Minimally invasive endoscopes for neuronal activity monImaging-assisted single-cell specific activity monitoring and optogenetic stimulation of deep brain structures in motile and awaken animal models

Introduction

Severe neuronal disorders such as dementia affect more than 1 billion people globally and account for an economic burden far exceeding that of cancer. Our only chance of treating dementia is improving our understanding of how brains function at diverse levels of complexity. This will only be possible through better technologies, which already reflects in synchronized actions worldwide, such as the US Brain Initiative and EU Human Brain Project.

Project Background

The origin ERC project LIFEGATE has developed minimally invasive (hair-thin) endoscopes for advanced applications in neuroscience and brought about a solid route to their commercial outreach. The instruments rely on state-of-the-art digital holographic methods combined with high-performance computing. They offer uniquely detailed observations in unprecedented depths of living, yet anesthetized, animal models, making them particularly suitable for studies of connectivity of neuronal cells inside their natural environment.

Proposal Overview

This proposal, entitled WOKEGATE, represents a powerful extension of this concept, enabling imaging-informed, single-cell specific activity monitoring and control of deep neuronal circuits in fully awake and behaving animals. The prospect is centered around a novel M3CF fibre probe which emerged within the origin ERC project LIFEGATE, outside its proposed research agenda.

Project Objectives

The project aims for:

1. Necessary technological amendments to incorporate this opportunity into the holographic endoscope geometries.
2. A direct verification of this prospect in in-vivo studies through the network of existing research partners.
3. Paving the way for commercial translation of such empowered scientific instrumentation.

Future Perspectives

Successful acquisition and execution of the WOKEGATE will enable future perspectives of this promising technology through new opportunities such as the EIC Accelerator grant.
