“…This is in good agreement with results reported by other authors on the links between β-γ activity mainly with the experience of positive emotions and achievement of high registers of different facets of positive affect in the state of altered consciousness in meditation practices [1,7,10,17,32]. Furthermore, the fi rst successful attempts to use the dynamics of EEG γ power in online classifi ers to detect evoked positive emotions [25] and in biological feedback protocols to induce them [36] have been published.…”

“…The increased activity in the β-γ ranges demonstrated here refl ects, along with the operation of the mechanisms of the cognitive regulation of positive and negative emotions, the processes of neuroautonomic activation [1,7,10,20]. This interpretation is supported by data showing that γ activity in the parietal cortex is involved in a multitude of cognitive reappraisal processes and the control of the emotions, directed to enhancing or suppressing emotional experience, thus supporting both top-down cognitive executive and bottom-up sensory control of the emotional process [27].…”

“…Esta hipótesis mantiene que las personas con dependencia al alcohol mostrarían dificultades en generar señales emocionales adversas asociadas a una respuesta fisiológica (Verdejo-García y Bechara, 2009), lo que, a su vez, puede resultar en una reacción disminuida de la TC ante imágenes negativas. La visualización pasiva de imágenes emocionalmente negativas se asocia, en general, con una deceleración de la TC (Danko, Gracheva, Boytsova y Solovjeva, 2011;Lang et al, 1993;Palomba et al, 2000). La ausencia de una disminución de la TC en respuesta a estímulos negativos en personas con dependencia al alcohol está en línea con estudios que han encontrado una reactividad de la TC disminuida ante estímulos emocionalmente negativos, incluyendo imágenes negativas (Gerra et al, 2003), y ante las consecuencias negativas de violaciones de la moralidad (Carmona-Perera et al, 2013).…”

Alcohol dependence is associated with abnormalities in the processing of emotional signals and impulsive alcohol-seeking behaviours, and these alterations compromise the effectiveness of treatment approaches. However, there is a lack of studies linking the experience of emotions to everyday motivationally relevant stimuli in alcohol-dependent individuals using both autonomic and self-report measures. We analysed heart rate (HR), skin conductance (SC) and subjective emotional reactivity to everyday affective stimuli in alcohol-dependent individuals, and their associations with impulsivity and degree of alcohol consumption. SC and HR were continuously monitored in 28 alcohol-dependent individuals and in 31 non-alcohol healthy controls during passive viewing of pleasant, unpleasant, and neutral emotional pictures. Participants assessed the pictures for valence, arousal, and dominance and completed the Barratt Impulsiveness Scale. Alcohol-dependent individuals showed reduced HR and SC reactivity to both positive and negative emotional stimuli. In the case of SC, this blunted response was associated with impulsivity. Furthermore, alcohol-dependents displayed decoupled physiological and subjective responses, with blunted autonomic responses and normal subjective reports regarding emotional stimuli. Our findings indicate that alcohol-dependent individuals failed to use emotional autonomic feedback in response to natural, emotionally relevant stimuli, and provide initial evidence of the contribution of impulsivity to emotional processing deficits in this population. These results are in keeping with the proposed key role played by emotional experience and impulsivity in substance abuse.

“…This result confirms reports in other studies [3] It was only while reading the SET that these women presented a greater AP in the fast bands (beta 1, beta 2 and gamma) in the temporal areas of both hemispheres. An increased AP in beta 2 and gamma has been associated with positive emotional states induced by reading [50]. In particular, the gamma band has been associated with the processing of emotional stimuli, especially in temporal areas [51].…”

This study explored the cortical functionality in young women while reading a sexually-explicit text. Electroencephalographic activity (EEG) was recorded in heterosexual women while reading either a sexually-explicit text or one with neutral content. Absolute power (AP) and the degree of EEG synchronization among the prefrontal, temporal and parietal cortices were analyzed for the different EEG bands. To evaluate sexual arousal, valence and general activation, Likert-type and Manikin scales were applied. Subjects scored the sexually-explicit text as more pleasurable, and reported greater general activation and sexual arousal than while reading the neutral one. During reading of the sexually-explicit text only, they showed a higher AP in the beta and gamma bands in temporal areas in both hemispheres, and in the theta band in parietal ones, with a lower degree of EEG synchronization between prefronto-temporal areas in the fast bands. Results show that both hemispheres were activated in these sexually-aroused women. The low bilateral synchronization between prefrontal and temporal regions indicates the independent functionality of these cortices, which could be a requirement for inducing and maintaining sexual arousal during reading of sexually-explicit texts in women. These data should broaden our knowledge of the cortical mechanisms that underlie sexual arousal in women.
