A single unit is defined as a single, firing neuron whose spike potentials are distinctly isolated by a recording microelectrode. The ability to record signals from neurons is centered around the electric current flow through the neuron. - Answer-single unit recording? Are lesion techniques primarily anatomical or functional? - Answer-We can't use temporal resolution because weoften times do not have a before or after Be able to identify typical data presentations of the techniques listed ...

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...

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...
