We generally assume that two thalamic visual pathways – the parvocellular and magnocellular – relay monocular and orientation insensitive retinal signals to visual cortex. Here I describe work with Paul Martin where we have explored the functional properties of a neglected but evolutionarily ancient thalamic pathway – the koniocellular pathway. We find that this pathway includes neurons that are binocular, neurons that are tightly tuned for contour orientation, and neurons that integrate visual with non-sensory brain signals.
