Bounded Integration in Parietal Cortex Underlies Decisions Even When Viewing Duration Is Dictated by the Environment
Open accessAbstract
Decisions about sensory stimuli are often based on an accumulation of evidence in time. When subjects control stimulus duration, the decision terminates when the accumulated evidence reaches a criterion level. Under many natural circumstances and in many laboratory settings, the environment, rather than the subject, controls the stimulus duration. In these settings, it is generally assumed that subjects commit to a choice at the end of the stimulus stream. Indeed, failure to benefit from the full stream of information is interpreted as a sign of imperfect accumulation or memory leak. Contrary to these assumptions, we show that monkeys performing a direction discrimination task commit to a choice when the accumulated evidence reaches a threshold level (or bound), sometimes long before the end of stimulus. This bounded accumulation of evidence is reflected in the activity of neurons in the lateral intraparietal cortex. Thus, the readout of visual cortex embraces a termination rule to limit processing even when potentially useful information is available.

TL;DR
Monkeys performing a fixed-duration motion discrimination task committed to a choice when accumulated evidence reached a bound, sometimes well before stimulus offset, so late information was ignored rather than leaked. LIP activity reflected this bounded accumulation and predicted response times on short no-delay trials.
Key findings
- Behavioral accuracy improved with longer viewing duration but saturated; discrimination thresholds deviated from perfect square-root-of-time accumulation after ~420 ms (transition at n=15, durations 403–443 ms). A bounded-accumulator model fit better than a leaky-accumulator model (BIC 59.5; Bayes factor 8.35 × 10^12).
- Weak 3.2% coherence motion pulses biased choices overall by 1.3 ± 0.1% coherence (p < 10^-8), but in trials >700 ms, late pulses had no significant effect (third quartile: 0.2 ± 0.4%, p = 0.26; fourth quartile: −0.1 ± 0.4%, p = 0.63), while early pulses did (p = 0.018).
- In 51 LIP neurons, decision-related activity began ~207 ± 13 ms after motion onset, and mean responses reached a common criterion at 257 ± 9 ms. For short (<200 ms) no-delay trials, neural buildup rate was larger for fast responses (slope change, 48.7 ± 21.3 spikes/s²; p = 0.02), but this difference was absent in delay and long-duration trials.
- Bound-crossing time estimated from single-trial LIP activity correlated with RT on short no-delay trials (r = 0.16; p = 1.4 × 10^-4) and was reduced by inserting a delay (p = 0.0005). Error trials showed the same pattern: faster errors had larger buildup rates for short no-delay trials (59.4 ± 31.2 spikes/s²; p = 0.05).
Methods
- Two male rhesus monkeys performed a direction discrimination task with dynamic random dots; coherence was 0, 6.4, 12.8, 25.6, or 51.2%, and stimulus duration was randomly sampled from 80–1500 ms. The Go signal either coincided with motion offset or followed a 500–1000 ms delay. Data included 51 LIP neurons, 42,647 physiology-plus-psychophysics trials, and 60,921 additional psychophysics trials.
- A motion-pulse experiment in one monkey added a 200 ms, 3.2% coherence pulse at random times on every trial (18,017 trials; durations 280–1500 ms). Analyses used psychometric fits, bilinear threshold fitting, motion-energy filters, leaky- versus bounded-accumulator model comparison, logistic regression for pulse bias, neural PSTHs, input-variance estimation, and regression of neural buildup/bound-crossing times against RT.
Limitations
- The paper states that the actual bound level is unknown, bound-crossing times are noisy single-neuron estimates, and trial-by-trial neural–RT correlations are weak with slopes <1; RT is also limited by motor preparation and Go-signal detection. It notes that error trials for long durations were too few for similar analysis, and the pulse experiment used only one monkey.
- Evident from the text: the main LIP findings are correlational, with no causal manipulation in this paper (though the authors cite prior microstimulation work); the sample is limited to two monkeys and 51 LIP neurons, and the short/long duration cutoffs are somewhat arbitrary, though the paper says results do not rest critically on that choice.

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.
A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
