“…After a 6–11-day recovery period, most females (see Design) received intracranial implants of estradiol-17β (E 2 ) using standard stereotaxic techniques and sodium pentobarbital anesthesia. The cannulae used in preparing these implants were lengths of 27 ga. hypodermic tubing (0.008 in inner diameter; Small Parts, Inc.) cut electrolytically (Lewis & Gebhart, 1976) and tapped 30 times in a beaker containing the crystalline hormone. Cannulae were cleaned and checked microscopically before use to ensure that hormone was present just within the lumen of each tube.…”

Ovariectomized female hamsters received small unilateral implants of estradiol at a variety of anterior-posterior levels of the medial preoptic area and hypothalamus. The results of an initial experiment using 27-ga. implants showed that females with estradiol implants in the ventromedial hypothalamus (VMN) or nearby anterior hypothalamus consistently showed higher levels of sexual receptivity than did females with implants farther rostral, in the preoptic area, or farther caudal, in the posterior hypothalamus. A second experiment used smaller, 28-ga. implants to compare directly the two areas at which implants were effective in the first experiment. The results confirm the findings of other recent studies of hamsters and rats by identifying the VMN as the most effective hypothalamic site for the estrogen priming of sexual receptivity.

Modification of ethanol intoxication by dopamine agonists and antagonists

The effects of ethanol on locomotor activity and rotarod performance were measured in the rat. Apomorphine (4 mg/kg s.c.) antagonized and pimozide (0.75 - 1.50 mg/kg s.c.) enhanced the effects of a 2 g/kg dose of ethanol on rotarod performance. No such interaction was seen with pentobarbital, 25 mg/kg, a dose sufficiency to produce an equivalent motor performance deficit. Animals with 6-hydroxydopamine lesions of the substantia nigra were more sensitive to the ethanol-induced impairment of rotarod performance and suppression of locomotor activity than shamoperated controls. The pattern of dopamine depletion in lesioned animals indicated a degree of selectivity of the lesion for the nigrostriatal pathway. The results are compatible with the hypothesis that ethanol interferes with dopaminergic transmission, and that such an interference may be involved in the behavioral effects of ethanol.
