Is supplementary motor area involved in automatic control of behavior?

Ignacio Obeso, principal investigator of the research project 230/18 - Unraveling the mechanisms behind automatic and emotional control: Psychophysiological, cortical excitability and functional connectivity measures, supported by the BIAL Foundation, aimed to test the possible direct role of supplementary motor area (SMA) in automatic and voluntary response inhibition by resourcing to two noninvasive brain stimulation (NIBS) inhibitory techniques over SMA, namely repetitive transcranial magnetic stimulation (rTMS) and transcranial static magnetic field stimulation (tSMS). Participants received both real and sham NBS techniques over SMA. No relevant impact of treatment (rTMS, tSMS) or condition (real, sham) was seen in the training or test phases of a go/no-go learning task and a stop signal task. It seems that SMA has a reduced or indirect involvement in automatic control of behavior. These results are detailed in the paper The supplementary motor area and automatic cognitive control: Lack of evidence from two neuromodulation techniques published in the Journal of Cognitive Neuroscience.

When psychotic-like experiences become distressing?

Evidence suggests that psychotic-like experiences (PLEs) exist along a continuum progressing from benign subclinical phenomena at one end to severe psychotic symptoms at the other. Among children, PLEs are common and typically benign, but in some cases, they can be distressing and functionally impairing. In the scope of the research project 194/12 - Characterising developmental trajectories of brain function from childhood into adolescence, supported by the BIAL Foundation, Kristin Laurens aimed to examine whether the likelihood of distressing or impairing PLEs differed according to the type of co-occurring psychopathology symptoms. It was observed that children with co-occurring internalising and/or externalising problems had greater odds of distressing and/or impairing PLEs compared to children without co-occurring psychopathology (PLEs only). The implications of these results are discussed in the article Increased likelihood of distressing and functionally impairing psychotic-like experiences among children with co-occurring internalising and externalising problems published in the journal Schizophrenia Research.

Effects of aging on face processing

In the scope of the research project 249/16 - Healthy aging and economic decision-making: neuropsychophysiological examination of the affect-integration-motivation framework of decision-making in aging brain, supported by the BIAL Foundation, João Marques-Teixeira and colleagues studied the impact of aging on face processing. It was observed that older adults, compared to younger adults, engage additional neural resources during the visualization of facial expressions of emotion, as well as non-facial stimuli (houses and mugs). Aging may hamper the neural processing of facial expressions of emotion, and this difficulty may be exacerbated during the identification of emotions from faces of their own-age peers. More results are available in the paper Effects of aging on face processing: An ERP study of the own-age bias with neutral and emotional faces published in Cortex.
