Document Summary
When human cognition is involved, a system failure resulting in an accident, is often attributed simply to. Feedback loops where the output is compared to desired system performance, and corrections are made as necessary. Consists of the brain and spinal cord (cns), and a network of nerves throughout the body (pns) Highly complex, both in the organization of control functions in the brain, and in how these functions are carried out via the nerves throughout the body. Ns controls include both voluntary and involuntary functions. Common involuntary functions: blushing, butterflies in stomach, hiccups, goosebumps, head jerk when falling asleep. Efferent nerves carry control signals to various organs while afferent nerves carry signals from external to internal sensors to the cns (ex: touch, pressure and pain sensors on skin) Signals form the input and may come directly from the environment or be provided through a display, displays may use one or more senses.
