The present study examined whether serotonin (5-hydroxytryptamine; 5-HT)7 receptors play a role in the modulation of emotionality in mice using the selective 5-HT7 receptor antagonist 2a-[4-(4-phenyl-1,2,3,6-tetrahydropyridyl)butyl]-2a,3,4,5-tetrahydrobenzo (c,d)indol-2-(1H)-one (DR4004). The emotionality of mice was evaluated in terms of exploratory activity in

Fear conditioning is a valuable behavioral paradigm for studying the neural basis of emotional learning and memory. The present study examined the involvement of extracellular signal-regulated kinase 1/2 (ERK) signaling on the serotonin (5-HT)
Kazumasa Horikawa et al.
Journal of pharmacological sciences, 123(4), 402-406 (2013-12-03)
Several lines of evidence indicate that serotonin type 7 (5-HT7) receptors play a critical role for non-photic resetting of the mammalian circadian clock; however, the contributions of other types of 5-HT receptors to non-photic entrainment are not yet clarified. The
