PGO Spikes: The Brain’s Hidden Dream Signals
Introduction and Definition of PGO Spikes The term PGO spikes is an acronym derived from the anatomical structures involved in their generation and propagation: the Pons, the Lateral Geniculate Nucleus (LGN), and the Occipital Cortex. These electrophysiological phenomena represent highly characteristic, high-amplitude, transient electrical peaks documented primarily through electroencephalography (EEG) and electrooculography (EOG) during specific […]
Pontine Sleep: The REM Gatekeeper of Your Dreaming Mind
Introduction to Pontine Sleep Pontine Sleep, often synonymously referred to in basic neuroscience literature as the state of sleep marked by the existence of Ponto-Geniculo-Occipital (PGO) spikes, constitutes a critical and highly active phase of the sleep cycle. This phenomenon is fundamentally intertwined with Rapid Eye Movement (REM) sleep, commonly known as dreaming sleep, and […]
