S(artificial nipple) r (long pause in sucking) o (familiar story) Memory development: infancy to childhood immediately after birth, human infants demonstrate incredible learning abilities: Males > whole brain volumes females > relative hippocampus, caudate nucleus, anterior cingulate gyrus, supramarginal gyrus, and dorsolateral prefrontal cortex volumes. Males > relative amygdala, paracingulate gyrus, and visual cortex volumes neurotransmitters: females > dopamine in some brain regions, serotonin levels in some brain regions, gaba levels in the cortex. Males > serotonin receptors in some brain regions. Monophasic contraceptive = same amount of estrogens in each pill triphasic contraceptive = every few days, the amount of estrogens in the pills changes. Genetic mutations can have measurable effects on learning and memory function. Bdnf - a neurotrophic factor important for long-term potentiation and neuronal health.
