No differences in freezing responses between non-transgenic and transgenic rats were detected during contextual
fear conditioning testing at this early stage (F2, 21 = 1.043; p > 0.05)(Figure 6b).
They then performed serial behavioral tests on the mice, including Y - maze test (to assess working memory), rotarod test (motor function and learning), and contextual and cued
fear condition test (fear learning and memory).

Although not explicitly
tested here, one possibility suggested by the present study is that, in much the same way that stimuli that historically have threatened survival (e.g., snakes, spiders) are considered to be prepared
fear stimuli [stimuli that are more readily
fear conditioned and more difficult to extinguish (39, 40)-RSB- attachment figures may be prepared safety stimuli, that is, stimuli that historically have benefited survival and thus may inhibit
conditioned fear responding.
