What are the first two steps in the sequence of brain and CNS development?
What are the first two steps in the sequence of brain and CNS development?
The first two steps are cell proliferation, which generates immature neurons, and migration, where neurons move to different sites in the brain.

Study Notes
Motor Development
- Study of changes in growth, development, and motor performance across the lifespan
- Focus on similarities between infants and older adults
Factors Influencing Motor Performance
- Heredity (genetic predisposition)
- Maturation (biological growth and development)
- Experience (practice and learning)
- Growth (physical changes)
Brain and CNS Development
- Cell proliferation: Generation of immature neurons
- Migration: Movement of neurons to specific locations in the brain
- Integration: Formation of connections between neural groups
- Differentiation: Progression of neural control
- Myelination: Covering of neural pathways with myelin, improving signal transmission
- Cell necrosis: Death of cells
Growth and Control Sequences
- Cephalo-caudal: Growth proceeds from head to toe
- Proximal-distal: Growth proceeds from the center of the body outwards
Skill Types
- Phylogenetic: Species-specific, naturally acquired. Example: Crawling
- Ontogenetic: Learned, individual-specific. Example: Dancing
Reflexes
- Involuntary response to a stimulus
- Suppressed during development
- Diagnostic tool for neurodevelopment
- Essential for survival
Reflex Categories
- Primitive (basic reflexes)
- Postural (related to body position and balance)
- Locomotor (related to movement)
Spontaneous Movements
- Involuntary movements that occur without external stimuli
- Help to develop motor control
Creeping vs. Crawling
- Crawling: Body drag
- Creeping: All fours
- Creeping develops before crawling
Prehension Development (Manual Control)
- Palmer grasp: Using the whole hand to grasp objects
- Pseudo opposition: Using thumb and fingers in a crude opposition
- Thumb opposition: Fine motor control with thumb and fingers
- Mastery: Skilled and coordinated use of the hand
Locomotion Development
- Crawling
- Creeping
- Walking
- Running
- Leaping
- Jumping
- Hopping
- Galloping
- Sliding
Peak Performance
- Skills requiring fast reflexes: Peak performance usually around 20s
- Skills requiring strength: Peak performance usually around 40s
Decline in Physical Functioning
- Average adult loses significant physical function between ages 30-70
Motor Development
- Study of changes in growth, development, and motor performance throughout life
- Includes similarities between babies and older adults
Factors Influencing Motor Performance
- Heredity
- Maturation
- Development
- Experience
- Growth
Brain and CNS Development
- Cell Proliferation: Generating immature neurons
- Migration: Movement of neurons to different locations in the brain
- Integration: Interaction of neural groups
- Differentiation: Progression of control within the brain
- Myelination: Coating of neural pathways to improve transmission speed
- Cell Necrosis: Death of cells
Growth and Control Sequences
- Cephalo-caudal: Growth progresses from head to toe
- Proximal-distal: Growth progresses from the midline of the body to the periphery
Phylogenetic Skills
- Naturally acquired skills specific to the human species
- Example: crawling
Ontogenetic Skills
- Learned skills that depend on individual experience
- Example: dancing
Reflexes
- Involuntary responses to stimuli
- Suppressed in infancy
- Important for diagnosis and survival
Reflex Categories
- Primitive reflexes
- Postural reflexes
- Locomotor reflexes
Spontaneous Movements
- Unintentional movements that appear in infancy
Creeping vs. Crawling
- Crawling involves dragging the body, while creeping involves all fours
- Creeping precedes crawling
Stages of Prehension (Manual Control)
- Palmer grasp: Using the whole hand to grasp an object
- Pseudo opposition: Using the thumb and fingers to grasp an object, but not fully opposing
- Thumb opposition: Using the thumb and fingers in a fully opposing manner to grasp an object
- Mastery: Skilled manipulation and control of objects
Locomotion Development Sequence
- Crawling
- Creeping
- Walking
- Running
- Leaping
- Jumping
- Hopping
- Galloping
- Sliding
Peak Performance Age
- Skills requiring fast reflexes: Peak performance in the 20s
- Skills requiring strength: Peak performance in the 40s
Adult Physical Functioning Decline
- Average adults lose a portion of their physical functioning between the ages of 30 and 70
