TL;DR

A diurnal oscillation of acetylcholine concentrations in rat brain has been demonstrated by gas chromatography and emerges after at least 18 days of prior conditioning in an environment with controlled light, humidity, and temperature.

Abstract

A diurnal oscillation of acetylcholine concentrations in rat brain has been demonstrated by gas chromatography. Peak concentrations occur at 2 hours of light, and a trough is seen at 6 hours of darkness. This pattern is observed only in grouped rats, and emerges after at least 18 days of prior conditioning in an environment with controlled light, humidity, and temperature.
