Niche sharing reflects a poorly understood biodiversity phenomenon [PDF]

open access: yes, 2009
Eucalyptus spp. are susceptible to a large number of foliar pathogens, some of which can cause serious defoliation and die-back. In this study, a single leaf spot on a Eucalyptus leaf collected in Madagascar revealed an unusual association of microfungi ...

AN ANALYSIS OF EXTRACELLULAR POTENTIALS FROM SINGLE NEURONS IN THE LATERAL GENICULATE NUCLEUS OF THE CAT

open access: yesThe Journal of General Physiology, 1958
The lateral geniculate nucleus of the cat was explored with micropipettes having submicroscopic tips. The only reliably recorded intracellular activity was from axons.

Gating Input to Visual Cortex by Feedback to LGN [PDF]

open access: yes, 1998
Anatomical studies have documented massive back-projections from higher to lower visual cortices and to the lateral geniculate nucleus (LGN). The large number of synapses from these sources suggest that they should have a profound influence on the ...

Altered functional connectivity in lesional peduncular hallucinosis with REM sleep behavior disorder [PDF]

open access: yes, 2015
Brainstem lesions causing peduncular hallucinosis (PH) produce vivid visual hallucinations occasionally accompanied by sleep disorders. Overlapping brainstem regions modulate visual pathways and REM sleep functions via gating of thalamocortical networks.

The Current Situation and Development of Endoscopic Ear Surgery in China

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Endoscopic ear surgery has been widely performed in China since 2015 due to the development and rapid popularization of endoscopic technology. Due to the relative shortness of the auditory meatus, only a fixed endoscope is required in many cases, rather than a motion similar to a nasal endoscope, and uncontrollable bleeding is virtually non ...

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 ...

Looking back: corticothalamic feedback and early visual processing [PDF]

open access: yes, 2006
[Abstract] Although once regarded as a simple sensory relay on the way to the cortex, it is increasingly apparent that the thalamus has a role in the ongoing moment-by-moment processing of sensory input and in cognition.

Sleep neuroimaging: Review and future directions

open access: yesJournal of Sleep Research, EarlyView.
Summary Sleep research has evolved considerably since the first sleep electroencephalography recordings in the 1930s and the discovery of well‐distinguishable sleep stages in the 1950s. While electrophysiological recordings have been used to describe the sleeping brain in much detail, since the 1990s neuroimaging techniques have been applied to uncover

The BAsic NeuroCognitive Continuum (BANCC): Delineation of dimensional and categorical features for etiological and treatment investigations of idiopathic psychosis

open access: yesPsychiatry and Clinical Neurosciences, EarlyView.
Aim Cognition varies across people with psychosis, including within a specific diagnosis. An important issue is identifying psychosis‐specific neuro‐cognitive dysfunctions. We addressed this issue by studying patterns of relationships between cognition and multiple other measures in persons with psychosis, their first‐degree biological relatives, and ...
