Document Summary
Cerebral cortex- responsible for abstract thinking or higher forms of thinking (sets us apart from other mammals) Frontal lobes- at front of brain; tied to personality, hypothetical and creative thinking, thinking about the future, making judgements; last part of brain to fully develop (age 25) Motor cortex- voluntary movement; amount of area on the motor cortex does not correspond to the size of the body part (fine movement has the biggest area example: fingers for writing, tongue and lips for speaking and eating) Homunculus- map of motor or sensory cortex. Broca"s area- responsible for our ability to produce speech (left frontal lobe) Broca"s aphasia- affects someone"s ability to produce speech (they have problems with writing as well) Parietal lobes- located at top of brain. Contains somatosensory cortex- receives information about touch sensations (the area corresponds to the sensitivity of that body part not the size of the body part)
