Study Notes
Neural Basis of Language
- Language is more than just grammar; it encompasses cultural context, interactions, and varied communication styles (e.g., different ways of saying "please" in different cultures).
- Formal aspects of language include grammar, syntax, and word structure. Informal aspects involve semantics (meaning based on experience) and nonverbal communication cues.
- Language is a complex human function with innate and cultural influences.
- Emotional vocabulary differs across cultures, with some cultures emphasizing different emotional contexts.
Levels of Language
- Language comprehension involves both formal (syntax, grammar) and informal (semantics, meaning) levels.
- The left hemisphere dominates language's formal structure, whereas the right hemisphere is crucial for semantic and nonverbal aspects (e.g., tone).
- Extra-verbal meaning complements both formal and informal language.
Language Networks
- Two neural networks support language:
- Dorsal network connects inferior parietal and temporal lobes with prefrontal and frontal regions, supporting formal language aspects.
- Ventral network links temporal and frontal lobes, handling semantic or meaning-based language.
- Broca's area is associated with language production, and Wernicke's area (posterior temporal-parietal) with comprehension. These are interconnected.
- Damage to the arcuate fasciculus—a critical connection between Broca’s and Wernicke’s areas—often leads to problems in translating meaning into articulated speech.
- Inferior longitudinal and uncinate fasciculi are part of the ventral stream, but their specific role in semantic processing isn't as well understood.
- Dorsal stream (better understood) is connected to motor output (less plastic compared to semantic knowledge)
Dorsal Deficits (Articulatory Deficits)
- Articulatory deficits indicate problems translating meaning into motor programs for speech.
- Broca's area and the inferior frontal gyrus are crucial for producing specific sounds and words.
- Anarthria is an inability to sequentially activate muscles for speech; often due to ventral premotor cortex damage.
- Phonemic deficits involve difficulty sequencing phonemes within words, like inverting or omitting letters/sounds.
- Neologisms are novel, incorrect words, reflecting problems with semantic-motor translation.
- Neologistic jargon (severe cases) involves errors in every word of a sentence, making communication almost impossible.
- Damage to the arcuate fasciculus greatly affects speech production; larger damage correlates to more severe impairment.
Syntactical Processes
- Syntactical impairments include sentence simplifications, missing words, and grammatical errors (verb-subject order).
- Language errors in non-native speakers often arise from insufficient practice/connectivity.
Ventral Deficits (Semantic Deficits)
-
Semantic problems involve difficulties accessing or activating linked semantic networks.
-
Semantic knowledge involves interlinked concepts, forming complex networks.
-
Specific semantic problems can include:
- Anomias: Difficulty naming objects despite recognition.
- Semantic paraphasias: Naming objects with related but incorrect words.
- Verbal paraphasias: Naming objects with completely unconnected words.
-
Language processing often involves interconnected concepts; recalling “Newton” after reading about him is more likely than a month later.
-
Memory is essential for language as it involves a variety of concepts connected by semantic knowledge.
-
Damage affects semantic efficiency; concept accessibility is affected by recent activation.
Language Mapping
- Language mapping in the OR involves stimulating different brain regions during tasks like object naming.
- Stimulation can produce errors (e.g., phonetic paraphasia) identifying areas to avoid during brain surgery.
Assessing Language
- Assessing language involves both formal and informal communication techniques.
- Spontaneous conversation assesses a wide range of communication skills (pragmatics/tone/efficiency/informativity).
- Comprehension tests are standardized and offer structured assessments of understanding different language tasks.
- Standardized comprehension test: Start with simple tasks (e.g., "Touch the green token") and gradually increase complexity (e.g., "Touch the red square and green circle.").
- Assessments should consider patient needs and context, considering daily life tasks.
