EEG records summed postsynaptic potentials generated mainly by cortical pyramidal neurons, captured using scalp electrodes placed according to the international 10–20 system, and reflects functional brain activity rather than structural anatomy ⚡. The lecture describes the major EEG waveforms, including alpha waves seen in relaxed wakefulness with eyes closed, beta waves associated with alertness and mental activity, theta waves seen in children and during drowsiness, and delta waves predominant in deep sleep and pathological conditions 🔥. Changes in EEG patterns during sleep stages, epilepsy, coma, encephalitis, and metabolic encephalopathies are discussed to highlight diagnostic relevance. Clinical correlations include EEG findings in generalized vs focal seizures, absence epilepsy with spike-and-wave discharges, and brain death evaluation. By integrating physiological basis, waveform interpretation, and applied clinical significance, this session builds strong conceptual clarity essential for MBBS theory exams, viva voce, MCQs, and neurological understanding ❤️✨. #Physiology #CNSPhysiology #Electroencephalography #EEG #Neurophysiology #BrainWaves #AlphaWaves #BetaWaves #ThetaWaves #DeltaWaves #SleepPhysiology #Epilepsy #ClinicalPhysiology #NeurologyBasics #MBBS #MBBS1stYear #MedicalEducation #LectureSeries #UniversityExams #VivaVoce #HighYield #ConceptualMedicine #DrBhanuPrakash #DrGBhanuPrakash
