Prenatally, how many nerve cells were formed in your brain per minute?

The total estimated number of nerve cells or neurons in a fully developed brain is approximately 1 trillion. During the prenatal life or the period prior birth, the brain produces roughly 2.5 million neurons per minute. This makes the most critical and vital stage of human brain development since almost all of the nerve cells were generated under this period.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
