brain development in first year

A

brain has tripled in weight, almost all neurons are present at birth that an individual will have, however neurons increase in size, myelination occurs, synapses increase, connections increase, and areas of cortex take on specialized functions

38
Q

fostered/constrained by experiences
malnutrition- can result in brain damage
stimulation plays a role!

39

18 months

45
Q

brain at adult size by

A

5-8 years old

46
Q

7 years

A

FACE changes! looks more mature, expected to take on more responsibilities because of maturational changes of look

47
Q

physical development

A

result of dynamic interaction among genetics, environment and behavior

  • involves predictable changes in the size (growth) which is driven by genetics, nutrition, health and experiences.
  • changes in FUNCTION (using body to adapt to and explore the environment)
  • environmental experience of the organism is directly affected by biological endowment, that is, the expression of the genes and the architecture and function of the central nervous system.
48
Q

Growth vs. Maturity

A
  • growth: increase in size, weight, power (gradual developmental towards maturity)
  • growth and maturity not the same thing!
49
Q

Growth in first year

A
  • growth in first year is SINGLE best indicator of well being
  • growth in first year more rapid than at any other time except prenatally
50
Q

newborn head

A

1/4 of body!

51
Q

head circumference

A
  • measuring head circumference helps us to see if brain is growing appropriately
  • head circumference increases by 12 cm by end of first year
  • head circumference increases 5 cm by end of second year
  • between 3-20 years: only increases 5-6 cm
    (why we stop measuring after 3 yrs old)
52
Q

stability in children

A
  • problem for young children due to their higher center of gravity and small base of support
  • disproportionate growth in head, trunk and legs causes changes in the center of gravity
53
Q

nutrition and feeding recommendations

A
  • human milk is superior
  • commerical formula can adequately support growth
  • delay introduction of 100% juice until at least 6 months
  • limit juice to no more than 4-6 ounces a day
  • start other sources of nutrition by 4-6 months (rice cereal, pureed baby foods)
54
Q

failure to thrive

A

decreased rate of daily weight gain for age
depressed weight for height always reflects inadequate nutritional intake
- biological/medical basis
- access to food
- parenting
-emotional state
- sensory intolerance

55
Q

epigenetics

A
  • structural genome is the hardware of the genes themselves
  • operating system which turns genes on or off using chemical modifiers
  • does not change the DNA sequence
  • just how gene is expressed is changed
  • environmental influences!
56
Q

pregnancy and teratogens

A
  • substances that cause birth defects during pregnancy

- Thalidomide (used for morning sickness in 50s): led to defects of limbs!

57
Q

brain in utero

A

smooth until around 8 months (more folds, grooves), more complex by birth!

58

A
  • brain and spinal cord
60

  • mature at birth
  • involved in vital bodily functions
  • sleep and arousal
  • many reflexes
  • basic sensations
62

  • emotion, motivation, regulation, memory
63
Q

lower limbic system

generate emotions , facial expressions, and physiological changes, mature at birth

64
Q

higher limbic system

A
  • underlie the conscious experience of emotion
  • regulate emotion
  • develop over childhood and adolescence
65
Q

amygdala

A

threat!

  • monitors senses and thoughts
  • alerts other parts of brain when something significant happens
  • basic emotions such as fear and anger
  • recognizes emotions in others
66
Q

hypothalamus

A

physiological regulation

- governs the stress response

67
Q

hippocampus

A

memory

  • involved in long term storage of memories
  • close connection between amygdala and hippocampus links emotion and memory
  • first memories around 3-5 years old (due to language development too)
68
Q

Cortex

A
  • thinking part of brain
  • sensory, motor and association areas
  • takes longest to develop
  • where we make conscious decisions
69
Q

left hemisphere

A

process information analytically

70
Q

right hemisphere

A

process information holistically

71
Q

cerebellum

A
  • coordinates and fine tunes movement
  • critical for posture, balance and coordination
  • plays role in emotion and cognition
72
Q

stress and the brain

A
  • toxic stress can lead to impaired cognition
  • stress is an actual or perceived threat in the context of uncertainty about our capacity to manage the threat
  • occurs when demands exceed available resources
  • physiological event: overwhelms system
  • HPA (stress response system)
  • types of stress: positive, tolerable, toxic
  • secure relationships buffer against stress!!
  • we can provide control, predictability and nurturance to minimize stress
73
Q

sensory processing

A
  • sensory integration is the organization of sensation from the body and environment for an adaptive response
  • sensory input (sensory receptors stimulated), then processing (sensory information organized and interpreted, response is generated
  • sensory processing affects our ability to regulate arousal, attention, interact with people and explore move and learn
74
Q

self-regulation

A
  • ability to control the nature and intensity of one’s response to stimuli
  • ability to organize sensation in order to calm, tolerate change, attend/focus
75
Q

vestibular

A
  • gravity and motion of head in space
  • balance and equilibrium
  • inner ear
    contributes to: balance, regulation of muscle tone, coordination, ocular-motor control, arousal and attention, emotional states
76
Q

proprioceptive

A
  • muscles and joints
  • position of body in space
  • position of body parts in relation to one another
  • allows us to: orient our body in space, time movements, plan organize and remember movements, modify force exerted by muscles, develop a body schema
77
Q

Sensory Processing Thresholds

A
  • zone of proximal arousal needed!
    low threshold: over-reactive (takes little input to activate, hyper active ): sensory avoid ant
    high threshold: under-reactive (takes a lot of input to activate, hypo reactive): sensory seeking
78
Q

hearing

A

by 23 weeks!

  • at birth: ear is structurally mature
  • fluid in inner ear limits sound wave travel for a few days
  • by 6 months: full range of hearing
