EEG measures the summed postsynaptic potentials of cortical pyramidal neurons. During sleep, these signals undergo characteristic changes in frequency and amplitude: Beta Waves (13–30 Hz):

Sleep is a fundamental, recurring state of consciousness essential for overall health and well-being. It differs from a coma as it is a reversible state from which a person can be easily aroused. A key tool in studying sleep is the . Introduced by Hans Berger, the EEG records the electrical activity of the cerebral cortex. By using EEG alongside other physiological measures, researchers and clinicians can decipher the different stages of sleep and their associated neural activities, providing a crucial window into this essential restorative process. eeg and sleep physiology ppt

For decades, sleep was considered a passive state of “brain rest.” However, with the advent of Electroencephalography (EEG), we now understand sleep as an active, dynamic, and highly structured physiological process. This article serves as a detailed companion to a PowerPoint presentation designed for medical students, sleep technicians, or neuroscience enthusiasts. We will dissect how the EEG machine captures the electrical symphony of the sleeping brain, the physiological changes that accompany each stage, and why understanding this is critical for diagnosing sleep disorders. EEG measures the summed postsynaptic potentials of cortical

EEG-based sleep monitoring is essential for identifying various conditions: Sleep Apnea Narcolepsy Parasomnias (Sleepwalking, Night Terrors) A key tool in studying sleep is the

Sleep EEGs are vital for diagnosing various disorders by tracking abnormal brain waves, breathing, and movement: Neurotech EEG Sleep Apnoea:
