Temporal Lobes Flashcards
What is the fundamental Hz of the human voice?
100-400Hz.
What is the mechanical basis of human sound production?
The vocal folds and glottis trap air from the lungs intermittently, and the vibrations form oscillatory waves of air pressure.
Which part of the anatomy is essential in producing different sounds?
The larynx.
What are formants?
Peaks of power modulated by the structure of the nasal sinuses and vocal tract.
Define phonemes.
The set of sounds we can make.
Define morphemes.
The smallest meaningful units of language.
Define syntax.
How we put words/phrases into order to be understood.
Children are born with categorical perception. What does this mean?
An ability to pick up the acoustic changes that signal boundaries between phonemes.
What is the Wada procedure?
A procedure used for studying the function of a single cerebral hemisphere in people without brain damage.
Name the six brain regions involved in speech and language.
Broca’s area.
Wernicke’s area.
Primary motor cortex.
Primary somatosensory cortex.
Primary auditory cortex.
Primary visual cortex.
Describe classic Broca’s aphasia.
Halting speech.
Disordered syntax and grammar.
Comprehension intact.
Describe Wernicke’s aphasia.
Fluent speech.
Adequate syntax and grammar.
Contrived or inappropriate words.
Comprehension not intact.
Name the seven different types of aphasia.
Broca’s.
Wernicke’s.
Conduction.
Global.
Transcortical motor area.
Transcortical sensory.
Anomic.
What is Landau-Kleffner syndrome?
Acquired epileptic aphasia.
Define prosody.
Stress and intonation.
Describe the theorised process of language production.
Wernicke’s area takes in sounds and processes them into words.
Information moves to Broca’s area where it becomes imbued with meaning.
Information is passed up to higher association areas.
Information moves back down to Broca’s area as acoustic patterns that are turned into vocalisations.
Which hemisphere are Broca’s and Wernicke’s areas located in?
Left hemisphere.
