In the early 1960s, a young neuroscientist named Michael Gazzaniga walked into the lab of his mentor, Roger Sperry, at Caltech. Their question was deceptively simple: If you cut the corpus callosum—the massive bridge of nerve fibers connecting the brain’s two hemispheres—would the brain split into two independent minds? The answer, which Gazzaniga would spend the next six decades unraveling, became the foundation of modern cognitive neuroscience.
The left hemisphere sees: My right hand picked a chicken head. That makes sense. But why is my left hand holding a shovel? I don’t know about the snow scene. Neurociencia Cognitiva Gazzaniga.pdf
This is the story of that quest—a tale not just of split-brain patients, but of how we see, remember, speak, and believe we have a single, unified "self." In the early 1960s, a young neuroscientist named

Here is a detailed, story-like breakdown of the core concepts, history, and key experiments from Gazzaniga’s approach to cognitive neuroscience.
Cognitive neuroscience is the scientific field that studies the biological processes that underlie cognition. It focuses specifically on the neural connections in the brain which are involved in mental processes.
Whether you find the digital file or purchase the hardcover, remember that the goal is not merely to pass the exam. It is to understand that your sense of a unified "self" is a beautiful construction of neural circuits. As Gazzaniga famously wrote, "Everything we are is a consequence of the activity of our brain."
