The “chapeau de gendarme” sign in focal epilepsy: A systematic review

open access: yesEpileptic Disorders, Volume 27, Issue 5, Page 867-882, October 2025.
Abstract The “chapeau de gendarme” sign, also known as “ictal pouting,” is a distinctive facial expression observed in focal epilepsy, characterized by a turned‐down mouth with symmetrical lip and chin contraction. This systematic review investigates its clinical relevance, anatomical origins, and diagnostic value, particularly in presurgical ...

Cavernous angioma of the cavernous sinus: imaging findings Angioma cavernoso do seio cavernoso: achados aos exames de imagem

open access: yesArquivos de Neuro-Psiquiatria, 2004
Cavernous angiomas (cavernomas) of the cavernous sinus are uncommon, with only scattered reports in literature. Unlike their parenchymatous counterparts, they are intensely enhancing para-sellar masses, iso/hypointense in T1- and hyperintense in T2 ...

Improving the Quality of Brain PET Images Using MR‐Guided PET Reconstruction Technique With Integrated PET/MR

open access: yesHuman Brain Mapping, Volume 46, Issue 11, 01 August 2025.
The PET list‐mode data was processed with OSEM algorithm and MR‐guided reconstruction (MRg) based on T1‐weighted MR images (TIWI). Several quantitative parameters were calculated to compare the image quality for conventional OSEM, OSEM_GF, and MRg reconstructions with varying parameters (θ = 0.5, 1, 2).

Incidence, Characteristics, and Risk Factors of Post‐Radiosurgery Headaches: A Prospective Observational Study

open access: yesCNS Neuroscience &Therapeutics, Volume 31, Issue 3, March 2025.
Based on prospective observations of the characteristics of post‐radiosurgery headache, supplementary diagnostic criteria have been proposed. Female gender, younger age, no prior craniocerebral surgery, and multiple lesions are identified as risk factors for the occurrence of post‐radiosurgery headache.

α4β2* nicotinic acetylcholine receptors drive human temporal glutamate/GABA balance toward inhibition

open access: yesThe Journal of Physiology, Volume 603, Issue 6, Page 1645-1662, 15 March 2025.
Abstract figure legend α4β2* nicotinic acetylcholine receptors (α4β2*nAChR) modulate the synaptic transmission in the temporal human neocortex, recorded from layer 5 pyramidal neurons. We describe a monosynaptic mechanism at the GABAergic synapses (left), in which the activation of the heteromeric nicotinic receptors, expressed on the presynaptic cell,

Peri‐ictal yawning: A potential lateralizing sign in temporal lobe epilepsy

open access: yesEpilepsia Open, Volume 10, Issue 1, Page 196-209, February 2025.
Abstract Objective The primary objective of this retrospective analysis was to evaluate the incidence and lateralization value of peri‐ictal yawning (PY) in people with temporal lobe epilepsy (TLE). PY has only occasionally been reported as a manifestation of focal epilepsy.
