Sex differences in conditioned taste aversion and in the effects of exposure to a specific pulsed magnetic field in deer mice Peromyscus maniculatus. med./bio.

Published in: Physiol Behav 2000; 71 (3-4): 237-249

Aim of study (acc. to author)

To investigate the effects of pulsed magnetic field exposure on conditioned taste aversion in male and female deer mice (Peromyscus maniculatus augustus).

Background/further details

In a first experiment general conditioned taste aversion (in the absence of magnetic fileds) was investigated.
In a second experiment the effects of pulsed magnetic field exposure were studied.

Main outcome of study (acc. to author)

Without MF-exposure male and femal mice developed the same intensity in taste aversion, however male mice showing a longer duration of flavor adversion than femals. As a consequence of MF-exposure neither male nor femal mice developed a taste aversion. But a sex difference in response to MF-exposure was observed: male mice exhibited a significantly enhanced novel taste preference. This effect was not observed in femal mice.
