Nested Selves: Self‐Organization and Shared Markov Blankets in Prenatal Development in Humans

Topics in Cognitive Science, EarlyView., 2023
Abstract The immune system is a central component of organismic function in humans. This paper addresses self‐organization of biological systems in relation to—and nested within—other biological systems in pregnancy. Pregnancy constitutes a fundamental state for human embodiment and a key step in the evolution and conservation of our species. While not

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 ...

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.

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 ...

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.

Emotional Burden of Olfactory Dysfunction: A Psychological Cluster Analysis from a Tertiary Smell and Taste Clinic

International Forum of Allergy &Rhinology, EarlyView.
Key Points The emotional burden of olfactory dysfunction bears distinct psychological profiles. Objective olfactory dysfunction findings do not reliably reflect patients' emotional burden. Olfactory‐related quality of life assessment may identify patient risk of emotional distress.

Spectral tuning and after-effects in neural entrainment

Behavioral and Brain Functions
Neural entrainment has become a popular technique to non-invasively manipulate brain rhythms via external, periodic stimulation. However, there is still debate regarding its underlying mechanisms and effects on brain activity.

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.

Psychophysics Phenomenologized? Sensation and Decision in Visual Motion Perception

Phenomenology and Mind, 2016
Experimental phenomenology and psychophysics are two rather different approaches to the study of perception, and rely on first-person descriptions and third-person measurements of the percept, respectively.

Psychophysics of suppression [PDF]

Eye, 1996
In amblyopia the visual input from the amblyopic eye is suppressed. The difference in contrast sensitivity between the two eyes can lead to suppression of the amblyopic eye through dichoptic masking in anisometropic amblyopia and small angle strabismus. Binocular cells in the visual cortex may also be instrumental in bringing about suppression in small
