What was the important finding by Fritsch and Hitzig in 1870 regarding the brain?

The significant finding by Fritsch and Hitzig in 1870 was their demonstration that electrical stimulation of the motor cortex could elicit movements in various parts of the body. This groundbreaking discovery was crucial in advancing the understanding of the localized functions within the brain. By applying electrical currents to specific areas of the motor cortex in animals, they observed reliable responses, indicating that particular regions of the cortex correspond to motor functions for specific muscles or muscle groups. This laid the foundation for future explorations into the relationship between brain function and movement, ultimately contributing to the mapping of the brain and our understanding of motor control. This finding was a pivotal moment in neuroscience, influencing later research on brain functionality and further investigations into brain regions responsible for various cognitive and motor tasks.
