Disconnected and Hyperactive: A Replication of Sensorimotor Cortex Abnormalities in Patients With Schizophrenia During Proactive Response Inhibition

Christopher J. Wertz, Faith M Hanlon, Nicholas A. Shaff et al. · 2018 · Schizophrenia Bulletin

Inhibitory failure represents a core dysfunction in patients with schizophrenia (SP), which has predominantly been tested in the literature using reactive (ie, altering behavior after a stimulus) rather than proactive (ie, purposefully…

Majority language skill, not measures of bilingualism, predicts executive attention in bilingual children

David Giguere, Daniel J. Dickson, Michelle K. Tulloch et al. · 2021 · Journal of Experimental Child Psychology

Evidence is mixed regarding whether and why bilingual children might be advantaged in the development of executive functions. Five preregistered hypotheses regarding sources of a bilingual advantage were tested with data from 102 Spanish-English bilingual children and 25 English monolingual children who were administered a test of executive attention, the flanker task, at 7, 8, and 9 years of age. Measures of the children's early and concurrent bilingual exposure and their concurrent English and Spanish skill were available from a larger longitudinal study in which these children participated.

Exploring Bottom-Up Visual Processing and Visual Hallucinations in Parkinson's Disease With Dementia

Nicholas Murphy, Alison Killen, Rajnish Kumar Gupta et al. · 2021 · Frontiers in Neurology

Visual hallucinations (VH) are a common symptom of Parkinson's disease with dementia (PDD), affecting up to 65% of cases. Integrative models of their etiology posit that a decline in executive control of the visuo-perceptual system is a primary mechanism of VH generation. The role of bottom-up processing in the manifestation of VH in this condition is still not clear although visual evoked potential (VEP) differences have been associated with VH at an earlier stage of PD. Here we compared the amplitude and latency pattern reversal VEPs in healthy controls ( n = 21) and PDD patients ( n = 34) w

Combined lipid emulsion and ACLS resuscitation following bupivacaine- and hypoxia-induced cardiovascular collapse in unanesthetized swine.

Brent A Bushey, Victor H Auld, John E Volk et al. · 2011 · PubMed

This study examined whether combining lipid emulsion and advanced cardiac life support (ACLS) improves survival in an unanesthetized swine model of bupivacaine- and hypoxia-induced cardiovascular collapse. Arterial and venous catheters and…

Melatonin as a Guardian of Mitochondria: Mechanisms and Therapeutic Potential in Neurodegenerative Diseases

Yanyu Bao, Guoying Miao, Nannan He et al. · 2026 · Biology

Mitochondrial dysfunction is a key early pathological process in neurodegenerative diseases (NDs), leading to oxidative stress, impaired energy metabolism, and neuronal apoptosis prior to the onset of clinical symptoms. Although mitochondria represent important therapeutic targets, effective interventions targeting mitochondrial function remain limited. This review summarizes current evidence regarding the mechanisms by which melatonin protects mitochondria and evaluates its therapeutic relevance, with a primary focus on Alzheimer's disease, Parkinson's disease, and Huntington's disease-the ma

Regulation of LEAP2 by insulin and glucagon in mice and humans

Valdemar Brimnes Ingemann Johansen, Anna Katrina Jógvansdóttir Gradel, Stephanie Kjærulff Holm et al. · 2025 · Cell Reports Medicine

Liver-expressed antimicrobial peptide 2 (LEAP2) is an endogenous antagonist and inverse agonist of the ghrelin receptor, countering ghrelin's effects on cell signaling and feeding. However, despite an emerging interest in LEAP2's…

The burden of secrecy? No effect on hill slant estimation and beanbag throwing.

Diane Pecher, Heleen van Mierlo, Rouwen Cañal‐Bruland et al. · 2015 · Journal of Experimental Psychology General

Slepian, Masicampo, Toosi, and Ambady (2012, Experiment 1) reported that participants who recalled a big secret estimated a hill as steeper than participants who recalled a small secret. This finding was interpreted as evidence that…

Cognitive load, fatigue and aversive simulator symptoms but not manipulated zeitgebers affect duration perception in virtual reality

Magdalena Sabat, Bartosz Haładus, Michał Klincewicz et al. · 2022 · Scientific Reports

The perceived duration of an interval depends on numerous aspects of the passed event both endogenous, including physiological arousal, level of wakefulness, attention, and surprise, as well as exogenous such as valence, salience, or context in the environment. There is some evidence that "time-giving" cues from the environment (zeitgebers) are coupled with time perception. The movement of the sun on the horizon was demonstrated to affect interval perception in a study conducted by Schatzschneider et al. (2016) claiming that the sun's motion is a zeitgeber that influences time perception. In t

Computational genetics analysis of grey matter density in Alzheimer’s disease

Amanda Zieselman, Jonathan Fisher, Ting Hu et al. · 2014 · BioData Mining

BACKGROUND: Alzheimer's disease is the most common form of progressive dementia and there is currently no known cure. The cause of onset is not fully understood but genetic factors are expected to play a significant role. We present here a bioinformatics approach to the genetic analysis of grey matter density as an endophenotype for late onset Alzheimer's disease. Our approach combines machine learning analysis of gene-gene interactions with large-scale functional genomics data for assessing biological relationships. RESULTS: We found a statistically significant synergistic interaction among t
