PSYCH 026: Electroencephalography in Psychiatry
If imaging reveals structure, electroencephalography (EEG) captures activity in real time. This chapter explores how electrical signals generated by neuronal populations can be recorded from the scalp, offering a dynamic view of brain function.
In this episode, we examine how EEG reflects synchronised activity across neural networks, producing patterns that can be analysed in terms of frequency, amplitude, and coherence. These rhythms - from slow delta waves to fast gamma activity - represent different states of brain function.
We explore how EEG is used clinically, particularly in epilepsy…
