1. 1) A person who is shot in the head and the bullet goes through the cerebral cortex in the parietal
lobe makes a lesion that results in:
a. Twitching of the arms
b. Difficulty recognizing faces
c. The inability to speak
d. An inability to mail a letter
e. Amnesia
Solution
Damage to the parietal lobe of cerebral cortex;
Answer is 'C': The inability to speak.
In mammalian brain, the parietal lobe is one of the four major lobes of the cerebral cortex. It is
positioned above the occipital lobe and behind the frontal lobe. The parietal lobe mainly
integrates sensory information including spatial sense, navigation; the sense of touch in the
somatosensory cortex and the dorsal stream of the visual system. The major sensory inputs from
the skin such as touch, temperature, and pain receptors, relay through the thalamus to the parietal
lobe. Several areas of parietal lobe are involved in language processing.
Damage to the parietal lobe may result in "Gerstmann's Syndrome." including right-left
confusion, difficulty with writing, calulations and produce disorders of language (aphasia) and
the inability to perceive objects normally.
Answer 'd'is also correct to some extent: An inability to mail a letter.
Damage to the parietal lobe result inability to focus visual attention. A person can’t produce
words from memory for writing and faces problems in reading because inability to recognise the
word.
However frontal lobe of cerebral cortex also plays a major role in flexible thinking process and
memory.
b. Difficulty recognizing faces: Related to temporal lobe of brain
e. Amnesia: Associated with damage to the hippocampus and related areas.
