PSYC23H3 Lecture Notes - Lecture 6: Memory Consolidation, Synapse, Ring Signature
Document Summary
End of last lecture on stress in preterm infants. Contingency learning at 3 months at day 1. Contingency learning at 3 months after 24 hours. Delayed imitation (i. e. memory) after 15 min and after 24 hours. ** the questions are all in the ppt. All during a period of rapid brain growth: preterm populations. Greater variation and impairment in cognition in preterm vs. full-term populations. Slower information processing (e. g. habituation, contingency detection, deferred imitation) Mothers at risk of premature delivery receive steroids. Cortisol at 3, 6, 8, and 18 months. Cortisol levels are lower in preterm infants than in full-term infants at 3 months. Normal developmental decline in cortisol levels from 3 to 18 months is altered in extremely premature infants: summary of early stress. Exposure to prenatal steroids and early stress have independent effects on dampening hpa activity in extremely premature infants in the neonatal period.
