Research Overview

We study how pain affects cognition and how cognition shapes pain perception. For example, we are interested in understanding how placebo and nocebo effects emerge, how sensory words are learned, how pain perception is modulated by social observation.

Understanding sensory perception can shed light on the neurobiology of complex cognitive processes. Unveiling the relationship between pain and cognition can be relevant for understanding not only chronic pain conditions but also psychiatric and neurological disorders, such as depression and stroke, ultimately informing diagnosis and treatment.

Previous sessions:

Session 1: Pain & Sleep. Hosts: Dr. Natalia Egorova and Prof. Amy Jordan. 07/10/2020. We discussed the relationship between acute pain and sleep. We first talked about a paper on the effect of sleep fragmentation on pain sensitivity, followed by a discussion of possible novel interdisciplinary projects we can undertake at MSPS. 

Session 2: Pain & Music. Hosts: Dr. Natalia Egorova, Dr. Jeanette Tamplin, Prof. Kat McFerran. 04/11/2020. We discussed the relationship between pain and music. We first presented a review paper on how music relieves pain, and then had a general discussion of music effects on experimental, acute, and chronic pain, including efficacy of music therapy.

Session 3: Pain & Reward. Hosts: Dr. Natalia Egorova, A/Prof Stefan Bode. 09/12/2020. We discussed the relationship between pain and reward. We first presented a paper on how humans integrate the prospects of pain and reward during choice, and then had a general discussion of the effects of pain on reward and information seeking.
