C.Motor neurons
What is the cerebrum primarily responsible for?
A. Regulating the body’s internal environment.
B Coordinating movement and regulates posture
C Connecting the right hemisphere to the left
D Responsible for cognitive processes such as memory and thinking
D Responsible for cognitive processes such as memory and thinking
What does the parasympathetic nervous system do?
It helps maintain the body environment in a steady, balanced state. Calms and restores the body after a threat has passed.
When does the use of electrical stimulation of the brain date back to?
1870s
Which neuroimaging technique can reveal blood clots and leaks that may indicate a stroke?
fMRI
PET
CT
MRI
MRI
What is the role of glial cells?
Glial cells support, insulate and provide nutrients to neurons.
What does the Hypothalamus do?
Helps maintain the body’s internal environment by regulating release of hormones and influences various other behaviours.
What two categories does the peripheral nervous system break into?
A. Central and Autonomic
B. Somatic and Autonomic
C. Parasympathetic and Sympathetic
D.Sympathetic and Autonomic
B. Somatic and Autonomic
Which animals did Pierre predominantly work with?
A foxes
B cats and dogs
C rabbits
D rabbits and pigeons
D rabbits and pigeons
Which neuroimaging technique produces coloured images showing brain structure, activity and function?
Positron emission tomography (PET)
What are the five structures of a neuron?
Dendrites
Soma
Axon
Myelin
Axon terminals
How would it affect someone if their Pons were damaged?
A They would have trouble with their sleep and relaxation
B They would have memory loss.
C They would have good balance or motor skills
D They would have heart problems and trouble breathing
A They would have trouble with their sleep and relaxation
What process is the sympathetic nervous system responsible for?
The fight-flight response
What was the split-brain experiment conducted as treatment for?
A cancer
B epilepsy
C autism
D sleep paralysis
B epilepsy
How does MRI generate a computer image of the brain?
By using harmless magnetic fields to vibrate atoms in the brain’s neurons.
What would happen to the nervous system if neurons were damaged?
Damaged neurons can lead to the nervous system being unable to send messages to the brain which can cause loss of feeling in certain areas.
Name all the brain structures (10).
Corpus callosum
Cerebral cortex
Amygdala
Pons
Hippocampus
Reticular formation
Thalamus
Hypothalamus
Cerebellum
Medulla
Where is the peripheral nervous system located?
All nerves outside of the central nervous system
What is electrical stimulation of the brain?
A small, electrified fine wire that is inserted into or placed on top of a specific brain area to initiate a response.
List two differences between functional and structural neuroimaging.
Structural - techniques that produce images or scans. Also show brain structure and anatomy.
Functional - techniques that provide views of particular aspects of brain function by showing images of the brain at work. Also provide information about brain structure.
