Why the humble poster session is here to stay. We hear from two poster presenters at FENS.

The scientific poster session has been around since at least the 1970s. One science historian places its origins in meetings of biochemists and physicists back in the late sixties.

Today, poster sessions – scheduled en masse in cavernous exhibit halls – are frequently where the real action happens at scientific conferences. Unlike symposia, where lab PIs formally represent work done by the team, posters are where research methods and findings are explained and defended by first authors; those who did the heaviest lifting back at the lab. Here we offer two first-person experiences by poster session presenters at the recent FENS Forum of Neuroscience.

The Up Side of “Negative” Feedback

Chiara Varazzani, PhD Candidate, ICM – Institut du Cerveau et de la Moelle épinière, Paris France

The recent FENS Forum taught me as much about others’ research as it did about my own. Taking part in the outstanding symposia allowed me to learn from scientists who are currently defining my field and the opportunity to present a scientific poster revealed new insights into my research project.

We are currently working on the respective roles of dopamine and noradrenaline in motivational processes by recording the electrical activity of monkeys’ neurons in two key structures of the brain, namely the Subtantia Nigra and the Locus Coeruleus.

Sharing my results at the FENS forum made me realize the benefits (and limitations) of using classical model-based statistical tools, and helped me get more familiar with the process of taking my ideas through to publication.

In particular, several colleagues did not see eye to eye on the conclusions I drew from my results, challenging the delicate flow from hypothesis to deduction. I presented this work at four international meetings over my first two Ph.D. years and positive feedback has been important at the very beginning by increasing my confidence and my commitment to my work.

However, we are now close to completing this research project and “negative” feedbacks are certainly the most informative and stimulating remarks in this phase. I find that the criticisms I received during my poster presentation just give me the information I need to take my performance to the next level by pointing out where I need to spend my effort.

The “Heart of Science”

Steffen Wolff, PhD, Postdoctoral Fellow, Ölveczky Lab Harvard University, Cambridge, MA

After Geneva and Barcelona, Milano was my third FENS. FENS is a must for me – for the science, but also for so much more. I came to Milano just two weeks after starting my postdoc with Bence Ölveczky at Harvard University, working on motor learning. This might seem early, but for me keeping in touch with European neuroscience is essential, and it was a great opportunity for a first glimpse into motor learning and to meet people in the field. But to get most out of FENS, I really wanted to present my own research.

Obviously, I had no results from my postdoc, yet. Therefore, I presented my PhD work with Andreas Lüthi in Basel, Switzerland, on the role of distinct types of amygdala interneurons in fear learning. I was unsure what to expect since my work had been recently published in Nature. But I got an amazing reception.

While fixing the last piece of sticky tape, I was already asked for a tour! An unbroken stream of visitors followed – sometimes one at a time, sometimes groups in three rows. People with specific questions to the paper mixed with others who were just curious. These different angles and diverse questions triggered stimulating discussions.

Talks or papers are great to share your research, but presenting a poster is a much more direct interaction. No matter if it’s one person or a crowd, you explain, they ask, you see their faces – agreeing, interested, nodding, critical or puzzled – and you react. You repeat, stress a point or engage into a discussion. Presenting a poster is also rewarding – you may get a hint, a piece of advice or ideas – or you realize flaws and missing pieces.

Finally – discussing your results with other scientists is at the very heart of science – science depends on interactions and exchange of ideas In the end, the new thoughts and criticisms you get [presenting a poster session] will help you with refining your project and eventually writing and publishing a paper.

It is absolutely crucial that your paper submission is not the first time other scientists think about your project!
