Objective: To investigate the properties of afterdischarges (ADs) from intracerebral electrical stimulation (ES) in patients with epilepsy who underwent stereotactic electroencephalography (SEEG) and determine the relationship between epileptogenic zone (EZ) or irritative zone (IZ) and ADs.
Methods: We retrospectively analyzed 10 patients with intractable epilepsy who underwent SEEG. ESs were delivered following the given parameters: bipolar, biphasic, 50Hz, 0.
Article Synopsis
- Brief-pulse stimulation at frequencies of 5, 50, and 100 Hz was tested to see how effectively it can stop afterdischarges caused by cortical electrical stimulation in patients with refractory epilepsy.
- The study found that brief-pulse stimulation effectively terminates these afterdischarges, especially when they are localized and haven't spread to nearby brain areas.
- Additionally, a higher frequency (100 Hz) and lower current intensity of brief-pulse stimulation were associated with better chances of successfully terminating the afterdischarges.
: To assess the age-related morphometric changes of subcortical structures in healthy people. : Ultra-high field 7 tesla magnetic resonance (MR) imaging in humans was used to visualize the subcortical structures of healthy young, middle-aged and elderly participants. Using the magnetization-prepared two rapid acquisition gradient echo (MP2RAGE) sequence, we assessed the visibility of the margins of the thalamus and white matter in the thalamus, as well as the anterior commissure (AC) and posterior commissure (PC) length, the maximal height of the thalamus, the half width of the third ventricle and the distance between the AC and the center of the mammillothalamic tract (MTT) at the level of the AC-PC plane.

Method: All 15 patients who underwent perirolandic cortical resection between October 2006 and September 2007 at the Comprehensive Epilepsy Centre of Beijing Xuanwu Hospital were included in the study. The locations of functional cortical areas, ictal onset zones and epileptogenic lesions were mapped by chronic intracranial EEG recordings and electric cortical stimulation.
