Cerebral Cortex and Neuron revision

The cerebral cortex is...

• The outer layer of the brain that is 2-3cm thick

• Involved in complex mental abilities and language functions

• The outer layer of the brain that is 2-3mm thick

• Joined by a structure called the cerebral callosum

The cerebral cortex is divided into (a)   hemispheres.​ The ​ (b)   hemisphere controls the ​right side of the body and vice versa.

• two
• three
• four
• ten
• left
• top
• bottom
• right

Organize these options into the right categories.

Groups:

(a) Left hemisphere specialisatons

,

(b) Right hemisphere specialisatons

• Movement of right side of body

• Visual (spatial) thinking

• Maths problem solving

• Processes sensation on left side of body

• Creativity

• Language functions

• Movement of left side of body

• Processes sensation on right side of body

Wernicke's area

Broca's area

Broca's area is located in the Frontal Lobe in the left hemisphere. It controls...

• production of speech

• understanding language

• ability to read

• ability to pronounce words longer then 10 syllables

Wernicke's area is located in the Temporal Lobe in the left hemisphere. It controls...

• Speech production

• Comprehension (understanding) language

• Producing coherent sentences that make sense

• Pronouncing words clearly

Brian sustained a brain injury and now has difficulty processing certain types of sounds. He now perceives white spots in his vision (and did not experience this before his injury). What part/s of the brain has Brian damaged?

• Occipital lobe, temporal lobe

• Frontal lobe, parietal lobe

• Broca's area, Wernicke's area

• Occipital lobe, parietal lobe

A neuron is a specialised cell in the Nervous System. What do neurons do?

• Help the brain to grow to full size

• Carry messages from the brain to the body and vice versa

• Help people see

• Help people hear sounds
