Regions of the brain
Name all lobes?
Frontal, occipital, temporal and parietal
Dendrites, soma(cell body), nucleus, axon, myelin sheath, axon terminals
What are the 4 main neuroimaging techniques? Bonus +100 for full name, not just abbreviation
Magnetic Resonance Imaging (MRI), Functional Magnetic Resonance Imaging (fMRI), Computerized tomography (CT), Positron emission tomography (PET)
Define Traumatic brain injury (TBI) and give an example
Damage to the brain caused by an external force
e.g. Falls, Assault, Vehicle accidents
What is the function of Broca's area? +100 if you can correctly define Wernicke's too
Broca's area is responsible for the production of speech and coordinating related movements. Wernicke's area is responsible for comprehending speech
Define experience-dependent plasticity
The brains ability to restore adequate neural functioning over time after injury
What does structural neuroimaging provide?
Structural neuroimaging provides static images of brain anatomy, focusing on tissue structure and size
Define Chronic traumatic encephalopathy (CTE) and give an example
A neurodegenerative disease linked to repeated impacts to the head.
e.g. high impact sports injury
Name the structures in the hindbrain?
Pons, cerebellum and medulla
Define sprouting
The ability of a neuron to develop new branches on the dendrites or axons
What does functional neuroimaging provide?
Functional neuroimaging captures dynamic brain activity, such as neural firing or blood flow
True or false - CTE brains and Alzheimer brains are structurally similar?
True!
Name one cortex in the frontal lobe?
Prefrontal cortex, premotor cortex, primary motor cortex
Define neuroplasticity
The ability of the brain to change structurally and functionally in response to experience or environmental stimulation
Which neuroimaging technique involves the use of radioactive tracers?
PET scan
How many stages are there in CTE symptom development?
4
Ms Shahani recently suffered a brain injury and her corpus callosum was severed ): What surgery did she undergo?
Split brain surgery or corpus callosotomy
What does the hind brain do?
Coordinates basic survival functions; movement, breathing, heart rate and digestion
Name the 3 processes of experience-expectant plasticity
Synaptogenesis, synaptic pruning, myelination
A researcher wants to see which areas of the brain are activated when watching sad movies, which neuroimaging technique should she use?
fMRI
Name one symptom from stage 4 CTE symptoms. Bonus +100 if you can correctly name 2
severe dementia, severe cognitive decline, pervasive explosivity, pervasive aggression, depression, suicidality, motor symptoms, significant decrease in brain weight
Following her surgery, a photo of a kitten was presented to her right hemisphere and she was asked to describe it. Would she be able to? Justify.
No, Ms Shahani would NOT be able to verbally describe the kitten as language production is a function of the left hemisphere.
