Psyche and Neurosis

In the past century, and especially in the past half-century, thanks to technological development, Neurology has been growing exponentially, as the direct study of the Nerve has become feasible.  As a result, observable chemical and electrical processes has rendered all previous connotations of 'nerves' and 'nervous' obsolete.  Likewise, the current meaning of 'neurosis'--literally, a disorder of a nerve--bears little resemblence to that of its prominent usage a century ago, as is evidenced by the fact the treatment of such disorders is now universally pharmacological, not psychoanalytical.  In other words, Freud's concept of Neurosis, one of the centerpieces of his practice, is not merely obsolete, but is a reflection of a concept of the Psyche which is Phenomenalist, with no neurological correlate, e. g. an Oedipus Complex absent any corresponding neural malfunctioning.
