Description

This lecture provides a comprehensive overview of non-invasive brain stimulation (NIBS) techniques, focusing on their historical development and clinical applications. It begins with a historical perspective, tracing the origins of brain stimulation methods back to ancient practices, including early electrical treatments for headaches. The instructor discusses significant advancements in the field, particularly the introduction of transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), highlighting their mechanisms and effects on cortical excitability and neuroplasticity. The lecture emphasizes the importance of NIBS in neurorehabilitation, particularly for stroke recovery, and presents evidence from studies demonstrating its efficacy in enhancing motor function and cognitive abilities. The instructor also addresses the challenges of personalization in treatment protocols, advocating for tailored approaches based on individual patient profiles. Finally, the lecture explores future directions for NIBS, including the potential for home-based applications and the integration of advanced technologies to improve treatment outcomes.

Grégoire Courtine

Grégoire Courtine was originally trained in Mathematics and Physics, but received his PhD degree in Experimental Medicine from the University of Pavia, Italy, and the INSERM Plasticity and Motricity, in France, in 2003. From 2004-2007, he held a Post-doctoral Fellow position at the Brain Research Institute, University of California at Los Angeles (UCLA) under the supervision of Dr. Reggie Edgerton, and was a research associate for the Christopher and Dana Reeve Foundation (CDRF). In 2008, he became Assistant Professor at the faculty of Medicine of the University of Zurich where he established his own research laboratory.

Deep brain stimulation

Deep brain stimulation (DBS) is a neurosurgical procedure involving the placement of a medical device called a neurostimulator, which sends electrical impulses, through implanted electrodes, to specific targets in the brain (the brain nucleus) for the treatment of movement disorders, including Parkinson's disease, essential tremor, dystonia, and other conditions such as obsessive-compulsive disorder (OCD) and epilepsy. While its underlying principles and mechanisms are not fully understood, DBS directly changes brain activity in a controlled manner.

Transcranial direct-current stimulation

Transcranial direct current stimulation (tDCS) is a form of neuromodulation that uses constant, low direct current delivered via electrodes on the head. It was originally developed to help patients with brain injuries or neuropsychiatric conditions such as major depressive disorder. It can be contrasted with cranial electrotherapy stimulation, which generally uses alternating current the same way, as well as transcranial magnetic stimulation. Research shows increasing evidence for tDCS as a treatment for depression.

Neuromodulation (medicine)

Neuromodulation is "the alteration of nerve activity through targeted delivery of a stimulus, such as electrical stimulation or chemical agents, to specific neurological sites in the body". It is carried out to normalize – or modulate – nervous tissue function. Neuromodulation is an evolving therapy that can involve a range of electromagnetic stimuli such as a magnetic field (rTMS), an electric current, or a drug instilled directly in the subdural space (intrathecal drug delivery).

Transcranial magnetic stimulation

Transcranial magnetic stimulation (TMS) is a noninvasive form of brain stimulation in which a changing magnetic field is used to induce an electric current at a specific area of the brain through electromagnetic induction. An electric pulse generator, or stimulator, is connected to a magnetic coil connected to the scalp. The stimulator generates a changing electric current within the coil which creates a varying magnetic field, inducing a current within a region in the brain itself.

Neurostimulation

Neurostimulation is the purposeful modulation of the nervous system's activity using invasive (e.g. microelectrodes) or non-invasive means (e.g. transcranial magnetic stimulation or transcranial electric stimulation, tES, such as tDCS or transcranial alternating current stimulation, tACS). Neurostimulation usually refers to the electromagnetic approaches to neuromodulation.
