Your efficient, calm brain

It weighs around 1.5 kg, which is only about 2% of the total weight of the human body, but it controls the activity of all our bodily functions. It is the author of our memories, dreams and emotions. It determines who we are. The brain.

A human is born with around a hundred billion neurons. Every day from birth, we lose about 100,000 of them. The death of neurons (apoptosis) is necessary due to their excess. There are hundreds or even thousands of synapses on each neuron, making up 13 trillion connections. During human development, there is a reduction in synaptic connections - this, too, is the result of overproduction and the need for elimination. (…) Despite this reduction, according to Nobel laureate Gerald Edelman, it would take 32 million years to count all connections in the central nervous system.” (Jolanta Panasiuk, Learning and Mechanisms of Neuroplasticity)

The amazing brain

Reading about the brain is like reading poetry to me, just it’s also practical, apart from being beautiful. The number of difficult words is around the same and all of a sudden, I’m transferred to the inside of my head, imagining the neurons with dendrites and axons, imagining the streams of electrical impulses, constant movement of chemicals. It never stops. As long as we live, our brain is highly active, whether we sleep or work.
