5184278045T/F Newborn babies form synapses in their brains at the rate of a hundred new connections each second.False- one million connections per second18
5184284585PlasticityThe ability of an immature brain to change in form and function.19
5184286946PruningThe deterioration and disappearance of synapses that are not used.20
5184294226When does plasticity disappear?Age 4 or 521
5184302845Why is pruning beneficial to the brain?Pruning makes the brain more efficient.22
5184313190Experience- Expectant Brain DevelopmentDevelopment that occurs when we encounter experiences that our brain expects as a normal event. (Ex. Exposure to light)23
5184320360Experience- Dependent Brain DevelopmentDevelopment that occurs in response to specific learning experiences. (Ex. Playing the violin)24
5184338294MyelinationThe process of laying down a fatty sheath of myelin on the neurons. (For the message to be sent successfully)25
5184360788Cerebral PalsyA chronic condition that appears early in development and primarily involves problems with body movement and muscle coordination.26
5184362315Autism Spectrum DisorderA disorder characterized by pervasive impairment in social communication and interaction and by restricted or repetitive behaviors, interests, or activities. Severity is classified by how much support the individual needs to function effectively.27
5184449119How do 70% of cerebral palsy cases occur? The remaining 30%?-Brain injury during prenatal development. -an infection or injury causes damage to the brain28
5184472532Name three parts of a treatment plan for cerebral palsy.Medications- for seizures and muscle spasms Surgery- Lengthen muscles/ tendons that are too short. Physical Therapy- Skill building29
5184492375What part of the brain is enlarged in ASD?The amygdala30

5184555364Cross- Modal Transfer of PerceptionPerception with one sense enables recognition of that object with another sense, such as touch.38
5184576187ReflexesPatterned, involuntary motor responses that are controlled by the lower brain centers.39
5184590418When does prenatal thumb sucking begin?12-14 weeks of gestational age40
5184597630T/F Babies triple their birth weight by the time they are 1 year old.True41
5184599171Gross Motor SkillsSkills that involve the large muscle groups of the body- for example, the legs and arms42
5184599172Fine Motor SkillsSkills that involve small movements, mostly of the hands and fingers, but also of the lips and tongue.43
5184627561Sucking ReflexWhen something touches the roof of the baby's mouth, her lips close, and she will suck reflexively. (2 months)44

5184637938Moro ReflexAlso known as startle reflex. When a baby loses support she will flail her arms and legs outward. When startled, most babies will pull their limbs back in. (3 months)46
5184652362Stepping ReflexIf you support the baby's weight but let his feet touch the ground, he will lift and set his feet in a "walking" motion. (3 months)47
