Brainwaves
Disclaimer: These are not expert opinions but work of secondary research over the internet. 'Dimag ki batti jal gayi' can be taken in literal sense, afterall our brain is an electrochemical organ whose 10 billion neurons are capable of producing upto 10 watts of charge while communicating with each other. Neurons use electric pulse to transfer information from one part of the brain to other, so whenever neuron fires electric charge, a spike can be seen on EEG(electroencephalogram). The oscillation of spike creates brainwaves, in simple words, our brain uses brainwaves of electric charge to form communication among different parts of brain. Depending on the frequency and amplitude of the brainwaves, they are categorised in 5 types which are associated with different states of our mind. For example, if you are dead, frequency and amplitude of your brainwaves measured on EEG will be zero whereas if you are hyperactive, brainwaves will have high frequency and lower amplitudes....
