2-Minute Neuroscience: Touch and the Dorsal Columns-Medial Lemniscus

[2:01]

In my 2-Minute Neuroscience videos I simplistically explain neuroscience topics in 2 minutes or less. In this video, I discuss touch and the dorsal columns-medial lemniscus pathway. I describe the pathway somatosensory information takes from cutaneous receptors in the skin to the spinal cord and into either the fasciculus gracilis or fasciculus cuneatus. Then I follow the pathway through the medulla, to the ventral posterolateral nucles of the thalamus, and on to the somatosensory cortex. I also briefly describe the somatotopic arrangment of the somatosensory cortex.
