Thalamocortical axons (TCAs) originate in dorsal thalamus, extend ventrally along the lateral thalamic surface, and as they approach hypothalamus make a lateral turn into ventral telencephalon. In vitro studies show that hypothalamus releases a chemorepellent for TCAs, and analyses of knockout mice indicate that Slit chemorepellents and their receptor Robo2 influence TCA pathfinding. We show th...

Groups of pregnant rats were injected with two successive daily doses of 3H-thymidine from gestational day 13 (E13 + 14) until the day before birth (E21 + 22). This double labelling procedure was combined with an injection schedule of a single day delay between groups (E13 + 14; E14 + 15; E15 + 16 . .). The two injections assured the comprehensive labelling of practically all neurons of a given...

The adipose tissue-derived hormone leptin regulates body weight homeostasis by decreasing food intake and increasing energy expenditure. The weight-reducing action of leptin is thought to be mediated primarily by signal transduction through the leptin receptor (LR) in the hypothalamus. We have used immunohistochemistry to localize LR-immunoreactive (LR-IR) cells in the rat brain using an antise...

The spinal and peripheral innervation of the clitoris and vagina are fairly well understood. However, little is known regarding supraspinal control of these pelvic structures. The multisynaptic tracer pseudorabies virus (PRV) was used to map the brain neurons that innervate the clitoris and vagina. To delineate forebrain input on PRV-labeled cells, the anterograde tracer biotinylated dextran am...

The effects of ovariectomy and its interaction with body weight on the recovery period following lateral hypothalamic lesions were examined. The results of the experiments indicated that body weight set point prior to lesioning, liable to be influenced by hormonal and metabolic factors, is a more important variable in modifying the recovery process after lateral hypothalamic lesions than is abs...

The thalamo-amygdaloid connections arising in the posterior thalamus were studied in the brains of rats by the Nauta-Gygax and Fink-Heimer methods. They begin mainly in the neurons of the supero-medial area of the posterior segment of the pulvinar and in the peripeduncular nucleus. The amygdalopetal fibers of this pathway pass through the zona incerta, cerebral peduncle, and the lateral hypotha...

The contributions of /Si-, B -̂, and a2-adrenoceptors in the posterior hypothalamus to the increased renal sympathetic nerve activity and decreased urinary sodium excretion resulting from environmental stress (air jet) in conscious spontaneously hypertensive rats were examined. Air stress increased mean arterial pressure and renal sympathetic nerve activity (54% from 7.0 ± 0.7 integrator resets/...
