1.3.1 Early Brain Development

Cards (35)

  • Synaptogenesis involves the rapid formation of synaptic connections
  • Critical periods are sensitive windows where the brain is particularly responsive to environmental stimuli
  • Synaptogenesis peaks around the age of 2 years old.
  • Synaptogenesis creates a dense neural network while pruning refines and streamlines pathways.
  • Myelination involves the formation of a myelin sheath around the axons of neurons.
  • Critical periods are specific windows of time when the brain is highly responsive to environmental stimuli
  • Disruptions during critical periods may have severe and lasting impacts on cognitive development.

    True
  • The stages of brain development during early childhood include synaptogenesis, myelination, and pruning
  • Pruning involves the selective elimination of unused synapses.

    True
  • Synaptogenesis peaks early in childhood and creates new synaptic connections
  • Myelination increases the speed and efficiency of signal transmission along neurons.

    True
  • Frequent engagement with caregivers fosters cognitive growth in early childhood.

    True
  • Pruning is the process of eliminating unused synapses.
    True
  • Match the function, timing, and purpose of synaptogenesis and pruning.
    Synaptogenesis ↔️ Formation of new connections
    Pruning ↔️ Elimination of unused connections
    Timing of Synaptogenesis ↔️ Peaks early in childhood
    Purpose of Pruning ↔️ Streamlining neural pathways
  • Disruptions during critical periods can have severe and lasting impacts on cognitive development.
    True
  • What is the primary function of pruning in brain development?
    Elimination of unused connections
  • Match the critical and sensitive periods with their definitions, impacts, and examples.
    Critical Periods ↔️ Specific windows for high responsiveness
    Sensitive Periods ↔️ Broader windows for responsiveness
    Example of Critical Period ↔️ Language acquisition
    Example of Sensitive Period ↔️ Social and emotional development
  • Critical periods are specific windows of time when the brain is highly responsive to environmental stimuli and experiences
  • Understanding critical periods is crucial for providing the right environmental conditions for healthy brain maturation.

    True
  • Myelination improves signal transmission
  • Synaptogenesis creates a dense neural network, while pruning refines and streamlines these pathways.

    True
  • Myelination forms a myelin sheath around neuron axons
  • Genes provide the blueprint for brain structures and function
  • What does myelination improve in brain development?
    Signal transmission
  • Order the stages of brain development during early childhood.
    1️⃣ Synaptogenesis
    2️⃣ Myelination

  • Myelination increases the speed and efficiency of signal transmission in neurons.

    True
  • What type of disruptions during critical periods can have severe and lasting impacts on cognitive development?
    Environmental disruptions
  • An example of a critical period is language acquisition
  • Place the stages of brain development during early childhood in the correct order:
    1️⃣ Synaptogenesis
    2️⃣ Myelination
    3️⃣ Pruning
  • Critical periods are sensitive windows where the brain is particularly responsive to environmental stimuli and experiences
  • Pruning occurs throughout childhood and adolescence.

    True
  • Critical periods are specific windows of time when the brain is highly responsive to environmental stimuli and experiences
  • Exposure to toxins like lead can disrupt brain development
