We explored the impact of pulse durations <60 μsec on the therapeutic window of subthalamic neurostimulation in Parkinson's disease. Current thresholds for full rigidity control and first muscle contractions were evaluated at pulse durations between 20 and 120 μsec during a monopolar review session in four patients. The average therapeutic window was 2.16(More)
We propose an improved quantitative measure of EEG during brain injury and recovery after cardiac arrest. In our previous studies, we proposed a measure, information quantity (IQ), to detect the early effects of temperature manipulation on the EEG signals recorded from the scalp. IQ incorporates the wavelet transform and the Shannon entropy in full bands(More)
OBJECTIVE Deep brain stimulation of the subthalamic nucleus (STN-DBS) is an established treatment for Parkinson's disease (PD). Anatomical connectivity analyses and task-related physiological studies have divided the STN into different functional domains: sensorimotor, limbic, and associative - located in its dorsolateral (dSTN), anteroventral (vSTN) and(More)
Background In experimental models of neuronal damage, therapeutic hypothermia proved to be a powerful neuroprotective method. In clinical studies of traumatic brain injury (TBI), this very distinct effect was not reproducible. Several meta-analyses draw different conclusions about whether therapeutic hypothermia can improve outcome after TBI. Adverse side(More)
T he richness of the biological world is a testament to the diversity of life, the conditions under which it can endure, and the remarkable array of robust solutions to environmental challenges. Animals have, over millions of years, evolved complex computations to parse the richness of their natural sensory milieu, as well as mechanisms to transcribe this(More)
BACKGROUND Close relatives (CR) of patients with severe traumatic brain injury (TBI) and high-grade subarachnoid hemorrhage (SAH) suffer extraordinary distress during the treatment: Distress may lead to persisting mental illness symptoms within the spectrum of post-traumatic stress disorder (PTSD), anxiety disorders, and depression. The primary goal of this(More)
