Is There a Blue Spot Inside our Brain?
When you are walking inattentively through a road and suddenly a car honks and you shift your attention immediately to the blowing of the horn.
Have you ever thought about how suddenly our attention shifts? This is due to the presence of the blue spot- a tiny cell hidden deep inside our brain.
The 'locus coeruleus' or the blue spot is the main source of the neurotransmitter noradrenaline which helps us control our attention focus.
While we are inattentive our brains are governed by slow rhythmic fluctuations of neural activity and when our brains are active these oscillations increases
there is a higher production of noradrenaline which refocuses our attention. The study was conducted by the Max Planck Institute of Human Development
and University of Southern California and they came to a conclusion that the blue spot’s noradrenaline regulates our brain’s sensitivity to process
