The remarkable efficacy of deep brain stimulation (DBS) for a range of treatment-resistant disorders is still not matched by a comparable understanding of the underlying neural mechanisms. Some progress has been made using translational research with a range of neuroscientific techniques, and here we review the most promising emerging principles. On balance, DBS appears to work by restoring nor...
In the following text, medical, anthropological and ethical issues of deep brain stimulation, a medical technology in which electrodes implanted in the human brain electrically influence specified brain regions, will be discussed. After a brief account of the deep brain stimulation procedure and its chances and risks, anthropological and ethical aspects of the approach will be discussed. These ...
Depleted of dopamine, the dynamics of the parkinsonian brain impact on both 'action' and 'resting' motor behaviour. Deep brain stimulation has become an established means of managing these symptoms, although its mechanisms of action remain unclear. Non-invasive characterizations of induced brain responses, and the effective connectivity underlying them, generally appeals to dynamic causal model...
OBJECTIVE Deep brain stimulation is currently an experimental treatment for major depressive disorder. Information is lacking, however, on how sham responding may affect efficacy. This article applies exploratory meta-analysis to address that topic. METHODS Data on benefits of deep brain electrical stimulation come from a recent review. Stimulated brain regions included subgenual cingulate, c...
OBJECTIVE To quantify postural sway in subjects with Parkinson's disease and elderly controls, and determine the effects of Parkinson's disease, deep brain stimulation, levodopa, and their interactions on postural control during quiet stance. METHODS Centre of foot pressure (CoP) displacement under each foot was measured during three 60 s trials of quiet stance with eyes open in 11 controls a...
