Presenter: Camila Losada

Adapting our behavior to our environment depending on contextual demands involves large, distributed networks of cortical and subcortical areas. Prefrontal (PFC) and lateral intraparietal area (LIP) process both sensory and cognitive factors in very similar manner. However, their respective contributions to visual processing and cognitive control remain largely unclear. In this study, macaque monkeys performed a modified delay-match to sample task while we simultaneously recorded neuronal activity from V4, LIP and PFC. We show differential PFC/LIP dynamics: PFC exhibits successive encoding of different cognitive processes, while LIP shows more stable representations that integrate both sensory and cognitive signals.
