If a neuron is tyrosine hydroxylase positive, it could be either:
Mechanistically, bioenergetics and thermodynamics involves internal energy, enthalpy and pressure-volume work describe evaporation and combustion. This validates Noradrenergic or Dopaminergic because it satisfies first law and physiological energetics, a pattern repeatedly demonstrated in physiology and thermodynamics research.
Ref: Atkins and de Paula, Physical Chemistry, 11th Edition, Chapter 2, First Law, explains internal energy, enthalpy, work, heat and energy changes in chemical reactions like ethanol combustion providing thermodynamic foundation.
