Hierarchical cortical gradients in somatosensory processing

NeuroImage, 2020
Sensory information is processed in the visual cortex in distinct streams of different anatomical and functional properties. A comparable organizational principle has also been proposed to underlie auditory processing. This raises the question of whether

Measurement of language laterality using functional transcranial Doppler ultrasound: a comparison of different tasks [version 1; referees: 2 approved]

Wellcome Open Research, 2018
Background: Relative blood flow in the two middle cerebral arteries can be measured using functional transcranial Doppler sonography (fTCD) to give an index of lateralisation as participants perform a specific task.

Heritability of language laterality assessed by functional transcranial Doppler ultrasound: a twin study [version 2; peer review: 1 approved, 2 approved with reservations]

Wellcome Open Research, 2020
Background: Prior studies have estimated heritability of around 0.25 for the trait of handedness, with studies of structural brain asymmetry giving estimates in a similar or lower range.

Handgrip strength asymmetry is associated with the risk of neurodegenerative disorders among Chinese older adults

Journal of Cachexia, Sarcopenia and Muscle, 2022
Background Neurodegenerative disorders, as the irreversible condition, have a long, silent preclinical period. Recognition of early physical signs of neurodegenerative disorders had important practical implications for identifying at‐risk population. The

The right visual field advantage and the optimal viewing position effect: On the relation between foveal and parafoveal word recognition [PDF]

, 1996
Recent developments on the optimal viewing position (OVP) effect suggest that it may be caused by the same factors that underlie the right visual field advantage in word recognition.

DELP Treatment on Vision and Retinal Microcirculation in Patients With Acute Ischemic Stroke: Report of Five Cases and Literature Review

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.

The face, beauty, and symmetry: Perceiving asymmetry in beautiful faces [PDF]

, 2005
The relationship between bilateral facial symmetry and beauty remains to be clarified. Here, straight head-on photographs of “beautiful” faces from the collections of professional modeling agencies were selected.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Brain laterality evaluated by F-18 fluorodeoxyglucose positron emission computed tomography in autism spectrum disorders

Frontiers in Molecular Neuroscience, 2022
Background and rationaleAutism spectrum disorder (ASD) is a neuropsychiatric disorder that has no curative treatment. Little is known about the brain laterality in patients with ASD. F-18 fluorodeoxyglucose positron emission computed tomography (F-18 FDG
