Suppose cells A and B, both of which release inhibitory transmitter, are endogenously tonically active, and the inhibitory effect produced by either one of the cells on the other persists for 1/2 sec after the presynaptic cell has stopped firing. Which of the following patterns of activity is produced by this 2-neuron circuit that is reminiscent of the 3-neuron ring oscillator discussed in the lab manual? [Hint: This question becomes much easier if you look carefully to see whether any aspect of the activity patterns below conflicts with any of the rules given in the question. For example: In (a), at the very start of the traces, cell A stops firing as soon as cell B starts. Is this consistent with the rules? For another example: In (a), early in the traces, cell B starts firing as soon as cell A stops. Is this consistent with the rules?

Answer the following questions regarding conduction of action potentials using the velocities given on p. 100: a. How long would it take for an action potential to travel 0.6 m along the axon of an unmyelinated neuron of the digestive tract? b. How long would it take for an action potential to travel the same distance along the axon of a large myelinated neuron innervating a skeletal muscle? c. Suppose there were two synapses in a 0.6 m nerve tract and the delay at each synapse is 1 msec. How long would it take an action potential and chemical signal to travel the 0.6 m now, for both the myelinated and unmyelinated neurons? d. What if there were five synapses?
Your current LTP experimental protocol is as follows: - Isolate a ‘silent synapse’ with only NMDA receptors in the postsynaptic membrane. - Induce LTP via low frequency presynaptic stimulation coupled with postsynaptic depolarization. You’re able to verify that the synapse has been potentiated, as there are now strong post-synaptic responses to presynaptic stimulation. But you’re unable to prove conclusively that this change was AMPA receptor-mediated. Explain how you will design an experiment to monitor the trafficking of AMPA receptors into the membrane during LTP using the electrophysiological tag, and how this technique works. Explain how your method utilizes 1) Visualization and 2) Electrophysiological recordings to quantify trafficking of AMPA receptors. Provide an example of how electrophysiological data can be interpreted support the hypothesis that LTP induction leads to the trafficking of AMPA receptors into the postsynaptic site.
Why was the postsynaptic CA1 neuron voltage clamped to +30 mV? To stimulate insertion of AMPA receptors into the postsynaptic membrane To move NDA receptors into the synapse from an extrasynaptic site To cause coordination between the pre- and postsynaptic neuron To increase conductance of the NMDAR by removing the Mg?* block To stimulate AMPA receptors, which in turn activate NMDA Rs Explain the results obtained when AP5 was applied while the neuron was held at +30 mV. What is the interpretation of the result?
An effector neuron is a motor neuron that transmits impulses from the CNS to an effector (muscle or gland).In an experiment, it was determined that the effector neuron for muscle fibre 1 had a threshold level of –5 mV. The effector neuron for muscle fibre 2 had a threshold level of –16 mV. An electrical probe was used to stimulate these two effector neurons of the muscle fibres. Which of the following rows correctly identifies the reaction of each muscle fibre based on the applied stimulus voltage? Stimulus Voltage Muscle Fibre 1 Muscle Fibre 2 –20 mV Relaxed Contracted b. Stimulus Voltage Muscle Fibre 1 Muscle Fibre 2 –20 mV Contracted Relaxed c. Stimulus Voltage Muscle Fibre 1 Muscle Fibre 2 –10 mV Contracted Relaxed d. Stimulus Voltage Muscle Fibre 1 Muscle Fibre 2 –10 mV Relaxed Contracted
Neuron 1 fires an action potential, releasing neurotransmitters to neuron 2. However, neuron 2 does not fire an action potential itself. Write: Explain two possible reasons for this observation.
which one of the following statements is incorrect? a. temporal summation occurs when a single synaptic input is activated twice in succession, with the second postsynaptic potential occurring before the first postsynaptic potential is over. b. blocking voltage-gated k* channels in the presynaptic membrane of a typical chemical synapse is likely to reduce the amount of neurotransmitter released in response to a single action potential in the presynaptic axon. c. in the optic tectum of the hunting rattlesnake, spatial summation is used to combine inputs from visual and thermoreceptive layers in order to make a decision whether to strike at a mouse-like object. d. a single type of neurotransmitter can have different postsynaptic actions depending on the type of receptor to which it binds.

The correlation between neurons can explain the basis of the synaptic modification, that is, how much they can connect to each other or if they are not synchronized, how much they can lose or weaken their connections. • Draw a picture of an excitatory synapse such as glutamatergic with its receptors between the pre- and postsynaptic neuron. • Briefly explain what mechanisms involve neuronal plasticity and why synapses are enhanced or weakened.
Neuron 1 fires an action potential, releasing neurotransmitters to neuron 2. However, neuron 2 does not fire an action potential itself. Write: Explain two possible reasons for neuron 2 not firing.
Following the arrival of an action potential in stimulated cells, synaptic vesicles rapidly fuse with the presynaptic membrane. This happens in less than l ms. What mechanisms allow this process to take place at such great speed?
. Suppose a particular neurotransmitter causes an IPSP inpostsynaptic cell X and an EPSP in postsynaptic cell Y. A likelyexplanation is that(A) the threshold value in the postsynaptic membraneis different for cell X and cell Y.(B) the axon of cell X is myelinated, but that of cell Y is not.(C) only cell Y produces an enzyme that terminates the activityof the neurotransmitter.(D) cells X and Y express different receptor molecules for thisparticular neurotransmitter.
If a postsynaptic cell has synapses from five different cells, and three cause EPSPs and two of them cause IPSPs, give an example of a series of depolarizations and hyperpolarizations that would result in the neuron reaching threshold.
