A participant in a study of music perception listens to music with electrodes attached to her scalp while data are collected on the activity of her brain. This technique is called
Electroencephalography (EEG)
Image projected to left visual field of a split brain person will be processed in the
Right visual cortex
Split brain research has illustrated which of the following
The left hemisphere of the brain is responsible for language in most people
Which of the following allows the examination of living brain tissue visually without performing surgery
computerized axial tomography
In extreme cases, surgically severing the corpus callosum is a treatment for which of the following conditions?
epilepsy
Professor Janeja is studying which brain regions are involved in learning to correctly navigate a maze task. She randomly assigns half of a group of mice to get a lesion in one area of the brain. The other half does not get a lesion. Based on the following graph, where in the brain is the most likely site of the lesion?
hippocampus
Which of the following is brain imaging technique that produces the most detailed picture of brain structure
magnetic resonance imaging (MRI)
In which of the following techniques do researchers inject a harmless, radioactive substance into a living human brain to examine activity
positron emission tomography (PET)
Metabolic activity in different areas of the brain can Best be visualized by means of
positron emission tomography (PET)
Which of the following provides information regarding brain function by monitoring the brain at work through metabolism of glucose
positron emission tomography (PET)
Dr. Naum is studying the function of the medial temporal lobe of the brain by examining the case study of J.S., an individual who incurred damage in this area during a motor vehicle accident. Dr. Naum administers a battery of tasks multiple times over the course of several weeks to assess J.S.'s cognitive abilities. The graph below shows J.S.'s performance on three different tasks. The bar on the left shows his accuracy forming new memories in a lab context, the middle bar shows his accuracy on a driving course, and the bar on the right shows his accuracy on a third task.
remembering events that occurred shortly before his accident
Dr. Frishkoff is studying how participants' brain activity changes when they read sentences in which the last word is either expected ("The pizza was too hot to eat") or unexpected ("The pizza was too hot to cry"). While participants are reading, Dr. Frishkoff measures their brain activity. The results of her experiment are shown below.
showed a negative-going peak in brain wave activity approximately 400 milliseconds after the unexpected word was presented that the participants did not show in response to the expected word
