Over half the neurons in your brain only have four inputs.
Brain information travels up to an impressive 268 miles per hour (431 kilometres per hour).
Your brain isnt fully formed until age 25.
Elephants have the largest brains of all terrestrial mammals.
Adult zebrafish can regenerate their spinal cord.
The typical brain comprises about 2% of the body´s total weight, but uses 20% of its total energy and oxygen intake.
Neuroscientists can read a rat´s imagination.
Your brain generates about 12-25 watts of electricity. This is enough to power a low wattage LED light bulb.
There are 86 billion neurons in the brain.
There are more than 125 trillion synapses just in the cerebral cortex alone.
Being dehydrated by just 2% impairs performance in tasks that require attention, psychomotor, and immediate memory skills, as well as assessment of the subjective sta
As little as five minutes without oxygen can cause some brain cells to die, leading to severe brain damage.
Your brain can process an image that your eyes have seen for as little as 13 milliseconds – less time than it takes for you to blink.
The sperm whale has the biggest brain of any animal species, weighing up to 20 pounds (7 to 9 kilograms).
A piece of brain tissue the size of a grain of sand contains 100,000 neurons.
The spinal cord is the highway for communication between the body and the brain.
As little as five minutes without oxygen can lead to severe brain damage.
Every minute, 750-1000 milliliters of blood flows through the brain.
Neanderthal brains were 10% larger than our Homo sapiens brains.
Albert Einstein s brain weighed 2.71 pounds (1,230 grams) – 10% smaller than the average of 3 pounds (1,360 grams). However, the neuron density of his brain was greater than average.
There are three types of neurons based on their function- interneurons, sensory and motor neurons.
The outer region of the hemispheres, the cerebral cortex, is the grey matter formed by the cortical layers of neurons.
The cerebellum plays an important role in motor control.
More than 100,000 chemical reactions take place in the brain every second.
Working with mice, researchers in 2016 at Johns Hopkins University have contributed significant new evidence to suport the idea that high doses of cocaine kill brain cells.
Celebral spinal fluid flows in and around the hollow spaces of the brain and spinal cord.
There is a great deal of neural conversation between the gut and the brain. After all, if the gut is not well fed, it could be a matter of life and death; the brain needs to be informed when energy i s low so that it can call other systems into action.
Each neuron is capable transmitting as many as 1,000 nerve impulses a second.
The average human brain size have decreased over 10% in the past 10,000-20,000 years.
In 1931 Theodore Erismann experimented with goggles which flips vision. At first person struggles with the flipped perception, but after just few days the brain will adapt to it.
