central nervous system: Encyclopedia - Central nervous system

The central nervous system (CNS) represents the largest part of the nervous system. Together with the peripheral nervous system, it has a fundamental role in the control of behavior. Since the strong theoretical influence of cybernetics in the fifties, the CNS is conceived as a system devoted to information processing, where an appropriate motor output is computed as a response to a sensory input. Yet, many threads of research suggest that motor activity exists well before the maturation of the sensory systems and then, that the senses only influence behaviour without dictating it. This h ...

central nervous system: Encyclopedia - Brain

In animals, the brain, or encephalon (Greek for "in the head"), acts as the control center of the central nervous system. In most animals, the brain is located in the head close to the primary sensory apparatus and the mouth. While all vertebrate nervous systems have a brain, invertebrate nervous systems may have either a centralized brain or collections of individual ganglia. The brain is an extremely complex organ; for example, the human brain is a collection of 100 billion neurons, each linked with up to 25,000 others [1]. T ...

central nervous system: Encyclopedia - Pain

Pain is an unpleasant sensation which may be associated with actual or potential tissue damage and which may have physical and emotional components. According to the International Association for the Study of Pain (IASP), one should distinguish between pain and nociception. The term "pain" is a subjective experience that typically accompanies nociception, but can also arise without any stimulus. It includes the emotional response. Nociception, on the other hand, is a neurophysiological term and denotes specific activity in nerv ...

central nervous system: Encyclopedia - Pharmacology

Pharmacology (in Greek: pharmacon (φάρμακον) meaning drug, and logos (λόγος) meaning science) is the study of how chemical substances interact with living systems. If substances have medicinal properties, they are considered pharmaceuticals. The field encompasses drug composition and properties, interactions, toxicology, therapy, and medical applications and antipathogenic capabilities. The science is considered to have been invented by Arabic physicians in Baghdad during the Golden Age of Islam; phar ...

central nervous system: Encyclopedia - Cholinergic

A synapse is cholinergic if it uses acetylcholine as its neurotransmitter. The parasympathetic nervous system is entirely cholinergic. A cholinergic agent, also known as a parasympathomimetic is a chemical which functions to enhance the effects mediated by acetylcholine in the central nervous system, the peripheral nervous system, or both. These include the acetylcholine receptor agonists musca ...

central nervous system: Encyclopedia - Benserazide

Benserazide is an inhibitor of DOPA decarboxylase that does not enter the central nervous system. It is often given with L-DOPA (levodopa, 3,4-dihydroxy-L-phenylalanine) in the treatment of Parkinson's disease to prevent the conversion of L-DOPA to dopamine in the periphery, thereby increasing the amount that reaches the central nervous system and reducing the required dose. It has no antiparkinson actions when given alone. Other related archivesParkinson's disease, central nervous system, do

central nervous system: Encyclopedia - Argyll Robertson pupil

Argyll Robertson pupils are small, unequal, irregularly shaped pupils that constrict with accommodation but do not react normally to light. This means that while the eyes can focus on objects both near and far, the direct and consensual response to light are reduced or absent. These are usually, but not always caused by central nervous system complications of syphilis. Other related archivesaccommodation, central nervous system, pupils, syphilis

central nervous system: Encyclopedia - Catecholamine

Catecholamines are chemical compounds derived from the amino acid tyrosine that act as hormones or neurotransmitters. They are examples of phenethylamines. Catecholamines are soluble, and so they can circulate dissolved in blood. The most abundant catecholamines are epinephrine (adrenaline), norepinephrine (noradrenaline) and dopamine. They are produced mainly from the adrenal medulla and the postganglionic fibers of the sympathetic nervous system. Adrenaline acts as a neurotransmitter in the central nervous system and a ...

central nervous system: Encyclopedia - Acetylcholine

The chemical compound acetylcholine, often abbreviated as ACh, was the first neurotransmitter to be identified. It is a chemical transmitter in both the peripheral nervous system (PNS) and central nervous system (CNS) in many organisms including humans. Acetylcholine - Chemistry. Acetylcholine is an ester of acetic acid and choline with chemical formula CH3COOCH2CH2N+(CH3) ...

central nervous system: Encyclopedia - Autonomic ganglion

An autonomic ganglion is a collection of neuron cell bodies within the autonomic nervous system. Autonomic ganglion - Sympathetic ganglia. Ganglia of the sympathetic nervous system deliver information to the body about stress and impending danger, and evokes the familiar fight-or-flight response when activated. Autonomic ganglion - Sympathetic chain ganglia. The sympathetic chain ganglia are located just anterior to the spinal cord. Preganglionic nerves from the central n ...

central nervous system: Encyclopedia - Blood-brain barrier

The blood-brain barrier (BBB) is a membrane that controls the passage of substances from the blood into the central nervous system. It is a physical barrier between the blood vessels in the central nervous system, and most parts of the central nervous system itself, that stops many substances from traveling across it. Blood-brain barrier - History. The existence of such a barrier was first noticed in experiments by Paul Ehrlich in the late 19th century. Ehrlich was a bacteriologist who was studying s ...

central nervous system: Encyclopedia - Cerebellum

The cerebellum (Latin: "little brain") is a region of the brain that plays an important role in the integration of sensory perception and motor output. Many neural pathways link the cerebellum with the motor cortex—which sends information to the muscles causing them to move—and the spinocerebellar tract—which provides feedback on the position of the body in space (proprioception). The cerebellum integrates these two functions, using the constant feedback on body position to fine-tune motor movements. Because of this 'upda ...

central nervous system: Encyclopedia - Anticholinergic

An anticholinergic agent is a member of a class of pharmaceutical compounds which serve to reduce the effects mediated by acetylcholine in the central nervous system and peripheral nervous system. Anticholinergics are typically reversible competitive inhibitors of one of the two types of acetylcholine receptors, and are classified according to the receptors that are affected: antimuscarinic agents operate on the muscarinic acetylcholine receptors, and antinicotinic agents operate on the nicotinic acetylcholine receptors. ...

Vigabatrin is an anticonvulsant that inhibits the catabolism of GABA. It is an analog of GABA, but it is not a receptor agonist.[2] Vigabatrin - Mechanism of Action. Vigabatrin is an irreversible inhibitor of gamma-aminobutyric acid transaminase (GABA-T), the enzyme responsible for the catabolism of GABA, which increases the level of GABA in the synapses.^Including:

central nervous system: Encyclopedia II - Local anesthetic - Undesired effects

The conduction of electric impulses follows a similar mechanism in peripheral nerves, the central nervous system, and the heart. The effects of local anesthetics are therefore not specific for the signal conduction in peripheral nerves. Side effects on the central nervous system and the heart may be severe and potentially fatal. However, toxicity usually occurs only at blood plasma levels which are rarely reached if proper anesthetic techniques are adhered to. See also:
