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.
What are inert and active electrodes?
Inert electrodes simply serve as electrical conductors and are unchanged by the cell processes. Active electrodes change during the cell reactions. An example of inert electrodes is platinum in the electrolysis of water. The platinum remains unchanged and the water is split into hydrogen and oxygen. An example of active electrodes is in the electrolysis of copper sulfate solution with copper electrodes. The anode copper is converted into copper ions in the solution, and metallic copper builds up on the cathode. The term active electrode is also used in eeg measurement, here as the opposite to passive electrode. Electrodes are the pads attached to the skin to get readings, and active ones don't need a conductive paste to get a good signal.
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 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 are electrodes made of?
It varies. Electrodes can be made of iron, carbon, platinum or any number of electrical conductors.
Is there types of electrodes in Shielded Metal Arc Welding?
Probably more than there are types of metal. There are many electrodes manufactured just for welding steel and for welding ON steel. Some electrodes are made to weld steel and other metals (multi-purpose). Some electrodes are designed to protect steel from chemicals and corrosive elements and are used to CLAD or OVERLAY or BUTTER. Steel, stainless steel and some other metals are manufactured with different alloys and electrodes are made to match these. Some electrodes are made to join dissimilar metals, say steel to stainless steel or Monel. It is very important to use the correct electrode for the application at hand.

What are vacuum tubes made of?
Vacuum tubes are typically made of glass or metal. The glass or metal envelope contains electrodes and is evacuated to create a vacuum inside. The electrodes are made of elements like tungsten or molybdenum.
