Lashley's research

• P- the work of Karl Lashley (1950) suggests that higher cognitive functions, such as the processes involved in learning, are not localised but distributed in a more holistic way in the brain
• E- Lashley removed areas of the cortex (between 10 and 50%) in rats that were learning a maze. No area was proven to be more important than any other area in terms of the rats' ability to learn the maze.
• L- the process of learning seemed to require every part of the cortex, rather than being confined to a particular area. This seems to suggest that learning is too complex to be localised and requires the involvement of the whole brain
