Olfactory Bulb Volume Reflects Olfactory Dysfunction and Network Organization: Insights From the Population‐Based Rhineland Study

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory dysfunction is common in aging and an early symptom of neurodegenerative diseases, but how structural (olfactory bulb [OB] volume) and functional (olfactory network [OFN] functional connectivity [FC]) brain features interact to shape odor identification ability remains unclear.

Determining the Minimal Clinically Important Difference of the 40‐Item Smell Identification Test in People With Cystic Fibrosis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) and olfactory dysfunction (OD) are highly prevalent among people with cystic fibrosis (PwCF) and negatively impact quality of life. The 40‐item Smell Identification Test (SIT) is widely used to assess psychophysical olfaction, but a CF‐specific minimal clinically important difference (MCID) has not been ...

Balance and imbalance in dark and bright (OFF and ON) visual channels

Scientific Reports
The visual system uses separate neuron channels to distinguish figures that are darker or brighter than their background. We displayed letters as dark and/or bright pulses, with pulse energy scaled as a function of background energy, and assessed the ...

The self-regulation peculiarity impact to the phenomenon of compensatory discrimination [PDF]

Национальный психологический журнал, 2016
The psychophysical research (N=106) on loudness distinction of tonal signals (method 2AFC) has been carried out. Applying the principle of subject`s activity and qualitative analysis to traditional psychophysical research was accomplished in the ...

Visual Hypersensitivity as a Transdiagnostic Marker of Surgical Pain Response in Arthritis and Chronic Pain Syndromes

Arthritis &Rheumatology, EarlyView.
Objective Nociplastic pain is pain primarily driven by the central nervous system and, unlike nociceptive pain conditions, is thought to be refractory to peripherally directed therapies. Nociplastic pain is also associated with hypersensitivity to painful and other sensory stimuli (such as visual stimuli). Nonpainful sensory measures have not been well

Chromatic Induction in Migraine

Vision, 2021
The human visual system is not a colorimeter. The perceived colour of a region does not only depend on its colour spectrum, but also on the colour spectra and geometric arrangement of neighbouring regions, a phenomenon called chromatic induction ...

Interval Timing Is Altered in Male Nrxn1+/− Mice: A Model of Autism Spectrum Disorder

Autism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is characterized by impaired social interactions and communication, and increased repetitive and stereotypical behavior. Neuroimaging shows functional abnormalities in brain areas involved in temporal processing in autistic individuals, and they also show deficits in interval timing.

The functional role of spatial anisotropies in ensemble perception

BMC Biology
Background The human brain can rapidly represent sets of similar stimuli by their ensemble summary statistics, like the average orientation or size. Classic models assume that ensemble statistics are computed by integrating all elements with equal weight.

Annoyance Penalty Model for Steady-State Broadband Noise with Varying Spectra

Applied Sciences
Noise regulations often apply penalties (e.g., +5 dB) to A-weighted equivalent sound pressure levels (LAeq [dB]) to account for increased annoyance from tonal or impulsive features.

Temporal attention affects contrast response function by response gain

Frontiers in Human Neuroscience, 2023
Orienting attention to a specific point in time has been shown to improve the contrast sensitivity at the attended time point and impair it earlier or later.
