The earliest systematic studies on sleep were conducted by Michel Jouvet. Which of the following statements describe(s) his research?

Small injections of neurotransmitters were used to test hypotheses about trigger mechanisms.;
Large lesions of the brain or transections along the brainstem and subcortical area were made to gain a fundamental understanding of sleep mechanisms.;
The effects of very small lesions to selective areas of the brain were studied to gain a fundamental understanding of sleep mechanisms.;
Small injections of anatomical tracers were made to identify the connections between important sleep controlling areas of the brain.;
All of the alternatives were used by Jouvet in his early studies of sleep.;

INCORRECT - This is a recent experimental technique used to refine our understanding of sleep mechanisms.
