Deep brain stimulation (DBS) has shown remarkable therapeutic benefits for patients with otherwise treatment-resistant movement and affective disorders. This technique is not only clinically useful, but it can also provide new insights into fundamental brain functions through direct manipulation of both local and distributed brain networks in many different species. In particular, DBS can be used in conjunction with non-invasive neuroimaging methods such as magnetoencephalography to map the…

This short review would like to introduce the recent work on the physiological mechanism of DBS and propose an alternative explanation: DBS dissociates input and output signals, resulting in the disruption of abnormal information flow through the stimulation site.

Two approaches to achieve dynamic electric field control during deep brain stimulation are proposed, based on the use of current-steering multipolar electrodes and phased arrays in order to create an electromagnetic beam, which can be steered to a desired location.

The increased blood flow at terminal fields of thalamocortical projections suggests that DBS stimulates and does not inactivate projection neurons in VIM thalamus.

This hypothesis would explain the present experimental results, is consistent with excitability profiles of neuronal elements based on their biophysical properties, and fits with more recent models emphasizing the role of altered patterns of neuronal activity in the development of hypokinetic and hyperkinetic movement disorders.

The present findings suggest that local HF stimulation inhibits many STN neurons, and the overall effects of DBS stimulation in STN are likely to be inhibition of intrinsic and synaptically mediated activity, and its replacement by regular high-frequency firing.

Deep brain stimulation of the subthalamic nucleus does not increase the striatal dopamine concentration in parkinsonian humans

PET data in living parkinsonian humans do not provide evidence for an increased striatal dopamine concentration under effective STN‐DBS, and it is concluded that the modulation of dopaminergic activity does not seem to play a crucial role for the stimulation's mechanisms of action in parkinsonia humans.

The hypothesis of stimulation-induced modulation of pathological network activity as a therapeutic mechanism of DBS is supported after apparently contradictory results showing suppression of activity in the stimulated nucleus, but increased inputs to projection nuclei.
