Higher Functions of Cerebral Cortex Quiz

In a person with right handedness,

• the language function is in the left hemisphere.

• the face recognition function is in the right hemisphere.

• the left auditory cortex processes auditory stimuli from both ears.

• left hemisphere damage results in astereognosis.

• right hemisphere damage results in anomic aphasia.

Regarding cerebral hemisphere dominance:

• The left hemisphere processes the language function.

• The left auditory cortex integrates the auditory stimuli from left ear only.

• The right hemisphere processes face recognition.

• The left hemisphere involved in analytical functions.

• The right hemisphere is involved in the rational thoughts.

Damage to the following structures commonly leads to amnesia/memory loss:

• Precentral gyrus.

• Hippocampus.

• Mamillary body.

• Cerebellum.

• Occipital cortex.

Regarding learning and memory:

• During learning, the strength of neuronal connections increases.

• Working memory is formed by hippocampal long-term potentiation.

• Explicit memory is demonstrated by classic conditioning.

• Implicit memory is formed by past experiences.

• Emotional memory is stored in the amygdala.

During a conversation, Aiden listens to his friend Ethan speak. The mechanisms that occur for him to listen, understand and respond to Ethan is

• spoken words are perceived by the primary auditory cortex.

• spoken words heard are interpreted by the Wernicke area.

• the Wernicke's area sends impulses to the angular gyrus.

• arcuate fasciculus sends impulses to Broca area.

• muscle movement is initiated by the primary motor cortex.

Match the following types of memory with their descriptions.

• Memory of personal experiences.

• Procedural memory.

• Memory influenced by prior exposure.

• Episodic memory.

• Memory of skills and actions.

• Priming memory.

• Memory of facts and concepts.

• Semantic memory.

A 7-year-old boy tells his grandfather about his first day of school. He described the meal he had during the lunch break, that led to his diarrhoea. The MAIN type of memory recalled during his conversation above is

• semantic memory.

• episodic memory.

• procedural memory.

• priming memory.

A 65-year-old man had a history of ischemic stroke in his left temporal lobe. After the stroke, he had difficulty following the instructions given to him but was able to express words. The MOST likely brain area that was damaged is

• angular gyrus.

• Wernicke's area.

• Broca area.

• primary motor cortex.

A father tried to demonstrate to his son how to ride a bicycle. The MAIN type of memory recalled by the father is

• semantic memory.

• episodic memory.

• procedural memory.

• emotional conditioning/priming memory.
