The Life Cycle of Memory – p. 12-13
- “Spark of Life” – fetus – brain voltage – 4-5 times that of an adult; but speed is slower – can’t retain all.
- “Infantile Amnesia” – birth to four years old – “Infants and toddlers can’t organize their thoughts or recall information.” p. 12
- “Memory Retention” – ages 5-12 and 13-20 – blasts off during adolescence
- “Consolidation of Adulthood” – ages 20-40 “The brain organizes itself to function more effectively, and we are at our peak performance. This is the time when people tend to establish their careers, start families, and generally settle down.”
- Slow, but steady decline – Women beginning as early as age 40; Men usually have another 10 years before this decline begins.
“Each decade thereafter, mild cognitive impairment (MCI) begins as brain speed and voltage are lost.” p. 13
