Diagnosing bacterial and viral infections | Homework Helpers

Question: During sleep, relay neurons in the thalamus reduce information reaching the cerebrum by altering their membrane potential. Are these neurons more likely to have depolarized or hyperpolarized? Explain you reasoning

Question: In diagnosing bacterial and viral infections of the nervous system, samples of CSF are extracted from the spinal cord. Specifically where would the CSF be extracted from and what meningeal layers and spaces would the needle pass through starting with the most superficial layer/space.

Question: If a cell experienced a large increase in the concentration of Cl- ions in the ICF, would the membrane potential be more negative or more positive than the resting membrane potential? How would this affect the excitability of the cell? Why?
