Study Notes

Communication and Language

  • Animals communicate using various modalities, such as sounds or gestures
  • Human communication relies heavily on verbal language
  • Language is distinct from communication, encompassing arbitrary symbols unique to human populations
  • Language encompasses conventional signals and the rules for combining them
  • The intricate nature of language necessitates specialized brain regions

Language Definition

  • Language requires a sender who encodes a message and a receiver who decodes it
  • Encoding involves structuring the message linguistically
  • Decoding entails understanding the message's meaning

Hemispheric Dominance

  • The two cerebral hemispheres don't equally participate in all cognitive functions
  • The left hemisphere is predominantly responsible for language functions, in most people
  • Left hemisphere dominance in language is genetically determined
  • Although usually, the left hemisphere is dominant for language, in between 1-5% of right-handed people a lesion in the right hemisphere can lead to aphasia
  • The right hemisphere plays a role in processing aspects like short sentences and written language

Aphasia Syndromes

  • Aphasia signifies a language function disruption or loss
  • Symptoms often occur together, but the exact cause isn't always apparent
  • Aphasia commonly results from brain lesions, typically caused by strokes, but inflammatory conditions, tumors or head injuries can be involved as well
  • Broca's aphasia involves difficulty in language production, with retained comprehension
  • Wernicke's aphasia features fluent speech but lacks comprehension.
  • Other types include conduction aphasia and global aphasia, among others

Agrammatism vs. Paragrammatism

  • Agrammatism (Broca's aphasia) involves omitting function words and inflections, resulting in grammatically incorrect sentences
  • Paragrammatism (Wernicke's aphasia) features grammatically correct sentences but uses semantically inappropriate words (non-words, made-up words)

Models of Language Processing

  • Wernicke's area and Broca's area are interconnected by a pathway known as the arcuate fasciculus
  • The model suggests that the brain stores auditory representations of words in one area and motor representations in another; and there is a network/pathway that connects them together
  • The Wernicke Lichtheim Model proposed a system of interconnected areas, including stores of auditory and motor representations of words, connected by the arcuate fasciculus, to explain language processing

Specific Language Deficits (continued)

  • Transcortical motor aphasia preserves repetition but lacks spontaneous speech
  • Transcortical sensory aphasia is characterized by impaired comprehension but preserved repetition
  • Conduction aphasia, also known as word deafness, is characterized by preserved comprehension but impaired repetition of words
  • Anomic aphasia features difficulty in naming specific objects (lexical access retrieval deficits)
  • Global aphasia involves profound impairments in all language modalities (production and comprehension)

Classification of Aphasia

  • Classification of aphasia is often based on fluent vs non-fluent speech
  • Fluent aphasia includes Wernicke's aphasia, conduction aphasia while non-fluent aphasia covers Broca's aphasia, transcortical motor aphasia
  • It's important to appreciate that this classification doesn't fully capture the varied symptoms and complexities of language disorders
