Two distinct pathological substrates associated with MMSE-pentagons item deficit in DLB and AD
DiscussionThese findings reveal that visuospatial deficits may derive from distinct brain alterations in AD and DLB. We propose that the inabilities to perform correctly the QSPT task is related to altered visuoperceptual process in DLB, and visuospatial process in AD. This is consistent with our results showing hypometabolism in brain system related to visuoperceptual processing, namely the occipital cortex in DLB, and visuospatial processing, namely parietal cortex in AD.

What's “left”? Hemispheric sensitivity to predictability and congruity during sentence reading by older adults
Publication date: Available online 17 August 2019Source: NeuropsychologiaAuthor(s): Kara D. Federmeier, Marta KutasAbstractA number of studies have found that older adults' sentence processing tends not to be characterized by the prediction-related effects attested for young adults. Here, we further probed older adults’ sensitivity to predictability and congruity by recording event-related brain potentials (ERPs) as adults over age 60 read pairs of sentences, which ended with either the expected word, an unexpected word from the same semantic category, or an unexpected word from a different category. Half of the cont...

Clarifying the relationship between trait empathy and action-based resonance indexed by EEG mu-rhythm suppression
Publication date: Available online 17 August 2019Source: NeuropsychologiaAuthor(s): Marissa A. DiGirolamo, Jeremy C. Simon, Kristiana M. Hubley, Alek Kopulsky, Jennifer N. GutsellAbstractSensorimotor resonance, the vicarious activation of the sensory motor system during observation of another's actions, is thought to contribute to important social functions including empathy. Previous research has shown that sensorimotor resonance, as measured by suppression of the electrophysiological (EEG) mu rhythm, is predicted by trait empathy, but findings are inconsistent. Here we report data from a high-powered study (N = 252) ...

Behaviour outcomes in children with epilepsy 1 year after surgical resection of the ventromedial prefrontal cortex
In conclusion, VM lesions in children with epilepsy are associated with behavioural problems but their profile does not differ from that of children with temporal lobe epilepsy. These results are consistent with the concept that seizures arise from epileptogenic networks that may affect multiple cortical areas, even when onset is in a focal site. (Source: Neuropsychologia)

In this study, the causal relationship of the DLPFC in error commission was examined by means of a repetitive transcranial magnetic stimulation protocol (rTMS).

Building the multitasking brain: An integrated perspective on functional brain activation during task-switching and dual-tasking
In this study, we instead integrate two commonly studied substrates of multitasking, task-switching and dual-tasking, within the same procedural context. This method allows not only a direct comparison of performance costs associated with different demand types but also examination of their interaction. We measured functional brain activation in thirty healthy young adults as they completed a block-design version of the task, observing consistent and separable patterns of frontoparietal activation as a function of demand type. Broadly, task-switching was associated with activation of left premotor and inferior parietal reg...
