 Although it is usually not recognized in the literature, there are important differences among the phenomena afflicting these patients, which are manifested in patients’ reports and behavior. For instance, pain asymbolia also typically produces a kind of dissociation — a rather strong kind — sometimes similar to cingulotomy patients’ but interestingly different from lobotomy patients’ (Rubins and Friedman 1948; Hurt and Ballantyne 1974; Berthier et al. 1988, 1990; Devinsky et al. 1995; Weinstein et al. 1995). In fact, there is evidence that pain asymbolia may be the only form of genuine dissociation (Grahek 2007). These patients, for instance, don’t react even to momentary pains like pinpricks, small cuts, or burns. Experimental pain stimuli fail to produce any recognizable affective reactions. Nevertheless, the patients insist that the stimuli cause pain — they identify their experiences as pain (Rubins and Friedman 1948; Berthier et al. 1988, 1990; Dong et al. 1994; Weinstein et al. 1995). The lobotomy and morphine patients, on the other hand, do show the usual affective reactions and symptoms when they are stimulated momentarily by normally painful stimuli. But they don’t seem to care or be bothered by their standing persistent or chronic pains. Probably, they still feel the negative affect but don’t mind it, whereas the pain asymbolia patients don’t even seem to feel the momentary negative affect.
