after the brain receives information from the body's sensory receptors, what is the next step in responding to this information?
Bumek [7]

The sensory receptors refer to the portions of the nervous system, which sense variations in the external or internal surroundings. The sensory input can be in various forms, comprising taste, pressure, light, sound, pH of blood, or levels of hormones, which are transformed into a signal and are transmitted to the brain or spinal cord.  

In the sensory centers of the brain, the barrage of information is integrated and a response is produced. The response, that is, a motor output refers to a signal conducted towards organs via motor neurons, which then transforms the signal into some kind of action, like changes in heart rate, movement, discharge of hormones, and others.
