The phrase "a lagging marker" is correct and usable in written English.
It can be used in contexts where you are discussing indicators or signs that reflect a delay in performance or trends, often in economics or statistics.
Example: "The unemployment rate is often considered a lagging marker of economic health, as it reflects conditions that have already occurred."
Alternatives: "a trailing indicator" or "a delayed signal".
For the gap stimulus the onset of the lagging marker elicited a similar pattern of oscillation with peak latency and amplitude comparable to the onset response.
In summary, we conclude that the early part of the 40-Hz activity, as observed in the onset and difference waveforms, is related to signaling the onset of leading and lagging marker in a specific thalamocortical loop.
An age-related increase in the time constant of the response to the leading marker would increase the degree to which a response to the initial marker masks the response to the lagging marker [17].
The difference waves for all stimulus types, age groups and both hemispheres showed a pattern of positive and negative deflections in the interval after onset of the lagging marker compared to the immediately preceding time interval indicating responses to the leading marker.
The time scales were adjusted so time zero corresponds to the onset of the lagging marker.
The effects on P1m were small because of the short time interval between onset of the leading and lagging marker.
This effect was evident for both the sound onset response and for the derived response to the onset of the lagging marker.
Multi-unit responses to the onset of the lagging marker recorded from the cat auditory cortex closely resembled behavioural threshold [11] suggesting that cortical function may be the limiting factor for gap detection performance.
An established model for the limits (i.e., thresholds) in gap detection posits that the sensation of the leading marker preceding the gap does not vanish immediately after it ends but rather decays with a certain time constant and interferes with the subsequent sensation related to the onset of the lagging marker [2].
Such a model based on auditory time constants limiting the registration of leading and lagging markers has received support from animal studies showing that neurons in the inferior colliculus responded preferentially to the onsets of the markers [9], [10].
