1. Why was Ms. Jensen worried about her son? 2. What is significant about teen’s frontal lobes? 3. What is the role of the frontal lobe? 4. What are some teenage behaviors that this could help to explain?
The intricate fabric of interconnected neurons that form the body’s ultimate control and information processing center Covers the brain’s lower level structures Divided into four lobes and two halves
Frontal Lobes Parietal Lobes Occipital Lobes Temporal Lobes
The long crevice that divides the cerebral cortex into left and right hemispheres This and other fissures in the brain create major divisions in the brain called lobes
The portion of the cerebral cortex lying just behind the forehead Is involved in advanced cognitive processing, planning, and judgment. Includes the motor cortex Damage? paralysis and personality change
The strip of brain tissue at the rear of the frontal lobes. Controls voluntary movement. Different parts of the cortex control different parts of the body.
Face Arms Hips Tongue Toes Fingers Lips
Parts of the body that are capable of more intricate movements, demand more brain tissue.(examples: hands, face)
The portion of the cerebral cortex lying on the top of the head and toward the rear. Includes the somatosensory cortex and general association areas used in processing information. Damage? trouble with sensory perception
The portion of the cerebral cortex lying at the back of the head. It includes the primary visual processing areas of the brain. Damage? - selective blindness, difficulty identifying color, difficulty recognizing moving objects, blindsight
Includes the auditory (hearing) areas of the brain. ◦ Auditory areas -> process sound, language comprehension ◦ facial recognition ◦ connected to emotional limbic system Damage? difficulty processing sounds, inability to recognize faces (Prosopagnosia), feelings of spirituality (temporal lobe epilepsy)Prosopagnosia
Location: Temporal Lobe - left hemisphere Function: interprets the words that we hear or read Damage: Wernicke’s Aphasia - impairment language comprehensionWernicke’s Aphasia Symptoms: speech sounds normal but makes no sense
Location: Frontal Lobe Function: Generates any words that we speak Damage: Broca’s Aphasia - able to comprehend speech but cannot express what they want to sayBroca’s Aphasia
Corpus callosum Corpus callosum Thick band of nerve fibers connecting the hemispheres ◦ It’s how the 2 hemispheres communicate ◦ Damage: disconnection between two sides of brain Right-brained vs. left- brained? OR
