Retinal Prostheses and Artificial Vision

open access: yesTürk Oftalmoloji Dergisi, 2019
In outer retinal degenerative diseases such as retinitis pigmentosa, choroideremia, and geographic atrophy, 30% of the ganglion cell layer in the macula remains intact.

Where Are the fMRI Correlates of Phosphene Perception?

open access: yesFrontiers in Neuroscience, 2018
Pulses of transcranial magnetic stimulation (TMS) over occipital cortex can induce transient visual percepts called phosphenes. Phosphenes are an interesting stimulus for the study of the human visual system, constituting conscious percepts without ...

Test–retest variability of the full‐field stimulus test in patients with retinitis pigmentosa: REPEAT Study Report No. 4

open access: yesActa Ophthalmologica, Volume 104, Issue 1, Page 89-97, February 2026.
Abstract Purpose To evaluate test–retest variability (TRV) of the full‐field stimulus test (FST) in patients with retinitis pigmentosa (RP) and poor best‐corrected visual acuity (BCVA; ≤20/50 Snellen; ≥0.40 logMAR), and to assess the reliability of FST as a clinical endpoint in future RP trials.

Why Temporal Inference Stimulation May Fail in the Human Brain: A Pilot Research Study

open access: yesBiomedicines, 2023
Temporal interference stimulation (TIS) aims at targeting deep brain areas during transcranial electrical alternating current stimulation (tACS) by generating interference fields at depth.

Theta Transcranial Alternating Current Stimulation Over the Dorsomedial Prefrontal Cortex Does Not Enhance Long‐Term Memory

open access: yesEuropean Journal of Neuroscience, Volume 63, Issue 3, February 2026.
We tested whether 4‐Hz transcranial alternating current stimulation over the dorsomedial prefrontal cortex enhances long‐term memory retrieval. Thirty‐three participants encoded images of faces, objects and scenes varying in memorability and completed a recognition test during stimulation.

On the “blindness” of blindsight: What is the evidence for phenomenal awareness in the absence of primary visual cortex (V1)? [PDF]

open access: yes, 2019
Blindsight has been central to theories of phenomenal awareness; that a lesion to primary visual cortex (V1) abolishes all phenomenal awareness while unconscious visual functions can remain has led to the views that this region plays in generating visual

Continuous Theta Burst to Supplementary Motor Area Modulates Groove

open access: yesAnnals of the New York Academy of Sciences, Volume 1556, Issue 1, February 2026.
ABSTRACT The pleasurable urge to move to music (“groove”) has been shown to be greatest for moderately complex musical rhythms. This is thought to occur because temporal predictions from the motor system reinforce our perception of the beat when there is a balance between expectation and surprise.

Novel pyridine-based Pd(II)-complex for efficient Suzuki coupling of aryl halides under microwaves irradiation in water

open access: yesChemistry Central Journal, 2017
Suzuki C–C cross-coupling of aryl halides with aryl boronic acids using new phosphene-free palladium complexes as precatalysts was investigated.

Individual differences in sensory sensitivity: a synthesising framework and evidence from normal variation and developmental conditions [PDF]

open access: yes, 2019
For some people, simple sensory stimuli (e.g., noises, patterns) may reliably evoke intense and aversive reactions. This is common in certain clinical groups (e.g., autism) and varies greatly in the neurotypical population.
