see that infants seem to have bigger heads in proportion to their bodies. It certainly makes them look cute as well as funny. The main reason behind this is the fact that they already have fully grown brains. This is why their skulls look bigger. As and when they grow, the size of their brain remains constant.

  1. Thoughts

We have innumerable thoughts everyday, or perhaps every other moment. Ever tried counting the number of those thoughts?  You certainly would lose the track of the number.

  1. 100,000 miles of axons

This might come as a very shocking surprise but it is true. There are about 100,000 miles of axons in our brain. If connected together, these have the capacity to wrap the Earth nearly four times! For those still wondering what an axon is, it is nothing but a long projection of the nerve fibre. It is responsible for transmitting information from one neuron to another.

  1. More active during sleep

Brain is far more active during our sleeping hours than our waking hours. This would be clearer with the help of an instance. We have dreams and thoughts every night. Occasionally they reflect the happenings of our day. This definitely is high level activity of the brain which plays out our daily actions in our dreams. Often some dreams are pretty metaphorical. Dreams, so far have been one of the most intriguing aspects in the world of neurological sciences.

  1. Stores 1 quadrillion pieces of information

Human brain is a powerful store house of information. When we talk of information, it implies all the bits and pieces of facts and knowledge that we ever come across in our lives. Nothing that we experience ever skips our brain. It may simply shift from level of consciousness from another. All that is needed to bring about the tiniest of repressed information is a therapy.

Human brain develops till the age of 40. It is not about the size, but of the cognitive skills and functions that it performs. While the size of the brain of a two year old gets fairly stable, its capacity to perform intricate functions simply develops. By the time, you reach your 40’s most of the functions of the brain are likely to have reached at its peak.

  1. Fast processesor

Our brain processes information at an unbelievably high speed of 260 miles per hour. This is the reason why we are able to respond to stimuli in a fraction of seconds. All our reflex actions depend on this high speed of processing.

The best example that can be taken into consideration can be that of Albert Einstein whose brain was 10% smaller than the average size.

  1. Multitasking is bad for brain

Many hold the ability to multitask as a virtue. But your brains would not agree to it. Multitasking very often causes the brain to switch from one task to another every instant. If carried on for long, this may lead to affected attention span and short-term memory. Refrain from making it a habit.
