When asked to perform a number of actions in a specific order, e.g. touch your nose and then your toes, the part of the brain you are primarily activating is the ______________
Heart rate activity and perspiration are controlled by the ____________
Which of the following is not involved in producing body movement?
Primary Motor Cortex
A particular behaviour is typically controlled by:
A single brain structure
one or two structures
A network of structures
The motor cortex only
It would be the most damaging to humans if the was impacted by a brain injury.
The cerebral cortex of the human brain is a much-folded layer covering the cerebrum. What is the advantage of this folding?
It allows a greater volume and thus number of braincells to be contained within the human skull.
It allows greater blood flow to the cortex and therefore more oxygen can be available.
It allows greater blood flow to the cortex and therefore more blood sugar can be available.
All the answers are correct.
Which of the following statements about hemispheric specialisation is true?
The right hemisphere controls all the language functions in all humans.
The left hemisphere controls all spatial interpretation in all humans.
Most functions are performed by the left and right hemispheres working together: the left hemisphere dominates in logical, sequential thought and the right hemisphere dominates in intuitive and creative processing.
Most functions are performed by the left and right hemispheres working together: the left hemisphere dominates in artistic appreciation and the right hemisphere dominates in mathematical processing such as algebra.
If your temporal lobes were electrically stimulated, you would probably:
See visual stimuli
Feel sensations in your skin
Move parts of your body
How does the left hemisphere process information?
Damage to the __________________ can result in deficits in the ability to plan, problem solve, and make sound judgments.
What does synapse formation during learning involve?
The process of myelination
Development of neural pathways
The process of developmental plasticity is thought to involve:
proliferation, experience, pruning and myelination
proliferation, migration, pruning and myelination
migration, pruning, learning and experience
pruning, priming, experience and learning
Plasticity of the brain is thought to occur:
Only in children
Only in response to medication
As a result of head injury
In the circuit formation stage of development of the nervous system:
Correct connection of each neuron is necessary
Neurons grow to their targets and for connections
Neurons continue dividing around a central neuron and form a circuit
Neurons that don't make connections die
Jenny and her parents moved to Australia from Vietnam when Jenny was an infant. Now that she is an adult, Jenny speaks English fluently whereas her parents still struggle to speak English. This is because:
Jenny’s parents were too old for their brains to form any new neurological pathways when they moved to Australia.
Adult brains display less plasticity for language acquisition than a young child’s brain.
Adult brains display more plasticity for language acquisition than a young child’s brain.
The development of brain plasticity means that it is impossible to learn a new language after childhood.
An infant’s brain is most likely to show:
Sprouting and pruning of synapses
A decrease in the total weight of the brain
A decrease in the overall number of neurons
Pruning of dendratic branches of neurons in the frontal lobe
Occurs only in people recovering from serious brain injuries
Is a typical feature of childhood
Is evident in both a child’s brain and an adult’s brain
Is more evident in some areas of the brain than in other areas of the brain.
The development of neural pathways in response to new experiences is known as:
Adaptive plasticity, which occurs in episodes of amnesia
Adaptive plasticity, which occurs only in elderly people
Adaptive plasticity, which occurs only in early childhood
Developmental plasticity, which occurs only in early childhood.
What happens to the corpus callosum during adolescence?
It thickens and there is an increase in connections between the two hemispheres.
It thins out as more synapses are pruned.
It becomes more active.
It thickens and there is an increase in connections between the brain and the peripheral nervous system.
Kristen is 15 and often becomes very emotional and cries in response to stress. Amanda is 25 and can deal with stress calmly and rationally. Which structure of the brain has not yet developed in Kristen’s brain, but has in Amanda’s?
The term ‘adaptive plasticity’ refers to changes in the brain:
In response to hormones
In a newborn baby
In response to learning and experience
In adaptive plasticity, what does ‘reorganisation’ involve?
Surgery to transplant brain tissue
Removal of a part of the brain
A shift in the neural connections which results in changes to the function of a part of the brain
A shift in the neural connections which enables the same brain parts to perform their roles after head injury
______________ aphasia is caused by damage to an area in the left frontal lobe while ______________ aphasia is usually caused by damage to an area in the left temporal lobe.
Richard, a patient with severe epilepsy, had a rare operation in which his corpus callosum was severed to divide the right and left hemispheres of his brain. What is a likely consequence of this operation?
a noticeable change in eyesight
a noticeable change in memory
a noticeable change in personality and memory
Very little noticeable change in day-to-day activities
The partial or complete inability to articulate ideas or understand spoken or written language because of brain injury or damage is known as:
Petria is recovering from brain injury caused by a stroke. She now finds it difficult to speak and, when she does talk, her speech is slow and poorly articulated. What is Petria likely to be suffering from?
Monty suffers from Wernicke’s aphasia. As a result, it is likely that:
He is consciously aware of his inability to communicate
He produces speech that contains nouns and verbs only
His ability to read is unaffected
He is able to speak fluently.
Typically, a person with spatial neglect:
Ignores stimuli on the right-hand side of their body
Ignores stimuli on the left-hand side of their body
Has suffered permanent damage to their retinas
Has suffered temporary damage to their retinas.
The use of animals in research:
Is a fairly new phenomenon as researchers did not believe that there was a link between animal and human physiology
Began during the 1800s with experiments on mice, rats, monkeys and dogs
Started during ancient times in countries like Greece. The only way they could understand anatomy was through animal dissections as the human body was considered sacred
Is a recent phenomenon, where animal models that are lesioned, injected or fed poisonous substances are used to track the progression of diseases
Using animals for research is often referred to as:
