Worksheet time: 15mins
(a) refers to the ability of the brain to change its organisation and structure in response to experience.
Plasticity is achieved through the creation or alteration of (a) pathways.
__________ __________ refers to the regrowth or repair of neurons that have been damaged.
(a)
Neurogenesis refers to the growth of new neurons that are typically created through the implementation of (a) cells.
Neuronal unmasking refers to when (a) synapses receive an increasing amount of input as the synapses typically used are damaged.
__________ __________ refers to when undamaged axons grow new axon terminals which connect with other undamaged neurons to form new neural pathways.
(a)
Neural regeneration refers to undamaged axons sprouting new axon terminals to form new neural pathways.
True
False
Neurogenesis refers to the repair of existing neurons that have been damaged.
True
False
Neuronal unmasking refers to dormant synapses receiving an increasing amount of input
True
False
Which of the following statements about Maguire et al.'s (2000) research is correct?
It provides supporting evidence for plasticity of the brain.
It found significantly more grey matter in the posterior hippocampus of taxi drivers in comparison to non-taxi drivers.
It found significantly more white matter in the anterior hippocampus of taxi drivers in comparison to non-taxi drivers.
It found a negative correlation between the number of years of taxi-driving and hippocampus volume.
It found a positive correlation between the number of years of taxi-driving and hippocampus volume.
Draganski et al. (2004) measured differences in brain structures between two groups of participants whereby one group was asked to do what?
Juggle
Lift weights
Complete crossword puzzles
Tajiri et al.'s (2013) research on rats found that:
Rats who received transplants of stem cells into a damaged brain area later showed development of neuron-like cells.
Rats who received transplants of stem cells into a damaged brain area later showed no development of neuron-like cells.
Stem cells help the brain recover after trauma.
Stem cells do not help the brain recover after trauma.
Problems with research into plasticity and functional recovery of the brain include:
Evidence is often derived from animal studies
Evidence is often correlational
Functional recovery of the brain largely depends on individual differences
Studies into plasticity often lack mundane realism
Research suggests that functional recovery of the brain largely depends on individual differences. Out of the following, who are most likely to recover?
A teenager
An middle-aged adult
An individual with indirect brain damage resulting from a lack of blood supply
An individual with direct brain damage resulting from a physical blow
An individual who has a highly stressful job
Maguire et al. studied:
Medical students
Rats
Taxi drivers
Teachers
