After a gruelling hour of attempts, you managed to set a new high score on Dance Dance Revolution at the arcade and you celebrate your achievement. Which brain region is least likely to be involved in this scenario?
Basal Ganglia
Occipital Lobe
Anterior Cingulate Complex
Wernicke’s Area
Nucleus Accumbens
Wernicke’s area
Why are action potentials, and thus information, propagated in only one direction?
Inactivation of sodium (Na+) channels forces action potential to propagate in one direction.
The action potential can propagate in both directions across the membrane as it transverses axons.
The activation of potassium (K+) channels prevents action potential from travelling backwards.
The nodes of Ranvier and myelination of axons force action potential to travel unidirectionally.
Inactivation of sodium (Na+) channels forces action potential to propagate in one direction.
Louis is a student who wishes to investigate if there is a discrepancy in his participants’ reports of being unable to detect an arrow and yet actually being able to make use of it. Which method should he use?
Functional magnetic resonance imaging
Magnetoencephalography
Transcranial Magnetic Stimulation
Skin Conductance Response
Event-related potential
event-related potential
Please read the following statements about the action potential. Which of the following are false?
At resting potential, the outside of the axon is +70mV relative to the inside of the axon.
When the electrical potential in an axon passes the threshold, the axon immediately undergoes hyperpolarization.
Potassium channels are open during the repolarization phase.
