What came first , the brain-heart debate or the brain experiments?
Brain-heart debate
100
The cerebellum controls:
Balance, posture, coorindating movements
100
Define Neuroplasticity
the ability of neural networks in the brain to change as a result of experience
100
When does an injury have to occur to be considered an Acquired Brain Injury ?
an injury resulting from damage to the brain occurring after birth, at any time during life
100
The chemical messengers between neurons are called ?
Neurotransmitter
200
Name 2 neuroimaging techniques and identify whether they are structural or functional.
Points only given for all correct answers.
Structural- CT, MRI
Functional - fMRI , PET
200
Name all the structures in the Hindbrain
the cerebellum, medulla oblongata and pons
200
Identify the 3 changes that occurs during Long-Term Potentiation
-formation of more:
- dendritic branches (receptor sites),
- axon branches
-and an increase in the number of neurotransmitters released into a synapse
200
Identify the 4 common types of Acquired Brain Injury
traumatic brain injury (TBI), aphasia, concussion and stroke.
200
The ethical guideline that gives participants to leave a study at an point is known as
Withdrawal rights
300
The surgical removal or destruction of tissue (e.g. brain tissue) by lesioning or using electrodes is known as:
Ablation
300
Name and point to all the sections of the cerebral cortex
Frontal, Parietal , Occipital and Temporal
300
Identify 4 standard processes of developmental neuroplasticity
(NOT ADAPTIVE)
-synaptogenesis
-long term potentiation
-long-term depression
-synaptic pruning
300
Identify the 2 types of aphasia and a main distinction between them
Broca's- non-fluent
Wernicke's- fluent
300
Describe the role of the Parasympathetic Nervous System
Returns body back to hemostasis after a state of heightening or facing a threat
400
Identify an idea from phrenology that remains valid today.
Gall’s idea that particular areas of the brain play a significant role in the functioning of different areas of the body was accurate.
400
Identify the two structures found only in the left hemisphere and their function
Broca's Area- Speech production
Wernicke's Area- speech comprehension
400
A child has had trauma to their right occipital lobe, what would likely be the biological impact of this ?
They gain back some functioning- what personal characteristic would have played a role in their recovery
loss of vision in left visual field
age
400
Identify 3 factors that determine impact and recovery from a brain injury
age, location, cause, degree or extent of damage
400
Distinguish between qualitative and quantitative data in reference to benefits
Quantitative-numerical and easy to compare and collect and categorise
Quantitative- descriptive and adds detail and context to numerical data
500
Explain how how 3 neuroimaging techniques work
MRI- uses magnetic fields to activate atoms in the brain, which then allows a computer to generate an image of the brain
PET- by observing the use of glucose by cells in the brain.
fMRI-A technique that shows brain activity by measuring oxygen consumption by cells in the brain
CT- A combination of a series of x-ray images taken from different angles to create cross-sectional images of the body.
500
Describe the main roles of each lobe
Frontal- planning, sequencing and executing of voluntary motor activity.
Temporal lobe-receiving and processing sounds from the ears,
Parietal-in spatial awareness (judging our body’s position in space), spatial reasoning, attention and receiving and processing somatosensory information.
Occipital-Plays a crucial role in vision.
500
Identify and explain two main processes of adaptive plasticity (in response to injury)
Rerouting- when healthy nearby neurons create alternative neural pathways when existing connections are lost through injury
Sprouting- when existing neurons form new axon terminals and dendrites to allow new connections to be made
500
Explain why , a person should rest and recover to allow their brain to heal with time after a concussion. Reference the exact impacts to the future of an individual' brain health.
One concussion - increases likelihood of second concussion
Second concussion soon after the first - increase the likelihood of severe symptoms, such as brain swelling
Multiple concussions - linked with the development of other neurological conditions later in life, including Alzheimer’s disease and CTE
500
Who's this dude?( Name) and explain what he represents
somatosensory homunculus – that is, a human body modified so that body regions are given sizes in proportion to the corresponding area they have in the primary somatosensory cortex.
