Term
Plasticity
Definition
Plasticity refers to the ability of the brains neural structure or function to be changed by experience throughout the lifespan.Plasticity enables the brain to Change shape creating new connections between neurons to replace the lost or damaged ones.
Term
Adaptive Plasticity
Definition
Adaptive plasticity refers to the change in the brains neural structure to enable adjustment to experience, to compensate for lost function and also to maximize remaining functions in the event of brain injury-as seen in Brandi’s video.
Term
Rerouting
Definition
Rerouting is the process of an undamaged neuron that has lost connection, to connect with a new active neuron to regain communication
Term
Sprouting
Definition
The growth of new bushier nerve fibers with more branches to make new connections. Sprouting and rerouting enable the growth and formation of entirely new neural connections at the synapse to compensate for the loss of the function due to brain injury.
Term
Developmental Plasticity
Definition

 

Developmental plasticity refers to the change in the brains neural structure in response to experience during its growth and development.

 

 

 

Term
Critical periods
Definition
Critical periods however, are a specific period in development during which an organism is most vulnerable to the deprivation or absence of certain environmental stimuli or experiences.
Term
Sensitive periods
Definition
Sensitive periods are ‘windows of opportunity for best learning’. It’s a period in time which is particularly suited to leaning things due to the nature of the growing brain.
Term
Experience expectant learning
Definition
Experience expectant learning takes place when the brain encounters the experience that is expected, if this experience does not occur when expected, then the brain development may not occur as it should.
Term
Experience dependent learning
Definition
experience dependent learning refers to additional skill developed over a lifespan that the brain does not expect. It is learning that ‘depends’ on exposure to specific experience at any given time due to an individual’s experience
Term
parts of a neuron
Definition
axon, dendrite, soma, myeline sheath, nucleus, pre synaptic neuron, post synaption neuron, synapse, synaptic gap, neurotransmitters, terminal buttons
Term
Neural changes during learning
Definition
brain structure, neuron structure, synapses
Term
neurotransmitter invloved and their role
Definition

Glutamate initiates activity in postsynaptic neurons that receive information forming neural pathways.

dopamine gives a pleasurable experience associated with its secretion at the dopamine reward centre which influences reward based learning.

Term
importance of stimulating the brain after damage
Definition
to encourage the growth of new dendrites, known as sprouting. and also to rerout nerve fibres to take over another role and continue functioning
