a fully grown brain still waiting on its frontal lobe to log in

means A young person in the transitional stage between childhood and adulthood, roughly the teenage years, marked by physical, emotional, and social development.

from From Latin adolescere, 'to grow up, mature' — built from ad- ('toward') plus alescere ('to be nourished, to grow'). Its present participle adolescens gave us 'adolescent,' while the same verb's past participle, adultus, grew up into 'adult.' So linguistically the adolescent and the adult are the same plant caught at two different moments of growing.
