Implantable electrodes are small devices that are surgically placed inside the body to stimulate targeted nerves or muscles. They are commonly used in medical treatments such as deep brain stimulation for neurological disorders, spinal cord stimulation for chronic pain management, and cochlear implants for hearing loss. These electrodes deliver controlled electrical impulses to specific areas to modulate their function and provide therapeutic benefits.

Type of electrodes used to electrically stimulate the brain?
Common types of electrodes used for electrical brain stimulation include intracranial electrodes (such as depth electrodes or grids), subdural electrodes, and transcranial electrodes. These electrodes are used in techniques like deep brain stimulation (DBS), electrocorticography (ECoG), and transcranial direct current stimulation (tDCS) to modify neural activity for therapeutic or research purposes.
Why do electrolysis of brine need inert electrodes?
Electrolysis of brine requires inert electrodes, such as platinum or graphite, to prevent the electrodes from reacting with the products of the electrolysis. Using inert electrodes ensures that the reactions at the electrodes are solely due to the electrolysis of the brine solution and do not introduce impurities or alter the chemical composition of the products.
What are the two pieces of difference metals that are in contact with electrolytes in a battery?
They are the two electrodes: anode and cathode.
What types of electrodes are used?
1. M.M.O.(MIXED METAL OXIDE) 2. MAGNESIUM ANODE3. ALUMINIUM ANODE4. ZINC ANODE5. PURE IRON ANODE6. PENCIL ANODE7. H.S.C.I. ANODE(high silicon cast iron)8. Pb-Ag ANODE9. PLATINUM ANODE (Pt-Ti & Pt-Nb)
Difference in a charge between two electrodes in a cell causes a ----between electrodes?
Potential difference.
How did the earlier version of the implantable cardioverter-defibrillator work?
implanted in the abdomen and required open-chest surgery to connect the electrodes to the left and right ventricles.
What is the CPT code for removal of a single lead implantable defibrillator pulse generator?
33243 Removal of single or dual chamber implantable defibrillator electrode(s); by thoracotomy33244Removal of single or dual chamber implantable defibrillator electrode(s); by transvenous extraction
What did the first pacemaker look like?
The first pacemaker, developed in 1958 by Dr. Paul Zoll, was a large, bulky device that resembled a suitcase. It used external electrodes placed on the patient's chest to deliver electrical impulses to stimulate the heart. The device was not implantable and required continuous power from an external source, making it quite cumbersome compared to modern pacemakers. Over time, pacemaker technology evolved significantly, leading to smaller, implantable devices that are now widely used.
What are depth electrodes?
They are electrodes surgically-implanted into the brain
Where was the implantable pacemaker invented?
It was invented at Cornell University by Wilson Greatbatch.
What is Pt electrodes?
Pt electrodes refer to electrodes that are made of platinum. These electrodes are commonly used in various electrochemical applications due to platinum's inert nature, high conductivity, and stability in corrosive environments. Pt electrodes are versatile and can be used in different setups such as in fuel cells, sensors, and electrophysiology experiments.
What the electrodes in the cochlear implant replace?
Electrodes placed inside the cochlear receive the decoded signals. The 22 electrodes allow a range of different pitches to be detected. The electrodes stimulate the hearing receptors.
