Neurology

Cognitive development

• WHAT connections in WHAT

• WHAT connection in WHAT

Cognitive development

• PHYSICAL connections in BRAIN

• MENTAL connection in IDEAS

What are the three types of neurons

• WHAT

• WHAT

• WHAT

What are the three types of neurons

• Sensory neurons

• Motor neurons

• Interneuron

Neurogenesis

• We are born with most of our WHAT

Neurogenesis

• We are born with most of our NEURONS

Neurogenesis - Neurons first develop

• Low in WHAT

• Then spread WHAT

Neurogenesis - Neurons first develop

• Low in BRAIN STEM

• Then spread UPWARDS

Neurogenesis

• WHAT starts low

Neurogenesis

• MYELINATION starts low

Synapse

Connection between neurons

Synaptic pruning

Cutting the connection between neurons

Synaptogenesis peaks for different WHAT at different WHAT

Synaptogenesis peaks for different REGIONS at different TIMES

Synaptogenesis WHAT over time

Synaptogenesis FLUCTUATES over time

Synaptogenesis changes in cortical WHAT and WHAT

Synaptogenesis changes in cortical THICKNESS and INTELLIGENCE

What are the three types of brain specialization

• WHAT

• WHAT

• WHAT

What are the three types of brain specialization

• Experience-expectant process

• Experience-dependent process

• Brain plasticity

Experience-expectant process

• WHAT

• WHAT hard-wired

• Helps prepare for common WHAT

Experience-expectant process

• NATURE

• GENETICALLY hard-wired

• Helps prepare for common ENVIRONMENTS

Experience-Dependent process

• WHAT

• Experience WHAT and WHAT brain

• Music, colour, bilingualism

Experience-Dependent process

• NURTURE

• Experience REINFORCES and STIMULATES brain

• Music, colour, bilingualism

You have basic WHAT at birth and gets more detailed over time

You have basic PERCEPTION at birth and gets more detailed over time

Can’t WHAT until the brain can WHAT

Can’t PERCEIVE until the brain can DETECT

Neurons are not WHAT

Neurons are not ORGANIZED

Sensory development

• WHAT studies

Sensory development

• HABITUATION studies

Chemical senses

• WHAT

• WHAT

Chemical senses

• Smell

• Taste

Chemical senses

• WHAT to develop

• WHAT at birth

• Recognize familiar WHAT

• Hypersensitive WHAT

• Preferences

Chemical senses

• EARLIEST to develop

• KEEN at birth

• Recognize familiar SMELLS

• Hypersensitive TONGUE

• Preferences

Hearing

• Develops at WHAT months WHAT

• Not as well developed at birth

• Only some WHAT

• Rhymes and melodies

• WHAT

Hearing

• Develops at 7-8 months GESTATION

• Not as well developed at birth

• Only some PITCHES

• Rhymes and melodies

• LOCALIZATION

Sight

• Most WHAT at birth

• Responsive to WHAT

Sight

• Most UNDERDEVELOPED at birth

• Responsive to LIGHT

What are the four things to sight

• WHAT

• WHAT

• WHAT

• WHAT

What are the four things to sight

• Resolution

• Colours

• Facial perception

• Depth perception

Resolution

• Details

• Patterns

Colours

• Less sensitive to colour differences

• Primary colours

Facial perception

Contrasts important

Depth perception

• Infants have some sense of depth

• Develops with COORDINATION

• Visual cliff
