"Periaqueductal" Meaning
The periaqueductal area refers to a region in the brainstem that surrounds the aqueduct of Sylvius, a narrow channel that connects the third and fourth ventricles of the brain. The periaqueductal grey (PAG) is a specific part of this area that plays a crucial role in the regulation of pain, emotional response, and other physiological processes. The PAG is also involved in the transmission of pain signals from the periphery to the brain, and is a target for endogenous analgesic compounds such as endorphins and other opioids.
"Periaqueductal" Examples
Periaqueductal refers to the area surrounding the aqueduct of Sylvius, which is a bundle of fibers that connects the midbrain to the pons in the brainstem. Here are five usage examples:
Example 1: Medical Research
The periaqueductal gray matter plays a crucial role in the regulation of pain processing in the central nervous system.
Example 2: Anatomy Lecture
The periaqueductal region is responsible for the transmission of auditory information from the brainstem to the thalamus.
Example 3: Neuroscience Journal
Studies have shown that the periaqueductal area is involved in the modulation of pain perception, with stimulation of this region leading to analgesic effects.
Example 4: Neurosurgery Textbook
The periaqueductal region is a critical target for stereotactic surgery in the treatment of certain movement disorders, such as essential tremor.
Example 5: Research Paper
Our findings suggest that the periaqueductal gray matter is a key player in the development of neuropathic pain, with altered gene expression profiles observed in this region in patients with chronic pain.
