	Collection of Cerebral Spinal Fluid. Small Animal Diagnostic and Treatment Techniques
		Spinal needles for use in small animals are available in 20 to 22 gauge and 1- 1/2 to 3- 1/2 inches in length.
		Spinal fluid is obtained from the subarachnoid space which is a shallow space.
		Continue to hold the hub of the spinal needle as spinal fluid is collected so the tip of the needle is not dislodged from the subarachnoid space.

	AD Diagnostic Patent (Site not responding. Last check: 2007-10-12)
		The protein composition of cerebral spinal fluid is largely derived from serum proteins which leak into the subarachnoid space through imperfections in the blood brain barrier, such as the area postrema, and perhaps across the richly vascular choroid plexus, through which cerebral spinal fluid is generated as an ultrafiltrate.
		By the present invention, it is preferable to photolabel a small 10 to 30 microliter aliquot of cerebral spinal fluid with radioactively-labeled photoaffinity probe (i.e., [.sup.32 P]2N.sub.3 ATP or [.sup.32 P]8N.sub.3 ATP) resulting in an approximate final concentration of 10 to 30.mu.M for detection of the Alzheimer's disease-specific 42,000M.sub.r protein.
		The cerebral spinal fluid from Alzheimer's disease patients was photolabeled and the protein fraction was precipitated by ammonium sulfate at 20 to 40% saturation.

	CSF Collection - Health Centers
		Cerebral spinal fluid (CSF) collection is a test to?sample and measure pressure?in?the fluid that surrounds the brain and spinal cord.
		Lumbar puncture with fluid collection may also be part of other procedures, particularly a myelogram (x-ray or CT scan after dye has been inserted into the CSF).
		CSF can be used to diagnose certain neurologic disorders, particularly infections (such as meningitis) and brain or spinal cord damage.

	Healthopedia.com - Spinal Tap (Lumbar Puncture, LP)
		A spinal tap is a procedure where a special needle is inserted through the vertebrae in the lower back and into the space that surrounds the spinal cord.
		A spinal tap can be performed with a person bending over while sitting in a chair, or lying down on his or her side with the knees drawn up close to the chest.
		Spinal headaches occur due to a change in cerebral spinal fluid pressure as a result of removing a sample for testing.

	Blood Brain Barrier CSF (Site not responding. Last check: 2007-10-12)
		Anatomy and Physiology of the Cerebral Capillary Endothelia
		The majority of the CSF is in the subarachnoid space, where the arachnoid membranes bridge the sulci of the brain, in the basal cisterns and around the spinal cord.
		CSF cushions the brain, regulates brain extracellular fluid, allows for distribution of neuroactive substances, and is the "sink" that collects the waste products produced by the brain.

	Improved cerebral circulation with trepanation
		Considering that blood and cerebral spinal fluid (CSF) represent ionic conductors with small internal polarization it is possible to presume that the changes in the active conductivity between the electrodes will correspond to the dynamics of blood content in the cranio-cerebral cavity.
		The translocations of CSF between the cavities of the cranium and of the spine have both a periodic (corresponding to respiration and waves of IIIrd order) and also a non-periodic (connected with slow changes in the blood volume in the cranial cavity) character.
		Since the speed of volume CSF translocations between the brain and the spine cavities is limited, rapid changes in the blood supply of the cranio-cerebral cavity are compensated for by re-redistribution between the CSF and the venous blood in the cranial cavity.

	Cerebrospinal fluid - Wikipedia, the free encyclopedia
		Cerebrospinal fluid (CSF), Liquor cerebrospinalis, is a clear bodily fluid that occupies the subarachnoid space in the brain (the space between the skull and the cerebral cortex—more specifically, between the arachnoid and pia layers of the meninges).
		The CSF formed by the choroid plexuses in the ventricles, circulates through the interventricular foramina into the third ventricle and then via the mesencephalic duct (cerebral aqueduct) into the fourth ventricle through two lateral apertures (foramina of Luschka) and one median aperture (foramen of Magendie).
		It is usually obtained by a procedure called lumbar puncture in an attempt to count the cells in the fluid and to detect the levels of protein and glucose.

	Spinal Roller Table
		Spinal injuries cause the joints of the spine to lock up and lose their ability to bend and twist normally.
		This helps to return flexibility, elasticity, and preservation to that all important disc space which protects the opening for the spinal nerve.
		Its ability to “iron out” a crooked spine with its soothing way of stretching the yellow elastic fibers is amazing physicians and therapists with positive results where ever it is used.

	NeuroBasics
		CSF is produced via plasma ultrafiltration from vascular endothelium through basement membrane and active transport across ependymal cells of choroid plexi.
		The middle cerebral artery--a large terminal branch of the internal carotid artery--gives rise to the choroid artery, supplying the choroid plexus of the lateral ventricles.
		Is especially abundant in the cerebral cortex (among the gyri and sulci...or in some species...the smooth surface) and the cerebellum.

		This is a test used to detect the presence of microorganisms (bacteria, viruses, and fungus) in the cerebrospinal fluid (CSF) causing infection.
		CSF is a clear fluid that circulates in the space surrounding the spinal cord.
		The CSF protects the brain and spinal cord from injury and physical shocks, and carries products of neurosecretions (chemicals released by the neural tissue), chemicals in the cells, and chemical changes in the cells.

	Spinal Headaches Information on Medicinenet.com
		A spinal headache can occur as a result of a procedure such as a spinal tap (lumbar puncture) or epidural block (such as that performed during a womans labor and delivery).
		The spinal headache often is described as "a headache like no other." Spinal headaches are much more severe when the person is in an upright position; they improve when the person lies down.
		Sometimes intravenous fluids (fluids administered into the veins) are given; other times the person is advised to drink a beverage high in caffeine.

	eMedicine - Lumbar Puncture : Article Excerpt by Gil Z Shlamovitz
		Lumbar puncture is a procedure that is often performed in the emergency department to obtain information about the cerebrospinal fluid (CSF).
		Although usually used for diagnostic purposes to rule out potential life-threatening conditions such as bacterial meningitis or subarachnoid hemorrhage, lumbar puncture is also sometimes performed for therapeutic reasons, such as the treatment of pseudotumor cerebri.
		CSF fluid analysis can also aid in the diagnosis of various other conditions, such as demyelinating diseases and carcinomatous meningitis.
