transfer arousal and body tone

[TallKing]

Description of effects of a pharmacological agent on behaviour and motoric activity of male rats:

"Less frequently observed signs were decreased locomotor activity, transfer arousal and body tone, prone posture, apathy, impaired wire maneuver, twitches, head tilt, noisy respiration, and red colored urine".

What is transfer arousal and body tone here?

Many thanks in advance
