Brain: Left vs. Right!
It is a fact that some people really have a problem with telling rapidly which is right and which is left (researches proved that women more than men), but your brain doesn’t. Your left brain and right brain are quite different. The right brain hemisphere is linked mostly to emotional functions and music feeling, while the left hemisphere is more analytical, linked to logical thinking, speech and abilities.
The research was conducted by a team led by Stephen Wilson at the University College London, and published in the journal “Neural Development,” shows for the first time how the left and right parts of our brain are wired at neuronal level. Basically, the team focused on the left- and right-sided neurons (brain cells) in the brain nucleus called the habenula in zebrafish, in this case similar to that of the human brain. The team made the habenular neurons to synthesize a bright green fluorescent protein which enabled the researchers to visualize their axons, the long nerve fibers that transmit information between neurons.
The team found two types of habenular neurons, both encountered in the left and the right side. But the left neurons predominantly had spiral axons shaped into a domed crown. These neurons were scarce on the right. Most of the right neurons made flat, shallow spirals, very rare in the left side of the habenula.
The left and right habenular neurons connect to the same brain area, where their signals either combine or are processed independently.
