AI SummaryA 14-year-old girl was diagnosed with nonepileptic events after a diagnostic evaluation for recurrent abdominal pain. However, her long-term EEG recording revealed normal developmental variants that should be recognized to avoid misdiagnosis.A 14-year-old girl presented to the epilepsy monitoring unit for diagnostic evaluation of recurrent episodic abdominal pain. During the admission, multiple typical episodes… Continue reading Teaching NeuroImage: Pictures of Health in Pediatric EEG

Perturbed Information Processing Complexity in Experimental Epilepsy
AI SummaryThe study explores how epilepsy affects information processing in the brain, specifically in the hippocampus and entorhinal cortex. It finds that the organization and composition of information storage and sharing are disrupted in epilepsy, potentially contributing to cognitive deficits and comorbidities associated with the condition.Comorbidities, such as cognitive deficits, which often accompany epilepsies, constitute… Continue reading Perturbed Information Processing Complexity in Experimental Epilepsy
KCNQ2/3 Gain-of-Function Variants and Cell Excitability: Differential Effects in CA1 versus L2/3 Pyramidal Neurons
AI SummaryGOF variants in potassium channels KCNQ2 and KCNQ3 can lead to hyperexcitability disorders. The R201C variant in KCNQ2 causes hyperexcitability in layer 2/3 pyramidal neurons and hypoexcitability in CA1 pyramidal neurons. The R231C variant in KCNQ3 has similar effects. This study reveals the complexity of KCNQ2 and KCNQ3 channels in the forebrain and provides… Continue reading KCNQ2/3 Gain-of-Function Variants and Cell Excitability: Differential Effects in CA1 versus L2/3 Pyramidal Neurons

Machine learning and EEG can classify passive viewing of discrete categories of visual stimuli but not the observation of pain
AI SummaryMachine learning has shown promise in classifying physical pain from non-pain states using EEG data, but more research is needed for its application in this context.Previous studies have demonstrated the potential of machine learning (ML) in classifying physical pain from non-pain states using electroencephalographic (EEG) data. However, the application of ML to EEG data… Continue reading Machine learning and EEG can classify passive viewing of discrete categories of visual stimuli but not the observation of pain
Revolutionizing brain monitoring and stimulation with thin-film neural electrodes
AI SummaryFlexible thin-film electrodes placed on brain tissue improve epilepsy diagnosis and treatment by accurately matching the properties of brain tissue, resulting in better performance during recordings and neural stimulation.Flexible thin-film electrodes placed directly on brain tissue show promise for the diagnosis and treatment of epilepsy. Thanks to an innovative yet straightforward design, these durable… Continue reading Revolutionizing brain monitoring and stimulation with thin-film neural electrodes
The Influence of Prestimulus 1/f-Like versus Alpha-Band Activity on Subjective Awareness of Auditory and Visual Stimuli
AI SummaryAlpha rhythmic activity, specifically changes in broadband activity, may be as effective as narrowband alpha activity in predicting subsequent visual detection. These findings suggest the need for a re-examination of existing data on alpha band dynamics and may have significant implications for our understanding of alpha rhythmic activity.Alpha rhythmic activity is often suggested to… Continue reading The Influence of Prestimulus 1/f-Like versus Alpha-Band Activity on Subjective Awareness of Auditory and Visual Stimuli
Evidence Accumulation Rate Moderates the Relationship between Enriched Environment Exposure and Age-Related Response Speed Declines
AI SummaryOlder adults who are exposed to enriched environments (EEs) have higher levels of cognitive function even with compromised brain health. A study using a decision task with electroencephalography (EEG) found that the efficiency of sensory evidence accumulation determines the preservation of response speed in older adults. The mitigating effect of EE on age-related decline… Continue reading Evidence Accumulation Rate Moderates the Relationship between Enriched Environment Exposure and Age-Related Response Speed Declines
Suppressive Control of Incentive Salience in Real-World Human Vision
AI SummaryHumans are able to strategically control their attention to reward-associated objects, suppressing their salience and directing attention to more useful objects. This control may play a role in conditions like eating disorder and addiction.Reward-related activity in the dopaminergic midbrain is thought to guide animal behavior, in part by boosting the perceptual and attentional processing… Continue reading Suppressive Control of Incentive Salience in Real-World Human Vision
Examining the National Representativeness of the Axon Registry: A Neurology-Specific Patient Registry
AI SummaryThe text discusses a study that compared the Axon Registry, a data registry for neurology providers, with two publicly available data sets. The study found that the Axon Registry had similar demographics and neurologic conditions compared to the national data sets. The study suggests that recruiting more and diverse neurology providers will improve the… Continue reading Examining the National Representativeness of the Axon Registry: A Neurology-Specific Patient Registry
