161 patients with multiple sclerosis were observed according to C. M. Poser's scale. The diagnosis was definite in 73.9% of cases, probable--in 14.9% and doubtful in 11.2% of patients. The diagnostic significance of magnetic resonance tomography (MRT) was estimated as well as of visual evoked potentials (VEPs), mid-latency auditory evoked potentials (MAEPs), viscocontrastoperimetry and pallesthesiometry (vibratory sensation). MRT revealed alterations in 80.3% of 71 cases (97.5% at definite diagnosis). The results of investigation of evoked potentials differed from normal values: VEPs in 100%, MAEPs in 72.6% of 26 patients observed. Visocontrastoperimetry revealed disorders in 75,2% of 113 cases, pallesthesiometry in toes--in 100%, in fingers--in 68.9% of 116 patients observed.

Introduction: Color vision deficiency (CVD), a common visual impairment, affects individuals' ability to differentiate between various colors due to malfunctioning or absent color photoreceptors in the retina. Currently available diagnostic tests require a behavioral response, rendering them unsuitable for individuals with limited physical and communication abilities, such as those with locked-in syndrome. This study introduces a novel, non-invasive method that employs brain signals, specifically Steady-State Visually Evoked Potentials (SSVEPs), along with Ishihara plates to diagnose CVD.

Background: Prone transpsoas lumbar interbody fusion (PTP) is a newer technique to treat various spinal disc pathologies. PTP is a variation of lateral lumbar interbody fusion (LLIF) that is performed with the patient prone rather than in the lateral decubitus position. This approach offers similar benefits of lateral spinal surgery, which include less blood loss, shorter hospital stay, and quicker recovery compared with traditional open spine surgery.

Subjective confidence and uncertainty are closely related to cognition and behavior. However, direct evidence that subjective confidence controls attention allocation is lacking. This study aimed to clarify whether subjective confidence could be involved in controlling attention allocation and intensity.

Objective: Evaluating the potential role of neuromuscular ultrasonography (NMUS) in assessing optic nerve affection in patients with systemic lupus erythematosus (SLE), compared with healthy controls and other conventional strategies in diagnosing optic neuropathy.
Methods: We conducted an observational cross-sectional study comparing patients with SLE and a healthy group. We measured the optic nerve diameter (OND) and optic nerve sheath diameter (ONSD) and calculated the OND/ONSD ratio and side-to-side difference.

Blood flow restriction (BFR) combined with low work rate exercise can enhance muscular and cardiovascular fitness. However, whether neural mechanisms mediate these enhancements remains unknown. This study examined changes in corticospinal excitability and motor cortical inhibition following arm cycle ergometry with and without BFR.
