Abstract

Transcranial direct current stimulation (tDCS) has demonstrated increasing promise as a method of modifying brain activity and cognitive function. The objective of this comprehensive review of the literature is to evaluate the impact of tDCS on explicit and implicit emotion regulation strategies. An extensive review of the literature, conducted using keywords "tDCS," "emotion regulation," "implicit emotion regulation," and "explicit emotion regulation" in Google Scholar, PubMed, Scopus, and Web of Science databases, identified studies meeting the inclusion and exclusion criteria. Twenty studies overall, encompassing both implicit-automatic and explicit-controlled emotion regulation strategies, were found after an extensive review of the literature. There has been a lot of research conducted on explicit emotion regulation, however not as much on implicit emotion regulation. The review revealed that tDCS administration has demonstrated promising effects on enhancing emotion regulation performance across various tasks and neural targets. Nevertheless, inconsistencies in the literature highlight the necessity for further research to elucidate the precise mechanisms underlying tDCS-induced changes in emotion regulation, as well as to explore individual differences in treatment response. In conclusion, this review highlights the potential of tDCS as a valuable intervention for enhancing emotion regulation processes, with implications for both clinical practice and basic research in affective neuroscience.

Duygu Düzenlemesinin Geliştirilmesi: tDCS Etkilerinin İncelenmesi

Abstract

Transkraniyal doğru akım stimülasyonu (tDCS), beyin aktivitesini ve bilişsel fonksiyonu değiştirme yöntemi olarak artan bir umut vaat etmektedir. Bu kapsamlı literatür taramasının amacı, tDCS'nin açık ve örtük duygu düzenleme stratejileri üzerindeki etkisini değerlendirmektir. Google Scholar, PubMed, Scopus ve Web of Science veritabanlarında "tDCS", "duygu düzenleme", "örtük duygu düzenleme" ve "açık duygu düzenleme" anahtar kelimeleri kullanılarak yapılan kapsamlı bir literatür taraması, dahil etme ve dışlama kriterlerini karşılayan çalışmaları belirlemiştir. Kapsamlı bir literatür taramasının ardından, hem örtük-otomatik hem de açık-kontrollü duygu düzenleme stratejilerini içeren toplamda yirmi çalışma bulunmuştur. Açık duygu düzenleme üzerine birçok araştırma yapılmış olmasına karşın, örtük duygu düzenleme üzerine o kadar fazla araştırma yapılmamıştır. İnceleme, tDCS uygulamasının çeşitli görevler ve nöral hedefler üzerinde duygu düzenleme performansını artırmada umut verici etkiler gösterdiğini ortaya koymuştur. Bununla birlikte, literatürdeki tutarsızlıklar, tDCS'nin duygu düzenlemedeki değişikliklere neden olan kesin mekanizmaları açıklığa kavuşturmak ve tedaviye yanıt veren bireysel farklılıkları araştırmak için daha fazla araştırmaya duyulan ihtiyacı vurgulamaktadır. Sonuç olarak, bu inceleme, tDCS'nin duygu düzenleme süreçlerini geliştirmede değerli bir müdahale olarak potansiyelini vurgulamakta olup, hem klinik uygulamalar hem de duygusal sinirbilim alanındaki temel araştırmalar için önemli etkileri bulunmaktadır.
