Because the brain is pretty much magic. Scientists don't have any idea how it works and it has nothing to do with size, otherwise tall/big people would be the smartest and short/small people would be the dumbest. The only thing scientists know about the brain is what it is physically made of and how you can screw it up by doing certain things to it.
There are several ways to measure the human brain: weight (about 3 pounds), volume, intelligence.
Logical indicator and Predictive Indicator
Every part of the brain - except possibly the brain stem, where involuntary processes are - contributes to intelligence.
The brain is in fact alone
cerebrum is the centere of intelligence.
laying out of its intelligence.
The brain symbolizes intelligence, creative thinking, and knowledge. It is often associated with mental abilities, problem-solving, and intelligence.
cerebrum is the centere of intelligence.
The brain is the organ which thinks. Without it we would have no intelligence.
Mammalian intelligence depends mostly on the folds present in the cortex. The more folded the cortex the smarter. If you compare a rat brain to a human brain, the rats brain will be alot smoother and flatter.
Learning, intelligence, and judgment occur in different regions of the brain. Learning involves multiple areas including the hippocampus and prefrontal cortex, while intelligence is associated with overall brain function and connectivity. Judgment is linked to the frontal lobe, specifically the prefrontal cortex, which plays a crucial role in decision-making and moral reasoning.
