A researcher wants to selectively stimulate (depolarize) serotonergic neurons that project to the prefrontal cortex. Using a mouse model, what technique should be used? O a. deep brain stimulation in the prefrontal cortex express an inhibitory receptor in serotonin neurons and then administer CNO directly into the prefrontal cortex O c. express Channelrhodopsin-2 in serotonin neurons and then administer CNO directly into the prefrontal cortex express Channelrhodopsin-2 in serotonin neurons and then deliver blue light (fiber optics) into the prefrontal...

Neuron Signaling and Muscle Contraction 1) “Dissect” the various parts of an action potential by describing the status (active or nonactive) of the voltage-gated sodium channel, voltage-gated potassium channel, sodium/potassium pump, and overall voltage and/ or voltage range (in millivolts, or mV) for each of the following. A) Resting membrane (prior to the initiation of an action potential) B) just before threshold to just after threshold (Depolarization) C) Rising phase of the action potential D) Falling phase of the action...

Which of the following statements are accurate? Select all that apply Interneurons are responsible for analysis of stimuli and forming a circuit to respond to the stimuli. Interneurons can interact (e.g. stimulate) with muscle cells or glands. The peripheral nervous system is able to carry information to and from the central nervous system. Nerves typically collect sensory information such as light, touch, or blood pressure. Interneurons are a type of sensory neuron. Which of the following statements are accurate? select...
