Q

Frontal Lobe

A

controls executive functions like concentration, thinking, problem solving and judgement: motivation, emotions, muscle strength, and behavior

47
Q

Parietal Lobe

A

controls feeling on the opposite side of the body, ability to understand spoken language, ability to express yourself with language, and processing sensory information such as texture, temperature, and position in space

48
Q

Occipital Lobe

A

controls sight and processing information from the eyes, such as recognizing images

49
