Answer:

Once tactile stimuli are converted into neural signals by the sensory receptors in the skin, the sensory nerves carry the signals to the spinal cord. They are then carried to the thalamus for initial processing. From the thalamus, the majority of neural signals concerning touch are relayed to the somatosensory cortex in the parietal lobe. The brain determines where the body was touched based on the location of the sensory nerves that sense the touch stimuli.

Stimuli connects to signals connected to the brain. It can use cell communication to contact nerves so the nerves would be "disturbed" and react to it.
