When considered together, the data present a peculiar pattern. Usually these changes take the form of what is known as a deficit—that is, an impairment of the ability to act or think in some way. A new, very efficient perfusion-sensitive technique has made it possible to clarify the association between handedness and language dominance in healthy subjects in a representative and quantitative way.

At about the same time, the concept of degeneration, taken from French psychiatry, was introduced to explain this behavior. Psychopaths are at increased risk of engaging in both reactive and instrumental aggression.

Furthermore, patients who present with language disturbances after right-sided cerebral infarction have not infrequently had strokes in the other hemisphere, rendering conjectures on the original hemisphere of language dominance unreliable Pedersen et al.

In hairless skin both rapidly and slowly adapting receptors provide information about the force of mechanical stimulation.
