The posterior cortex represents a critical neuroanatomical domain within the mammalian brain, fundamentally responsible for processing the vast majority of visual sensory input. Broadly defined, the term encompasses the entirety of the occipital cortex, situated at the caudal (rear) pole of the cerebrum. This definition is inclusive, extending beyond primary processing centers to include complex […]
Introduction and Definition of the Occipital Cortex The occipital cortex constitutes the entirety of the cerebral cortex located within the occipital lobe, positioned at the posterior pole of the human brain. Functionally, it serves as the primary processing center for visual information, translating raw sensory data received from the retina into coherent, recognizable images and […]
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 […]
