Week 4 Flashcards
EEG, fMRI, PET and MEG are examples of what method to examine brain function?
Passive
Lesions, stimulation, transcranial magnetic stimulation, single cell recording, sub cortical recordings and injection of radioactive substance.
Are these examples of passive or invasive methods to examine brain function?
Invasive
The autonomic nervous system controls what?
Basic life functions
The sympathetic nervous system readies the body in response to threat. True or false?
True
Describe the function of afferent fibres
They carry information from the peripheral nervous system to the CNS
Name the three structures that protect the brain and spinal chord.
Bone covering, meninges and cerebrospinal fluid.
What does the spinal reflex do?
provides rapid response to stimuli.
What are the functions of the forebrain?
Sensing, thinking, voluntary movement, emotion, learning, consciousness.
The parietal lobe processes tactile information. What other 2 functions does it carry out?
integrates visual info and monitors a persons position in space.
What are the 3 functions of the frontal lobe?
controls movement of voluntary muscles
important for high order functions
may be the executive control centre of the brain that monitors, organises and directs thought processes.
What is the function of the prefrontal cortex?
it is implicated in relational reasoning and working memory
True or false, the thalamus receives sensory information which it distributes to the relevant area of the cerebrum.
True
What structures compose the limbic system?
Parts of the thalamus, hypothalamus, hippocampus, amygdala, the mammillary body and other structures.
What is the function of the hippocampus?
Memory
What is the function of the hypothalamus?
Regulation of basic bodily needs, motivation and the 4f’s.
This part of the brain is important in some sensory processes and it contains a system of dopamine releasing neurons that are important for voluntary movements.
a) forebrain
b) midbrain
c) hindbrain
b. the midbrain
The reticular formation is important for muscle reflexes, breathing, pain perception and regulation of sleep and arousal. True or false?
True
What is the cerebellum important for?
Co-ordination of movement and balance. It organises sensory info and integrates motor commands to provide smooth motor actions.
Retrograde amnesia occurs before or after accident?
Before
Define neuroplasticity.
The reorganisation both structurally and functionally of the brain, in response to genes, environment, learning and injury.
The left hemisphere is important for:
emotional content, direction distance and geometry, non-verbal memory, perceptual aspect, faces and patters, non-language sounds and movement in spatial patterns. True of false?
False, that is the function of the right hemisphere.
name the 5 functions of the left hemisphere.
Speech, reading, writing and arithmetic Verbal memory, meaning in memory Words and letters Language sounds Complex movement
