- balance and voluntary muscle function
- e.g. walking and lifting
- balance and voluntary muscle function
- medulla
- involuntary (automatic) body functions
- e.g. breathing and heart rate
- involuntary (automatic) body functions
- the complexity and delicacy of the brain makes investigating and treating brain disorders very difficult
- neuroscientists have been able to map certain regions of the brain by:
- studying patients with brain damage
- electrical stimulation
- MRI scanning
- neuroscientists have been able to map certain regions of the brain by:
- treating brain damage and disease
- e.g. lobotomy- cutting part of the cerebral cortex
- benefit; thought to alleviate the symptoms of some mental illnesses
- risks; bleeding in the brain, seizures, loss of brain function
- procedure was abandoned in the 1950s due to risks
- e.g. lobotomy- cutting part of the cerebral cortex
