Sex differences in rats' performance on a stationary hidden-platform task spatial task in the Morris water maze and the effects of initial nonstationary hidden platform training NSP training were examined. The NSP training was designed to familiarize rats with the general requirements of the water-maze task without providing spatial information. NSP training led to faster acquisition and improved retention of the subsequent spatial task in both males and females. There was a sex difference favoring males on acquisition and retention of the spatial task only in rats that had not received previous NSP training. Moreover, there was an apparent reversed sex difference favoring females on some measures of spatial performance in NSP-trained rats. These results suggest that performance on the water-maze task, including the expression of sex differences, can be altered by previous familiarization with nonspatial aspects of the task.

The purpose of the present study was to investigate spatial processing performance in male and female CD-1 mice. A substantial literature supports the existence of significant sex differences in both human and rodent models of learning and memory. The nature of these differences is dependent upon the parameters of the task, species and strain of animal. On the final day of radial maze testing, male CD-1 mice committed marginally significantly fewer reference memory RM and significantly fewer working memory WM errors on the radial maze task than female CD-1 mice. In addition, female mice obtained significantly fewer rewards during the final two testing sessions. The present data provide the first evidence for sex differences in radial maze learning in the CD-1 mouse, a strain known for its estrogen insensitivity.

Effects of direct electric fields, noise, sex and age on maze learning in rats

Led by Michael A. This means taking a comprehensive approach — one of compassion, medical sophistication and an openness to new techniques — that extends to each individual area of our practice. Most men like sex. And many, at some point in their lives, want to have children.

Time and error scores of rats running a modified Lashley left-right maze with an escape-from-water motive served as criteria. The results indicate that a adult rats pre-exposed to electric fields showed significantly lower error scores than young rats, regardless of sex or the noise condition; b after exposure to electric fields all rats swam faster than their controls; c after exposure to noise females showed significantly higher time scores than males under the same conditions, regardless of age; and d when subjected to the combined effect of electric fields and noise males showed significantly lower time scores than females under the same conditions, regardless of age.
