Article Abstract
Due to its ability to modulate neuronal activity, electrical stimulation of the eye may be a promising therapy for preserving or restoring vision. To investigate how electrical currents can influence visual function, Transcorneal Electrical Stimulation (TES) was tested on both female and male C57BL/6 mice to evaluate its neuromodulatory effect from the retina to the cerebral cortex through visual evoked potential (VEP) and electroretinogram (ERG) recording. VEP or ERG was acquired before (baseline), immediately (t0), after 5 min (t5), and 10 min (t10) of sham (i.e., no stimulation) or TES applied on the eye of anesthetized C57BL/6 mice. Notably, TES affected neuronal activity in the visual pathway since a significant increase in VEP and ERG amplitude was detected and persisted 10 min after TES. The amplitude increase induced by TES could underlie an enhancement of neuronal excitability that may ameliorate retinal-genicular-cortical function in diseases involving the visual system.

Innovative technology allows for personalization of stimulation frequency in dual-site deep brain stimulation (DBS), offering promise for challenging symptoms in advanced Parkinson's disease (PD), particularly freezing of gait (FoG). Early results suggest that combining standard subthalamic nucleus (STN) stimulation with substantia nigra pars reticulata (SNr) stimulation may improve FoG outcomes. However, patient response and the optimal SNr stimulation frequency vary.

Background: Currently, most researchers apply pollen extracts or -suspensions to assess the effects of pollen exposure on airway epithelia. How respiratory epithelia respond to pollen aerosols is not well studied because standardised methods to aerosolize pollen were not available until recently.
Aim Of Study: To develop and test a near-natural exposure model for pollen grains based on differentiated human nasal epithelial cells and a novel particle aerosoliser.

Clinical trials of the photovoltaic subretinal prosthesis PRIMA demonstrated feasibility of prosthetic central vision with resolution matching its 100 μm pixel width. To improve prosthetic acuity further, pixel size should be decreased. However, there are multiple challenges, one of which is related to accommodating a compact shunt resistor within each pixel that discharges the electrodes between stimulation pulses and helps increase the contrast of the electric field pattern.

Transcranial temporal interference stimulation (tTIS) has recently emerged as a non-invasive neuromodulation method aimed at reaching deeper brain regions than conventional techniques. However, many questions about its effects remain, requiring further experimental studies. This review consolidates the experimental literature on tTIS's effects in the human brain, clarifies existing evidence, identifies knowledge gaps, and proposes future research directions to evaluate its potential.
