Stimulus is then transformed into another form which becomes a representation of the stimulus. Everything we perceive is based on electrical signals in our nervous system which are created in the receptors + transform energy from the environment into electrical signals in the nervous system through a process called transduction. Transformation of one form of energy into another form of energy. Occurs in the nervous system when energy in the environment is transformed into electrical energy. Electrical signals activate other neurons, which in turn activate more neurons.
