Impact of visual callosal pathway is dependent upon ipsilateral thalamus

open access: yesNature Communications, 2020
The visual callosal pathway reciprocally connects mammalian visual cortices and is proposed to facilitate activation of binocular neurons. Here, the authors show that this pathway facilitates responses in both monocular and binocular neurons but these ...

Functional Diversity of Neotropical Aquatic Hyphomycetes: Insights Into Environmental Drivers

open access: yesBiotropica, Volume 57, Issue 6, November 2025.
Subtropical streams host diverse hyphomycete assemblages than tropical one's. Larger saprotrophs with diverse conidia shapes dominate in subtropical areas. Cold and oxygenated waters have a positive effect on functional diversity. Poor litter in tropical favored the dominance of wood saprotrophs and endophytes.

Progressive Changes Between Thalamic Nuclei and Cortical Networks Across Stimulus–Response Learning

open access: yesHuman Brain Mapping, Volume 46, Issue 15, October 15, 2025.
We analysed functional magnetic resonance imaging (fMRI) data from a stimulus–response learning study to investigate functional connectivity changes across learning between thalamic nuclei with cortical networks and subcortical structures within healthy subjects.

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.

Functional modulation of primary visual cortex by the superior colliculus in the mouse

open access: yesNature Communications, 2018
The role of the superior colliculus (SC) in modulating V1 cortical activity is not clear. Here, the authors demonstrate the functional role of SC in modulating V1 responses through an excitatory pathway via the dorsal lateral geniculate nucleus.

A rare case of facial nerve schwannoma masked by a concomitant temporomandibular disorder pain

open access: yesInterdisciplinary Neurosurgery, 2018
Facial nerve schwannoma (FNS) is an uncommon benign tumor that arises from the Schwann cells of the facial nerve (FN). Although rare, this is the most frequent type of FN tumor, potentially affecting any segment of the nerve.
