More than a century after Ivan Pavlov`s dog was conditioned to salivate when it heard the sound of a tone prior to receiving food, scientists have found neurons that are critical to how people and animals learn from experience.
Using a new imaging technique called Arc catFISH, researchers from the University of Washington have visualized individual [...]
