Sensory processes

The second is that the initiated signal is the smallest building-element of a peripheral information-pattern extending into the space in which it happens to be generated the nature of the dimension of this space depends on the sensory process involved. 

Salamone, Cousins and Snyder (1997) in fact suggest that the function of DA in the nucleus accumbens should not be described by terms such as motivation, reinforcement and reward. Rather it should be considered to mediate the higher-order motor and sensory processes that are important for the activation of aspects of motivation and responsiveness to conditioned stimuli. 

The early VN neurones migrate by various routes and in mammals become organised into two layers, each with distinct functional attributes (Chaps. 2 and 6). Amongst marsupials, the sensory cells of an opossum appear at about one-week post-conception (Jia and Halpem, 1998). Despite their extremely altricial developmental pattern, the bandicoots dendrites produce sensory processes (Fig. 4.5) on the lumenal border of the VNO at 35 days postnatal, which in the Northern Bandicoot (Isoodon macrourus) is about 50% of pouch life (Kratzing, 1986).

Whether subthreshold doses in animals can produce any animal neurobehavioral component of the loosening of inhibition and inner-directed attention sought for by some clinicians in using less potent drugs for a kind of psychosynthesis is uncertain. Sensitization and habituation studies implicate raphe function but not in any simple way (32), and pavlovian studies show very low dose effects on sensory processing (39,43).

In each case, chemometrics plays an essential role in data processing, which corresponds to the brain elaboration of exteroceptive stimuli in mammalian sensory processes. A clever employment of chemometric tools is thus essential for obtaining reliable and valuable results.

With exposures to drugs severe enough to kill nerve cells or parts of cells, longterm, often permanent, deficits in sensory processes, motor function, behavior, learning capacity, and memory can occur. Since neurons do not reproduce, recovery of lost function occurs only if the remaining nervous system can take over the functions of the cells that were killed. Less severe exposures will modify function, often profoundly, until the drug is eliminated from the body. In most cases, normal behavior returns, and there may be no evidence of chronic consequences. With repeated exposures to some substances, however, the consequences may take on an irreversible quality.
