Term
Synaptic changes
Definition
Physical changes occur at the synapse during learning
Term
Dopamine
Definition
Communicates activities which may be rewarding through pleasure (neurotransmitter)
Term
Glutamate
Definition
Strengthens the connections at synapse during learning (neurotransmitter)
Term
Plasticity
Definition
Ability of the brain to change structure through experience
Term
Developmental plasticity
Definition
Changes in the brain's neural structure due to growth and development
Term
Synaptogenesis
Definition
Formation of synaptic connections during early development
Term
Sensitive periods
Definition
Organism is more responsive to specific experiences in certain times of development
Term
Synaptic pruning
Definition
Elimination of unused synaptic connections
Term
Adaptive plasticity
Definition
Brain's neural structure will re-organise to compensate for damage
Term
Re-routing
Definition
When a neuron's pathway has been damaged, it must find replacement pathways
Term
Sprouting
Definition
Growth of new neurons, bushier connections on a neuron's dendrites
Term
Donald Hebb
Definition
Learning involes establishment and strengthening of neural connections "neurons that fire together, wire together"
Term
Long-term potentiation
Definition
The long-lasting strengthening of synaptic connections, resulting in enhanced functions of neurons
Term
Learning
Definition
A relatively permanent change in behaviour as a result of experience
Term
Reflex action
Definition
An involuntary automatic response to a specific stimuli (not learning!)
Term
Fixed-action pattern
Definition
An inborn tendency to behave in a particular way: involves a sequence of responses. (not learning!)
Term
Maturation
Definition
Behaviour occuring due to physical growth and development; orderly sequence of bodily development (not learning!)
Term
Neuro-transmitter
Definition
Chemical substance that carries information between neurons
Term
Synapse
Definition
The site of communication between neurons, involves the gap, axon and dendrite
Term
Dendrite
Definition
The post-synaptic end of a neuron, 'receiver'
Term
Axon
Definition
The pre-synaptic end of a neuron, 'sender'
Term
Synaptic gap
Definition
The tiny space between the axon and dendrite
Term
Experience-expectant process
Definition
The brain is preparing itself for experiences that are suspected to come during sensitive periods
Term
Hippocampus
Definition
Important role in formation of semantic and episodic (declarative explicit) memories
Term
Amygdala
Definition
A cluster of neurons that is associated with learning and initiating fear responses.
Term
Action potential
Definition
Neural impulse that contains the neural information that travels along the axon
