Surgical Outcomes Comparison of Spontaneous Middle Cranial Fossa Cerebrospinal Fluid Leaks: Systematic Review and Meta‐analysis

open access: yesOtolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Spontaneous cerebrospinal fluid (sCSF) leaks of lateral skull base have little consensus on optimal management. We synthesized and evaluated current literature via systematic and meta‐analysis to compare the success rates and complications of the different surgical techniques for middle cranial fossa (MCF) sCSF leak repair.

Modeling the Possible Influences of Eye Movements on the Refinement of Cortical Direction Selectivity [PDF]

open access: yes, 2004
The second-order statistics of neural activity was examined in a model of the cat LGN and V1 during free-viewing of natural images. In the model, the specific patterns of thalamocortical activity required for a Bebbian maturation of direction-selective ...

Three and Four Courses of Radiation for Children with Recurrent Diffuse Intrinsic Pontine Glioma

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Re‐irradiation (RT2) for children with diffuse intrinsic pontine glioma (DIPG) is increasingly used upon recurrence; however, limited data are available for evaluating additional courses of radiotherapy (RT) for DIPG. The purpose of this case series was to report our institutional experience in treating patients with recurrent DIPG ...

The projection of the retina in the lateral geniculate body [PDF]

open access: yesProceedings of the Royal Society of London. Series B, Containing Papers of a Biological Character, 1934
The question of a localization of some degree in the lateral geniculate body in regard to the termination of fibres from different parts of the retina is no longer a matter of discussion. The Classical work of Henschen and Winkler in support of this conception has been amply substantiated by later investigators.

Functional representation of vision within the mind: A visual consciousness model based in 3D default space [PDF]

open access: yes, 2015
The human eyes and brain, which have finite boundaries, create a ‘‘virtual’’ space within our central nervous system that interprets and perceives a space that appears boundless and infinite.

Characterisation of localised pigment accumulation in brains of eastern grey kangaroos (Macropus giganteus) after clinical disease due to chronic Phalaris species toxicosis

open access: yesAustralian Veterinary Journal, EarlyView.
A progressive tremorgenic syndrome characterised by ataxia and head nodding is well documented in sheep and cattle affected by chronic Phalaris toxicosis (CPT), and is increasingly documented in the eastern grey kangaroo {(EGK), Macropus giganteus} in southeastern Australia.

Psychophysical evidence for two routes to suppression before binocular summation of signals in human vision [PDF]

open access: yes, 2007
Visual mechanisms in primary visual cortex are suppressed by the superposition of gratings perpendicular to their preferred orientations. A clear picture of this process is needed to (i) inform functional architecture of image-processing models, (ii ...

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.

Spindle oscillations are generated in the dorsal thalamus and modulated by the thalamic reticular nucleus [PDF]

open access: yes, 2008
Spindle waves occur during the early stage of slow wave sleep and are thought to arise in the thalamic reticular nucleus (TRN), causing inhibitory postsynaptic potential spindle-like oscillations in the dorsal thalamus that are propagated to the cortex ...

The futuristic manifolds of REM sleep

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Since one of its first descriptions 70 years ago, rapid eye movement sleep has continually inspired and excited new generations of sleep researchers. Despite significant advancements in understanding its neurocircuitry, underlying mechanisms and microstates, many questions regarding its function, especially beyond the early neurodevelopment ...
