1. Building a brain

   • The verbal self ?
     • Left side of the brain
       • Communicates the self to others
       • Develops linguistic ability
     • Final stage (2-3 yo)
     • The dorsolateral prefrontal cortex
       • Develops working memory
         • Capacity to hold things in mind & compare them
     • The role of parents
       • Emotional vocabulary
         • Emotional regulation
         • Reflection on emotions
         • Defining sense of self
   • Negative faces ?
     • Triggers stress
       • Cortisol
         • But it's needed to a certain extent
           • "This delivery of norepinephrine helps the orbitofrontal cortex to mature further in toddlerhood, by increasing blood flow to the area and by forming its links (via the hypothalamus) with the parasympathetic nervous system. The parasympathetic nervous system is vital to the growing child, because this is the inhibitory system which enables the child to stop doing something and to learn what behaviour is unacceptable or dangerous".
     • The adult figure ?
       • "What a small child needs is an adult who is emotionally available and tuned in enough to help regulate his states".
       • If unavailable
   • The power of the image ?️
     • The prefrontal cortex
       • Begins maturation at 10 months old
     • Repetition ?
       • Etches experiences onto memory
   • The infant navigator ⛵
     • Social interaction
       • Is key ?
         • "When there is a chronic lack of positive social interaction with others, the capacity to override such primitive responses may not develop".
     • Neuronal pathways
       • Constellations of neurons that become patterns of behaviour & reaction to certain situations & circumstances.
       • Forming patterns of behaviour
         • "Patterns are formed by the ensemble of neurons as they rise into activity, respond to each other and to environmental stimuli, and then fade away, creating a ‘cocktail party’ of chatter in the brain".
   • ? The social brain ?
     • Main areas in the brain
       • The orbitofrontal cortex
         • "acts as a kind of control centre from which these and other parts of the brain can be activated or inhibited".
         • "It holds back what LeDoux calls the ‘fast and dirty’ emotional responses by activating more thoughtful, complex motivations".
       • The prefrontal cortex
         • "It links the sensory areas of the cortex with the emotional and survival-oriented subcortex".
       • The anterior cygulate gyrus
     • How the social brain develops
       • Early stage ?
         • We're social noobs at this point
           • "His social capacities are mostly potential, not actual at birth".
         • Programmable brains
           • "When we are babies, our brains are socially programmed by the older members of our community, so that we adapt to the particular family and social group we must live among".
           • Through experience
         • A pleasurable relationship with your baby ?‍??‍?
           • "The first step in the process is to get the baby hooked on social interaction itself by making it highly pleasurable".
   • The power of a smile ?
     • Eye contact ?
       • Is important
       • Becomes main source of info ℹ️
       • Develops the brain
         • "In particular, between 6 and 12 months, there is a massive burst of these synaptic connections in the prefrontal cortex".
         • Emotionally
         • Socially
   • The basic brain
     • A core brain ?
       • Which ensures survival
     • Social & emotional abilities ?
       • Great for living in groups
       • Complex emotions for social purposes
   • Part 2
