The visual areas of the brain are in the very back
These brain facts might sound counterintuitive, considering your eyes are in the very front of your head, but the part of your brain responsible for vision, the occipital lobe, is located in the very back. “Bang someone on the back of the head and they will see stars, not sounds,” says Henry Soper, MD, clinical psychology faculty member in the School of Psychology at Fielding Graduate University. Similarly, the left side of your brain controls the vision on your right side and vice versa. The same goes for how our brain processes sound – on opposite sides of the head. “Although evolutionary theories have been proposed, the bottom line is we really do not know why,” Dr. Soper says.
Brain scans can “light up” when a person is in love
Some may think that being “in love” is only an idea or merely a term people use, but brain scans reveal otherwise. “For people who are romantically in love, functional MRI brain scans can show activity where dopamine, the ‘feel-good’ neurotransmitter, is present,” says Dr. McQuiston. “Other areas in the brain associated with pleasure and reward can also show greater activity for people who have fallen in love.”
Your brain activity is as unique as your fingerprints
Research published in the journal Nature Neuroscience suggests that a person’s brain activity may be as unique as his or her own fingerprints. To reach their conclusion, scientists used functional magnetic resonance imaging (fMRI) to create “connectivity profiles”, which allowed researchers to identify the brain activity of more than 100 individuals. “Learning about individual brain connections offered scientists specific insights about an individual’s intelligence or personality,” explains Dr. McQuiston. “This could have implications for how scanning brains might be used in the future to one day help individualise care for each unique person.”
