Neuroendocrinology: The Rat That Defied Human Biology
Brattleboro Rat: A Model for Neuroendocrinology The Core Definition and Physiological Defect The Brattleboro rat (Rattus norvegicus) is a highly significant strain of laboratory rat, characterized fundamentally by a spontaneous genetic mutation that renders it incapable of producing the hormone Arginine Vasopressin (AVP), also known as Antidiuretic Hormone (ADH). This specific deficiency leads to a […]
FMRI MEASURES OF INTELLIGENCE
Introduction to fMRI and Intelligence Measurement Functional Magnetic Resonance Imaging, commonly known as fMRI, represents a transformative neuroscientific technique utilized to map and measure brain activity associated with specific cognitive tasks, including those underlying human intelligence. By leveraging changes in blood flow—specifically the ratio of oxygenated to deoxygenated hemoglobin, known as the Blood-Oxygenation-Level-Dependent (BOLD) signal—fMRI […]
