Q

______ it is a lobe that its main target is for visual information. Damage to any part of primary visual
cortex (posterior part) causes cortical blindness in the related part of the visual field. And a
tumor in the occipital lobe ordinarily evokes only simple sensations, such as flashes of light

Q

What are different functions located in each lobe divided based on functional areas namely: _____ , _____ , _______

A

sensory cortex, motor cortex, and association cortex.

17
Q

_______ It is a functional areas that is found in the occipital, temporal, and parietal lobes. It processes incoming
information from the sensory systems.

A

Sensory cortex

18
Q

The occipital lobe contains the _____

A

primary visual cortex

19
Q

The primary auditory cortex is located in the ________

A

temporal lobe

20
Q

The postcentral gyrus of the parietal lobe contains the _______ , which is the highest level of processing for information about touch, pain, position, and skin temperature.

A

primary somatosensory
cortex

21
Q

The precentral gyrus is the ________ that provide the highest
level of command for voluntary movements. The primary motor cortex is located in the ___________

A

motor area of the cortex : located in the precentral gyrus of the frontal lobe

22
Q

The __________ are areas located primarily in the frontal,
temporal, and inferior parietal lobes. Association are the areas for connecting and integrating
sensory and motor functions. For example, combining visual and auditory information which
allows us to see the world as an integrated whole rather than discrete bits.

A

association cortex
