Temporal lobe epilepsy alters neural responses to human and avatar facial expressions in the face perception network

The aim of our event-related fMRI study was to compare brain activation differences in people with epilepsy and controls during the processing of fearful and neutral dynamic expressions displayed by human or avatar faces. Our fMRI results show that people with TLE exhibited reduced response differences between human and avatar fearful expressions in the dorsal pathway of the face perception network (STS and inferior frontal gyrus) as well as in the medial prefrontal cortex. Taken together, these findings suggest that brain responses to dynamic facial expressions are altered in people with TLE compared to neurologically healthy individuals—regardless of whether the face is human or computer-generated.

Impairment of eye emotion discrimination in benign childhood epilepsy with centrotemporal spikes: A neuropsychological study

To explore the characteristics and related factors of emotional recognition impairment in BECT patients, we conducted eye emotion discrimination studies on the newly diagnosed BECT and the postremission BECT, respectively, and found that the discrimination of sadness, fear, and disgust in newly diagnosed BECT patients has been impaired, and it is negatively correlated with the age of onset. More younger the age of onset, more severe the damage. However, there is no obvious damage to the discrimination of sadness, fear, and disgust in patients with BECT after remission. This result indicates that although BECT patients have impairment of eye emotion discrimination at the early stage of the disease, it can be returned to normal as the disease is relieved.

When reintegration fails: Stigmatization drives the ongoing violence of ex-combatants in Eastern Democratic Republic of the Congo

This article showed that stigmatization presents as additional burden for ex-combatants in Eastern DRC beyond posttraumatic experiences. Rejective attitudes toward ex-combatants form the basis of stigmatization and by predicting both mental health problems and aggression present as social drivers of the cycles of violence. Our study demonstrates the importance for intervention programming that combines individual treatment with interventions including ex-combatants' social environment.

Task-induced brain functional connectivity as a representation of schema for mediating unsupervised and supervised learning dynamics in language acquisition

Based on the schema theory advanced by Rumelhart and Norman, we shed light on the individual variability in brain dynamics induced by hybridization of learning methodologies, particularly alternating unsupervised learning and supervised learning in language acquisition. Functional magnetic resonance imaging was performed to identify the functional network connections for schema updating by alternately using unsupervised and supervised artificial grammar learning tasks to segment potential words. The default mode network represented the first stage of spontaneous unsupervised learning, and the wrap-up accomplishment for successful subjects of the whole hybrid learning in concurrence with the task-related auditory language networks.

Conscious sedation compared to general anesthesia for intracranial mechanical thrombectomy: A meta-analysis

What's already known about this topic?Endovascular therapy is the standard of care for severe acute ischemic stroke caused by large-vessel occlusion in the anterior circulation, but there is a debate on the optimal anesthetic approach during this therapy. Meta-analyses of observational studies suggest that general anesthesia increases disability and death compared with conscious sedation However, their results are conflicting. This meta-analysis study was performed to assess the relationship between the effects of general anesthesia compared to conscious sedation during endovascular therapy for acute ischemic stroke.What does this article add?General anesthesia has no independent relationship compared to conscious sedation during the endovascular therapy for acute ischemic stroke with a relative relationship favoring general anesthesia only in decreasing the symptomatic intracranial hemorrhage.This relationship encouraged us to recommend either anesthetic strategy during the endovascular therapy for acute ischemic stroke with no possible fear of higher complication.

On the processing of optimal performances: Studying arousal evoked by being correct and fast

  • First Published: 07 May 2021
On the processing of optimal performances: Studying arousal evoked by being correct and fast

Optimal performance, like being correct and fast, leads to enhanced response-related brain activity, increased physiological arousal, and modulations in processing subsequently presented emotional faces. Since these properties are similar to those of error processing, the monitoring system is sensitive to both better-than-expected and worse-than-expected performance. This sensitivity might lead to learning from the negative reinforcement of errors and the positive reinforcement of optimal responses.

Depression and anxiety symptoms are related to pain and frailty but not cognition or delirium in older surgical patients

Preoperative mood symptoms were related to physical pain and frailty. Taken together, these suggest that in patients without a formal psychiatric diagnosis, preoperative mood symptoms are related to physical state rather than a harbinger of early cognitive decline. Future studies are needed to understand the nature of the relationship between mood symptoms and physical state in surgical patients.

Is obsessive–compulsive personality disorder related to stress-related exhaustion?

Recovery from stress-related diagnoses can, in some cases, be long-lasting and several different factors could be related to such a lengthy recovery. The aim of this study was to investigate whether recovery from exhaustion disorder (ED) is associated with OCPD in 147 former patients with ED. The main result is that patients with residual clinical ED report OCPD to a greater extent compared with patients who do not longer fulfill the clinical criteria for ED, 7-10 years after seeking care. Patients with OCPD that have not recovered report “excessive devotion to work” to a higher degree than patients with OCPD that have recovered.

Co-activation pattern alterations in autism spectrum disorder–A volume-wise hierarchical clustering fMRI study

Co-activation patterns (CAPs) of resting state brain activity varyingly contain both default mode network (DMN)-positive and default mode network-negative brain state properties. With hierarchical clustering, they can be divided into shorter substates. When applied in autism spectrum disorder, this method showed simultaneous visual network and either dorsal attention or DMN overactivation during DMN-negative CAPs. Nonsequential volume gathering into CAPs provides an alternative to sliding window analysis.

Cerebral blood flow impairment and cognitive decline in heart failure

One of the postulated mechanisms underlying cognitive decline in chronic heart failure is chronic regional hypoperfusion of critical brain areas. Cognitive function may be further compromised by microvascular damage due to cardiovascular risk factors in chronic heart failure patients. Cerebral blood flow assessment is proposed for early recognition of patients at risk of cognitive decline and could guide further therapeutic strategy.

The relationship between body image and emotional and cognitive impairment after brain damage: A preliminary study

Body image is a person's perception of the aesthetics or sexual attractiveness of their own body. After brain damage, the person is subjected to several physical changes with heavy consequences on both physical and emotional domains. It can lead to a dysfunction of the body image and to the risk to compromise cognitive recovery. Notably, this study confirms the relationship between body image and cognitive deficits in ABI patients, especially noticeable in vascular patients.

Mendelian randomization suggests that head circumference, but not birth weight and length, associates with intelligence

We performed a Mendelian randomization study to investigate the causal effects of infant head circumference, birth length, and birth weight on human intelligence by extracting genetic association datasets from large-scale genome-wide association studies of birth parameters and human intelligence. Our findings suggest that that head circumference, but not birth weight and length, is associated with intelligence, which might indicate that that brain development rather than general fetal growth was responsible for the development of intelligence.

Allophonic perception of VOT contrasts in Spanish children with dyslexia

Spanish children with dyslexia exhibit a general deficit in the perception of the voicing feature on three different VOT continua (ba/pa, de/te, and di/ti). These children also exhibit a higher sensitivity in the discrimination of allophonic features, but only for the stimulus continuum that was based on a nonlexical contrast (ba/pa). Fitting a neural network model to the data suggests that allophonic perception is due to a deficit in “subharmonic coupling” between high-frequency networks.
