Methods: A questionnaire was used to measure college students’ self-efficacy and explicit altruistic behaviors, and the Go/no-go association test was used to measure implicit altruistic behaviors. Results: 1) There was no significant difference in implicit altruism between male and female college students, nor was there a significant difference in whether they were only children or not;2) implicit altruism and externally expressed altruism were separated;3) self-efficacy was significantly correlated with implicit altruism;4) self-efficacy was insignificantly correlated with externally expressed altruism, but was significantly and positively correlated with the factor of respecting and caring for others. Conclusion: The Go/no-go association test is a valid measure of implicit altruism.展开更多

Recent studies have shown that the necklace olfactory system in mice sensitively detects CO2 in the air. Olfactory CO2 neurons are believed to rely on cyclic gnanosine monophosphate （cGMP） as the key second messenger; however, the specific ion channel underlying CO2 responses remains unclear. Here we show that CO2-evoked neuronal and behavioral responses require cyclic nucleotide-gated （CNG） channels consisting of the CNGA3 subunit. Through Ca2＋-imaging, we found that CO2-triggered Ca2＋ influx was abolished in necklace olfactory sensory neurons （OSNs） of CNGA3-knockout mice. Olfactory detection tests using a Go/No-go paradigm showed that these knockout mice failed to detect 0.5% CO2. Thus, sensitive detection of atmospheric CO2 depends on the function of CNG channels consisting of the CNGA3 subunit in necklace OSNs. These data support the important role of the necklace olfactory system in CO2 sensing and extend our understanding of the signal transduction pathway mediating CO2 detection in mammals [Current Zoology 56 （6）： 793-799, 2010].展开更多
