  • Dr Megan GunnarSocial Relationships control cortisol levels in infants and young children.Children with secure attachments to their caregivers show stable cortisol levels.The key ingredient to buffering stress is sensitive, responsive, individualized care.Its not separation from parents, but the experience in child care that triggers their stress responses.

  • Research on Quality Treating children with respectDeveloping relationships with familiesEnsuring programmes focus on children feeling safeHutchins and SIMS 2000

  • Research on QualityMeeting the individual needs of childrenEnsuring staff remain in their positions long enough to be able to develop and maintain relationships with children

    All of these dimensions of quality are fundamental to developing and maintaining strong relationships between caregivers and children (Hutchins & Sims, 2000).

    .

    In brain development there are complex pathways between the sensing system and how the brain works. These pathways are dependent upon how well the individual neurons interact with each other through their synaptic junctions. Thus, when you see a snake the optic nerve pathway intersects with the visual thalamus in the centre of the brain which can then signal the amygdala to generate what is often called a fear response. The optic nerve pathway continues on to the visual cortex which can help interpret whether the snake is real or is a stick. With normal brain pathways and function, the signal from the visual cortex can if the signal is a stick shut down the fear response through the amygdala. If the brain develops in an inappropriate manner, there are some things which an individual can sense in a fear response that it is not possible to turn around when other cognitive functions signal that this should not be a fear response. This slide summarizes what we know today about experience-based brain development and the brains plasticity. The development of the sensing neurons occurs during an early sensitive period of brain development. The neurological pathways for stress also have a sensitive period of development in early life. The hippocampus, which plays an important part in memory, has a plasticity that extends throughout life.The expression of genes for neurological development is in different parts of the brain strongly influenced by the stimuli they receive in early life.
