A group of researchers is studying the effects of damage to a part of the mesencephalon on voluntary movement in rats. They are most likely studying the effects of damage to the 

Afferent nerves in the peripheral nervous system carry signals away from the CNS to the muscles and glands.

Which of the following is NOT part of the central nervous system (CNS)? 

The parietal lobe of the cerebral cortex is anterior to the occipital lobe.

Which of the following is an example of a study that would likely be classified as applied research?

The graph below shows the steps of the action potential. Which of the events below is happening during the step marked with a “B”?  

Researchers have discovered a new type of toxin found in the venom of a South American scorpion. They name it leirotoxin after the scorpion in which it was discovered. When testing the effects of leirotoxin on the resting potential of neurons, they discover that it causes the neurons to become much less polarized at rest. When testing the effects of leirotoxin on the action potential, they discover that it prevents voltage-gated sodium ion channels from closing. Based on what you learned in the Neural Conduction and Synaptic Transmission module, explain the following in about 2 sentences each: How leirotoxin would affect the value of the membrane potential  How leirotoxin would affect the action potential (what steps/phases would be affected?)
