Motion detection

Neurons in the mouse postrhinal cortex receive visual inputs from the superior colliculus and respond to visual motion independently of the primary visual cortex.

Single-unit recording in primate cortical area MT shows surprising sensitivity to depth defined by dynamical perspective cues. Depth might then be computed through recurrent circuits involving signals downstream of MT.

Neurons in cortical area MT have a crucial role in representing motion in depth.

Two new studies reveal a wiring plan that enables motion discrimination in the fly's visual system.

In both fruitflies and vertebrates, signals from photoreceptor cells are immediately split into two opposing channels in the downstream neurons. This might facilitate the computation of visual motion. See Letter p.300

A population of neurons in the somatosensory cortex responds specifically to the direction of a moving tactile stimulus.
