2021, Physiology and BehaviorCitation Excerpt :The current latencies align with previous reports that measure latency from periphery to center entry ranging from 10-100s [20, 21, 59]; rodents in the current study showed an average latency of 53s. While previously published data from the FEP is less extensive, the current results are again consistent with earlier work showing rats spend approximately 60-82% of their time in the novel side [18, 19, 55, 56, 67, 68] compared to 81% in the current results. Number of entries into the novel side are highly variable across reports, ranging from 2-3 attempts in some previous work [55] to 0-16 in another [19].

2018, Brain Research BulletinCitation Excerpt :FEP is, to the best of our knowledge, the only test proposed as a model of trait anxiety (Griebel et al., 1993; Teixeira-Silva et al., 2009; Oliveira et al., 2014; Almeida-Souza et al., 2015). This free choice paradigm was first described by Hughes (Hughes, 1965, 1968), who observed that Wistar rats actually preferred the novel environment, spending more time in it. Misslin and collaborators (Misslin et al., 1982; Misslin and Cigrang, 1986) observed that Swiss mice, in this situation, did not present physiological signs of fear unless they were forced into the novel environment, indicating that there was no change in state anxiety during this test situation.
