Early and recent studies show that dopamine through its neuronal systems and receptor
subtypes plays different roles in the control of male sexual behavior. These studies show …

The epidemiology, etiology and proposed treatments for the sexual desire disorders are
briefly reviewed before turning to an analysis of preclinical models. We suggest that the …

There is much evidence that naturally occurring behaviors (eg, the ingestion of food and
water) and social behaviors (eg, play, maternal behavior) can induce a reward state. This …

There are some apparently healthy male rats that fail to mate after repeated testing with
receptive females. We have previously shown that these “non-copulator (NC)” males show …

Various lines of research indicate that sexual reward is mediated by opioids in both males
and females. In the first part I review basic ideas about sexual reward in humans followed by …

Sexual behavior is activated by motivation. An overwhelming majority of experimental
studies of the intricacies of sexual motivation has been performed in rodents, most of them in …

In some species, including gerbils, guinea pigs, mice, rams and rats, some apparently
normal males fail to mate. These kinds of animals have been named 'noncopulating (NC)' …

Different conditions induce proliferation, migration and integration of new neurons in the
adult brain. This process of neurogenesis is a clear example of long lasting plastic changes …

One approach to study interactions between behavior and genetics is to use inbred mice
with different genetic backgrounds. To examine the effect of background on a specific gene …

Alzheimer׳ s disease (AD) is characterized by a number of alterations including those in
cognition and olfaction. An early symptom of AD is decreased olfactory ability, which may …
