Importance of Physiology

The PSSL is proud of its track record of having organised the Koch and K.N. (Bull) Seneviratne Memorial Orations on several previous occasions, including the worst of times in our recent history. The PSSL itself is poor, but we are content because we have been rich and rich enough in the intellectual quality of the orations we have offered annually.

Though the role of the discipline of Physiology in the medical curriculum is no longer a major one, the importance of human Physiology, the scientific study of how the body works, remains undiminished. We believe that it is the proper study of humankind.

President's Message

I am honored to be inducted as the President of the Physiological Society of Sri Lanka for the year 2026. In the coming year, I hope to continue the legacy and vision of the brilliant academics and great role models who established this umbrella body 39 years ago, unifying all physiologists in the country, to search, teach, serve, and network. I thank the previous council, led by Professor Dinithi Fernando, for the successes and wisdom (and some challenges) they passed down to me and the present council.

As we have been conducting over the years, the 2026 PSSL calendar comprises two main activities for academics: the Regional Meeting, and the Annual Scientific Sessions. The Regional Meeting (March 2026), will be an academic and social event, that knits geography and generations, as the founders of the PSSL envisioned. The Annual Scientific Sessions with its prestigious orations, symposia and free paper sessions, will be of scientific merit on par with the world. I warmly invite all physiologists, allied scientists and clinicians to submit their research to the PSSL Annual Academic Sessions held in November 2026. This will also be a great opportunity to network with your colleagues in a fostering ambience.

In an era with unprecedented advancement and democratization of knowledge, teachers or textbooks can no longer claim their unquestionable authority on a subject. Physiology is no exception. Read More
