What is vigilance in neuroscience?
Best insight from top research papers
Vigilance in neuroscience refers to an operator's ability to sustain attention and remain alert for an extended period of time while performing a task. It involves maintaining focus and detecting critical stimuli relevant to the task at hand. Vigilance is crucial in jobs that require monitoring, such as surveillance tasks, security monitoring, and air traffic control . Neuroergonomic studies have shown that vigilance tasks can lead to a decline in performance over time, known as the vigilance decrement . This decline in performance may be due to cognitive fatigue and impairments in executive control . Researchers have explored various methods to counteract the vigilance decrement, including cueing based on task-related or environmental factors . Additionally, studies have investigated the use of neurophysiological measures, such as electroencephalography (EEG) and eye tracking, to assess and improve vigilance levels . Overall, vigilance in neuroscience involves understanding and enhancing an operator's ability to sustain attention and remain alert during prolonged tasks, with the goal of improving performance and reducing errors.

What is vigilance and it importance in post market surveillance?3 answersVigilance is a key component of post-market surveillance and refers to the process of monitoring the safety and performance of medical devices or drugs once they are on the market. It involves the systematic collection and analysis of data to identify any previously unrecognized adverse effects or positive effects. Vigilance is important because it helps to ensure that medical products continue to meet safety and performance standards throughout their entire life cycle, and that any potential risks or issues are identified and addressed in a timely manner. It also helps to protect the users, patients, and the general public from any potential harm or unintended side effects. Post-market surveillance systems, such as the Yellow Card scheme in the UK and the Canada Vigilance Program, have been implemented to facilitate the monitoring and reporting of adverse events and to ensure the ongoing safety and effectiveness of medical products.
What is the importance of vigilance in post market survelliance of medical devices?5 answersVigilance in post-market surveillance of medical devices is of utmost importance to ensure the safety and performance of these devices. It involves the systematic monitoring and reporting of adverse events related to medical devices, which helps in identifying any potential risks or issues that may arise after the devices are placed on the market. By collecting and analyzing data on adverse events, vigilance programs can contribute to the improvement of medical device policies and regulations, leading to higher reliability of diagnosis and treatments. Additionally, vigilance helps in detecting and analyzing malfunctions or changed requirements in a timely manner, allowing manufacturers to take appropriate measures to restore the defined specifications and communicate potential safety risks to users and patients. It also plays a crucial role in harmonizing international standards and promoting the traceability and evidence-based management of medical device performance. Overall, vigilance in post-market surveillance is essential for ensuring the ongoing safety and effectiveness of medical devices throughout their entire product life cycle.
How fixation duration changes as vigilance decrease?5 answersFixation duration changes as vigilance decreases. The ability to sustain attention for extended periods of time, known as vigilance, typically declines over time, resulting in a phenomenon called vigilance decrement. Several factors contribute to the vigilance decrement, including reductions in attentional resources and motivation. Physiological changes, such as changes in electroencephalography (EEG), electrocardiography (ECG), eye movement, and electromyography (EMG), have been studied as indicators of vigilance decrement. However, the relationship between fixation duration and vigilance decrement is not explicitly mentioned in the abstracts provided. Further research is needed to determine the specific changes in fixation duration as vigilance decreases.
What is the impact of hospital vigilantes on the safety of patients and staff?5 answersHospital vigilantes have a significant impact on the safety of patients and staff. The presence of vigilantes has changed the dynamics between patients and hospital staff, leading to threats and comments that create a hostile environment. Additionally, workplace violence in hospitals is a frequent occurrence, with hospital shootings being a particular concern. The aftermath of such incidents results in a loss of trust among staff and patients, hindering the reporting of safety concerns. Furthermore, the stressful and dangerous nature of U.S. hospitals contributes to medical errors, hospital-acquired infections, and staff turnover. Designing hospitals with a focus on safety can help reduce hospital-acquired infections, patient falls, and staff errors. Overall, hospital vigilantes and the associated violence have a detrimental impact on the safety and well-being of both patients and staff.
Does modality of stimulus matter in vigilance decrement?5 answersThe modality of the stimulus does matter in the vigilance decrement. Changing the modality from visual to auditory improved vigilance performance, while changing from auditory to visual decreased performance. Both auditory and visual vigilance tasks showed a decline in performance over time, indicating a vigilance decrement. The results suggest that a right hemispheric system is involved in the functional control of vigilance in both auditory and visual channels. There were indications of modality specificity in vigilance performance, but the degree of coupling between auditory and visual tasks was not as significant as expected. Overall, the findings suggest that modality-specific resources play a role in the vigilance decrement, and changing the modality of the stimulus may have an impact on performance.
What is the hypervigilance and further action?4 answersHypervigilance refers to an enhanced or exaggerated search for environmental stimuli or scan for threatening information. It is observed in certain patient groups, such as those with fibromyalgia (FM), who have lower pain thresholds and tolerance levels compared to controls. The term "hypervigilance" is used to describe this phenomenon, but there are different interpretations of its underlying pathophysiology. Some view it as a restatement of the basic phenomenon, while others see it as an enhanced reaction to a wide range of bodily signs. Research suggests that generalized hypervigilance in FM patients involves greater sensitivity to stimuli, high monitoring of internal and external events, attribution of bodily signs to physiological causes, maladaptive coping with anxiety, and a predisposition to respond to negative experiences with bodily reactions. Further research is needed to explore these components.In the context of delusions, the literature on epistemic vigilance provides insight into the apparent contradiction of excessive credulity and excessive rigidity. Deluded individuals exhibit an imbalance in their treatment of evidence, being overly skeptical of testimony from others while being credulous towards their own perception. This imbalance may be attributed to an evolutionary advantage in being vigilant towards ostensive evidence, information communicated by others. However, in deluded individuals, this vigilance towards sensory and perceptual evidence outweighs the vigilance towards testimonial evidence, resulting in the paradoxical combination of credulity and skepticism.In summary, hypervigilance is characterized by an enhanced search for environmental stimuli or scan for threatening information. It is observed in certain patient groups, such as those with fibromyalgia, and is associated with lower pain thresholds and tolerance levels. The term "hypervigilance" is used to describe this phenomenon, but there are different interpretations of its underlying pathophysiology. In the context of delusions, the literature on epistemic vigilance provides insight into the apparent contradiction of excessive credulity and excessive rigidity. Further research is needed to explore the components of hypervigilance in fibromyalgia patients and to understand the imbalance in the treatment of evidence in deluded individuals.
