For further information see also: Neurobiology of emotions: what happens in the brain when a person experiences an emotion Ancient Brain (reptilian) The Ancient Brain works in a totally automatic way, it is ancestral, that is, the first part of the brain that developed in the evolution of the human species and is therefore . It also has specific characteristics that can be summarized as: a) it deals with basic vital functions (heartbeat, breathing, digestion but also more trivially the blinking of the eyelids and all other movements) b) it also deals with deciding, in a fraction of a second, and evaluating situations of Safety / Danger (it worries about our survival) c) it acts on sexual drives and on the reproductive stimulus (reason why sexual calls continue to have a strong attractive power in every culture and era, at least in terms of stolen attention) d) determines the hunger stimulus , intervenes on the desire to feed oneself, to eat (also a basic drive for survival).human brain evolution Can Neuromarketing Help Us Understand How australia telegram data Our Decisions Are Made? If we keep in mind that at any given moment our senses receive more than 11 million pieces of information per second , but we consciously process only 40 of them , we immediately realize the complexity of every action and decision-making process. The eyes alone send more than 10 million to the brain. We therefore take in 11 million pieces of information per second but we consciously process only 40 of them. What happens to the other 10,999,960? Hence the other interesting hypothesis (confirmed by research in the field of neuroscience) that this information is deposited in some part of our brain where it combines to produce new and original ideas when needed, unbeknownst to our conscious mental state which only in hindsight recognizes their validity.
