    Study Notes

    Introduction to Behavioral Neuroscience - PSYC 211

    • Course lecture 18 of 24 covers language (Textbook Chapter 13)
    • Instructor: Jonathan Britt
    • Contact TA: [email protected]

    Speech Comprehension

    • Verbal behavior is lateralized in the brain
    • Language disturbances (comprehension and expression) typically occur after damage to the left side of the brain.
    • Left hemisphere is dominant for speech in 90% of the population (94% of right-handed people and 70% of left-handed people)

    Prosody: Rhythm, Tone, and Emphasis

    • Human speech has a regular rhythm and cadence
    • People emphasize words to clarify meaning
    • Pitch changes indicate phrasing and distinguish between questions and assertions
    • Prosody (rhythm, emphasis, and tone) conveys emotional state
    • Right hemisphere function for prosody; left hemisphere damage impacts language comprehension, but prosodic cues may still be understood.

    Recognition of People's Voices

    • People recognize familiar voices, even newborn infants
    • Voice recognition is independent of word comprehension.
    • People with left-hemisphere brain damage can still often recognize voices even without comprehending language
    • Phonagnosia is a disorder where people struggle to identify voices, resulting from damage to the right cerebral cortex (temporal lobe).

    Unfamiliar Metaphors

    • Attempts to understand unfamiliar metaphors strongly activate the right hemisphere
    • Left hemisphere typically needed to understand literal meaning of words
    • Right hemisphere processes metaphorical language

    Aphasia

    • Aphasia is a disturbance in understanding, repeating, or producing meaningful speech
    • Difficulty isn't due to simple sensory or motor deficits or lack of motivation
    • Deficit is isolated; the patient recognizes others attempting to communicate and is aware of surroundings
    • Most cases related to left cerebral hemisphere damage.

    Middle Cerebral Artery

    • Damage to this artery often leads to aphasia
    • Symptoms depend on the location of cell death

    Aphasia Types

    • Damage to the frontal lobe (anterior aphasia, motor aphasia, expressive aphasia, Broca's aphasia, non-fluent aphasia) impacts speaking & writing
    • Damage to sensory association cortex (posterior aphasia, sensory aphasia, receptive aphasia, Wernicke's aphasia, fluent aphasia) affects language understanding.

    Types of Aphasia (Diagram)

    • A flowchart displaying different types of aphasia based on fluency, comprehension, and repetition abilities

    Word Comprehension

    • Understanding the meaning of "DOG" involves multiple senses (vision, auditory, touch, olfaction, gustatory, motor).

    Association Cortex

    • Diagram highlighting different areas of the association cortex responsible for various aspects of comprehending and understanding the word "dog" (e.g., what it looks like, sounds like, feels like, smells like, tastes like, how it acts).

    Language Areas

    • Diagram showing the location of key language areas in the brain relative to comprehension and expression tasks for words (including Broca's area, Wernicke's area).

    Word Comprehension: Posterior Language Area

    • The posterior language area is critical for language comprehension
    • This area activates neurons throughout sensory association cortices, which store word meanings
    • Specific word activation leads to activity throughout sensory cortices (related to vision, hearing, touch, etc.)

    Word Comprehension: Transcortical Sensory Aphasia

    • Damage to the posterior language area results Transcortical Sensory Aphasia
    • Impaired comprehension of words and difficulty expressing thoughts; word repetition may occur but comprehension is limited
    • Reading, writing without understanding.

    Receptive Fluent Aphasia (Wernicke's Aphasia)

    • Audiovisual comprehension difficulty (e.g., inability to understand verbally presented words);
    • Unfettered fluency with little meaning.

    Byron's Road to Recovery

    • Overview of a patient’s experience recovering from Wernicke’s aphasia; early improvement prognosis is not accurate; significant progress is possible

    Language Perception Areas: Posterior Language Area

    • Diagram illustrating how language areas connect to the Posterior Language Area

    Language Perception Areas: Broca's Area

    • Diagram showcasing how different language areas directly connect to Broca's area

    Types of Aphasia (Diagram)

    • A second diagram illustrating different types of aphasia based on fluency, comprehension, and repetition.

