truth. Contextualism and attribution theory The theoretical study of mystical experience has shifted from an experiential, privatised and perennialist approach to a contextual and empirical approach. The contextual approach, which also includes constructionism and attribution theory, takes into account the historical and cultural context. Neurological research takes an empirical approach, relating mystical experiences to neurological processes. Wayne Proudfoot proposes an approach that also negates any alleged cognitive content of mystical experiences: mystics unconsciously merely attribute a doctrinal content to ordinary experiences. That is, mystics project cognitive content onto otherwise ordinary experiences having a strong emotional impact. Objections have been raised concerning Proudfoot's use of the psychological data. This approach, however, has been further elaborated by Ann Taves. She incorporates both neurological and cultural approaches in the study of mystical experience. Many religious and mystical traditions see religious experiences (particularly that knowledge that comes with them) as revelations caused by divine agency rather than ordinary natural processes. They are considered real encounters with God or gods, or real contact with higher-order realities of which humans are not ordinarily aware. Neurological research The scientific study of mysticism today focuses on two topics: identifying the neurological bases and triggers of mystical experiences, and demonstrating the purported benefits of meditation. Correlates between mystical experiences and neurological activity have been established, pointing to the temporal lobe as the main locus for these experiences, while Andrew B. Newberg and Eugene G. d'Aquili have also pointed to the parietal lobe. Recent research points to the relevance of the default mode network. Temporal lobe The temporal lobe generates the feeling of "I", and gives a feeling of familiarity or strangeness to the perceptions of the senses. It seems to be involved in mystical experiences, and in the change in personality that may result from such experiences. There is a long-standing notion that epilepsy and religion are linked, and some religious figures may have had temporal lobe epilepsy (TLE). Raymond Bucke's Cosmic Consciousness (1901) contains several case-studies of persons who have realized "cosmic consciousness"; several of these cases are also being mentioned in J.E. Bryant's 1953 book, Genius and Epilepsy, which has a list of more than 20 people that combines the great and the mystical. James Leuba's The psychology of religious mysticism noted that "among the dread diseases that afflict humanity there is only one that interests us quite particularly; that disease is epilepsy."
