What is electricity used for in the brain?
Nerve cell signaling is an electro-chemical event. Thus, 'electricity' is used during cell-to-cell communication.

It has 5 watts.
Your brain uses as much power as a ten watt battery. -Helen Brosnan
Neurons do use electricity to communicate. When a neuron communicates, the usual sequence of events is: 1) binding of neurotransmitters to receptors on the cell body (soma) or… dendritic tree; 2) depending on the ligand/receptor in question, the membrane may become more or less permeable to certain ions (such as sodium, potassium, chloride etc), which changes the electrical potential difference across the cell membrane; 3) if the potential difference increases enough, then the cell will 'fire'; sending an 'action potential' (i.e., self-propagating electrical current across the membrane) from its axon hillock all the down to it's synaptic terminal, where it will then release it's neurotransmitters - and the process starts all over over again for recipient cells.
Without electricity, your brain wouldnÃ¢??t work. Electricity isresponsible for the nervous system sending signals to the brain,for your brain telling your muscles to move, …and for synapsesfiring.
Yes, it has a slight amount of electricity to power up a lightbulb
I believe that it's an electroencephalograph.
Yes. The discipline is called electroconvulsive therapy , and (under proper medical supervision) can be used to treat mental disorders such as major depression, bipolar disor…der, and schizophrenia.. The layman's term for it is electroshock therapy , but many practitioners avoid that term, considering it somewhat derogatory.
What method of studying the brain involves the use of electrodes placed on the scalp to detect and measure electrical activity of the brain?
No, they have been programmed by scientists. Every thing it does is on a thing called a micro chip, which has a lot of information on. ---------------------- --------…------------- Electronic things are programmed....they have a PCB that controls their operations with various other hardware stuff....(capacitors ; diode etc;) basically its all hardware..and the response is limited...all the work is done by electrical signals like brain but their area of action is limited ..thats what human brain is capable of...

cell body to the axon to dendrites
