Functionally Assessing the Age-Related Decline in the Detection Rate of Photons by Cone Photoreceptors

open access: yesFrontiers in Aging Neuroscience, 2021
Age-related decline in visual perception is usually attributed to optical factors of the eye and neural factors. However, the detection of light by cones converting light into neural signals is a crucial intermediate processing step of vision ...

The Importance of Spatial Visual Scene Parameters in Predicting Optimal Cone Sensitivities in Routinely Trichromatic Frugivorous Old-World Primates

open access: yesFrontiers in Computational Neuroscience, 2018
Computational models that predict the spectral sensitivities of primate cone photoreceptors have focussed only on the spectral, not spatial, dimensions.

Synaptic Remodeling in the Cone Pathway After Early Postnatal Horizontal Cell Ablation

open access: yesFrontiers in Cellular Neuroscience, 2021
The first synapse of the visual pathway is formed by photoreceptors, horizontal cells and bipolar cells. While ON bipolar cells invaginate into the photoreceptor terminal and form synaptic triads together with invaginating horizontal cell processes, OFF ...

A Circadian Clock in the Retina Regulates Rod-Cone Gap Junction Coupling and Neuronal Light Responses via Activation of Adenosine A2A Receptors

open access: yesFrontiers in Cellular Neuroscience, 2021
Adenosine, a major neuromodulator in the central nervous system (CNS), is involved in a variety of regulatory functions such as the sleep/wake cycle.

The Homogenization Cone: Polar Cone and Projection

open access: yesSet-Valued and Variational Analysis, 2023
Let $C$ be a closed convex subset of a real Hilbert space containing the origin, and assume that $K$ is the homogenization cone of $C$, i.e., the smallest closed convex cone containing $C \times \{1\}$. Homogenization cones play an important role in optimization as they include, for instance, the second-order/Lorentz/"ice cream" cone.

Volatiles of All Native Juniperus Species Growing in Greece—Antimicrobial Properties

open access: yesFoods, 2023
Juniper (Juniperus L., Cupressaceae Bartlett) trees are of high commercial value, as their essential oils are widely applied in the food and cosmetic industries due to their bioactivities. The genus Juniperus comprises eight species in Greece, and in the
