The Effects of Maternal Administration of Methadone on Beta-endorphin Content in the Brain and Pituitary of the Rat Progeny
… then determined in the midline telencephalon, diencephalon, medulla-midbrain, and whole pituitary by radioimmunossay. Protein content was also measured. In addition, a number of maternal and progenial morphological parameters were monitored throughout the study.</p> <p>The results indicate that …

The causal role of mood in confabulation
… during an operation to remove a tumour from the diencephalon and frontal lobes, a man (CA) presented with confabulatory amnesia. Previous research papers have shown that confabulations (CA's included) have a positive emotional bias and Turnbull et al. (in press) have demonstrated that low mood …

The neurobiology of central dopamine and progesterone in the reproductive cycle of the ring dove (Streptopelia risoria)
… increased progesterone concentrations in the diencephalon of male brooding doves compared with non-breeding male doves. Measurement of 3[3-HSD enzymatic activity confirmed the synthesis of progesterone in the ring dove diencephalon. This may be sexually differentiated and mediated by …

Tissue Parameter Mapping in Children with Fetal Alcohol Spectrum Disorders
… accumbens, putamen, choroid plexus, ventral diencephalon (DC), right vessel and ventricles. Significant T2 differences were found in the caudate, brain stem, corpus callosum (CC), amygdala, cerebral cortex, choroid plexus, vessels and ventricles. Significant T2* differences were found in the …

Diazepam administration during acute thiamine deficiency attenuates subsequent neuropathology and spatial-memory deficits in rats
… thought to result from damage in areas of the diencephalon that are selectively vulnerable to the metabolic disruption of thiamine deficiency. However, a high incidence of seizures during the late stages of PTD treatment complicates this interpretation, as these seizures may contribute to the …

A Lamprey Gonadotropin-releasing Hormone in the Bovine Brain
… was found bound to neuronal membranes in the diencephalon region of the fetal brain at all ages studied. Additionally, GnRH receptor antibody was found on fetal anterior pituitary cells colocalized with FSH. These results indicate that the lamprey-GnRH-III analog or a closely related peptide …

Identificação dos núcleos pré-familiares em Mocó (Kerodon rupestris): citoarquitetura e imunoistoquímica para NOS
The hypothalamus is a part of the diencephalon responsible for many homeostatic proccess essential to life. Inside the mammillary area, the premammillary area is characterized by the presence of two nuclei, the ventral premammillary nucleus (PMV) and the dorsal premammillary nucleus (PMD). The PMV …

Molecular responses of neonatally heat stressed broilers exposed to acute heat stress
… profile of heart, brain (telencephalon, diencephalon, brain stem, cerebellum) and liver tissues during exposure to an acute heat challenge were studied. In addition, body temperature during neonatal heat exposure was monitored. A significant increase in body temperature was observed …

Neurogenomic dynamics following social interactions in male threespined sticklebacks
… sticklebacks. I focused on two brains regions (diencephalon and telencephalon), which contain several nuclei of the social decision-making network. The third chapter focused on the transcriptomic and epigenomic responses to a territorial challenge. Results showed that the genome dynamically …

Prdm13, a Direct Downstream Target of Ptf1a, Regulates the Balance of Gabaergic Neurons versus Glutamatergic Neurons in the Dorsal Spinal Cord
… that of Ptf1a in the spinal cord, cerebellum, diencephalon, and retina, and Ptf1a is the primary factor required for Prdm13 expression. Furthermore, I demonstrate that Prdm13 functions as a transcriptional repressor to actively suppress the excitatory cell fate by binding to specific …

Effects of dietary tyrosine and tryptophan supplementation on immunity and brain neurotransmitter levels after SRBC injections in chickens
… 5-HIIAA, and S-HIAA/5-HT ratios in the diencephalon, telecephalon, and brain stem in Leghorns. Tryptophan supplementation caused a dose-response increase in S-IIT and S-IHIAA levels of the brain stem. The results demonstrated that 0.5-1% dietary tryptophan supplementation suppressed …

Role of Xenopus Pitx3 during early development.
… of the lens, optic vesicle, optic nerve, and diencephalon. Expression of a xPitx3/engrailed repressor chimera alters early expression domains of Pax6, Rx, and Six3, and later inhibits lens development consequently abrogating retinal induction. This later inhibition of eye development is …

Interplay between Piezo1-mediated mechanosensing and the chemical guidance cue Semaphorin3A during development of the embryonic nervous system
… chiasm and continue their journey through the diencephalon as an optic tract, before reaching their target, the optic tectum. During formation of the optic tract, RGC axons respond to both chemical and mechanical signals in the environment. A key player in sensing mechanical cues is the …

In vivo and in vitro guidance of developing neurons by mechanical cues
… RGC axons make a stereotypical turn in the mid-diencephalon, and when they reach their target, respectively. The final path of RGC axon turning followed a clear mechanical gradient: by the later stage, tissue rostral to the OT had become stiffer than tissue caudal to it. This mid-diencephalic …

The mechanical regulation of Eph/ephrin signalling in the developing Xenopus brain
… tract and found a stiffness gradient across the diencephalon-tectum boundary at the time of innervation by RGC axons. To characterise how substrate stiffness affects axon fasciculation independently of chemical cues, I developed an in vitro assay combining stiffness gradient hydrogels and …

The role of tissue viscoelasticity in axon guidance during Xenopus brain development
… the optic tectum. On their way through the mid-diencephalon, they turn caudally in response to gradients of the chemical guidance cues Semaphorin3A, Slit 1 and Slit 2 as well as tissue elasticity. However, while the importance of elasticity is becoming well-accepted in the context of …
