Does attention to cardiac sensations modulate heartbeat-evoked potentials even ...
Braga, Patrícia Vilela; Vieira, Beatriz; Carina, Fernandes; Barbosa, Fernando; Santos, Fernando Ferreira; Pereira, Mariana R.; Rocha, Nuno BarbosaHeartbeat-evoked potentials (HEP) have been shown to be modulated by attentional focus (cardiac vs. exteroceptive attention), suggesting that HEP are a neural correlate of interoceptive prediction errors. However, this effect has not been consistently replicated, and differences in cognitive effort when contrasting interoceptive vs. exteroceptive attention may be a confounding factor. We devised a modified Hear...
The psychopathic heart: empathy, interoception, and psychopathy traits in adole...
Marinho, Elisabete; Alves, Isabel; Pereira, Mariana R.; Rocha, Nuno; Barbosa, Fernando; Campos, CarlosThe link between empathy and psychopathy phenotypes (grandiose-manipulative, callous-unemotional and impulsive-irresponsible) as well as its underlying mechanisms, are far from being consensual, especially in developmental samples. To explore the differential associations between psychopathy phenotypes, empathy domains (cognitive and affective), and interoception in a community sample of adolescents. 64 adolesc...
Alpha and theta intensive neurofeedback protocol for age-related cognitive defi...
Reis, Joana Vanessa Santos; Portugal, A.; Pereira, Mariana R.; Dias, Nuno Sérgio MendesWith the growing life expectancy, the number of elderly people is increasing tremendously worldwide. The progressive decrease of synaptic plasticity and neuronal interconnectivity in the ageing brain, concomitant with alterations in key cognitive abilities such as working memory and attention, may be delayed, stopped or reversed by neurorehabilitation. Hence, current approaches used to modify cognitive capabili...
