Intracranial electrode grid for electrocorticography. Intracranial electroencephalography Purpose record electrical activity from the cerebral cortex.(invasive) Electrocorticography ( ECoG), or intracranial electroencephalography ( iEEG), is a type of History [ ] ECoG was pioneered in the early 1950s by Electrophysiological basis [ ] ECoG signals are composed of synchronized postsynaptic potentials ( Using depth electrodes, the Procedure [ ] The ECoG recording is performed from electrodes placed on the exposed cortex. In order to access the cortex, a surgeon must first perform a craniotomy, removing a part of the skull to expose the brain surface. This procedure may be performed either under DCES [ ] Direct cortical electrical stimulation (DCES), also known as The functions most commonly mapped through DCES are primary motor, primary sensory, and language. The patient must be alert and interactive for mapping procedures, though patient involvement varies with each mapping procedure. Language mapping may involve naming, reading aloud, repetition, and oral comprehension; somatosensory mapping requires that the patient describe sensations experienced across the face and extremities as the surgeon stimulates different cortical regions. Clinical applications [ ] Since its development in the 1950s, ECoG has been used to localize epileptogenic zones during presurgical planning, map out cortical functions, and to predict the success of epileptic surgical resectioning. ECoG offers ...

Overview What’s an EEG? An EEG (electroencephalogram) measures and records your brain’s electrical signals. During an EEG, a technician places small metal disks (electrodes) on your scalp. The electrodes attach to a machine that gives your healthcare provider information about your brain’s activity. Brain activity can help your provider diagnose and monitor conditions that affect your brain. Why is an EEG performed? Most commonly, healthcare providers use an EEG to check for seizure activity related to Healthcare providers may use an EEG during brain surgery or to test the brain activity of someone in a EEGs can also check the status of brain-related conditions such as: • • • Infections, including • EEGs help diagnose the causes of symptoms such as: • Confusion. • Fainting ( • • Seizures. Who performs an EEG? A specially trained EEG technician performs the procedure. You may have an EEG in an outpatient laboratory or inpatient per your healthcare provider’s order. Some EEG tests record your brain’s activity while you go about your usual activities with an ambulatory device. What are the different types of EEG tests? There are several types of EEG tests: • Routine EEG: Routine EEG scans take 23 minutes. Your EEG technologist may ask you to breathe differently or look at flashing lights during the procedure. • Prolonged EEG: A prolonged EEG test usually takes one hour and 15 minutes, but some types can last several days. A prolonged EEG gives your healthcare provider more in...

The brain determines and controls every action a body takes. It acts as the core of the human body. Every neuron that runs through the body is ultimately connected to the brain. The brain determines the chemicals that should be released and the reflexes during emergencies. Any defect in a small brain region shows severe effects on our body. It affects the regular functioning of the human body. An electroencephalogram (EEG) test is taken to record such problems. This article will look at EEG, why it is used, the side effects of taking an EEG, how to prepare ourselves before taking an EEG, and what exactly happens during an EEG. This article will cover everything that you need to know about EEG. Electroencephalogram (EEG) EEG is a diagnostic test; it measures the electrical impulses in the brain. This test detects abnormalities of the brain or electrical impulses in the brain. Connecting electrodes of small discs onto the scalp carry out this test. These electrodes measure the electrical reading of the brain caused by activities involving brain cells. These measured charges are amplified and appear as a graph on paper or computer screen, which the health care provider interprets. An EEG is taken for nearly 100 pages or computer screens. The health care provider pays special attention to the basic waveform and examines the brief burst of energies, responding to the flashing lights. This study also measures the electrical activity of your brain to stimulations like sound, touc...
