EFFECTS OF ORCHIECTOMY ON EXPLORATORY BEHAVIOUR OF RATS

W. D. Ratnasooriya, H. S. Caldera

Abstract


This study was designed to assess whether the testes influence the
exploratory behaviour of rats. The results show that orchiectomy
parameters of exploratory behaviour, namely the number of head dips,
locomotory significantly impaired three activity and number of rears,
when evaluated using the hole-board technique. The fourth parameter
tested, the time spent head dipping however remained unaltered.
These findings suggest that some factor/s secreted by testes influence
exploratory behaviour.

Key words: orchiectomy, exploratory behaviour, rat, hole-board technique.
