• In the EPM, female rats showed lower anxiety-like behavior than males, whereas CHF rats were more anxious than CLF rats. (bvsalud.org)
  • In this context, a higher faecal excretion and lower tissue accumulation, as well as metallothionein induction in rats following exposure to methylmercury naturally incorporated in fish compared to methylmercury chloride added to the same matrix, have been reported [ 3 ]. (hindawi.com)
  • Such differences in emotionality responses in the 10th generation of selected rats further indicate a possible use of this model to study correlations between trait anxiety and defen- sive reactions. (bvsalud.org)
  • This work extended his mentor Tryon's earlier rat demonstration that they could be bred to do well or poorly in learning a maze. (wikipedia.org)
  • The SHR and SLA16 inbred strains present behavioral differences in anxiety/emotionality that could be under the influence of dopaminergic neurotransmission. (bvsalud.org)
  • The present study further analyzed behavioral correlates of two novel breeding lines of rats, Carioca high-and low-conditioned freezing (CHF and CLF), based on defensive freezing responses to contextual cues previously associated with electric footshock. (bvsalud.org)
