Advanced NCS Flashcards
Approximately, how many brain cells does a baby have at birth and how much of an increase is there in the first month of life?
~ 1 billion and it increases 20 fold in the first month of life.
How many lines of communication (synapsis) are there at 4 weeks of age?
Over 1 trillion
What does promoting optimal brain development look and not look like?
It is having loving care by a consistent caregiver, having proper sleep and nutrition, as well as, proper interaction and engagement at appropriate times.
It is not things such as beginning to teach your infant a foreign language or having them watch educational videos.
What is so great about promoting optimal brain development?
Promoting optimal brain development sets baby up to have their best possible life. Strong connections are made in the brain early on that help baby to develop healthy coping strategies, communication skills, feelings of attachment and security, and more.
Why do we want mimic the womb, especially during the first three months?
Mimicking the wombs helps baby feel safe and secure which promotes optimal brain development.
How do we mimic the womb?
- swaddling
- white noise
- movement (swaying, rocking, bouncing, etc)
- a dark room.
How do we promote optimal brain development?
- mimicking the womb
- providing the best possible nutrition
- Maintaining body temp (esp. in preemies)
- providing consistent comfort
- movement
- ensuring baby feels safe and secure (responds to cries for example)
As caregivers, how can we help promote optimal brain development? The 5 “S’s”
- swaddle
- sway
- shush
- side hold
- suck
What are the 5 truths we know about infant brain development?
- Intelligence is both genetic and able to be influenced.
- Most major organs are fully developed in miniature at birth except the brain.
- Our brains are born unfinished for a reason.
- Early development matters.
- The overall pattern matters more than each small decision.
Is intelligence fixed at birth?
No, but for a long time it was believed to be. Intelligence is both genetic and able to be influenced. It is not fixed at birth. Environmental factors affect a child’s intelligence and future generations as these experiences alter an infant’s genes which they can pass onto their children.
Can a pregnant person’s stress affect baby’s development?
Yes, if a pregnant person experiences prolonged stress or a traumatic event it can alter the baby’s gene development and activate negative traits (example, aggression) that they are predisposed to. Once these traits have been genetically activated they will be passed down to the next generation.
How does an infants early experiences affect their genes?
Consistent early experiences turn on or protect against genetic traits that baby is predisposed to. Good bonding, especially early on, has a great impact on whether an infant will develop negative behaviors such as aggression, hyperactivity, and compulsivity.
What one part of the body is the same size at birth and death?
The cornea
How big is the brain at birth?
1/4 it’s full adult size.
When do brain cells (neurons) develop?
An infant’s neurons are formed before birth but they do not develop completely until after birth.
What are synapses and when do they develop? What determines their development?
Synapses are connections between neurons and they are formed mostly after birth. They form in response to their environment.
What are axons?
Axons are neurons that send information.
What are dendrites?
Dendrites are neurons that bring in information.
What type of neuron does a child primarily develop in the first three years of life?
Dendrites.
Why are our brains not fully developed at birth?
- We cannot be pre-wired to meet every life scenario.
- We grow connections (synapses) as needed.
What happens when we stop using or needing specific synapses?
Neural pruning occurs - the connections wither away.
What is myelin and what is it’s purpose?
Myelin is a fat layer that develops on synapses that are used frequently. It provides protection for the connection and allows for it to pass faster and be stronger.
How do we create strong synapses? Three “R’s”
- Repetition
- Routine
- Reinforcement
How quickly do synapses form? When do they peak and prune?
Growth is unfathomably rapid in infancy and early childhood. It peaks and are pruned significantly by adolescence.
