Projections of the insular cortex to orbitofrontal and medial prefrontal cortex: A tracing study in the rat

Frontiers in Neuroanatomy, 2023
The dense fiber pathways that connect the insular cortex with frontal cortices are thought to provide these frontal areas with interoceptive information, crucial for their involvement in executive functions.

Electrophysiological Heterogeneity of Fast-Spiking Interneurons: Chandelier versus Basket Cells [PDF]

, 2013
In the prefrontal cortex, parvalbumin-positive inhibitory neurons play a prominent role in the neural circuitry that subserves working memory, and alterations in these neurons contribute to the pathophysiology of schizophrenia.

Prefrontal Planning Latency Associated With Age and Serological Evidence of Microbial Exposure

Chronic Diseases and Translational Medicine, EarlyView.
Planning latency versus age by group. Scatterplot showing individual observations (n = 53) stratified by fibromyalgia status. LOESS smoothing curves with 95% confidence intervals (shaded regions) illustrate the relationship within each group. Overall, rₛ = 0.394 (p = 0.003).

Effect of rs1063843 in theCAMKK2gene on the dorsolateral prefrontal cortex [PDF]

Human Brain Mapping, 2016
Recently, a single nucleotide polymorphism (SNP) in the CAMKK2 gene (rs1063843) was found to be associated with lower expression of the gene in the dorsolateral prefrontal cortex (DLPFC) and with schizophrenia (SCZ) and deficits in working memory and executive function. However, the brain mechanism underlying this association is poorly understood.

Reflex seizures and epilepsy surgery: A network approach case‐based exploration

Epileptic Disorders, EarlyView.
Abstract Context Reflex seizures (RS) are defined by their consistent provocation by specific stimuli, encompassing a broad range from elementary sensory inputs to complex cognitive tasks. While RS are often encountered in clinical practice, their surgical management remains sparsely reported and poorly systematized.

Disruption of Dorsolateral Prefrontal Cortex Decreases Model-Based in Favor of Model-free Control in Humans [PDF]

, 2013
Human choice behavior often reflects a competition between inflexible computationally efficient control on the one hand and a slower more flexible system of control on the other.

Age differences in prefrontal surface area and thickness in middle aged to older adults

Frontiers in Aging Neuroscience, 2016
Age is associated with reductions in surface area and cortical thickness, particularly in prefrontal regions. There is also evidence of greater thickness in some regions at older ages.

Creativity and its link to epilepsy

Epilepsia Open, EarlyView.
Abstract Creative thinking represents one of our highest‐order cognitive processes, involving multiple cortical structures and an intricate interplay between several cortical and subcortical networks. It results in novel ideas that translate to useful products or concepts. The evolutionary purpose of creativity is therefore apparent, as it advances our

Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...
