RESUMO
The Enteric Nervous System (ENS) is described as a division of the Peripheral Nervous System (PNS), located within the gut wall and it is formed by two main plexuses: the myenteric plexus (Auerbach's) and the submucosal plexus (Meissner's). The contribution of the ENS to the pathophysiology of various neurological diseases such as Parkinson's or Alzheimer's disease has been described in the literature, while some other studies have found a connection between epilepsy and the gastrointestinal tract. The above could be explained by cholinergic neurons and neurotransmission systems in the myenteric and submucosal plexuses, regulating the vagal excitability effect. It is also understandable, as the discharges arising in the amygdala are transmitted to the intestine through projections the dorsal motor nucleus of the vagus, giving rise to efferent fibers that stimulate the gastrointestinal tract and consequently the symptoms at this level. Therefore, this review's main objective is to argue in favor of the existing relationship of the ENS with the Central Nervous System (CNS) as a facilitator of epileptogenic or ictogenic mechanisms. The gut microbiota also participates in this interaction; however, it depends on many individual factors of each human being. The link between the ENS and the CNS is a poorly studied epileptogenic site with a big impact on one of the most prevalent neurological conditions such as epilepsy.
RESUMO
BACKGROUND: Bibliometric analysis allows us to quantify and evaluate scientific activity, and it has become increasingly important in all areas of scientific literature. Thanks to these analyses, we can infer where science should put greater efforts into elucidating the underlying mechanisms of diseases that have yet to be fully described or investigated. OBJECTIVE: This paper delves into published articles related to the involvement of calcium (Ca2+) channels in epilepsy, which is a condition with a high prevalence in Latin America. METHODS: We followed the scientific publication on SCOPUS and analyzed the impact of publications from Latin America in the field of epilepsy and the study of Ca2+ channels. We identified the countries with the largest number of publications and found that 68% of them were experimental (animal models), while 32% were clinical. We also identified the main journals, growth over time, and citation numbers. RESULTS: We found a total of 226 works produced by Latin American countries from 1976 to 2022. The countries that have contributed the most to the topic are Brazil, Mexico, and Argentina, with occasional collaborations between them to make contributions to the study of epilepsy and Ca2+ channels. Additionally, we found that the journal with the most citations is Nature Genetics. CONCLUSION: The number of authors per article ranges from 1 to 242, and neuroscience journals are the preferred target for researchers, with a predilection for publishing original articles, although 26% of the publications are review articles.
