Broca and Wernicke’s Aphasias
To prepare for this Assignment:
Review Chapter 9 of your textbook, focusing on language and aphasia.
Review this week’s Learning Resources about aphasia.
Choose ONE of the articles listed below and then download the full PDF from the Library (the articles have been pre-selected for you and cover topics such as neuroanatomy, neurophysiology, recovery of function, or novel treatments associated with Broca’s and/or Wernicke’s aphasia). You may choose your own article; however, it must be approved by your instructor before the assignment is due.
“The Effect of Speech Repetition Rate on Neural Activation in Healthy Adults: Implications for Treatment of Aphasia and Other Fluency Disorders”
OR
“Effect of choir activity in the rehabilitation of aphasia: a blind, randomised, controlled pilot Study”
OR
“Efficacy of intensive aphasia therapy in patients with chronic stroke: a randomised controlled trial”
OR
“Effect of Verb Network Strengthening Treatment (VNeST) in Persons With Aphasia: Extension and Replication of Previous Findings”
The Assignment (2–4 pages):
Suppose you just need to repeat out loud a sentence you just read or heard. Starting with written or heard information in the primary visual or primary auditory cortex, describe how that information is transferred to the parts of the language network that comprehend language. Next, describe how this information is transmitted to the parts of the brain that produce language.
Second, consider what happens when damage affects our ability to communicate. Briefly compare and contrast Broca and Wernicke’s aphasias in terms of the location of the damage and the effects on language and communication.
Finally, summarize your chosen article about aphasia. In your summary, discuss what the researchers did and how this research extends our understanding of this aphasia beyond what was described in the textbook. If the article was about recovery of function or a therapy, describe the therapy and how it might impact the quality of life for people with aphasia.
Support your Assignment with specific references to all resources used in its preparation. You should include in-text citations in the body of your Assignment as well as complete references in APA format at the end of your Assignment.

Brain & Behavior W2 Assignment
The pinna, the outside part of the ear, filters sound that gets amplified as it is conveyed to the auditory canal. The tympanic membrane, which separates the external ear from the middle, stretches across the end of the auditory canal. Sound vibration received at the eardrum conveys sound energy to ossicles (Garrett & Hough, 2022). Inside the cochlea, auditory stimulus changes and becomes neural impulses. To generate language, verbal input enters the auditory cortex and moves to Wernicke's zone to be interpreted. The transcribed input reaches this point over the angular gyrus and visual cortex (Garrett & Hough, 2022). When spoken feedback is necessary, Wernicke's part propels output to Broca's, where the verbal reaction is articulated. When the feedback needs to be inscribed, Wernicke's area drives the data to the angular gyrus rather than Broca's area, eventually creating an optical outline.
Language impairment in Broca's aphasia results from damaged Broca's area, which surrounds cortical and subcortical zones. Speech is not fluent and halting,
