Longitudinal changes of resting-state functional connectivity of amygdala following fear learning and extinction
Publication date: Available online 9 January 2020Source: International Journal of PsychophysiologyAuthor(s): Olga Martynova, Alina Tetereva, Vladislav Balaev, Galina Portnova, Vadim Ushakov, Alexey IvanitskyAbstractAltered functional connectivity of the amygdala has been observed in a resting state immediately after fear learning, even one day after aversive exposure. The persistence of increased resting-state functional connectivity (rsFC) of the amygdala has been a critical finding in patients with stress and anxiety disorders. However, longitudinal changes in amygdala rsFC have rarely been explored in healthy participan...

Simple additions: Dissociation between retrieval and counting with electrophysiological indexes
Publication date: Available online 10 January 2020Source: International Journal of PsychophysiologyAuthor(s): Gloria Tejero, Pedro MacizoAbstractThere is current debate about the way adult individuals solve simple additions composed of one-digit operands. There are two opposing views. The first view assumes that people retrieve the result of additions from memory, whilst the second view states that individuals use automatized counting procedures. Our study aimed to dissociate between these two hypotheses. To this end, we analysed the type of problem effect when participants resolved simple additions by comparing additions ...

Perceptual process for the early detection of humans remains intact even under a heavy attentional load: An ERP study
We examined the ability of humans to detect other humans under situations when human images were presented as task-irrelevant stimuli. We measured the anterior N2 elicited by the onset of photographs with and without human images as an indicator of early processing for the detection of humans. We also manipulated attentional loads (low and high loads in Experiments 1 and 2, respectively) when viewing the images to examine the effects of attention. The results indicated that the anterior N2 elicited by images that included humans was larger than that elicited by images that did not include humans, even when the attentional ...

Theta-burst stimulation and frontotemporal regulation of cardiovascular autonomic outputs: The role of state anxiety
Publication date: Available online 7 January 2020Source: International Journal of PsychophysiologyAuthor(s): Tasha Poppa, Sara de Witte, Marie-Anne Vanderhasselt, Antoine Bechara, Chris BaekenAbstractDysregulation of autonomic cardiovascular homeostasis is an important cardiological and neurological risk factor. Cortical regions including the prefrontal and insular cortices exert tonic control over cardiovascular autonomic functions. Transcranial Magnetic Stimulation (TMS) may be a suitable approach for studying top-down control of visceromotor processes. However, there is inconsistent evidence as to whether TMS can modify...

The enhancing effect of incongruent verbal priming stimuli on the CIT effect with pictorial probes in the P300-based complex trial protocol
Publication date: Available online 2 January 2020Source: International Journal of PsychophysiologyAuthor(s): Tingting Sui, Evan Sitar, J. Peter Rosenfeld, Elena Labkovsky, Anne Ward, Elena DavydovaAbstractPrevious research indicated that certain types of incongruent verbal priming enhance responding to the subsequent (primed) stimuli. By priming participants in a P300-based Concealed Information Test(CIT), we examined the possible enhancement effects of priming stimuli in the P300 based Complex Trial Protocol (CTP) for face recognition. Participants were divided into two groups: one group with priming and one control group...
