Information transmission in oscillatory neural activity

open access: yes, 2008
Periodic neural activity not locked to the stimulus or to motor responses is usually ignored. Here, we present new tools for modeling and quantifying the information transmission based on periodic neural activity that occurs with quasi-random phase ...

Developmental disorders of vision [PDF]

open access: yes, 2003
This review of developmental disorders of vision focuses on a few of the many disorders that disrupt visual development. Given the enormity of the human visual system in the primate brain and complexity of visual development, however, there are likely ...

Complementarity of BOLD and ADC‐fMRI in Mapping Brain Visual Processing in the Rat

open access: yesNMR in Biomedicine, Volume 39, Issue 3, March 2026.
BOLD‐fMRI and ADC‐fMRI were acquired at 9.4 and 14 T during visual stimulation with variable frequency. BOLD‐fMRI showed robust positive/negative responses but depended on regional vascularization patterns. ADC‐fMRI was able to detect neural activity independently from vascular effects at 9.4 T.

NON-GENICULATE CORALLINE ALGAE (CORALLINALES, RHODOPHYTA) FROM THE LOWER OLIGOCENE OF POLJŠICA PRI PODNARTU (NORTHERN SLOVENIA)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2009
Despite their increasing importance in sedimentology and palaeoecology, non-geniculate coralline algae remain virtually overlooked in Slovenia. Though these plants are present or even abundant in the Cretaceous and Cainozoic strata, they have never been ...

Spatial heterogeneity in microglia‐complement crosstalk: Implications for synaptic pruning in Alzheimer's disease

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract Alzheimer's disease (AD) is a neurodegenerative disorder characterized by synaptic loss, as a key pathological feature in its early stages. Recent studies have highlighted the central role of microglia–complement interactions in synaptic pruning.

Facial Nerve Paresis in Ramsay Hunt Syndrome

open access: yesMajalah Kedokteran Andalas
Introduction: Ramsay Hunt syndrome (SRH) is known as otic herpes zoster or geniculate ganglion herpes zoster, which is a late complication of Varicella-Zoster Virus (VZV) infection, which causes inflammation of the geniculate ganglion of cranial nerve ...

Macroid Formation in Salmacina stellaebayensis n. sp. From Mauritania's Baie de l'Étoile With New Insights on Mitogenome Evolution in Serpulidae (Annelida)

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We describe Salmacina stellaebayensis n. sp. from Mauritania's Baie de l'Étoile and provide the first complete mitochondrial genome for the genus Salmacina. The species forms distinctive macroid colonies in Cymodocea nodosa seagrass meadows, offering new insights into serpulid life history and habitat specialization.

Emergent Orientation Selectivity from Random Networks in Mouse Visual Cortex [PDF]

open access: yes, 2018
The connectivity principles underlying the emergence of orientation selectivity in primary visual cortex (V1) of mammals lacking an orientation map (such as rodents and lagomorphs) are poorly understood.

Tinnitus and hyperacusis involve hyperactivity and enhanced connectivity in auditory-limbic-arousal-cerebellar network

open access: yeseLife, 2015
Hearing loss often triggers an inescapable buzz (tinnitus) and causes everyday sounds to become intolerably loud (hyperacusis), but exactly where and how this occurs in the brain is unknown.
