Project description:

Title:
Neural circuits mediating analgesia
Summary:
Chronic pain is a major health problem word-wide. Our laboratory works on elucidating mechanisms and circuits underlying chronic pain (see, for example, Tan et al. Nature Communications 2019; Tan et al. Nature Neuroscience 2017; Vicuna et al. Nature Medicine 2015; Kuner and Flor, Nature Reviews Neuroscience 2016). We are seeking PhD students in projects aimed at elucidating brain pathways and mechanisms involved in chronic pain in mouse models. Methods include viral-based circuit mapping, labelling cellular engrams, optogenetics, chemogenetics, in vivo multiphoton imaging, in vivo electrophysiology, neuromodulation and behavior.

This project involves in vivo recordings of brain oscillatory activity in awake behaving mice and addressing their relevance to pain chronicity.
A related goal is to address circuits mediating analgesia induced by brain stimulation approaches, such as transcranial magnetic stimulation, using transgenic mice and the above-described methods.
The approaches will enable deep insights into activity patterns and circuits mediating chronic pain and applying this knowledge to improve brain stimulation paradigms in pain therapy.
