With regard to Mind advancement, this time frame corresponds towards the 3rd trimester of gestation in the human. The medical importance of such findings is just not clear; even so, studies in juvenile animals recommend neuroapoptosis correlates with very long-term cognitive deficits (see “Warnings-Pediatric Neurotoxicity”, “Precautions Pediatric Use”, and “Animal Pharmacology and/or Toxicology”).
