“…The superposition of the Nissl based cytoarchitectonic parcellation scheme of Seeger (1987) onto the neurochemical findings of van and Vellucci and Parrott (1997) divides the pig Pa into three major subdivisions (Raymond et al, 2006). Accordingly, the pig Pa can be divided into a medial parvicellular part (PaMP), a medial magnocellular part (PaMM) and a lateral magnocellular part (PaLM).…”

“…However, this neuronal cluster is spatially separated from the paraventricular nucleus and more loosely organized. Furthermore, all previous descriptions of the porcine magnocellular system have excluded this neuronal population from the paraventricular nucleus Vellucci and Parrott, 1997;Raymond et al, 2006).…”

“…Previous cytoarchitectonic descriptions of the porcine hypothalamus have been based on Nissl stained material and provided little detail about the organization of the preoptic and anterior hypothalamic regions (Solnitzky, 1939;Yoshikawa, 1968;Szteyn et al, 1980;Seeger, 1987;Seeger, 1990;Felix et al, 1999). Furthermore, previous chemoarchitectonic descriptions of the pig hypothalamus have either focused on the magnocellular neurophysin containing system or were based on single immunohistochemical markers (Cassone et al, 1988;van Eerdenburg et al, 1990;Leshin et al, 1995Leshin et al, , 1996Vellucci and Parrott, 1997;Rankin et al, 2003;Li et al, 2005;Raymond et al, 2006;Su et al, 2008).…”

“…In the rat, postpartum maternal experience was found to increase the survival of new cells in the nucleus accumbens and bed nucleus of the stria terminalis, but not amygdala, following pup interactions (Akbari et al, 2007). Neurogenesis in the hypothalamus of lactating pigs has also been examined but no changes were observed (Raymond et al, 2006). Importantly, these areas are known to be critical for the expression of maternal care as well as maternal aggression and other behavioral processes that are altered during parenthood such as motivation and anxiety (Numan and Insel, 2003).…”

The maternal brain is remarkably plastic and exhibits multifaceted neural modifications. Neurogenesis has emerged as one of the mechanisms by which the maternal brain exhibits plasticity. This review highlights what is currently known about peripartum-associated changes in adult neurogenesis and the underlying hormonal mechanisms. We also consider the functional consequences of neurogenesis in the peripartum brain and extent to which this process may play a role in maternal care, cognitive function and postpartum mood. Finally, while most work investigating the effects of parenting on adult neurogenesis has focused on mothers, a few studies have examined fathers and these results are also discussed.

“…Two-day-long male exposure increased the number of new formed cells in amygdala and hypothalamus in comparison to condition of female exposure and social isolation (Fowler et al 2002). Moreover, immunohistochemical staining of female pig hypothalamus have revealed that new oxytocin-containing neuron formation rate in paraventricular nucleus (PVN) is greater in lactating sow and adult gilts in comparison to puberty ones (Raymond et al 2006). In another study held on female pigs, formation rate of new neurons expressing vasopressin in vasopressin and oxytocin-containing nucleus (VON) was positively correlated with the growth of this brain region—more newly formed vasopressin positive neurons were shown in adult pigs, than in adolescent individuals (Rankin et al 2003).…”

The discovery of undifferentiated, actively proliferating neural stem cells (NSCs) in the mature brain opened a brand new chapter in the contemporary neuroscience. Adult neurogenesis appears to occur in specific brain regions (including hypothalamus) throughout vertebrates’ life, being considered an important player in the processes of memory, learning, and neural plasticity. In the adult mammalian brain, NSCs are located mainly in the subgranular zone (SGZ) of the hippocampal dentate gyrus and in the subventricular zone (SVZ) of the lateral ventricle ependymal wall. Besides these classical regions, hypothalamic neurogenesis occurring mainly along and beneath the third ventricle wall seems to be especially well documented. Neurogenic zones in SGZ, SVZ, and in the hypothalamus share some particular common features like similar cellular cytoarchitecture, vascularization pattern, and extracellular matrix properties. Hypothalamic neurogenic niche is formed mainly by four special types of radial glia-like tanycytes. They are characterized by distinct expression of some neural progenitor and stem cell markers. Moreover, there are numerous suggestions that newborn hypothalamic neurons have a significant ability to integrate into the local neural pathways and to play important physiological roles, especially in the energy balance regulation. Newly formed neurons in the hypothalamus can synthesize and release food intake regulating neuropeptides and they are sensitive to the leptin. On the other hand, high-fat diet positively influences hypothalamic neurogenesis in rodents. The nature of this intriguing new site of adult neurogenesis is still so far poorly studied and requires further investigations.
