A second, non-CRH subgroup of Bar neurons must control voiding because, in contrast to ablating the BarCRH subgroup, eliminating all glutamatergic neurons here causes severe urinary retention (Verstegen et al. Many neurons in this non-CRH subgroup are identified by their estrogen receptor expression (BarESR1).

BarESR1 neurons project their axons primarily to a central region of the lumbosacral spinal cord (Keller et al. Even when the bladder is empty, stimulating BarESR1 neurons causes EMG bursts in the EUS, similar to spontaneous voiding источник et reliability. While additional work is required to learn whether and how these or other Bar neurons control internal urethral sphincter (IUS) smooth muscle, these results suggest продолжить that the BarESR1 subpopulation is a key node for controlling voluntary initiation of micturition.

Amethia (Lvonorgestrel/Ethinyl Estradiol and Ethinyl Estradiol Tablets)- Multum neurons can trigger voiding and BarCRH neurons augment bladder contraction, but voluntary micturition control requires input from the forebrain.

Many brain regions provide direct input projections to Bar, including the lateral hypothalamic area (LHA), medial preoptic area (POA), bed nucleus of the stria terminalis (BNST), PAG, anterior cingulate cortex (ACC), prelimbic cortex, and primary and secondary motor areas (Moga et al. Recent experimental work has focused largely on excitatory inputs that promote voiding. For example, Bar receives dense, excitatory input from both the PAG and the LHA. Glutamatergic input from both brain regions produces по этой ссылке post-synaptic responses on both BarCRH and non-CRH neurons without preference for either subgroup (Verstegen et al.

Bar also receives direct жмите сюда from the mouse primary motor cortex (M1), which could allow volitional initiation of voiding (Yao et al. It is not yet clear whether axons from any of Amethia (Lvonorgestrel/Ethinyl Estradiol and Ethinyl Estradiol Tablets)- Multum afferent sites selectively target one or the other Bar subpopulation.

These projections offer different pathways for initiating micturition, but not for suppressing the micturition reflex to maintain continent control. We have very little information on the role of inhibitory input to Bar or how urinary continence is maintained in general. Classic studies exploring the brain with electrical stimulation noted that some sites in the medial POA or BNST triggered bladder contractions, while stimulating the lateral POA caused bladder myeloma (Kabat et al.

It remains unclear whether these effects resulted from neurons in those regions or axons passing through them, продолжить the latter finding suggests that inhibitory input from the LPOA to Bar could be important for maintaining continence.

Possibly at odds with this model, injuring the PAG causes urinary retention, not incontinence (Yaguchi et al. Urge incontinence: (A) Amethia (Lvonorgestrel/Ethinyl Estradiol and Ethinyl Estradiol Tablets)- Multum showing a large, contrast-enhancing pituitary adenoma compressing взято отсюда hypothalamus.

This patient presented Amethia (Lvonorgestrel/Ethinyl Estradiol and Ethinyl Estradiol Tablets)- Multum urgency, frequency and daytime incontinence (Yamamoto et al. This patient had florid urinary incontinence, and 2 cm hematoma was found in the left cingulate gyrus (Andrew et al.

Retention: (F) T2-weighted MR images showing hyperintense lesion in the right PAG. This patient presented with an inability to void, which improved with steroid treatment (Yaguchi et al.

Red indicates areas damaged more frequently in retentive relative to non-retentive patients after medullary strokes (Cho et al. Neurologic patients often suffer micturition deficits following strokes, tumors, or other focal brain lesions.

Further, LUTS читать полностью result from peripheral neuropathies or even non-neurologic structural changes, in addition to diseases of the central nervous system. Here, we will instead focus on information derived from the analysis of focal brain injuries that produce acute-onset symptoms, which offers cause-and-effect information about the regions necessary for normal urinary continence.

Similar to experimental animal studies, lesions in the pons-midbrain, medulla, and spinal cord produce urinary retention with detrusor underactivity (Figure 1, red). In взято отсюда case, acute urinary retention and bladder sensation was caused источник a lesion in the midbrain PAG (Yaguchi et al.

Another study saw that in patients with Amethia (Lvonorgestrel/Ethinyl Estradiol and Ethinyl Estradiol Tablets)- Multum sclerosis, bladder hyporeflexia correlated to pontine lesions (Araki et al. Amethia (Lvonorgestrel/Ethinyl Estradiol and Ethinyl Estradiol Tablets)- Multum a patient with herpetic brainstem encephalitis causing a unilateral lesion in the upper pons developed urinary retention (Sakakibara et al.

Two studies that looked at the medulla found that lesions producing urinary retention typically involve the lateral medulla, which contains axons running from Bar to the spinal cord (Cho et al. In contrast to brainstem and spinal cord lesions, forebrain lesions that alter micturition typically cause по этому сообщению and incontinence, not urinary retention (Figure 1, green). Their incontinence appeared acutely and did not result from cognitive or gait impairments that can also arise with frontal lobe damage.
