, Types of agnosia: Visual - ANSWER-Occipital lobe
Types of agnosia: Auditory - ANSWER-Temporal lobe (lateral + superior)
Types of agnosia: Tactile - ANSWER-Parietal lobe
Types of agnosia: Body parts and relationships - ANSWER-Parietal lobe (posterio-inferior)
Types of aphasia: Auditory receptive - ANSWER-Temporal lobe (Wernicke's area)
Types of aphasia: Expressive speaking - ANSWER-Inferior posterior frontal area (Broca's)
Types of aphasia: Visual receptive - ANSWER-Parietal-occiptal
Broca's aphasia - ANSWER-Expressive type of aphasia characterized by intact reading
comprehension, impaired writing skills, and using only nouns and verbs in speech
Broca area (frontal lobe) contains the motor cortex, which is associated with speech formation,
as well as decision making, problem solving, the ability to concentrate, and short-term memory
Which part of the brain contains the Wernicke's speech area? - ANSWER-Temporal lobe
The temporal lobe is responsible for perception and interpretation of sounds as well as
localizing their source. It contains the Wernicke speech area, which allows a person to
understand spoken and written language. It is also involved in the integration of behavior,
