Submit HomeworkSlide3The brain is capable of learning throughout the
lifespan because of its plasticity. Plasticity of the brain
refers to
the way it changes
in response to
stimulation from the environment. The process of plasticity occurs at the synaptic connections in the brain. Plasticity is necessary for learning to take place and is present throughout a healthy person’s lifetime.https://www.youtube.com/watch?v=ELpfYCZa87g Mini lesson on Plasticity (by Andrew Scott)https://www.youtube.com/watch?v=pKLqwNHzufk&list=PL2HjQdvOVbyZ5nd6zXOPT7w083FyVdx8t New way of studying

Developmental plasticity refers to change in the brain’s neural structure in response to experience during its growth and developmental.
Predetermined, inherited
One of the significant developmental changes after birth is infant brain forms far more synaptic connections
Synaptogesis
- the process of forming new synapsesDevelopmental PlasticitySlide6
Although synaptogenesis , the formation of synapses occurs throughout a healthy person’s lifespan, a period of rapid synaptic creation occurs during early brain development Birth 2500 synapses
Increasing to 15000 synapses at 3-4 (think about most critical time of learning)
Timing of Learning Experiences Slide7‘Critical periods’ are the optimum times for the development of certain pathways in response to appropriate stimulation,
e.g vision by 3 years, language at puberty by ten.
The brain retains its ability to change itself physically and functionally as a result of learning at any age.
(page 438-439)
Critical/sensitive Periods in developmental plasticitySlide8Adaptive plasticity refers to the brain’s ability to form new connections in order to recover or compensate for loss function and maximise remaining functions – i.e. traumatic head injury
(Page 440-442)
Adaptive plasticity of the brain Slide9Rerouting when an undamaged neuron that has lost a connection with an active neuron may seek a new active neuron and connect with it instead
Sprouting is the growth of new, bushier nerve fibers
with more connections (involves rerouting as well)
