Tailoring transcranial alternating current stimulation based on endogenous even...
Mendes, Augusto, J.; Calvo, Alberto Lema; Carvalho, Sandra; Leite, JorgeBackground. Transcranial alternating current stimulation (tACS) is a brain stimulation method for modulating ongoing endogenous oscillatory activity at specified frequency during sensory and cognitive processes. Given the overlap between event-related potentials (ERPs) and event-related oscillations (EROs), ERPs can be studied as putative biomarkers of the effects of tACS in the brain during cognitive/sensory t...
Transcranial direct current stimulation decreases P3 amplitude and inherent del...
Mendes, Augusto José; Galdo-Álvarez, Santiago; Calvo, Alberto Lema; Carvalho, Sandra; Leite, JorgeThe inability to wait for a target before initiating an action (i.e., waiting impulsivity) is one of the main features of addictive behaviors. Current interventions for addiction, such as transcranial Direct Current Stimulation (tDCS), have been suggested to improve this inability. Nonetheless, the effects of tDCS on waiting impulsivity and underlying electrophysiological (EEG) markers are still not clear. Ther...
Transcranial Random Noise Stimulation (tRNS) on Attention Network Test (ANT): a...
Calvo, Alberto LemaSpeed-accuracy tradeoff (SAT) refers to the adjustment between response speed and its accuracy, a process mediated through cortical and subcortical circuits. However, it remains unclear whether SAT can be modulated by the effects of tRNS and/or tDCS. In order to explore this effect, we used the attention network test (ANT). This tasks allowed us to test three independent networks related to both subcortical act...

Coutinho, Joana Fernandes Pereira; Beiramar, Ana Sofia Pinto Vieira; Silva, Carla; Calvo, Alberto Lema; Lima, Vânia; Grace, RandolphThe main objective of this study was to translate and adapt the Interpersonal Reactivity Index for Couples (IRIC) to Portuguese, and analyze the psychometric properties of the Portuguese version. This instrument that assesses empathy in couples, resulted from the adaptation of one of the most widely used empathy scales - Davis's Interpersonal Reactivity Index - for the context of intimate relationships. The IRI...
