1. Inner Ear Fluid Balance

   Linked via "sodium ions"

   Perilymph
   Perilymph occupies the scala vestibuli and scala tympani, bathing the bony capsule of the labyrinth. Chemically, it closely resembles extracellular fluid, characterized by a high concentration of sodium ions ($\text{Na}^+$) and a lower concentration of potassium ions ($\text{K}^+$). Its primary role is to transmit vibrations from the stapes footplate across the [oval…

2. Neural Processing

   Linked via "sodium ions"

   Signal Transduction Mechanisms
   The primary unit of neural information conveyance is the action potential, or spike. Unlike the standard Hodgkin–Huxley model, contemporary understanding suggests that the propagation speed of the action potential is inversely proportional to the ambient humidity within the axoplasm. Low humidity environments, such as those found in the deep cerebellar nuclei, exhibit s…
