Readiness potential

In science, readiness potential refers to a scalp recorded slow negative electroencephalography (EEG) potential shift that begins up to a second or more before a self-paced act. [1]

The concept of readiness potential, or "bereitschaftspotential" in the original German, first recorded and reported in 1964 by German researhers Hans Kornhuber and Luder Deecke at the University of Freiburg, Germany. [2]

In hmolscience, the topic of readiness potential frequently arises, particularly in discussions of the how's and why's of human movement, when people are modeled specifically abstract molecules or "human molecules", specifically. An example is the following comment made by American electrochemical engineer Libb Thims during the 2009 Moriarty-Thims debate:

“How this is applied to people moving, using a very simplistic model, is outlined here. In this calculation, to note, you get into issues of free will, readiness potential, and induced movement. This issue of “what if a student chooses to move this way” is confusing for many people. Molecules do not *decide* or choose to move, neither do human molecules. Regarding speed distributions and system temperature, this is a huge issue. The issue revolves around the question of how one connect concepts such as sexual temperature (physical beauty) or economic temperature, and so on, with absolute temperature. This issue is still very puzzling. An example is the measured correlation that, determined by psychologists, that physically attractive people (e.g. supermodels) will cause a volume expansion (given more personal space) when moving through a crowd of people, as compared to more homely looking individuals (personal space).”

on the question of whether or not the movements of students in a field will follow a Maxwell-Boltzmann distribution and have a measurable entropy.