    Conduction Aphasia

    • Characterized by inability to repeat words
    • Comprehension and fluent speech are otherwise fine
    • Damage to arcuate fasciculus which connects Wernicke's and Broca's area.

    Wernicke's Area

    • Sound recognition as spoken words, situated in the left temporal lobe of auditory association cortex
    • Key difference between hearing a sound and recognizing it as word (primary auditory cortex vs. Wernicke's Area)
    • Understanding word meaning is another stage (Posterior Language Area)

    Pure Word Deafness

    • Inability to understand or repeat spoken words, even if other auditory functions intact
    • Often caused by damage to Wernicke's area

    Pure Word Deafness

    • People can still hear fine (generally), respond to non-speech sounds (like a doorbell, phone) and read/write.
    • They struggle to understand speech and can't repeat or recognize words; some difficulty speaking.

    Wernicke's Aphasia

    • Damage around Wernicke’s and Posterior language area
    • Combination of transcortical sensory aphasia & pure word deafness
    • Difficulty comprehending language; speak fluently but words/sentences lack meaning
    • Prosody (intonation/emphasis) is often present, but speech conveys little meaning.
    • Spoken word recognition and understanding abilities are interwoven within Wernicke's area.

    Receptive Fluent Aphasia (Wernicke's Aphasia)

    • Clarifying the key difference between pure word deafness and more extensive Wernicke's aphasia.

    Disorders of Reading

    • Diagram illustrating comprehension and written word perception.

    Pure Alexia

    • Damage to visual word-form area (VWFA)
    • Inability to recognize written words, but still able to perform other tasks (e.g., write)
    • Visual word form area is located in the fusiform gyrus of the left hemisphere (with face perception being more dominant in the right hemisphere).

    Reading

    • Different types of reading impairments are explained and the brain regions involved are noted (e.g., visual w-f-a related to difficulties reading words).
    • Whole-word vs. phonetic reading pathways discussed
    • Different dyslexia types are characterized (Surface Dyslexia, Phonological Dyslexia), describing associated issues and brain regions involved
    • Overview of neural basis for dyslexia.

    Sight Reading

    • Discuss how the visual word form area is crucial for reading and differentiating written words.

    Reading (Diagram)

    • A model illustrating the different stages of reading comprehension and associated factors.

    Selective Disorders of Reading

    • Stroke patients can have narrow reading impairments (Direct Dyslexia), even if other tasks like speaking are fine, signifying specific damage to visual word perception areas.

    Reading

    • Key perceptual cues related to recognizing objects are discussed.

    Types of Aphasia (Diagram)

    • A final diagram summarizing different types of aphasia.

    Speech Production: Broca's Area

    • Role of Broca's area in speech production.

    Speech Production

    • Damage to Broca's area in the left inferior frontal lobe causes difficulties in verbal expression, leading to slow, labored, non-fluent speech and frustration.

    Broca's Aphasia

    • Broca's aphasia encompasses articulation problems, agrammatism, and anomia.
    • Articulation struggles relate to tongue, lip, jaw, and other speech organ movement (e.g., sequencing issues like lipstick → lickstip)
    • Agrammatism relates to difficulty with grammatical devices (e.g., verb endings and word order); largely using content words (nouns, verbs) without function words (e.g., a, the).
    • Anomia is the difficulty in finding appropriate words.

    Agrammatism

    • Difficulty comprehending and utilizing grammatical structures (e.g., verb endings, sentence order—man bit dog—).
    • Focus on understanding/comprehending speech.
    • Content words are used frequently, but function words (article, preposition, etc.) are sparse.

    Speech Production and Comprehension

    • Distinction between content words (nouns, verbs, etc.) and function words (prepositions, articles) and their importance for meaning and grammar structure, specifically relating to Broca's Aphasia.

    Anomic Aphasia

    • Difficulty finding the correct word to describe an object, action, or attribute.
    • Often seen with Broca's Aphasia.
    • While people with Anomic Aphasia usually understand what's being said, they have a hard time generating the words.
    • Circumlocution is one strategies used to express oneself.
