In vivo models	Frequency (THz)	Intensity, (mW/cm2)	Exposure time	Behavioral effects	Reference
HUMAN human subjects	0.02–8 THz	2.4 mW/cm2	22.5 min	Improve the symptoms of neurological defects	(Reukov et al., 2016)
RAT male albino rats	0.15 THz	0.2 mW/cm2	30 min	Improve behavioral abnormalities	(Kirichuk et al., 2014)
Male albino rats	0.15 THz	3 mW/cm2	60 min	Induce signs of depression.	(Kirichuk et al., 2009)
Male rats	0.167 THz	n.s	5 days	Maintain normal ability to explore new things	(Kirichuk and Ivanov, 2013)
Male rats	0.144 THz	n.s	5 days	Increase anxious and aggressive behavior, reduce appetite and sleep time	(Kirichuk and Ivanov, 2013)
