MEMORY & THE BRAIN

The grown-up human mind weighs overall around 1.5 kg (3lbs), and is about the measure of a little head of cauliflower. It is delicate (having a consistency like delicate gelatine or firm tofu) and, notwithstanding being alluded to as "dark matter", the live mind is really pinkish-beige in shading (in spite of the fact that it might turn dim after death) and somewhat grayish in the inside. The inside white matter gives a large portion of the mind's structure and interchanges, while the dark matter that encompasses the white matter gives the majority of the real calculation and intuition capacities (despite the fact that this is, obviously, an improvement). 

Right around 80% of the cerebrum comprises of water (mostly in the cytoplasm of its cells), with a further 10-12% being greasy lipids and 8% protein. Despite the fact that it represents only 2% of body weight, it utilizes completely 20-25% of the body's oxygen supply, supplements, and glucose (as fuel), all of which are provided by consistent blood stream. It is secured by the thick bones of the skull, suspended in cerebrospinal liquid, and confined from the circulatory system by the blood-mind hindrance, however the sensitive way of the human cerebrum in any case makes it powerless to many sorts of harm and infection. 

It is a massively complex organ, with an expected 100 billion neurons passing signs to each other through upwards of 1,000 trillion synaptic associations. It constantly gets and breaks down tactile data, reacting by controlling every substantial activity and capacities. It is additionally the focal point of higher-request considering, learning and memory, and gives us the ability to think, arrange, talk, envision, dream, reason and experience feelings.
