Glutamate and aspartate
Glutamate and aspartate

These amino acids are the major stimulating neurotransmitter in the Central nervous system. They are found in the cerebral cortex, cerebellum and spinal cord. In response to the effects of glutamate in neurons increases the synthesis of nitric oxide. Excessive concentrations of glutamate can have a toxic effect, increasing the level of intracellular Ca2+,...

CT – computed tomography
CT – computed tomography

What is a CT or computed tomography? CT — computed tomography, non-invasive method to quickly obtain an image of the structures of the brain and skull. X-ray contrast agents help to identify brain tumors and abscesses. CT without contrast is used for rapid diagnosis of acute hemorrhage and various tough...

Lyumbalynaya puncture
Lyumbalynaya puncture

Lumbar puncture is used to assess intracranial pressure and composition of cerebrospinal fluid, administration of medicines or x-ray contrast agents for malegra-IFE. Relative contraindications include infection at the site of the proposed puncture, hemorrhagic diathesis, increased intracranial pressure and malformation Chiari type, impeding the current of the cerebrospinal fluid. When...

Myelography, EEG
Myelography, EEG

Myelography — a method of x-ray examination of the spinal cord by injection of contrast into the subarachnoid space through a lumbar puncture. MRI has replaced myelography in the diagnosis of pathological processes in the spinal canal, but if you can't perform an MRI continues to be used CT-myelography. Contraindications are the same as in...

MRI – Magnetic resonance imaging
MRI – Magnetic resonance imaging

What is MRI or Magnetic resonance imaging? MRI (Magnetic resonance imaging) produces images of neural structures with a higher resolution compared to CT. This distinction has the greatest clinical significance for the visualization of lesions of the brain and pathological processes in the posterior cranial fossa; the image of this...

neurotransmission
neurotransmission

Neurotransmission. The neuron generates and sends a nerve impulse in its axon, then transmits this signal across a synapse by releasing neurotransmitters that cause a reaction in another neuron or effector cell. The signal has a stimulating or inhibitory effects on the cell depending on the neurotransmitter...

tardive dyskinesia
tardive dyskinesia

Loss of dopaminergic neurons in the compact part of the black substance and other areas reduces the level of dopamine and metenkephalin, leading to increase activity of acetylcholine in the striatum. The increase in presynaptic release and synthesis of dopamine; increased sensitivity or density of postsynaptic dopamine receptor or a combination thereof....

The features of the cytological studies in women. That shows a smear for Cytology, when is the best time to carry out the procedure and how to prepare for it?
Electromyography and study the speed of the nerve impulse
Electromyography and study the speed of the nerve impulse

In cases where muscle weakness is difficult to address in clinical data to lose nerve, neuromuscular plexus or muscle, electrophysiological study allows to diagnose and to clarify the localization of the pathological process. Electromyography using a needle electrode recorded the electrical activity of muscles at rest and during...

Endorphins and enkephalins
Endorphins and enkephalins

Endorphins — polypeptides that activate many Central neurons. The cell body contains krupnomasshtabnye polypeptide called proopiomelanocortin, the precursor as-5 – and-endorphins. This polypeptide is transported along the axon and is cleaved into fragments; one of them is the endorphin contained in the neurons located in allowedprogram...

echoencephalography
echoencephalography

Echoencephalography may be performed directly at the bedside to detect hemorrhage and hydrocephalus in children under 2 years. The older children and adults replaced echoencephalography came CT. Cerebral angiography. The x-ray method based on the use of injectable x-ray contrast...
