Advanced methods for human neuromodulation

NX-436 / 4 credits

Teacher: Hummel Friedhelm Christoph

Language: English

Summary

Neuromodulation is an expending field especially in human translational neuroscience and neurotechnology. This course will introduce to different approaches / technologies for neuromodulation, their underlying mechanisms of action and application in humans in healthy and pathological conditions.

Content

The students will be introduced to different (invasive and non-invasive) approaches and technologies for neuromodulation, to their underlying mechanisms of action and to their application in humans in healthy and in pathological conditions such as Stroke, Parkinson's, Dementia, Traumatic Brain Injury or Depression. The course will address and elaborate together with the students on neuromodulation approaches based on e.g., electrical (invasive, non-invasive), magnetic stimulation, focussed ultrasound as well as pharmacological or opto/sonogenetic modulation. Furthermore, aspects like state-dependent, closed-loop approaches or technologies for home-based self-application, as well as safety, cost-effectivity and ethics will be addressed, and important regulatory, neuroethical and R&D aspects.

The course content is organized as follows. Each week 2 x 45 min lectures and 2 x 45 min exercise.
