The Brain and Speech Areas

These flashcards cover key vocabulary and terms related to the brain and its speech areas, crucial for understanding the material in Instrumental Phonetics.

Cerebrum

The largest part of the brain, divided into left and right hemispheres and further divided into four lobes: frontal, parietal, occipital, and temporal.

Cerebellum

Located under the cerebrum, it plays a role in fine-tuning skilled motor activities by receiving input from various systems.

Brainstem

Includes the midbrain, pons, and medulla; controls vital life functions like breathing and heart rate, and relays messages between the brain and spinal cord.

Basal ganglia

Structures that receive motor information from the primary motor cortex and modify movements to ensure the successful execution of motor plans.

Thalamus

Acts as the main relay station for sensory information heading to the cerebral cortex.

Amygdala

Involved in processing emotions, storing memories, and is associated with the emotion center of the brain.

Broca’s Area

Located in the frontal lobe, crucial for speech production and language processing; damage can lead to Broca’s aphasia.

Wernicke’s Area

Found in the temporal lobe, essential for language comprehension; damage can result in Wernicke’s aphasia.

Arcuate Fasciculus

A bundle of nerve fibers that connects Broca’s and Wernicke’s areas, essential for coordinated and fluent speech.

Motor Cortex

Coordinates the movements required for speech, sending signals to speech muscles for sound production.

Auditory Cortex

Located in the temporal lobe, important for processing sounds and plays a role in monitoring and adjusting speech.

Angular Gyrus

Located at the parietal-temporal-occipital junction; involved in transforming written language into verbal form.

Supplementary Motor Area

Part of the frontal lobe involved in planning complex movements, including speech.
