It is unknown how external noise interacts with neural noise in producing an SR\u2010like phenomenon and whether this interaction results in a modulation of either network efficiency or the efficiency of single neurons. Using random dot motion stimuli and noninvasive brain stimulation, we attempted to unveil the specific mechanism of action of the SR\u2010like phenomenon in motion perception, if present. We aimed to determine whether signal integration efficiency changes with external noise (random dot numerosity) and how electrical transcranial random noise stimulation (tRNS) can affect the peak performance. The participants performed a coherent motion detection task in which the random dot numerosity varied, whereas the signal\u2010to\u2010noise ratio (SNR) remained constant. We applied placebo or tRNS with an amplitude of either 1 or 2\u00a0mA during task execution. We found peaks in participants' performance both in the case of placebo stimulation and in the case of 1\u2010mA tRNS. In the latter case (i.e., with an additional noise source), the peak emerged at lower random dot numerosity levels than when no additional noise was added (placebo). No clear peak was observed with 2\u2010mA tRNS. An equivalent noise (EN) analysis confirmed that SR arises from a modulation of the network efficiency underlying motion signal integration. These results indicate a joint contribution of external and neural noise (modulated by tRNS) in eliciting an SR\u2010like phenomenon.<\/jats:p>","DOI":"10.1111\/ejn.15965","type":"journal-article","created":{"date-parts":[[2023,3,16]],"date-time":"2023-03-16T00:24:46Z","timestamp":1678926286000},"page":"2097-2111","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Noise
