Brain Frontal Lobes Not Sole Center of Human Intelligence, Comparative Research Suggests
Summary: Recent research shows that the frontal lobe is not the only source of intelligence, and that other areas of the brain are just as important. Originally, larger frontal lobes were associated with higher intelligence in different species and that the larger lobes were what made humans different. This was also proved false as the size of an animal brain's frontal lobe is proportional to the size of that of humans. This information was suspected by scientists previously, but was further validated in this experiment conducted by Durham and Reading universities. The cerebellum has been suggested to have a larger role in intelligence and the evolution and development of the brain. Also it has been suggested that damage to the cerebellum can cause diseases such as autism and dyslexia.Relevance: In the Humans 1 unit of our curriculum, we studied the nervous system. The brain is part of the central nervous system, and processes information. We also studied the different lobes of the brain, one being the frontal lobe, which is discussed in this article. We learned that the cerebrum is the site of processing information, and this article discusses superior cognitive abilities in humans, to which the cerebrum is an important contributor.

How did the experiment prove that larger frontal lobes did not mean higher intelligence?
ReplyDeleteOne thing that the researchers showed through their experiments was that the human brain was the exactly the same proportion to body size as brains of other species. I am not completely sure what the exact experiment was.
DeleteWhat other parts of the brain do scientists suspect are involved with intelligence, if any?
ReplyDeleteAs I said, the cerebellum, which was originally considered more primitive, is thought to have more importance in intelligence. The researchers only said that parts considered more primitive were actually important, but did not state specifics other than the cerebellum.
