Neuroinflammation, meaning an inflammatory process primarily occurring within the central nervous system (CNS), is thought to be associated with the pathogenesis of psychiatric disorders including schizophrenia (SC), although existing evidence is sometimes contradictory. This review critically summarizes the existing data on neuroinflammation and possible neuroinflammatory mechanisms in the pathogenesis of SC. Despite heterogeneity and inconsistency, the existing evidence indicates dysregulation of inflammatory genes and infiltration of the CNS parenchyma by immune cells, disturbances in the b

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.

Electroencephalography (EEG)-based emotion recognition is increasingly pivotal in the realm of affective brain-computer interfaces. In this paper, we propose TSANN-TG (temporal-spatial attention neural network with a task-specific graph), a novel neural network architecture tailored for enhancing feature extraction and effectively integrating temporal-spatial features. TSANN-TG comprises three primary components: a node-feature-encoding-and-adjacency-matrices-construction block, a graph-aggregation block, and a graph-feature-fusion-and-classification block. Leveraging the distinct temporal sca

Perceptual experience depends on recurrent interactions between lower and higher cortices. One theory, predictive coding, posits that feedback from higher to lower brain regions decreases neuronal activity predicted by higher-level representations. Despite the widespread adoption of predictive coding in neuroscience, the correspondence to neurophysiological findings in sensory cortices remains elusive. Here, we review how the canonical patterns of intra- and inter-cortical interactions that occur during perception and shifts of attention deviate from those predicted by predictive coding. We ar

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

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

The Bayesian brain hypothesis-the idea that neural systems implement or approximate Bayesian inference-has become a dominant framework in cognitive neuroscience over the past two decades. While mathematically elegant and conceptually unifying, this paper argues that the hypothesis occupies an ambiguous territory between useful metaphor and testable, biologically plausible mechanistic explanation. We critically examine the key claims of the Bayesian brain hypothesis, highlighting issues of unfalsifiability, biological implausibility, and inconsistent empirical support. The framework's remarkabl

Abstract Some neural representations change across multiple timescales. Here we argue that modeling this “drift” could help explain the spacing effect (the long-term benefit of distributed learning), whereby differences between stored and current temporal context activity patterns produce greater error-driven learning. We trained a neurobiologically realistic model of the entorhinal cortex and hippocampus to learn paired associates alongside temporal context vectors that drifted between learning episodes and/or before final retention intervals. In line with spacing effects, greater drift led t

Insect metamorphosis occurs in two main forms, hemimetaboly (simple) and holometaboly (complete), both regulated by hormonal and genetic pathways involving the transcription factors Krüppel homolog 1 (Kr-h1), Broad-Complex (BR-C), and Ecdysone-induced protein 93F (E93). The BTB-zinc finger protein Chronologically inappropriate morphogenesis (Chinmo), recently identified in the fruit fly Drosophila melanogaster, an holometabolan, as a larval state maintainer, was studied here in the German cockroach, Blattella germanica, an hemimetabolan. We also examined another BTB transcription factor, Abrup

Objective While emerging evidence links glymphatic dysfunction to cerebral small vessel disease (CSVD), its clinical relevance remains poorly defined. This study aimed to investigate the relationships among glymphatic function, perivascular space (PVS), and cognitive performance in CSVD. Methods We enrolled 120 CSVD patients [52 with no cognitive impairment (CSVD-NCI) and 68 with mild cognitive impairment (CSVD-MCI)] and 40 healthy controls (HCs). Glymphatic function was assessed using the left ALPS index derived from diffusion tensor imaging analysis along the perivascular space (DTI-ALPS). G

Abstract Alzheimer’s disease (AD) and frontotemporal dementia (FTD) are two major causes of dementia, with overlapping clinical and pathophysiological characteristics. We investigated whether resting-state EEG functional connectivity could distinguish AD, FTD, and healthy controls (HC) using a stacked ensemble learning approach. A publicly available dataset (openneuro.org/datasets/ds004504) was used to extract multiple connectivity metrics across frequency bands. Base classifiers were trained using the Fisher’s Geodesic Minimum Distance to Mean (FgMDM) approach with Euclidean or Riemannian dis

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

Huntington's disease (HD) is the most common autosomal dominant neurodegenerative disorder, characterized by a triad of motor dysfunction, cognitive decline, and psychiatric disturbances. While recent efforts have focused on developing disease-modifying therapies, no treatment has yet demonstrated clinical efficacy. As a result, symptomatic treatment remains the cornerstone of care. However, high-quality evidence from large randomized trials is limited, and therapeutic decisions must rely on clinical expertise and extrapolation from other neurological or psychiatric conditions.

The cortex generates diverse neural dynamics, ranging from broadband fluctuations to narrowband oscillations at specific frequencies. Here, we investigated whether broadband and oscillatory dynamics play different roles in the encoding and transmission of visual information. We used information-theoretical measures to dissociate neural signals sharing common information (i.e., redundancy) from signals encoding complementary information (i.e., synergy). We analyzed electrocorticography (ECoG) and local field potentials (LFP) in the visual cortex of human and non-human primates (macaque) to inve

Diffusion tensor image analysis along the perivascular space (DTI-ALPS) was originally developed and defined as a noninvasive diffusion MRI method intended to evaluate glymphatic function and is now widely used in neuroimaging research. However, accumulating evidence suggests that the biological meaning of the ALPS index is more complex than initially assumed as a simple marker of glymphatic function. The ALPS index does not directly measure whole-brain fluid transport but rather reflects localized directional diffusivity based on the Brownian motion of water molecules. Its value is strongly i
