Facilitative integration of local motion signals in the peripheral visual field observed in monkey ocular following responses

► We explored how local motion signals in the peripheral visual field are integrated. ► We recorded ocular following responses (OFRs) to various moving gratings. ► The OFRs were tuned to lower spatial frequency as stimulus size increased. ► The OFRs to two gratings were larger than the sum of the responses to the components. ► A mechanism, weak signals are integrated into an effective ensemble, may underlie.
