Preoptic

GnRH1-producing neurons in regions of the brain known as the preoptic and hypothalamic regions in arrhinencephalic fetuses, whereas large numbers of these cells were present in control fetuses. ❋ Unknown (2010)

As a male neurologist, I can tell you that less than 0.25% of brain mass is sexually dimorphic hypothalamic preoptic area, ventromedial nucleus and supraoptic area and that is hypothalamic, related, so far as we know, to chemical and hormonal regulation. ❋ Unknown (2005)

There were also odd activity patterns in the medial preoptic area of the hypothalamus. ❋ Unknown (2004)

This manipulation also increased c-Fos expression in structures including the ventral tegmental area, medial shell of the nucleus accumbens, medial prefrontal cortex, septal area, preoptic area, lateral hypothalamic area and dorsal raphe nucleus. ❋ Unknown (2010)

Picrotoxin administration into the SuM appears to disinhibit local neurons and recruits activation of brain structures associated with motivational processes, including the mesolimbic dopamine system, prefrontal cortex, septal area, preoptic area, lateral hypothalamic area and dorsal raphe nucleus. ❋ Unknown (2010)

The SuM appears to be functionally linked with the mesolimbic dopamine system and is closely connected with other brain structures that are implicated in motivational processes, including the prefrontal cortex, septal area, preoptic area, lateral hypothalamic area and dorsal raphe nucleus. ❋ Unknown (2010)

Using this panic model, we previously showed that inhibiting the anterior third ventricle region (A3Vr; containing the organum vasculosum lamina terminalis, the median preoptic nucleus, and anteroventral periventricular nucleus) attenuates cardiorespiratory and behavioral responses elicited by i.v. infusions of NaLac. ❋ Andre I Molosh (2010)

Using studies of embryonic mice, Corbin and his team located two specific pools of precursor cells marked by the transcription factor Dbx1 that migrate from both the ventral pallium and the preoptic area - a previously undiscovered pool of migratory cells - to create the requisite mix of excitatory and inhibitory neurons that ultimately comprise the amygdala. ❋ Unknown (2009)

Humoral and visceromotor responses are then initiated by the medial preoptic area of the hypothalamus ❋ Unknown (2009)

Remarkably, the preoptic area precursor cells are exclusive contributors to the development of the limbic system, and no other portion of the brain. ❋ Unknown (2009)

- This area is normally inhibited by signals from the heat center in the anterior hypothalamic-preoptic area but is excited by cold signals from the skin and spinal cord. ❋ Unknown (2009)

Neuron firing is inhibited during sleep by a system of GABA containing neurons and the active state of ventrolateral preoptic nucleus. ❋ Unknown (2009)

Neurons in the SCN send axonal projections to hypothalamic and non-hypothalamic target regions involved in reproduction, including the medial preoptic area, the gonadotropin-releasing hormone (GnRH) neurons, and the autonomic nervous system. ❋ Unknown (2009)
