Participation in a reflection group of neurons in the reflex arc of the central and integrated part of the central nervous system. Such as participation in the central structure of the pupillary light reflex is called the light reflex center.

It is involved in a reflection of the neuronal activity in the central nervous system, is a reflection of the hub, consolidation. For example, by participating in the pupillary light reflex hub structure is called Optical reflection hub.

Is participates in some reflection activity the neuron group in the central nervous system, is the reflex arc main center conformity part.For example participates in the pupil to the light reflection main center structure named to the light reflex center.

Is involved in a reflection activity within groups of neurons in the central nervous system, is the Central consolidated part of the reflex arc. For example participation in the central structure of the pupillary light reflex is called the light reaction Central.
