    Study Notes

    Neuro 11:1

    • The lecture is about cognitive and behavioral disorders caused by brain damage, focusing on how language and memory functions are organized in the brain.
    • Brain functions are organized by specific brain circuits.
    • The lecture will use brain systems and their breakdowns as the primary method of study.
    • Example of language disorders: aphasia.
    • Example of memory disorders: amnesia.
    • Textbook organization differs from the lecture method.
    • Textbook typically organizes content by lobe (frontal, temporal, etc.).
    • Lecture organization prioritizes sensory/motor functions, then higher-level processes.
    • Chapter 18 and 19 (asymmetry and plasticity) will be discussed next week with potentially three slides per topic.
    • Students should not be overwhelmed by the readings; the lecture will focus on key areas.
    • Oliver Sacks' work is recommended as a high-quality source for some topics.

    Monday and Next Monday Classes

    • Classes scheduled for Monday and next Monday are different than usual.
    • Makeup classes were scheduled for Monday, Tuesday, and Wednesday of the week.
    • This will impact the course schedule.
    • Wednesday is the day for the first test, covering neuroimaging, etiologies like stroke and traumatic brain injury.
    • Test will be held outside of class time (3 hours).
    • There is no class on Wednesday, makeup time will be used for the test.

    Additional Information

    • The test will have 50 multiple choice questions, identical format.
    • Students need to prepare and should use online or printed textbook resources.
    • Location of certification questions for the test: Dentistry Building, 4th floor.
    • Important note: Students are not expected to read all 100 pages of the textbook; the lecture will focus on key areas of the material.
    • Presentations should include a brief context.
    • Presentations should focus on the topic of interest, within the framework of the class's topics.
    • Presentations should include 2-3 slides.

    Strategies for Presentations

    • Use current review articles or book chapters as a starting point for the presentations.
    • Provide context at the beginning of the presentation.
    • Include 2-3 slides, aiming to place the presentation within the context of the class material.
    • Use slides to illustrate the material.

    Brain Organization

    • The brain's cortex is divided into primary, secondary, and tertiary areas.
    • Primary areas: direct sensory input (thalamus) before descending to lower motor levels.
    • Secondary areas: interpret inputs (e.g., frequency recognition in auditory).
    • Tertiary areas: association cortex; combines info from different senses to create meaning.
    • Language functions are multimodal, involving multiple brain regions.

    Language Areas

    • Broca's area: in the frontal lobe; involved in language production.
    • Wernicke's area: in the temporal lobe; involved in language comprehension.
    • Arcuate fasciculus: important white matter pathway connecting comprehension and production areas.
    • Perisylvian regions: areas surrounding the Sylvian fissure, often involved in language.
    • Language areas rely on a network of brain areas, not just isolated regions.

    Disorders

    • There are various types of aphasia, both fluent and non-fluent.
    • Fluent aphasia: problems with semantics (meaning).
    • Non fluent aphasia: problems with production.
    • Aphasia can be classified as disorders of comprehension (fluent aphasias) or production (non-fluent aphasias).
    • Stroke is a frequent cause of aphasia (middle cerebral artery often affected).
    • Other causes include head injuries, infections (like herpes simplex encephalitis), and dementia like frontotemporal dementia.
    • Aphasia can affect different aspects of language (understanding, production, repetition).
