This allowed us to examine sex differences in memory retrieval, without the confounding effects of sex differences in acquisition. We looked at two retention time points, 1d or 30d after completing training, to examine how sex differences impact long-term retrieval. Future experiments will examine the levels of PKMζ with and without retention testing to delineate these effects. These females (60 trial / 30d test) also performed significantly worse than their male counterparts for both percent correct and reference errors (Figure 2A-B). Males given 60 training trials did not perform differently when tested 1d or 30d after training.
The specimens can drip flaming particles that ignite the dry absorbent surgical cotton located 300 mm below the test specimen. Furthermore, we employed a protocol whereby the orientation of the rats upon release is randomized between trials but the experimenter remained in the same location when animals were released.

Interestingly, only male cohorts appeared to positively correlate synaptic PKMζ expression with memory retention. Studies in South Africa and in Guatemala show that training was provided for the men, while the women were the main users of the system. Behav Brain Res 208: 408-414. doi:10.1016/j.bbr.2009.12.019.
