Bb5a31f81ClaimNeurobiological research by Dr. Lindsay Schwarz demonstrates that specific midline thalamic circuits regulate behavioral switches between forward engagement, freezing, and retreat in response to predatory threatsAgreeDisagree
Bb5a31f81ClaimHistorian A. Roger Ekirch documented that pre-industrial human sleep was routinely divided into two intervals separated by an awake period called the watchAgreeDisagree
Bb5a31f81ClaimIn historical biphasic sleep, individuals slept for roughly four hours, stayed awake for several hours, and then slept a second phaseAgreeDisagree
Bb5a31f81ClaimThe mammalian hypothalamus contains primitive neural circuits that govern fundamental instinctive drives including mating, feeding, fighting, and fleeingAgreeDisagree
Bb5a31f81ClaimSilencing specific prefrontal cortical neural circuits in mice causes previously dominant mice to lose territory battles in the rodent tube testAgreeDisagree

Bb5a31f81ClaimSubjects placed in pre-industrial lighting conditions naturally revert to biphasic sleep patternsAgreeDisagree
Bb5a31f81ClaimHuman circadian rhythm disruptions and continuous daylight exposure severely impair the production of restorative sleep architecture and neurotransmitters regulating motivationAgreeDisagree
Bb5a31f81ClaimNeurosurgical patients self-stimulating the midline thalamus in Dr. Robert Heath's studies reported feelings of mild frustration and anger that they experienced as highly arousing and motivatingAgreeDisagree
