Unique Human Brain Structures Probably the Result of Evolution: Report
Researchers from the University of Leuven have presented a report that suggests that human brain has a unique cortical network. The findings are published in the Journal of Neuroscience.
In this significant study, the scientists conducted functional brain scans in rhesus monkeys and humans under two different circumstances- first when they were taking rest and second when they were watching movie. Then they compared the functions and locations of cortical brain networks during these different activities. The findings claim that even when resting, human brain remains very active and these active brain areas form resting state networks.
The researchers took the help of Functional Magnetic Resonance Imaging to represent the involvement of particular parts of brain in a certain activity.
"For the most part, these resting state networks in humans and monkeys are surprisingly similar, but we found two networks unique in humans and one unique network in the monkey", said Professor Wim Vanduffel, from the University of Leuven.
In addition, he said that the unique brain structures found in humans are not present in the brain of monkey. These unique human brain areas are located at the front and back of the cortex and perhaps are associated with the unique cognitive capabilities of humans.
Scientists have suggested in the report that these unique human brain networks may have formed during evolution.
