Old Brain, New Tricks

The tongue is the one of the most sensitive areas in the body. When the tongue feels something, it is sent to the sensory cortex on either the left or right hemisphere depending on which side of the tongue the feeling is coming from. However to get to the brain, it travels from the tongue to the spinal cord via the sensory neurons. The sensory neurons travel from the spinal cord tothe thalamus. From there, the sensory neurons would relay to the messages to the interneurons, which are sent to the frontal lobes where the sensory cortex is located. After this, the message would be sent to the occipatal lobe where the eyesight is located. Once the occipatal lobe receives the message, the individual using this apparatus is able to see.
