Whether it is in private or professional lives, people are called to make decisions and they tend to seek expert advice. The old adage indicates that more heads are better than one. Receiving more information is often helpful to decisions. However, getting multiple conflicting expert advice might put decision makers in difficult situations. Little is known about their feelings, thinking, and behaviors under such conditions. This research aims to fill the gap and understand the abovementioned consequences of taking multiple conflicting expert advice when making professional (i.e., business or personnel-related) decisions. Using an interview-based qualitative approach, this research sheds light on contextual characteristics where conflicting expert advice may be more beneficial (or harmful), which contributes practical recommendations to improve professional decisions. In sum, this research seeks to verify whether the common wisdom of “more is better” holds up to empirical scrutiny, and suggests that it is “no pain, no gain”.

Epilepsy, as the most common chronic neurological disease, affects a significant part of population (0.5-1%). Drug resistant epilepsy has a significant negative effect on the quality of life, psychiatric comorbidities, neurocognitive performance and the risk of SUDEP in children. Therefore, resective epilepsy surgery, the only curative treatment of this condition, can fundamentally reverse this unfavorable prognosis. An inevitable prerequisite for a good postoperative result is complete removal of the epileptogenic zone (EC) and preservation of eloquent areas (EC). At present, even with improving and new preoperative non-invasive methods, we don't have an exclusive diagnostic method for theirs delineation. The aim of this PhD study is to assess benefit of individual intraoperative electrophysiological (iEF) methods in pediatric patients with focal intractable epilepsy. The first study evaluates the importance of intraoperative electrocorticography (iECoG) in the localization of EZ. The study proved that iECoG serves as a reliable tool to guide surgical resection and may predict results of epilepsy surgery. iECoG-based modification of surgical plan is not associated with increased risk of significant complications. The second presented study analyzed the contribution of intraoperative electrical...
