Special sensory neurons in sense organs that receive stimuli from the external environment.

In an insect, the sensory structure is located in the head, not the abdomen. Its sensory organs are its antennae, which allows it to smell and taste. In some insects, like cicadas, the sensory organs are in the abdomen because they lack the same antennae as other insects.
Cognitive resonance.

The sensory organs developed around the mouth in an attempt to help the creature eat - that being the primary reason for senses. Because all the sensory organs were concentrated around the mouth that was the beginnings of the head. So you see - the concentration of sensory organs was the reason for the head. There was no head to begin with. The head (and brain) developed because that was where all the sensory organs (and mouth) were. As for an advantage. It might be advantageous to have your sensory organs as high as possible. The reason for this is obvious for sight and sound. Smelling however would benefit more if it were located in the feet. Consider dogs and pigs. As soon as they start smelling they put their nose (and the rest of the head as well) to the ground. Feeling is not found concentrated in the head but is omni-localized.

The tongue is a boneless sensory organ (taste).The eyes are also boneless sensory organs (sight).Technically speaking, the skin is also a boneless sensory organ (touch).The nose and ears, which are sensory organs, have bones in them,
The localization of a brain and specialized sensory organs of an animal's head is known as cephalization. This presumed evolutionary process focuses on the creation of sensory organs in the anterior end of the head.
The organs are located between the ribs and the top of the hips.
