Document Summary
How scientists study the nervous system: examining autopsy tissue. When a person is dead, ineffective since they are unable to respond: testing the behaviour of patients with brain damage. Type of loss of function then suggests what the brain region did before it was damaged. Makes predictions about the activity of our brains during being awake or asleep. Measures the activity level of our brain. Predicts the functional effect of brain injuries. Event related potentials (erp): time locks eeg activity to know when events take place in the brain but not where (due to the skull attenuating electrical signals: animal studies. Include axial tomography (cat/ct)- detailed, 2d x-ray images of the brain and other organs, provides greater detail than regular x-rays. Can help us detect problems such as soft tissue injuries in tendons and ligaments and are faster/cost less in an emergency.
