Distributions Of Axons Immunoreactive For Alpha-Melanocyte Stimulating Hormone And Neurons Immunoreactive For Neuronal Nitric Oxide Synthase In The Hypothalamus Of The Adult Male Rat: An Analysis Of Interactions And Their Representation In An Atlas Reference Space, Eduardo Peru
Open Access Theses & Dissertations
In the present study, we have provided two sets of high spatial-resolution maps for neuronal populations containing the immunoreactive presence of the key feeding-related peptides hypocretin/orexin (H/O), alpha-melanocyte stimulating hormone (αMSH) and the nitric oxide-producing enzyme, neuronal nitric oxide synthase (nNOS). These were mapped across the mediolateral and dorsoventral extents of the hypothalamus in the Swanson rat brain atlas, from levels 23–30. The first set of these maps are of the chemoarchitectural distributions for each of the neuronal populations mentioned, which are novel in two ways. First, they were generated across multiple animals to serve as the basis for probability …

The hypothalamus is a major integrator of homeostatic signals in the brain; within the hypothalamus, there are sub-regions with specific roles in regulating energy balance. For example, the lateral hypothalamic area (LHA) has been classically associated with feeding behaviors, and contains two major orexigenic cell populations expressing the neuropeptides melanin concentrating hormone (MCH) or hypocretin 1/orexin A (H/O). Similarly, the paraventricular nucleus of the hypothalamus (PVH) integrates information to mediate neuroendocrine and autonomic responses related to ingestive behaviors. The PVH has also been implicated directly in the control of feeding. However, the precise structural and functional interactions between these two …
