DeepFoG: An IMU-Based Detection of Freezing of Gait Episodes in Parkinson's Disease Patients via Deep Learning.

Front Robot AI 2021 7;8:537384. Epub 2021 May 7.

Department of Electrical and Computer Engineering, Aristotle University of Thessaloniki, Thessaloniki, Greece.

Freezing of Gait (FoG) is a movement disorder that mostly appears in the late stages of Parkinson's Disease (PD). It causes incapability of walking, despite the PD patient's intention, resulting in loss of coordination that increases the risk of falls and injuries and severely affects the PD patient's quality of life. Stress, emotional stimulus, and multitasking have been encountered to be associated with the appearance of FoG episodes, while the patient's functionality and self-confidence are constantly deteriorating.

Listeners with congenital amusia are sensitive to context uncertainty in melodic sequences.

Neuropsychologia 2021 Jun 6;158:107911. Epub 2021 Jun 6.

Lyon Neuroscience Research Center, CNRS, UMR5292; INSERM, U1028, Lyon, F-69000, France; University Lyon 1, Lyon, F-69000, France.

In typical listeners, the perceptual salience of a surprising auditory event depends on the uncertainty of its context. For example, in melodies, pitch deviants are more easily detected and generate larger neural responses when the context is highly predictable than when it is less so. However, it is not known whether amusic listeners with abnormal pitch processing are sensitive to the degree of uncertainty of pitch sequences and, if so, whether they are to a different extent than typical non-musician listeners.

Sustained pupil responses are modulated by predictability of auditory sequences.

J Neurosci 2021 Jun 1. Epub 2021 Jun 1.

Ear Institute, University College London, London WC1X 8EE, UK.

The brain is highly sensitive to auditory regularities and exploits the predictable order of sounds in many situations, from parsing complex auditory scenes, to the acquisition of language. To understand the impact of stimulus predictability on perception, it is important to determine how the detection of predictable structure influences processing and attention. Here we use pupillometry to gain insight into the effect of sensory regularity on arousal. Read More

Auditory Temporal Processing in Dancers.

Percept Mot Skills 2021 Jun 2:315125211021210. Epub 2021 Jun 2.

The New York Otolaryngology Group, New York, United States.

While many studies have examined the auditory abilities of musicians, this study uniquely asks whether dance training, a similar yet understudied type of early-life training, also benefits auditory abilities. We focused this investigation on temporal resolution, given the importance of subtle temporal cues in synchronizing movement. We found that, compared to untrained controls, novice adult dancers who have trained continuously since childhood had enhanced temporal resolution, measured with a gap detection task. Read More

Decoding Brain Responses to Names and Voices across Different Vigilance States.

Sensors (Basel) 2021 May 13;21(10). Epub 2021 May 13.

Cognition and Consciousness Research, Laboratory for Sleep, Department of Psychology, University of Salzburg, Hellbrunner Strasse 34, 5020 Salzburg, Austria.

Past research has demonstrated differential responses of the brain during sleep in response especially to variations in paralinguistic properties of auditory stimuli, suggesting they can still be processed "offline". However, the nature of the underlying mechanisms remains unclear. Here, we therefore used multivariate pattern analyses to directly test the similarities in brain activity among different sleep stages (non-rapid eye movement stages N1-N3, as well as rapid-eye movement sleep REM, and wake).

Event-related potentials in insomnia reflect altered perception of sleep.

Sleep 2021 Jun 1. Epub 2021 Jun 1.

Medical Center - University of Freiburg, Department of Psychiatry and Psychotherapy, Section of Clinical Psychology and Psychophysiology, Hauptstraße, Freiburg, Germany.

Study Objectives: Insomnia is defined by the subjective complaint of poor sleep as well as daytime impairments. Since polysomnography (PSG) typically shows only modest sleep impairment, some still unidentified property of sleep, not mirrored in PSG, may be modified in insomnia.One possible mechanistic hypothesis is that insomnia patients may be more sensitive to inevitably occurring internal or external stimuli during the night, causing brief sleep disruptions then perceived as wake time.

Task-dependent audiovisual temporal sensitivity is not affected by stimulus intensity levels.

Vision Res 2021 May 28;186:71-79. Epub 2021 May 28.

Department of Psychology, University of Nevada, 1664 N. Virginia St., Reno, NV 89557, USA.

Flexibility and robustness of multisensory temporal recalibration is paramount for maintaining perceptual constancy of the surrounding natural world. Different environments impart various impediments, distances and routes that alter the propagation times of sight and sound cues comprising a multimodal event. One's ability to rapidly calibrate and account for these external variations allows for maintained perception of synchrony which is crucial for coherent and consistent perception. Read More

Early differences in auditory processing relate to Autism Spectrum Disorder traits in infants with Neurofibromatosis Type I.

J Neurodev Disord 2021 05 28;13(1):22. Epub 2021 May 28.

Centre for Brain and Cognitive Development, Birkbeck, University of London, Henry Wellcome Building, Malet Street, London, WC1E 7HX, UK.

Background: Sensory modulation difficulties are common in children with conditions such as Autism Spectrum Disorder (ASD) and could contribute to other social and non-social symptoms. Positing a causal role for sensory processing differences requires observing atypical sensory reactivity prior to the emergence of other symptoms, which can be achieved through prospective studies.

Methods: In this longitudinal study, we examined auditory repetition suppression and change detection at 5 and 10 months in infants with and without Neurofibromatosis Type 1 (NF1), a condition associated with higher likelihood of developing ASD. Read More

Self-Related Stimuli Decoding With Auditory and Visual Modalities Using Stereo-Electroencephalography.

Front Neurosci 2021 4;15:653965. Epub 2021 May 4.

State Key Laboratory of Mechanical System and Vibration, School of Mechanical Engineering, Shanghai Jiao Tong University, Shanghai, China.

Name recognition plays important role in self-related cognitive processes and also contributes to a variety of clinical applications, such as autism spectrum disorder diagnosis and consciousness disorder analysis. However, most previous name-related studies usually adopted noninvasive EEG or fMRI recordings, which were limited by low spatial resolution and temporal resolution, respectively, and thus millisecond-level response latencies in precise brain regions could not be measured using these noninvasive recordings. By invasive stereo-electroencephalography (SEEG) recordings that have high resolution in both the spatial and temporal domain, the current study distinguished the neural response to one's own name or a stranger's name, and explored common active brain regions in both auditory and visual modalities.

When two is worse than one: The deleterious impact of multisensory stimulation on response inhibition.

PLoS One 2021 20;16(5):e0251739. Epub 2021 May 20.

Brain & Cognition Research Center (CerCo), University of Toulouse 3 -CNRS, Toulouse, France.

Multisensory facilitation is known to improve the perceptual performances and reaction times of participants in a wide range of tasks, from detection and discrimination to memorization. We asked whether a multimodal signal can similarly improve action inhibition using the stop-signal paradigm. Indeed, consistent with a crossmodal redundant signal effect that relies on multisensory neuronal integration, the threshold for initiating behavioral responses is known for being reached faster with multisensory stimuli.
