Article Abstract
Spasticity is a recognized motor dysfunction that frequently arises following a stroke and significantly impacts the quality of life of affected patients. It is characterized by involuntary muscle activation resulting from overexcitation of the stretch reflex. Currently, therapeutic options for post-stroke spasticity are limited, and the underlying pathological mechanisms remain inadequately understood. Evidence suggests that stretch reflex hyperactivity is attributable to a combination of factors, including abnormal supraspinal projections, imbalances within the intraspinal network, and peripheral muscle alterations. This review aimed to examine supraspinal projections, specifically addressing the imbalance between excitatory and inhibitory output signals within the neural network of the brain's motor control region, and to discuss the significant role of the associated nerve bundles in the disease's pathogenesis.

Background: Early identification of pathological α-synuclein deposition (αSynD) may improve understanding of Lewy body disorder (LBD) progression and enable timely disease-modifying treatments.
Objectives: We investigated αSynD using a seed amplification assay and assessed prodromal LBD symptoms in individuals with idiopathic olfactory dysfunction (iOD).
Methods: In this cross-sectional, case-control study, we included iOD participants and normosmic healthy controls (HC) aged 55 to 75 years without diagnoses of dementia with Lewy bodies, Parkinson's disease (PD), or other major neurological disorders.

Objectives: To investigate the effects of formulated granules of (TGY) on motor deficits in a mouse model of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced subacute Parkinson's disease (PD) and explore the possible molecular mechanisms.
Methods: Ninety C57BL/6 mice were randomized equally into 6 groups, including a control group, a PD model group, a NEC-1 (6.5 mg/kg) treatment group, two TGY treatment groups at 5 and 2.

Aims: Decoding the motor intention by electroencephalography to control external devices is an effective method of helping spinal cord injury (SCI) patients to regain motor function. Still, SCI patients have much lower accuracy in the decoding of motor intentions compared to healthy individuals, which severely hampers the clinical application. However, the underlying neural mechanisms are still unknown.

Introduction: Due to its tonal and syllabic structures, Chinese speakers may encounter unique difficulties when learning native Western operatic techniques. These challenges are particularly evident in balancing pitch control, subglottic pressure, and vowel production. The present study examines how native language influences vocal performance, using the Italian art song Caro mio ben as a test piece for singers from different language backgrounds.
