Neuronal correlates of hippocampal activity at phasic and sustained fear in fear conditioned mice.
Regions of the ventral and dorsal hippocampus differentially contribute to processes of learning and memory. While animals with dorsal hippocampal lesions show deteriorations in cognitive functions like e.g. spatial memory (Morris et al., 1982; O’Keefe and Nadel, 1978; Gaskin and White, 2006), lesions in ventral hippocampus impair animals fear behavior in respective behavioral paradigms (e.g. “open-field”, “elevated-plus-maze”; Hock and Bunsey, 1998; McHugh et al., 2004; Kjelstrup et al., 2002; Pentowski et al., 2006). So far, distinct contributions of both brain regions to the processes of conditioned fear have not been investigated. Thus, the aim of this study is to investigate the neuronal correlates of hippocampal activity (field potential-, single cell recordings) in phasic and sustained fear after fear conditioning in mice.
