 A different explanation ties perceptual consciousness to processing independent of the workspace, with focus on recurrent activity in sensory areas. This approach emphasizes properties of first-order neural representation as explaining consciousness. Victor Lamme (2006, 2010) argues that recurrent processing is necessary and sufficient for consciousness. Recurrent processing occurs where sensory systems are highly interconnected and involve feedforward and feedback connections. For example, forward connections from primary visual area V1, the first cortical visual area, carry information to higher-level processing areas, and the initial registration of visual information involves a forward sweep of processing. At the same time, there are many feedback connections linking visual areas (Felleman &amp; Van Essen 1991), and later in processing, these connections are activated yielding dynamic activity within the visual system.
