Which Parts Of The Brain Do What?

The transcript discusses the historical and modern understanding of brain function, starting with Broca's discovery of a lesion in the brain responsible for speech generation. It highlights the early attempts to map brain functions to specific areas and the limitations of these methods. The development of MRI technology revealed the complexity of brain activity, showing that mental tasks require coordinated efforts across various brain regions. Recent research combines lesion studies and brain scans to create more accurate maps of brain functions, although many mysteries remain.

Explain the difference between correlating brain parts with mental tasks and proving their function in those tasks.

What challenges remain in understanding why Broca's patient could only say 'tan'?
