Temporal vision: measures, mechanisms and meaning
Open accessAbstract
Time is largely a hidden variable in vision. It is the condition for seeing interesting things such as spatial forms and patterns, colours and movements in the external world, and yet is not meant to be noticed in itself. Temporal aspects of visual processing have received comparatively little attention in research. Temporal properties have been made explicit mainly in measurements of resolution and integration in simple tasks such as detection of spatially homogeneous flicker or light pulses of varying duration. Only through a mechanistic understanding of their basis in retinal photoreceptors and circuits can such measures guide modelling of natural vision in different species and illuminate functional and evolutionary trade-offs. Temporal vision research would benefit from bridging traditions that speak different languages. Towards that goal, I here review studies from the fields of human psychophysics, retinal physiology and neuroethology, with a focus on fundamental constraints set by early vision.

When LED irradiance was reduced, there was an intensity-dependent decrease in the magnitude of the dLight1 peak and an increase in the response latency.
“When LED irradiance was reduced, we observed an intensity-dependent decrease in the magnitude of the dLight1 peak and an increase in the response latency (Figure 2E–F), consistent with Bloch’s law of temporal summation in mammalian photoreceptors (Scharnowski et al., 2007; Donner, 2021).”
From Ventral striatum dopamine release encodes unique properties of visual stimuli in mice (2023) · cites this paper as Donner, 2021
The sections on response latencies and photoreceptor responses report that lower light intensity is associated with longer latency and that response amplitude scales with intensity in the linear range. The section on reading the rising phase discusses Bloch’s temporal-summation model but cautions that its sharp integration window applies only to the task used to measure it. Donner does not report the citing authors’ dLight1 measurements or establish that their peak-and-latency pattern follows Bloch’s law. (LLM, conf=0.82)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
