localisation of function L5

• What is the result of damage to Broca's and Wernicke's areas?

  It results in different types of aphasia.
• What does the term "localisation of function" refer to?

  It refers to specific areas of the brain being associated with specific cognitive processes.
• What is expressive aphasia?

  It is an impaired ability to produce language, usually caused by damage in Broca's area.
• What is receptive aphasia?

  It is an impaired ability to extract meaning from spoken or written words, usually due to damage in Wernicke's area.
• How do Broca's and Wernicke's areas contribute to language?

  Broca's area is involved in speech production, while Wernicke's area is involved in understanding language.
• What is the role of the motor cortex?

  The motor cortex is responsible for the generation of voluntary movements.
• Where is the motor cortex located?

  It is located along the precentral gyrus.
• What did Havasty et al. (1997) find regarding gender differences in language areas?

  They found that women have proportionally larger Broca's and Wernicke's areas than men.
• What is the function of the somatosensory cortex?

  It processes sensory information from the skin.
• Where is the somatosensory cortex located?

  It is located in the postcentral gyrus.
• What did Brokers et al. (2007) discover about Broca's aphasia?

  They showed damage in areas besides Broca's area in aphasic patients.
• What does damage to Broca's area usually result in?

  It usually results in temporary speech disruption.
• What is the location of Broca's area?

  Broca's area is located in the posterior part of the left frontal lobe.
• What is Wernicke's area responsible for?

  Wernicke's area is involved in understanding language.
• What happens when Wernicke's area is damaged?

  A person may be able to speak but be unable to understand language.
• How is visual information processed in the brain?

  A nerve impulse from the retina is transmitted to the thalamus, which relays it to the visual cortex in the occipital lobes.
• How does visual field information transfer to the brain?

  Input from the left visual field transfers to the visual cortex in the right hemisphere and vice versa.
• How is auditory information processed in the brain?

  Nerve impulses from the cochlea travel via the auditory nerve to the brainstem for basic decoding, then continue to the auditory cortex.
• What happens to sound after it reaches the auditory cortex?

  The sound is interpreted in the auditory cortex.
