The genus Lepidochitona Gray, 1821 has two species in the Caribbean: L. liozonis (Dall & Simpson, 1901) and L. rosea Kaas, 1972. We describe a third species: Lepidochitona rufoi sp. nov. from Puerto Rico. Lepidochitona rufoi differs from both in having a finely granulose tegmentum, smaller size, a very fine central radula tooth, and different anal plate form and color pattern. It also differs from L. liozonis in having longer marginal spicules.

In this study, we tested whether stimulation of the ventral tegmental area (VTA), the source of the dopamine innervation of the prefrontal cortex,...

    Abstract Serotonin (5-HT) afferents may modulate the dopamine mesoaccumbens circuit, which has been shown to be critically involved in the locomotor stimulatory, discriminative stimulus, and rewarding properties of cocaine. In the present study, we investigated the role of 5-HT[sub 1A] receptors...
