Question

after brain damage, if a patient was able to name objects but was unable to reach out and interact with them properly, which part of the brain would likely be damaged?
ventral stream
somatosensory cortex
fusiform area
dorsal stream
question 54 (1 point)
bumps on the tongue called ________ contain numerous ________.
taste buds; mechanoreceptors
taste buds; papillae
papillae; taste buds
mechanoreceptors; taste buds

Explanation:

1. For the first question:

• The ventral stream is involved in object recognition (ability to name objects), while the dorsal stream is involved in the visual - guidance of action (ability to reach out and interact with objects). Since the patient can name objects (ventral stream likely intact) but can't interact properly (dorsal stream likely damaged).
• The somatosensory cortex is involved in processing touch, pressure, pain, etc., not directly in visual - guided action. The fusiform area is part of the ventral stream and is more related to object recognition (e.g., face recognition).

1. For the second question:

• Papillae are the bumps on the tongue. Taste buds are located within the papillae. Mechanoreceptors are involved in sensing mechanical stimuli (e.g., touch) and are not the main components within the tongue bumps in the context of taste.

Answer:

1. First question: Dorsal stream
2. Second question: papillae; taste buds
