Which part of the brain directs incoming sensory messages so that you can see, hear, and smell?

The Thalamus is the part of brain directs incoming sensory messages.

Explanation:

Thalamus acts as a train hub for incoming sensory messages for vision, hearing and smell. Input from the retina, which is delivered to the brain, receives by the thalamus. The Neuron of the primary auditory pathway connects the auditory cortex and decoded the message. The only sensory system not relay on the thalamus is related to smell, however, co-relating and higher level processing with memories will go through the thalamus.

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.
