The electrical signals then undergo neural processing. The path followed by a particular signal depends on what type of signal it is (i.e. an auditory signal or a visual signal).
Through the series of interconnect neurons located throughout the body, electrical signals are propagated from the receptors cells to the brain. In our previous example, the image of duck floating in the pond is received as light on the retina, which is then transduced into an electrical signal and then processed through the neurons in the visual network.
In the next step of the perceptual process, you will actually perceive the stimuli and become aware of its presence in the environment.
