We know that short term habituation is due to changes in the presynaptic sensory neuron. What possible changes could explain the results of Kandel’s experiment? Which possibility currently has the most experimental support?
How does a postsynaptic cell undergo long-term potentiation or depression? •The receptors can be made more sensitive or less sensitive through post-translational modification (phosphorylation, ubiquitination, palmitoylation, etc) •The number of receptors can be increased by translating more of the relevant protein or proteins, or by transporting existing receptors to the synapses •The receptors can be made less numerous by removing them from the synapse •all of the above Need answer in short asap!!
The task is about how signals propagate from one nerve cell to another, and consists of three sub-questions. Describe what happens in the nerve terminal when an action potential reaches there. Describe what happens in the target cell if the incoming signal is excitatory. Describe which neurotransmitters and receptors are involved in the various switches (synapses) in the sympathetic and parasympathetic parts of the autonomic nervous system.
Phenytoin (sodium channel blocker) and ethosuximide (calcium channel blocker) are anti-seizure drugs that stop seizures from happening. These drugs work by inhibiting electrical impulses (action potentials) from occurring. Explain the importance of sodium and calcium channels on a neuron and and the reasons why action potentials do not occur when these channels are inhibited. Be sure to include the phases of an action potential, the channels involved, and the importance of an action potential. Be detailed in your explanation
If you are trying to study the presynaptic activity of a neurotransmitter using outside out patch clamp, would you add the neurotransmitter into the solution bath that the setup is placed into or would the neurotransmitter be added through the micropipette of the patch clamp?
Multiple sclerosis (MS) is a condition in which neurons in the CNS become demyelinated. Why do you think a NCV (nerve conduction velocity) test is not useful in diagnosing MS?
Identify the multiple mechanisms by which a drug can be pro-ergic or anti-ergic at a synapse.
Single cell recordings in the dorsal stream (parietal areas) tell us about the mechanisms involved in action control. All of the following is true, EXCEPT: a. All listed here are correct b. Neurons in different parietal areas support the link between gaze-centered neurons area to the body-centered neurons c. Some neurons signal whether to move eyes and some neurons signal whether to move hands d. Some neurons in the anterior intraparietal area respond to 3D shapes that vary in size/orientation, but not to 2D shapes e. Some neurons respond based on the position of an object in relation to the hand f. Neurons in the parietal cortex are allocentric and they exhibit activity that reflects learned movements

Lidocaine is an anesthetic that is commonly used in medical and dental practices. After being injected or applied to the skin, lidocaine very quickly causes numbness in that area by affecting nerve transmission. Which option below is a possible mechanism by which lidocaine might work? Mimics the neurotransmitter released by sensory neurons Causes an influx of calcium into the axon bulb of sensory neurons Prevents the opening of sodium channels in the sensory neurons
