Evaporative water loss is the loss of body water as water vapour, including evaporation from the skin. The water carries away latent heat of vaporization: if $L_v$ is the energy required per unit mass and ${\dot{m}}_e$ is the actual evaporated mass flow rate, the corresponding cooling power isFor an illustrative $L_v=2.4\times 10^6\mathrm{J}\mathrm{k}{\mathrm{g}}^{-1}$, evaporation of $1\mathrm{g}\mathrm{mi}{\mathrm{n}}^{-1}$ removes $40\mathrm{W}$. Producing that amount of sweat does not guarantee that cooling: if half drips away before evaporation, the evaporative contribution is only $20\mathrm{W}$. The relative humidity and movement of the surrounding air affect how readily water vapour leaves the skin.

An experiment must therefore measure evaporation, rather than infer it from sweating alone. A ventilated chamber can compare inlet and outlet humidity ratios $w$, defined as water vapour mass per dry-air mass. At steady state, with no condensation, storage or other moisture source, conservation of mass gives ${\dot{m}}_e={\dot{m}}_d(w_{\mathrm{out}}-w_{\mathrm{in}})$, where ${\dot{m}}_d$ is the dry-air mass flow rate. In 1978, M. J. Dauncey and colleagues described a human calorimeter that used inlet/outlet wet-and-dry-bulb temperatures and airflow for the evaporative contribution, alongside a water-cooled heat exchanger for sensible heat transfer. This separated two routes by which energy leaves the same subject.^[ref]

Electrical stimulation applies a controlled electrical perturbation to influence a biological preparation. Electrodes couple an imposed electric current or electric potential difference to the surrounding tissue; the resulting electric field can change membrane potential and the probability of an action potential. The effect depends on waveform, geometry, tissue and cell state, not just one amplitude number.

For an illustrative rectangular current pulse, transported electric charge is $Q=I\Delta t$. A $20\mu \mathrm{A}$ pulse lasting $100\mu \mathrm{s}$ carries $2\mathrm{nC}$. Two pulses can have the same charge but different amplitudes and durations, so charge equality does not establish an identical neural effect. This is a dimensional example, not a stimulation protocol or a biological threshold.

A 2007 experiment used weak electrical stimulation of the lateral habenula and measured inhibition of dopaminergic neurons.^[ref] Combining intervention with recordings addresses causation more directly than noting that two populations vary together. Nevertheless, a response does not establish that only one cell type was activated or that the intervening connection is direct. Spatial spread and the stimulated elements remain experimental questions.

Physical detector-response locators: §3.1.4, printed p. 37, defines the volume-averaging correction through the point dose and spatially averaged dose in undisturbed water; equation (5) includes spatial weighting. Appendix I.2.3, printed pp. 145–150, equations (52)–(53), discusses measured lateral profiles, geometric weighting models and averaging corrections. These locators support the detector-response physics.
