To assess the diagnostic efficiency and direct costs of electrophysiologic tests, times and clinical data (admittance, diagnosis, final diagnosis and clinical reports) of 144 patients were recorded and statistically analyzed. Capital outlay on equipment and personnel costs were also evaluated to determine the economic impact of the tests. Electrophysiologic tests were found to play an important role in diagnosis and choice of therapy. It is important to improve collaboration between the referring ophthalmologist and the electrophysiology staff to inform patients better and to optimize the cost-benefit standards of the service. The current reimbursement by the Regional Public Health Service underestimates the costs of electrophysiologic tests.

Usher syndrome is a rare autosomal recessive genetic disorder that primarily affects both vision and hearing, manifesting as sensorineural hearing loss and progressive vision loss caused by retinitis pigmentosa. The pathogenesis of retinal degeneration in Usher syndrome is still largely unknown. In this study, a novel Ush2a knockout mouse model was successfully constructed using CRISPR/Cas9 technology.

Objective: The aim of the present study is to examine the relationship between EEG measures and functional recovery in right-hemisphere stroke patients.
Methods: Participants with stroke (PS) and neurologically unimpaired controls (UC) were enrolled. At enrolment, all participants were assessed for motor and cognitive functioning with specific scales (motricity index, trunk control test, Level of Cognitive Functioning, and Functional Independence Measure (FIM).

The organophosphorus pesticide chlormephos was tested for its potential peripheral neurotoxicity by analyzing the diphasic compound action potential (CAP) of sciatic nerves isolated from adult mice chronically exposed to a sub-lethal dose of this pesticide, compared with control age-matched animals being only exposed to the vehicle. No significant modification was detected between chlormephos-exposed and control groups in their nerve responsiveness to stimulus. Furthermore, similar values of CAP kinetic variables were obtained from the two mouse groups.

In this study, we present ECoGScope, a versatile neural interface platform designed to integrate multiple functions for advancing neural network research. ECoGScope combines an electrocorticography (ECoG) electrode array with a commercial microendoscope, enabling simultaneous recording of ECoG signals and fluorescence imaging. The electrode array, constructed from highly flexible and transparent polymers, ensures conformal contact with the brain surface, allowing unobstructed optical monitoring of neural activity alongside electrophysiological recordings.

Millions of patients and their caretakers live and deal with the devastating consequences of spinal cord injury (SCI) worldwide. Despite outstanding advances in the field to both understand and tackle these pathologies, a cure for SCI patients, with their peculiar characteristics, is still a mirage. One of the most promising therapeutic strategies to date for these patients involves the use of epidural electrical stimulation.
