PSYC 363 Lecture Notes - Lecture 3: Prefrontal Cortex, Auditory Cortex, Frontal Lobe
Document Summary
Growth: average 7. 5 pounds and 20 inches long: eats about every 2 to 4 hours, by 24 months the baby should be 28 pounds,4x heavier than at birth. Prenatal and postnatal brain growth is crucial for later cognition: head sparing: a biological mechanism that protects the brain of the infant when malnutrition disrupts body growth. Developing cortex: frontal cortex (assists in movement) prefrontal cortex helps planning and self-control. Auditory cortex for hearing which is acute at birth. Visual cortex vision is least mature since it had nothing to see in the womb: prefrontal cortex is the last to develop (continues to develop through teen years even. ) Transient exuberance: early dendrite growth, very rapid. Dendrite growth (branches in nerve cells) make neural connections within the brain, allows brain growth. Pruning: if connections between dendrite aren"t used, they"ll die, making room for new connections. Harm and protection: all infants need stimulation, need protection, half self-righting which remedies self-deficits.
