Thus, the two areas of the central nervous system being most active during magnetic compass orientation are part of an ascending visual processing stream, the thalamofugal pathway.

Thus, the identification of what sensory system (s) is active during magnetic compass orientation, provides a way to recognize the sensory quality utilized during that specific behavior.

We furthermore suggested that Cluster N is likely to process such light - mediated magnetic compass responses, based on the fact that Cluster N is the only known forebrain area that is highly active during magnetic compass orientation, and on the theoretical model [7] on magnetic field modulation of the light sensitivity of specialized receptor molecules in the retina of the birds, [for detailed arguments see 13], [14].

By combining neuronal tracing with behavioral experiments leading to sensory - driven gene expression of the neuronal activity marker ZENK during magnetic compass orientation, we demonstrate a functional neuronal connection between the retinal neurons and Cluster N via the visual thalamus.
