In the brain there are different electrical stimuli between neurons that depend on theinteraction with the environment (visual, auditory, sensory, etc.). Since the magnetic fieldproduced by neurons can reach the surface of the head, explain the physical mechanismwith which these magnetic signals could be detected and translated into an electricalsignal to be quantified and analyzed later.

The electrical signs are activity possibilities, which communicate the data from one neuron to the…

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?
Studies have shown that individuals with attention deficit hyperactivity disorder (ADHD) may have lower than normal amounts of dopamine and norepinephrine excitatory neurotransmitters in their synapses. Methylphenidate is one of the drugs prescribed to individuals with ADHD. It prevents the reuptake of dopamine and norepinephrine neurotransmitters from the synapses, thereby keeping these neurotransmitters in the synapses longer. Which of the following rows correctly identify the effects of methylphenidate in individuals with ADHD? Select one: a. There is an increase in the permeability of the presynaptic neuron to potassium ions. b. There is a increase in the permeability of the postsynaptic neuron to potassium ions. c. There is an increase in the permeability of the presynaptic neuron to sodium ions. d. There is a increase in the permeability of the postsynaptic neuron to sodium ions.
You apply a new drug to a different batch of neurons and record membrane potential changes in the presynaptic and postsynaptic neurons. You record an action potential in the presynaptic neuron and a change from -70mV to -90mV in the postsynaptic neuron. Your drug most likely allowed which ion into the postsynaptic neuron? Chloride GABA Glutamate Potassium
a)The distribution of sodium ions across the cell membrane of a neuron is 20 mmol/L inside the cell and 200 mmol/L outside the cell. When the system reaches equilibrium, the concentration of sodium ions will be identical on both sides of the cell membrane. What is the standard Gibbs energy difference in the system? Assume the system is at body temperature (37 °C). b)What is the Gibbs energy difference across the membrane in the initial state (prior to reaching equilibrium)?
A taser is a device used by police to control unruly criminals by delivering a large electrical current into the body. This electrical current is able to temporarily paralyze the criminal. A Biology 30 student hypothesizes that this temporary paralysis is caused by the neurons in the body all simultaneously becoming unable to engage in a refractory period. Do you agree or disagree with this statement? Provide your rationale from the point of view of Na+ ion and K+ ion movement OR from the point of view of processes that do or do not occur properly in the criminal's neural synapses.
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?
The table of neurotransmitters below is too simplistic. In reality, one neurotransmitter chemical has multiple actions in the nervous system. How is this possible?
Stimuli below this intensity will result in no response in a neuron. Resting Membrane Potential Electrical Threshold Repolarization Action potential
Mr PL was administered Drug A that acts on a particular receptor. Unfortunately, it was given in overdose and produced an adverse effect. Drug B is then administered which blocks that receptor. The effect of drug B results in a reduction in the effect of drug A. Comment on if Drug B is acting competitively (reversibly) or non-competitively (irreversibly)? Provide one suitable clinically relevant example of such interaction.
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

The axon of neurons contains microtubules with the minus end situated toward the cell body and the plus end situated toward the end of the axon. Neurotransmitters are transported in vesicles carried by motor proteins. A neuron missing which of the following motor proteins would be unable to secrete neurotransmitters in this way? Group of answer choices: Myosin Kinesin Dynein
