Background: Understanding the functions of different brain areas has represented a major endeavor of contemporary neurosciences. Modern neuroimaging developments suggest cognitive functions are associated with networks rather than with specific areas.
Objectives: The purpose of this paper was to analyze the connectivity of Brodmann area (BA) 46 (anterior middle frontal gyrus) in relation to language.
Methods: A meta-analysis was conducted to assess the language network in which BA46 is involved. The DataBase of Brainmap was used; 19 papers corresponding to 60 experimental conditions with a total of 245 subjects were included.
Results: Our results suggest the core network of BA46. The localization and modules involved suggest BA46 participation in a “frontal language production system" (or extended Broca's system). The depicted BA46 connectivity is also concordant with a minor role in language semantics and language understanding.
Conclusion: It was concluded that BA46 plays a central role in the language production system, most likely related to its executive control.

Planning has been studied in different fields of psychology, including cognitive, developmental, personality, social, and work and organizational research. This article looks at the planning process through the lens of motivation science, and asks the question, What kind of planning can help people reach their goals? We focus on the strategy of making if-then plans (also known as forming implementation intentions). We discuss what kinds of cognitive performance can be enhanced by if-then planning (e.

Ruminative reflection has been linked to enhanced executive control in processing internally represented emotional information, suggesting it may serve as an adaptive strategy for emotion regulation. Investigating the neural substrates of reflection can deepen our understanding of its adaptive properties. This study used network-based statistic (NBS)-Predict methodology to identify resting state functional connectivity (FC)-based predictors of ruminative reflection in a healthy sample.

Background: Diabetes-related cognitive impairment is increasingly recognized as a significant complication, profoundly impacting patients' quality of life. This review aims to examine the pathophysiological mechanisms, clinical manifestations, risk factors, assessment and diagnosis, management strategies, and future research directions of cognitive impairment in diabetes.
Methodology: A comprehensive literature search was conducted using PubMed, Medline, and other medical databases to identify, review, and evaluate published articles on cognitive impairment in diabetes.
The impact of induced stress on reactive and proactive control in depression.

Background: Depression, a widespread mental health issue, is often marked by impaired cognitive control, particularly in managing proactive and reactive processes. The Dual Mechanisms of Control (DMC) framework differentiates between these two modes of cognitive control: proactive control involves sustained goal maintenance, while reactive control is more stimulus-driven and transient. Stress, known to exacerbate cognitive dysfunction in depression, may influence the balance between these control processes, though the specific effects remain poorly understood.

Introduction: Unipolar and bipolar mood disorders in older adults are accompanied by cognitive impairment, including executive dysfunction, with a severe impact on daily life. Up and till now, strategies to improve cognitive functioning in late-life mood disorders (LLMD) are sparse. Therefore, we aimed to assess the efficacy of adaptive, computerized cognitive training (CT) on executive and subjective cognitive functioning in LLMD.
