Cerebellar stimulation in alumina-gel monkey model: inverse relationship between clinical seizures and EEG interictal bursts

Abstract

The efficacy of cerebellar stimulation was addressed in a chronic monkey model (N = 12) of spontaneous focal motor and secondarily generalized seizures using 24 hr seizure frequency monitoring and all-night EEG recording. The anterior cerebellar vermis was stimulated employing parameters similar to those used in man, 10 Hz, 1 msec pulses, 10 min on, 10 off, at an average current of 2.0 mA. Six weeks pre- and post-base-line periods were compared to a stimulation period of the same length. The results contribute to a clarification of conflicting findings of previous researchers by revealing an inverse relationship between seizure frequency and interictal EEG bursts during the weeks of stimulation. Seizure frequency increased significantly and interictal bursts decreased. Both of these effects (especially the former) were evident in the post-stimulation period, but for different reasons than hypothesized for the period of stimulation. Whereas the therapeutic value of cerebellar stimulation on seizures may be in question, its utilization in the study of mechanisms of epilepsy may be warranted.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

The Tendon Seed Network

Tendons are rich in the extracellular matrix and are abundant throughout the body providing essential roles including structure and mobility. The transcriptome of tendons is being compiled to understand the micro-anatomical functioning of tendons. Discover the latest research pertaining to the Tendon Seed Network here.
