13. Distribution of corticotropin-releasing factor receptors in primate brain.
The distribution and properties of receptors for corticotropin-releasing factor (CRF) were analyzed in the brain of cynomolgus monkeys. Binding of [125I]tyrosine-labeled ovine CRF to frontal cortex and amygdala membrane-rich fractions was saturable, specific, and time- and temperature-dependent, reaching equilibrium in 30 min at 23 degrees C. Scatchard analy

14. Nervous system distribution of the serotonin 5-HT3 receptor mRNA.
The serotonin 5-HT3 receptor subtype has been implicated in many brain functions. Antagonists of this receptor have anxiolytic and antiemetic effects in humans and in animal models. To determine with cellular resolution the distribution of 5-HT3 receptor mRNA, in situ hybridization was performed in sections of mouse brain and dorsal root ganglia. Scattered l

15. Muscarinic responses of rat basolateral amygdaloid neurons recorded in vitro.
1. Intracellular recordings were obtained from pyramidal-type neurons in the basolateral amygdaloid nucleus (BLA) in slices of rat ventral forebrain and used to compare the actions of exogenously applied cholinomimetics to the effects produced by electrical stimulation of amygdalopetal cholinergic afferents from basal forebrain. 2. Bath application of carbac

16. Quantitative autoradiographic localization of [3H]imipramine binding sites in the brain of the rat: relationship to ascending 5-hydroxytryptamine neuron systems.
Quantitative autoradiography shows that there is a close relationship between [3H]imipramine binding sites and the distribution of 5-hydroxytryptamine (5-HT) neurons in the rat brain. High labeling is observed in the midbrain raphe nuclei, the areas of the dopamine cell groups of the substantia nigra and of the ventral tegmental area of Tsai, the ventral amy

17. Olfactory fear conditioning induces field potential potentiation in rat olfactory cortex and amygdala
The widely used Pavlovian fear-conditioning paradigms used for studying the neurobiology of learning and memory have mainly used auditory cues as conditioned stimuli (CS). The present work assessed the neural network involved in olfactory fear conditioning, using olfactory bulb stimulation-induced field potential signal (EFP) as a marker of plasticity in the

18. Differential Fear Conditioning Induces Reciprocal Changes in the Sensory Responses of Lateral Amygdala Neurons to the CS+ and CS−
In classical fear conditioning, a neutral sensory stimulus (CS) acquires the ability to elicit fear responses after pairing to a noxious unconditioned stimulus (US). As amygdala lesions prevent the acquisition of fear responses and the lateral amygdaloid (LA) nucleus is the main input station of the amygdala for auditory afferents, the effect of auditory fea

19. Telencephalon-specific antigen identified by monoclonal antibody.
Immunohistochemical screening of monoclonal antibodies (mAbs) raised against fractions rich in the dendrodendritic synaptosomes of the rabbit olfactory bulb revealed that one of the mAbs (mAb 271A6) recognized a telencephalon-specific antigen or antigens. Thus, the stain with mAb 271A6 was observed throughout the gray matter of all regions of the neocortex,

20. Expression of pro-opiomelanocortin-like gene in the testis and epididymis.
Adrenocorticotropin (ACTH), beta-endorphin, and the melanocyte-stimulating hormones (MSHs), which are products of a common precursor, pro-opiomelanocortin (POMC), are present in a variety of tissues other than pituitary. The recent detection of immunoreactive POMC-derived peptides in the male reproductive tract raised the possibility that these hormones migh

21. Occurrence of two somatostatin variants in the frog brain: characterization of the cDNAs, distribution of the mRNAs, and receptor-binding affinities of the peptides.
In tetrapods, only one gene encoding a somatostatin precursor has been identified so far. The present study reports the characterization of the cDNA clones that encode two distinct somatostatin precursors in the brain of the frog Rana ridibunda. The cDNAs were isolated by using degenerate oligonucleotides based on the sequence of the central region of somato
