Study Abroad Program

The followings are the students' reports on overseas activities including poster sessions, oral sessions, or heated discussions at the international meetings. These precious experiences will provide great benefit for their studies, as well as minds.

Report on attendance at Neuroscience 2013 and visit to University of California

I visited San Diego to attend Neuroscience2013 which is one of the largest scientific meeting in neuroscience. It was held at The San Diego Convention Center in November 9 - 13. After Neuroscience2013, I went to Irvine and visited Professor Sumikawa's laboratory (Department of Neurobiology and Behavior) in University of California. I looked around his lab and attended lab seminar. This was my first attendance at international meeting and visit overseas laboratory. So I also felt it difficult to communicate with other researchers and local people. But I was able to have a good experience for linguistic and scientific studies. Below, I will write some of these experiences.

In November 12, I had a poster presentation titled "Asymmetric dendritic spine dynamics in the apparently symmetric long-lasting synaptic plasticity phenomena after repeated LTP/LTD inductions". My main theme is to research the spine dynamics after repeated LTD inductions. In this poster, I focused on the difference between the repeated LTD and repeated LTP which is reported by my superior researcher. This was my first presentation in English. So sometimes it was a little difficult for me to explain results and tell my ideas. But overseas researchers were very friendly, so they tried to understand my opinions. Many people came to my poster and I could get many good advises. From many questions and opinions, I could get another angle about my research. Poster session was a short time, but it raised my motivation for research.

Not only own presentation, I went many posters and got information about spine dynamics. Most interested poster was "Mechanisms of activity-dependent shrinkage of dendritic spines" because I have read article written by its presenter. Similar to our research, they focused on spine morphological change after LTD induction. Their results gave me idea of another consideration. I consulted their article in my experiment, so I was very glad to discuss.

In November 14, I went to Irvine to visit Department of Neurobiology and Behavior in University of California Irvine. Main purpose of this visit was to observe laboratory and attend lab seminar. This laboratory researches the function of nicotinic acetylcholine receptors (nAChRs). Their objective is different from our laboratory but experimental methods are related to our study. So I observed various experiments like path clamp recording, voltage sensitive dye recording and hippocampal acute slice preparation. After that, I attended lab seminar and had presentation of my research. There was difficulty that is different from poster presentation in the oral presentation. I could not attend the speed of talk and line of slight which I usually attend in Japanese presentation. So I felt that more practice for English presentation is needed.

In this trip, I could experience both oral and poster presentation. But there were many scenes that I could not communicate with other people because my English skill was not good. So I want to improve my English skill enough to mention own ideas and ask my questions for next. At the end, I am deeply grateful to Professor Sumikawa, everyone involved, and this program.
