Sensory Nerves and Receptors
... All stimuli are transduced by the sensory receptors into nerve impulses in the afferent nerves. These impulses reach the brain acting as code signals specific for each sensation. The brain then deciphers these code signals and identifies the modality (type), the locality and the intensity of the sti ...
