The sense of the spirit as a form of conversation.

Experiential evidence suggests that the main features of spiritual experience are euphoria, and a feeling of the expansion and unification of consciousness. A way towards understanding this state and how it might arise comes from a consideration of a state in which these features are lacking. Such a state is borderline personality disorder, central to which is a "painful incoherence" that is not merely "psychological" but can be demonstrated neurophysiologically. The phenomena of the borderline syndrome can be understood as failure of proper maturation of the experience of "self," conceived as higher order consciousness in a notional hierarchy of consciousness. Spiritual experience is understood as a state "larger than self." Since both the achievement of a sense of the spirit and recovery from borderline personality disorder (BPD) involve an ascent in a hierarchy of consciousness, they may have a common basis. The approach to the development of self is derived from developmental observations which suggest that it depends upon a particular form of conversation, the first form of which is shown in the first months of life as a proto-conversation. It has the characteristics of an analogical relatedness. Symbolic play arising at the second year of life, shows a partial internalization of this relatedness. Symbolic play is accompanied by a quasi-inner conversation with an illusory other who is both self and the mothering figure. It is suggested that this is the embryonic form of the "conversations" of mystics in communion with self and God.

Distinct pattern of P3a event-related potential in borderline personality disorder.

P3a and P3b event-related brain potentials to auditory stimuli were recorded for 17 unmedicated patients with borderline personality disorder, 17 matched healthy controls and 100 healthy control participants spanning five decades. Using high-resolution fragmentary decomposition for single-trial event-related potential analysis, distinctive disturbances in P3a in borderline personality disorder patients were found: abnormally enhanced amplitude, failure to habituate and a loss of temporal locking with P3b. Normative age dependencies from 100 controls suggest that natural age-related decline in P3a amplitude is reduced in borderline personality disorder patients and is likely to indicate failure of frontal maturation. On the basis of the theories of Hughlings Jackson, this conceptualization of borderline personality disorder is consistent with an aetiological model of borderline personality disorder.
