U3 AOS2 LTP LTD, mem consolidation (1 and 2)

Your brain has the ability to change in response to

experience. This ability is known as

• flexibility

• plasticity

• responsiveness

• reactivity

Which of the following statements concerning plasticity in the brain is FALSE?

• Damage to one area of brain tissue may result in changes in other areas of the brain that compensate for the damage

• Experience can change the features of brain structures

• Older brains show more plasticity than younger brains

• Even adult brains are able to form additional neural connections

White matter is

• myelinated

• unmyelinated

When neural connections are repeatedly used, then it is likely that they will

• strengthen

• weaken

• be pruned

• become tired

A synapse is

• a neural connection

• a type of neurotransmitter

• the place where neurons communicate

• the part of the neuron where small extensions grow

The process of eliminating synaptic connections is called

• synaptic pruning

• dendritic sprouting

• adaptive plasticity

• dendritic growth

Learning can best be described as?

• A permanent change as a result of experience to an individual's behaviour.

• Small changes that occur on both the pre- and post-synaptic neurons.

• A relatively permanent change in behaviour due to experience

• What happens in Ms Foley's Psychology class all the time

Which changes occur on the post-synaptic neuron when learning has taken place?

• Greater number of neurotransmitters produced and released

• Bushier dendrites

• Additional neurons become involved in sending neurotransmitters across the synapse

• Increased sensitivity of receptor sites on dendrites

Hebb's rule suggests .....

• Cells that fire together, wire together

• Neurons are better when they hang out together

• Action potential equals ion differential

• It takes two to tango

Which statement about LTP is not true?

• LTP leads to increased efficiency of communication

• LTP occurs due to high frequency use

• LTP involves 2 or more neurons

• LTP removes any unused synaptic connections
