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.
How many electrodes are used for a 12-lead ECG?
A 12-lead ECG uses a total of 10 electrodes. These include six chest (precordial) electrodes and four limb electrodes. The combination of these electrodes allows for the recording of 12 different electrical views (leads) of the heart's activity.
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.
Match each of Earth's properties to the observation it affects?
To know what properties go with what effects the choices for both will need to e given. Not knowing what the properties or effects are will not allow someone to know the answer.
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.
How do you reduce the earthing resistance?
By increasing the number, and depth of penetration, of earth electrodes. Chemical treatment of the soil in the vicinity of the earth electrodes can also be tried.
What are the Types of ion selective electrodes?
There are several types of ion-selective electrodes including glass membrane electrodes, liquid ion-exchange electrodes, solid-state ion-selective electrodes, and gas-sensing electrodes. Each type is designed to selectively detect and measure specific ions in a solution based on their electrochemical properties.
What has the author Robert J Fallon written?
Robert J. Fallon has written: 'Electrochemical properties of the palladium and palladium-hydrogen electrodes' -- subject(s): Palladium Electrodes, Palladium-hydrogen
Why must two electrodes be used to make an electrical measurement such as pH?
Two electrodes are required to make an electrical measurement, such as pH, because a potential difference is created between the electrodes when they are in contact with the solution being measured. The potential difference is then used to calculate the pH of the solution based on the known properties of the electrodes and the solution.
Why is copper used in the contruction of electrodes?
Copper is used in the construction of electrodes because it is a good conductor of electricity, corrosion resistant, and malleable. These properties make it ideal for carrying electrical current and withstanding the chemical reactions that occur during electrode processes.
What is earth physical properties?
Earth's physical properties are:Water,Dust,Rock,Air,and Iron
Why waveform of electromyogram is irregular?
Shape varies with:- electrodes used- location with respect to muscle fiber- electromechanical properties of muscle & connective tissue- recording equipment

What are depth electrodes?
They are electrodes surgically-implanted into the brain
What is an earth pit?
An 'earth pit', is a pit in which connection is made between the earthing (grounding) electrodes that have been hammered into (or laid into) the soil, and the earthing conductor that connects the electrical installation to those earthing electrodes.
What are some physical properties of the earth that start with D?
Depth, density, and dynamical ellipticity are physical properties of Earth.
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.
