Localised damage, electrical stimulation and brain imaging provide different evidence about those functions. Delicate tissue, nearby pathways and the consequences of damage make surgery difficult. Subject: Science · Area: The Human Body · Ages 15 to 16 Page: https://lightmysky.com/learn/science/the-brain-regions-and-the-evidence-for-what-they-do-mt_BA_DGCDic8 ## Ready when they can - Name major brain regions and state one function each contributes to. - Explain what localised damage, electrical stimulation and functional imaging can and cannot show about a region's function. - Explain surgical difficulty using delicate tissue, closely packed pathways, limited space for swelling and the consequences of damage. ## Lesson: How we mapped the working brain Neurons work in connected networks. The cerebrum contributes to thought and memory. The cerebellum helps coordinate movement and balance. The brainstem helps regulate breathing and heart rate. These parts work with other parts of the nervous system. Within the cerebrum, the frontal lobe supports planning and movement. The temporal lobe supports hearing and memory. The occipital lobe contributes to visual processing. The parietal lobe processes touch and spatial information. These are useful associations, but a function can involve several connected regions. A skill lost after localised damage can provide evidence that the area or affected connections contribute to that skill. Compare abilities before and after damage, note which remain, and consider other causes of change. One case cannot establish that a patch works alone or reveal its exact role. Similar damage locations can have different effects in different people. *(drawing: The change supports a link with vision. It does not show that vision depends only on this area.)* Electrical stimulation can produce movement or sensation, linking the area and its connections to a response. Structural scans locate damage. Functional MRI (fMRI) measures blood-oxygen changes related to activity during a task. Task-linked activity shows an association; it does not prove that the area is necessary or works alone. Compare evidence from several methods and people. Brain surgery must avoid delicate tissue, blood vessels and closely packed pathways. Damage can permanently affect speech, movement or other functions. The skull also limits room for swelling. Depending on the operation, surgeons may use scans and electrical mapping to locate functions near the planned route. Mapping helps guide treatment, but risks remain. **Recap.** Brain regions work in networks. Damage, stimulation and imaging give different evidence about their functions. Surgery must protect delicate tissue and nearby pathways. *Lesson, questions and flashcards written for this dataset about brain regions, evidence for their functions and surgical risks.* ## Practice 8 questions on this page, each with its working shown. ## Needs first - [The Reflex Arc and Synapses](https://lightmysky.com/learn/science/the-reflex-arc-and-synapses-mt_evlgCVxTnK) ## Optional connections - [Neurons & Brain Structure](https://lightmysky.com/learn/science/neurons-and-brain-structure-mt_okUMpHsV-P) ## Opens up - [Regional Anatomy of the Central Nervous System](https://lightmysky.com/learn/science/regional-anatomy-of-the-central-nervous-system-mt_S9f5cUS8NZ)
