Solution

TONOTOPY- IT is the spation arrangement of processed sounds of different frequencies in the brain. this begins in cochlea. then following several steps finally binural fusion in the superior olivery complex occur. here large amount of information is encoded in the signal strenght of each ganglion. in humans 6 tonotopic maps are identified in primary auditory complex.

SOMATOTOPY- It is the topographic association of positional relationship of receptors in the body . it networks through respective nerve fibres to their terminal distribution in specific unctional areas of cerebral cortex.
