Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California Attention, working-memory, planning, impulse control, inhibition, and mental flexibility are important components of human cognition that are often referred to as executive functions. Autism spectrum disorder is a developmental disorder that is characterized by impairments in social interaction, communication, and repetitive behaviors. It is a disorder that lasts a lifetime, and is thought to affect...

Source: Laboratories of Nicholaus Noles and Judith Danovitch—University of Louisville Infants are born with amazing cognitive resources at their disposal, but they don’t know how to use them effectively. In order to harness the power of their brains, humans must develop high-level cognitive processes that manage basic brain functions. These processes make up what psychologists refer to as executive function. Executive function is a key factor in many self-regulatory behaviors, including forming...

Source: Cheah, M., et al. Dorsal Root Ganglion Injection and Dorsal Root Crush Injury as a Model for Sensory Axon Regeneration. J. Vis. Exp. (2017).This video demonstrates a step-by-step procedure for injecting a viral suspension into the dorsal root ganglia (DRGs) and inducing a controlled axonal injury via a dorsal root crush in an anesthetized rat. The protocol involves exposing the DRGs, delivering a growth-promoting viral vector to facilitate axonal regeneration, and severing axonal...
FAQs
Its interconnected frontal and parietal regions help maintain the task goal while selecting information relevant to that goal. Working memory keeps important instructions or task demands available, and cognitive control uses them to guide planning and action. This coordination allows behavior to remain directed toward an objective even when sensory input or competing responses could disrupt performance.
Attention shifting allows the system to redirect processing when task demands change. Frontal and parietal regions help select newly relevant information while reducing the influence of distractions or competing responses. This flexibility is important for moving between subtasks, responding to updated information, and adjusting goal-directed behavior rather than continuing an outdated action.
Executive regions cannot guide behavior effectively in isolation. Communication with sensory systems supplies information about the current situation, while interaction with motor systems helps translate selected goals into actions. Studying these connections clarifies how attention, planning, and cognitive control influence both what information is prioritized and how an appropriate response is organized.
Working memory keeps task-relevant information available, planning organizes possible actions, and cognitive control regulates which actions should proceed. Their interaction supports complex behavior by linking an internal task goal with selected information and an appropriate response. Examining these functions together is more informative than treating attention, memory, or planning as completely separate processes.
Researchers examine its organization and activity while considering behaviors that require attention, working memory, planning, shifting, or suppression of competing responses. These task demands provide ways to relate network activity to goal-directed performance. Comparing activity and behavior across different cognitive requirements can reveal how the system contributes to complex task management.
Research on the dorsal executive system can help explain how people maintain goals, select relevant information, and regulate actions while learning or making decisions. Because these activities depend on coordinated attention, working memory, planning, and control, examining the network provides a framework for relating brain organization and activity to changes in cognitive performance.
Aging research examines this system because attention, working memory, planning, and cognitive control are central to complex task performance. Studying its organization and activity can help investigators relate age-associated changes to the brain processes that support goal maintenance, information selection, attention shifts, and regulation of competing responses.
Researchers examine the organization and activity of the system in conditions that affect executive function. Focusing on attention, working memory, planning, cognitive control, and suppression of competing responses can help characterize how altered network function relates to difficulties with goal-directed behavior. This approach supports comparisons between typical and affected cognitive performance.
