The Evolution of Brain Imaging Technologies

Tracing the history of brain imaging reveals a journey of remarkable innovation and discovery. From the primitive methods of the past to today’s sophisticated technologies, this section outlines the evolution of brain imaging tools and their impact on neuroscience and psychology.

1. Early X-rays (1895): The discovery of X-rays by Wilhelm Conrad Roentgen opened the door to medical imaging, including the brain. However, early X-rays provided limited information about brain structures due to the similar radio-density of brain tissue and surrounding fluids.
2. Pneumoencephalography (1918–1970s): This technique involved replacing cerebrospinal fluid in the brain with air, gas, or iodine, to improve contrast in X-ray images. It was painful and had risks, but it allowed for better…
