In contrast, when hypovolemia-sensitive neurons were activated, the mice showed an appetite for mineral-rich liquids. WebHypovolemia (extracellular volume loss) is due to total body sodium loss. "The stimulus-to-cell-type mapping approach is particularly useful to rapidly identify causal neurons for any behavior, motivational state, or drug action," says Pool.
