|Neonate – babies from birth to 1 month.|
-Connections in the brain
- Head measurement increased 35% in the first year
- Brain development: changes in the brain’s communication system.
Basic Brain Structures
Neurons – Long thin nerve cells that make up nervous system
o Created before birth
o 70% in cortex (brains outer layer)
Axons - Nerve fibers that extend from neurons that spend impulses
Dendrites – Nerve fibers extending from neurons that receive impulses
at birth more than 100 million neurons are present.
Phenomenal growth is referred to as transit exuberance- fivefold increase in dendrites in first years
As many as 15,000 connections may be made per neuron.
Experience enhances the brain
Specifics of brain structure and growth depend party on experience.
o Exuberance is transient – transitional stage between newborn brain’s immaturity and the maturity of older child’s or adult’s brain
o Under use neurons and inactivated, or pruned
Reactions of stress
o Experiencing stress may cause overproduction of stress hormones
o Developing brain can lose capacity to react normally to stress
o Normal neuron connections may have been pruned for rapid response to repeated stress.
-William Greenough identified 2 experience-related parts of brain growth
Experience – expectant brain fuctions – require basic common experience to develop normally
Experience- dependent brain functions
Depend on particular and variable experiences to develop
Human brains are designed for expected experiences
o How the brain is structured and connected will depend on those experiences.
o The brain expects certain experiences at certain ages
§ These experiences critical if connections are to form: if connections not formed, plasticity may allow new connections and pathways as experiences continue.
Sensation and Perception
All senses function at birth
-Sensation – the response of sensory system when it detects stimulus
o Begins with outer organs – nose, eyes, etc.
Perfection – Mental procession of sensory information when brain interprets sensation
o Begins in the brain and requires experience
Cognition – thinking about what was perceived.
begins prenatally and is acute at birth
certain sounds trigger newborns’ reflexes
newborns particularly attentive to human voice
newborns’ sensitive hearing combines with brain to distinguish sounds
vision the least mature sense at birth
visual experience combined with visual cortex maturation improves vision
o with time scanning becomes more organized, efficient, and centered.
binocular vision – ability to focus two eyes in a coordinated manner to see single image
Tasting, smelling and touching
Taste – functions at birth; calmed by sugar, sensitive to sour
Touch – comforted by human touch; feel pain
Smell – can distinguish between odors and have preferences
Early sensation is organized for
o Social interaction
Most visible and dramatic body change of infancy.
Reflexes for survival are categorized
o Maintain oxygen supply (breathing)
o Maintain body temperature (crying, kicking)
o Manage feeding (rooting and sucking)
o Swallowing aids feeding
o Spitting up if too much has been swallowed
o Crying when stomach empty
Gross motor skills
involve large muscle and body movements
o crawling, creeping, walking
o Cephalo caudal trend - top down increase of attributes
o Proximal distal – center out increase of attributes
