The International Organization of Psychophysiology (IOP) and the University of Electronic Science and Technology of China (UESTC) are pleased to invite you to attend the 20th World Congress of Psychophysiology (or IOP 2021) that will be held from September 7 to 11, 2021.

After the brilliant and scientifically prolific 2018 edition in Lucca, Italy, the IOP treks thousands of kilometers and arrives in China for the first time. Due to the pandemic situation, IOP2021 has to be a virtual congress. However, the organizing committee is still from Chengdu, China.

Given its long tradition in neuroscience and psychophysiology, China is well qualified to host and strongly supports IOP objectives, disseminates psychophysiological research worldwide, and promotes international cooperation. Predictably, the memorable 20th meeting organized by Chengdu will bring together scientists from all over the world to discuss the future of psychophysiology.

In order to achieve a sustained interaction between basic and applied psychophysiology, IOP 2021 will cover different hot topics and the latest methodological advances in psychophysiology.

Chengdu is a historically and culturally renowned capital that dates back more than 2,300 years. This city is the hometown of giant panda with many historical sites, such as Dujiangyan, Wuhou Temple, Du Fu Thatched Cottage, Jinsha Site Museum and so on. 

As usual, members of IOP and of affiliated national societies will receive a considerable discount off the registration fees. The researchers who will attend the meeting and are not yet members to join the organization and participate in its future growth are also welcome, please visit the official website of IOP at or the official website of IOP 2021 at

On behalf of the IOP, the whole local organizing committee is honored to welcome you to the 20th World Congress of Psychophysiology. Chengdu will play a very important role in the development of brain science. We look forward to your participation and involvement.
