  • STEP 1 Proliferation: The multiplication and division of an unborn baby's cells that will become neuron's
  • STEP 2 Migration: When neuron's move outward to there destined location. This positioning allows for neural circuits.
  • STEP 3 Circuit formation: When the axons of new neuron's grow out to target cells and form synapses with them. This process allows for neuron's to communicate with each other
  • STEP 4 Synaptic pruning: The elimination of excess neuron's that have not established a connection with neighbouring cells. Pruning occurs during infancy and childhood. Pruning increases the efficiency of the nervous system.
  • STEP 5 Myelination: When the axon on a child's neuron become insulated by a substance called Myelin. Myelin increases the transmission of signals within a neuron.
  • What is brain plasticity: The ability of the brains neural connection and synapses to change through growth and reorganisation. It refers to the way the brain changes to intrinsic or extrinsic stimuli.
  • Adaptive plasticity: The brains ability to grow and re organise neural connections in response to sensory output from the environment.
  • adaptive plasticity: The ability of neural connections to reorganise in response to learning or compensating for lost functions.
  • Stress is associated with the reduced volume of the hippocampus.
  • Prolonged stress can later lead to anxiety disorders and depression. These Illnesses stem from the amygdala, Hippocampus and thalamus within the brain
  • Prolonged stress can cause dendrite shrinkage within the hippocampus
  • This decrease in dendrite density within the brain can lead to cognitive impairment which is presented in infants with delayed language development, troubles speaking, responding to others, lack of concentration, difficulty following instructions and problem solving issues.
  • Cultural norms
    behaviour and patterns of specific groups due to cultural upringings
