Study of regenerative and ontogenetic processes under the influence of EHF EMR.
The increased sensitivity of aquatic organisms to the effects of EMF has been proven by numerous experimental studies. It has been repeatedly noted that exposure to EMF of certain frequencies and intensities leads to disruption of physiological functions, orientation in time and space, changes in the behavior of organisms, suppression of motor activity. Other ranges of electromagnetic radiation, on the contrary, can cause the effects of increased regeneration, growth rate and survival. In connection with these trends, the purpose of our research is to analyze the effects of the influence of electromagnetic radiation of extremely high frequency on the development of the Xenopus laevis and the regeneration of newts and planarians
果蠅(Drosophila melanogaster)的習得性無助表現之研究
習得性無助是個體經多次追求獎賞或逃離困境失敗後產生的一種消極行為表現。習得性無助的行為研究雖多,但對其神經機制的研究卻甚少。 本研究發現273,cha-Gal80>CsC-mCh是適合光遺傳學訓練的果蠅殖系。在白光點獎賞記憶訓練中,使273,cha-Gal80>CsC-mCh果蠅學會白光點視覺訊號代表著獎賞,並發現其白光獎賞記憶能持續7分鐘以上但未達10分鐘。藉已建立白光視覺訊號與獎賞連結的273,cha-Gal80>CsC-mCh,發現重複追求獎賞失敗的實驗組,相較於持續接受獎賞與完成獎賞記憶訓練而無任何操作的對照組,明顯表現習得性無助,本研究亦發現習得性無助個體也表現了活動力、覓食表現及攝食動機的下降。 本研究成功建立高成效的果蠅成蟲光遺傳學習得性無助訓練,並針對果蠅成蟲的習得性無助行為表現進行完整的研究,未來期望本於此訓練方式進行特定腦區、神經群和神經傳遞物之探究,建構果蠅習得性無助的神經網路機制。
