Objective: Spectral- and temporal-resolution tests are seldom used in clinical practice despite their proven relevance for patients' speech understanding in noise and expected importance for hearing-aid fitting. The aim here was to investigate and compare two clinically applicable tests ('tone test' and 'sweep test') that measure both spectral and temporal resolution simultaneously.
Design: Experiments were conducted monaurally via headphones. After examining test-retest reliabilities and learning effects we compared results from tone and sweep tests to results from conventional spectral and temporal-resolution tests and to speech perception in noise scores.
Study Sample: A group of five normal-hearing listeners (aged 18-42 years, median 19) and 15 (sensorineurally) hearing-impaired listeners (aged 20-68 years, median 56).
Results: It was found that the tone test corresponded much better to the conventional methods than the sweep test. Relating spectral and temporal-resolution results to speech perception in noise scores showed that the tone test seems to be slightly more relevant for speech perception than the sweep test.
Conclusions: It can be concluded that the tone test (after modifications we suggest, based on our findings) is a fast and reliable test that is suitable for measuring spectral and temporal resolution in a clinical setting.

We aimed to study the effect of Parkinson's disease (PD) and motor-cognitive load on the interplay between activation level and spatial complexity. To that end, 68 PD patients and 30 controls underwent electroencephalography (EEG) recording while executing visual single- and dual- Go/No-go tasks. The EEG underwent source localization, followed by parcellation of the neural activity into 116 regions of interest.

The visual environment of sign language users is markedly distinct in its spatiotemporal parameters compared to that of non-signers. Although the importance of temporal and spectral resolution in the auditory modality for language development is well established, the spectrotemporal parameters of visual attention necessary for sign language comprehension remain less understood. This study investigates visual temporal resolution in learners of American Sign Language (ASL) at various stages of acquisition to determine how experience with sign language affects perceptual sampling.

Background: Dementia exhibits abnormal network activity, including altered gamma frequency (30-100 Hz) in Alzheimer's disease (AD). A non-pharmacological, non-invasive approach to AD treatment involves stimulating sensory inputs using gamma band, with 40 Hz as the most effective in eliciting a robust EEG response. Light and sound stimulation at 40 Hz reduces AD pathology in mouse models and improves cognition in humans with AD.

Background: Understanding the neuronal mechanisms of learning and memory is one of the major goals in neurophysiology and neuropsychology. Disorders related to memory consolidation are often the consequences of dynamic plasticity changes, which may lead to a reduction in spine number and density, impairing neural networks. Sleep is one of the major physiological prerequisites for memory consolidation, especially during NREM sleepwhen glymphatic system clearance takes place, too.

Background: Amyotrophic lateral sclerosis (ALS) shares pathological and genetic underpinnings with frontotemporal dementia (FTD). ALS manifests with diverse symptoms, including progressive neuro-motor degeneration, muscle weakness, but also cognitive-behavioural changes in up to half of the cases. Resting-state EEG measures, particularly spectral power and functional connectivity, have been instrumental for discerning abnormal motor and cognitive network function in ALS [1]-[3].
