In contrast to what we know about the fruit fly, we do not know what brain structures or genetic mechanisms are involved in the different expressions of courtship disorder in human males. It may someday be possible to use a sophisticated modeling method to assess the feasibility of the theory of courtship disorder. Neuropsychologists who analyze reading impairments (dyslexia) in patients with brain lesions have found regularities in the kinds of reading mistakes these patients make. These regularities serve as the basis of current models of neural processing of language (e.g., Caramazza & Hillis, 1990). These models suggest that the brain processes features of written text in parallel rather than in sequence, and that different kinds of mistakes are caused by errors in different paths.
A relatively recent and exciting development in this area is connectionist modeling or neural networking (Hinton & Shallice, 1991), which uses computer simulations of idealized networks involving large numbers of relatively simple processing elements. Hinton and hiscolleagues have used neural networking to generate sophisticated models for understanding dyslexia and providing insights into the neural architecture underlying certain language functions. In contrast to traditional linear statistical approaches, the nonlinear modeling available through neural networking can control hypothesis building in a much more complex way. This approach appears to be the method of choice for a future analysis of the feasibility of the different hypotheses regarding courtship disorder. Similar to the work in langu'age processing, this kind of computer simulation might begin with a hypothetical reconstruction of pathways activated in the course of normative sexual arousal and activities. Speculations about missing or faulty components (Le., processing pathways) that result in the various paraphilic expressions could inform hypotheses about how components are related in normal courtship. For example, some components may be involved in regulating reward during the various courtship phases that increases the probability of progressing to the next phase. Another example is the influence of a female's actions on a male's behavior in terms of staying in a particular courtship phase, advancing to the next phase, retreating to the previous phase, or breaking
from any further sexual interaction. There may be several components involved in the processing of female signals and determining the male's ability to respond appropriately and effectively. In the future, the neuropsychological analysis of cognitive processes may also utilize magnetic source imaging (e.g., Gallen et aI., 1993), a technology combining- magnetoencephalographic scanning and magnetic resonance imaging. Magnetic source imaging permits inferences about the spatial locations of neural regions associated with normal and pathological activity patterns. It will, however, likely be a long time before this technology is fully realized and subcortical and cortical models of paraphilias can be adequately explored.
