Dopamine makes us smarter than apes: other forms of “happy hormone” make us human: HEALTH: Tech Times


Look at virtual reality within the pleasure centers of the brain

Humans are smarter than other primates, possibly because they produce more dopamine. Here are other ways in which the brain signaling chemical influences human characteristics and behavior:

High levels of dopamine, the happy hormone, could be behind our brain power and this could explain why humans are smarter than other primates. Humans produce more dopamine than monkeys and chimpanzees.

Why humans are smarter than other primates

In a new study published in the journal Science on November 14, André M.M. Sousa, from Yale University, and colleagues looked at brain tissue samples from humans, chimpanzees and macaque monkeys and discovered that humans abound in the cortical circuits of the neocortex and striatum that help facilitate dopamine production.

The researchers also found that the TH gene, which leads to dopamine production, was expressed in the human neocortex and striatum, but absent in other primates.

Sousa said that the size of the human brain can explain to us that we have more brain power than other primates but size alone does not distinguish our brain from those of chimpanzees and monkeys.

"Our integrated badysis of the data generated revealed several molecular and cellular features of the phylogenetic rearrangement of the human brain across multiple levels, with relevance to brain function and disease," the researchers wrote in their study.


Dopamine is a neurotransmitter that is crucial for the greatest function. The chemical signaling brain plays a role in our movement. It is also badociated with many cognitive skills in which humans stand out, such as concentration, learning, the pursuit of pleasure and planning.

Dopamine has long been badociated with the reward system and is also blamed for impulsive behavior and addiction. Previous studies have shown how dopamine influences human characteristics and behavior.

In a 2016 study, researchers discovered that facial recognition, a social and survival mechanism that helps humans identify and initiate interaction with other individuals. or not, it is linked to the natural reward system that is reinforced by dopamine.

Dopamine also seems to have something to do with the bad and potentially deadly habit of texting while driving. The brain releases dopamine when a driver receives a text message on the phone and more dopamine is released when the message is positive. The researchers said the appeal of texting while driving is similar to that of gambling.

Another study also found that the chemical may help explain why people still choke on fattening foods and drinks despite the need to lose weight. The researchers found that increased levels of dopamine make people more likely to choose instant gratification than to expect a more beneficial reward later.
