Astrocytes
Neurons
Nociceptors

Example Question #1 : Sensory Structures & Processes
Robert experiences problems with language comprehension following a brain injury. He is most likely experiencing which of the following?
Conduction aphasia
Broca's aphasia
Global aphasia
Wernicke's aphasia
Agnosia
Wernicke's aphasia
"Wernicke's aphasia" is a receptive aphasia that results in problems with language comprehension. People with Wernicke's aphasia speak rapidly and do not make sense. They often do not have insight into their language difficulties. On the other hand, "Broca's aphasia" is an expressive aphasia that results in difficulty generating language. A person with Broca's aphasia produces slow speech with incorrect grammar, making it difficult to understand. “Global aphasia” includes symptoms of both Wernicke's and Broca's aphasias. A person with “conduction aphasia” has difficulties with verbal repetition. Last, “agnosia” involves problems processing sensory information.
