This ease of passage is achieved at the cellular level. The brain/control center of the nervous system sends its signals through nerves made up of nerve cells. At its most basic level, a nerve cell is made up of a central processing unit, a long sending fiber (axon), and many small receiving tendrils (dendrites). Frequently used axons form boutons, the French word for "bumps." The more boutons, the faster the message is sent.
However, once these boutons are formed, they can't be un-formed. This is why habits are so hard to break. The best way to break a habit, then, is to form a stronger nervous connection through more repetitions than with the bad habit.

People become nervous because their sympathetic nervous system produces too much adrenaline.

Cephalization is the process in animals by which nervous and sensory tissues become concentrated in the "head." The evolution of a head allows scientists to distinguish between the head end, or anterior, and the opposite end, the posterior.

Just stay calm, breath and relax, once the horse realizes that your relaxed and supple, they will become relaxed to. Don't freak yourself out, the horse can tell if your afraid or nervous. The chances are if your tense and nervous, the horse will become tense and nervous, which will freak you out, and I think we all know how that will turn out.
It is not so reliable to set it on automatic, because the sensor may become unoperative suddenly.
The pattern of behavior that has become dull but hard to change is known as a habit loop. This loop consists of a cue that triggers the behavior, the routine behavior itself, and a reward that reinforces the behavior. Breaking this pattern requires identifying and changing the cue or the routine in order to establish a new, more positive habit.
