Nouns denoting cognitive processes and contents.
Examples
- The discovery of the localisation principle led to a major shift in the field of physiology, as it challenged the long-held idea that the brain was a holistic entity.
- Broca's identification of the speech centre in the left frontal lobe is a classic example of the localisation principle in action.
- The localisation principle has been extensively studied in the context of the motor cortex, where specific areas are responsible for controlling different parts of the body.
- Researchers have used neuroimaging techniques to map the brain in unprecedented detail, further confirming the localisation principle as a fundamental aspect of brain function.
- Phineas Gage's tragic accident provided early evidence for the localisation principle, as his severe personality changes following a frontal lobe injury suggested a clear link between brain region and specific functions.
