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.

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 ReportsThe 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 ...

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 ...

Complementarity in Psychophysics [PDF]
, 2016 Besides the application of the notion of complementarity to psychological and physical descriptions of the individual, this paper explores the possibility of defining complementary observables in the same phenomenal domain. Complementary emotional observables are defined from experimental data on experienced emotions reported by subjects who have been ...

Animal Models and Experimental Medicine, EarlyView.The graphical abstract shows how molecular biology research has shifted from using traditional animal models toward using methods that are more relevant to humans. It points out the main problems, differences between species, difficulty in reproducing results, moral issues, and lack of infrastructure that make translational accuracy harder to achieve ...

The functional role of spatial anisotropies in ensemble perception
BMC BiologyBackground 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.
