WebJan 11, 2016 · Here, we show that internally maintaining a color stimulus in working memory (WM), rather than visually attending the stimulus in the external environment, produces an analogous pattern of inhibition for stimuli that are nearby in color space. WebWorking memory is the ability to hold information “in mind.” It acts as a workspace on which information can be held, manipulated, and then used to guide behavior. In this way, it plays a critical role in cognition, decoupling behavior from the immediate sensory world. However, the circuit mechanisms that support working memory remain unclear. progressive technology phone seattle
