Cortical hemodynamics of electrographic status epilepticus in the critically ill.
Epilepsia

Department of Neurosciences, Université de Montréal, Montréal, Québec, Canada.
Objectives: The pathophysiological mechanisms of status epilepticus (SE) underlying potential brain injury remain largely unclear. This study aims to employ functional near-infrared spectroscopy (fNIRS) combined with video-electroencephalography (vEEG) to monitor brain hemodynamics continuously and non-invasively in critically ill adult patients experiencing electrographic SE. Our primary focus is to investigate neurovascular coupling and cerebrovascular changes associated with seizures, particularly during recurring and/or prolonged episodes.

Despite the long history of the horse-human bond, our understanding of the brain and mind of horses remains limited due to the lack of methods to investigate their brain functions. This study introduces a novel methodology for completely non-invasive, multi-channel recording of electroencephalography (EEG) and evoked potentials in awake horses to examine equine auditory cortical processing. The new approach utilizes specially designed brush-shaped active electrodes that facilitate stable signal acquisition through the hair coat by penetrating electrode pins and integrated pre-amplifiers.

Transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique, has been shown to increase exercise performance in strength and cycling studies but its effects on running endurance remain unclear. The objectives of this randomized sham-controlled crossover trial were to assess tDCS efficacy on submaximal treadmill running time to exhaustion (TTE). Forty-five healthy male runners aged between 18 and 32 years (mean maximal oxygen consumption: 46.

Ultraflexible neural electrodes have shown superior stability compared with rigid electrodes in long-term recordings, owing to their low mechanical mismatch with brain tissue. It is desirable to detect neurotransmitters as well as electrophysiological signals for months in brain science. This work proposes a stable electronic interface that can simultaneously detect neural electrical activity and dopamine concentration deep in the brain.

Objective: Electric-field orientation is crucial for optimizing neuronal excitation in transcranial magnetic stimulation (TMS). Yet, the stimulus orientation effects on short-interval intracortical inhibition (SICI) and intracortical facilitation (ICF) are poorly understood due to technical challenges in manipulating the TMS-induced stimulus orientation within milliseconds. We aimed to assess the orientation sensitivity of SICI and ICF paradigms and identify optimal orientations for motor evoked potential (MEP) facilitation and suppression.
