A new species of Paratanais Dana, 1852 (Crustacea, Peracarida, Tanaidacea, Paratanaidae) from Puerto Rico, northwestern Atlantic

open access: yesZooKeys, 2014
Paratanais rosadi sp. n. described from Puerto Rican coastal waters represents the first species of the genus from the northwestern Atlantic. It is distinguished from the other Paratanais species by a combination of characters, including article-2 of the

Variation of connectivity across exemplar sensory and associative thalamocortical loops in the mouse

open access: yeseLife, 2020
The thalamus engages in sensation, action, and cognition, but the structure underlying these functions is poorly understood. Thalamic innervation of associative cortex targets several interneuron types, modulating dynamics and influencing plasticity.

Patterns of phosphorylated tau accumulation in a spectrum of acquired and developmental brain lesions associated with refractory epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective Phosphorylated tau (pTau) has been reported in surgical resections in refractory epilepsy. It is unclear whether this is activity‐driven physiological pTau or signifies the advent of neurodegenerative cascades, relevant to memory decline.

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 ...

Temporal Dynamics of Binocular Disparity Processing with Corticogeniculate Interactions [PDF]

open access: yes, 1999
A neural model is developed to probe how corticogeniculate feedback may contribute to the dynamics of binocular vision. Feedforward and feedback interactions among retinal, lateral geniculate, and cortical simple and complex cells are used to simulate ...

Functional evidence for cone-specific connectivity in the human retina [PDF]

open access: yes, 2009
NoPhysiological studies of colour vision have not yet resolved the controversial issue of how chromatic opponency is constructed at a neuronal level. Two competing theories, the cone-selective hypothesis and the random-wiring hypothesis, are currently ...

Phylogenetics and reticulation among koelerioid clades, part I: Contraction of Trisetum, expansion of Acrospelion, Graphephorum, and Tzveleviochloa; Graciliotrisetum gen. nov. and resurrection of Aegialina (Poaceae, Pooideae, Poeae, Aveninae)

open access: yesJournal of Systematics and Evolution, Volume 63, Issue 3, Page 629-655, May 2025.
Phylogenetic analysis of Koeleriinae clades A and B yielded mostly congruent topologies in nuclear and plastid trees. However, several lineages resolved in strikingly incongruent positions in trees from different data sets, suggesting a reticulate origin for these taxa.

A Pseudoaneurysm of the Inferior Lateral Geniculate Artery Following Total Knee Arthroplasty

open access: yesArthroplasty Today, 2022
Vascular complications after total knee arthroplasty are rare. We present a case of an inferior lateral geniculate artery pseudoaneurysm which became symptomatic 10 days after total knee arthroplasty in a patient with a cardiac comorbidity and using ...

Temporal Dynamics of Binocular Display Processing with Corticogeniculate Interactions [PDF]

open access: yes, 1995
A neural model of binocular vision is developed to simulate psychophysical and neurobiological data concerning the dynamics of binocular disparity processing.

Dendritic and axonal targeting patterns of a genetically-specified class of retinal ganglion cells that participate in image-forming circuits. [PDF]

open access: yes, 2014
BackgroundThere are numerous functional types of retinal ganglion cells (RGCs), each participating in circuits that encode a specific aspect of the visual scene.
