WebCertain opioid receptor types appear to be linked to independent respiratory functions. For instance, mu receptors in the brain stem produce strong inhibitory actions on respiratory parameters, including RR, VT, VE, and CO2 sensitivity. These effects have been observed in vivo and by electrophysiologic recordings in vitro. WebAug 14, 2024 · Patch-clamp and multielectrode array recordings in brain slices showed that CTZ or light stimulation facilitated synaptic transmission and induced neuroplasticity mimicking the LTP of EPSPs.

The chemoreceptor trigger zone (CTZ) is an area of the medulla oblongata that receives inputs from blood-borne drugs or hormones, and communicates with other structures in the vomiting center to initiate vomiting. The CTZ is located within the area postrema, which is on the floor of the fourth ventricle and is … See more The CTZ is in the medulla oblongata, which is phylogenetically the oldest part of the central nervous system. Early lifeforms developed a brainstem, or inner brain, and nothing more. This part of the brain is responsible for … See more This integrates the emetic response. This is the area in which "a final decision is made" about whether to evoke an emetic response. This decision is based heavily on the information which the CTZ relays to the rest of the vomiting center, but also the chemoreceptors in the See more Antiemetic medications often target the CTZ to completely inhibit or greatly reduce vomiting. Most of these work by not allowing certain … See more Since the CTZ is located in the area postrema, a sensory circumventricular organ, it does not have a blood–brain barrier.
