What was done
This narrative historical review summarizes over 35 years of research by Patricia Goldman-Rakic on frontal lobe organization. The paper details her experimental work evaluating the behavioral consequences of prefrontal lobectomy in rhesus monkeys across developmental stages from infancy into adulthood, as well as her investigations into the neural basis of working memory.
What was found
The abstract reports no numerical findings or statistical measures. It notes qualitatively that the functional impact of early prefrontal lesions depended on lesion location, age at injury (including prenatal stages), behaviors evaluated, and age at testing, and that her work established the prefrontal cortex as central to working memory and relevant to disorders such as schizophrenia.
Why it matters
Goldman-Rakic's discoveries helped overturn the mid-20th-century view that the frontal lobes were uninvolved in cognition, establishing the prefrontal cortex as a primary focus of modern cognitive neuroscience.
Limits
This is a non-systematic historical review containing no primary empirical data, meta-analysis, or quantitative effect sizes. The abstract provides no details on sample sizes or specific experimental parameters.
