Nerves allow us to perceive the environment while the brain integrates the incoming signals to determine an appropriate response. CB 48. 3

At the synapse the electrical signal is converted to a chemical signal electrical at synapse chemical electrical

Neurons are commonly connected to many other neurons, and the effect of the different incoming signals determines what the neuron will do. CB 48. 16

The brain and the central nervous system integrate the various incoming signals CB 48. 19
