Electroencephalography (EEG) Questions With Solutions Neurophysiological basis of EEG: • Single neuron activity is too small to be picked up by EEG • EEG reflects the summation of the synchronous activity of many neurons with similar spatial orientations • Cortical pyramidal neurons produce most of the EEG signal Neural basis of EEG: Pyramidal neurons are spatially aligned and perpendicular to the cortical surface. Thus, EEG represents mainly the postsynaptic potentials of ...

Electroencephalography (EEG) Questions and Answers 2023 What is an EEG (electroencephalograph)? Electroencephalography (EEG) is a method of detecting neural activity by placing electrodes on the scalp. EEG recorded at the scalp is non-invasive - however, it is also possible to record intra-cranial EEG by measuring activity directly at the exposed cortex. EEG is cheap and (relatively) easy to conduct. The temporal resolution of an EEG is great, but the spatial resolution is poor. What...

Electroencephalography (EEG) Questions With Solutions Who initially invented EEGs? Hans Berger detected the first EEG signal in 1924 with electrodes attached to the scalp of a human and reported the results in 1929. Berger initially studied medicine because he was convinced that there is "psychic energy", which might allow for telepathy. Berger also first described the alpha rhythm - when people closed their eyes, the electrical signal was not constant, but it varied with a ch...
