Fig. 1 Experimental evidence in support of a gradual accumulation of evidence in LIP. (A) LIP neurons ramp, on average, during an RT task. Michael N. Shadlen et al. Science 2016;351:1406 Published by AAAS

Fig. 2 Behavioral integration times are difficult to determine from the analyzed data set but are certainly shorter than the full 500- to 1000-ms viewing durations. Michael N. Shadlen et al. Science 2016;351:1406 Published by AAAS
