2c. Structure of the Cortex and the Endocrine System Flashcards
Unit 2
Each brain hemisphere is divided into four lobes that are separated by:
Prominent fissures
The surface of the cortex has peaks called:
Gyri
The surface of the cortex has valleys called:
Sulci
Means the brain controls the other side of your body
Contralaterality
Involved with speaking, making plans, judgements, goal setting and controls personality, stability and behavior:
The Frontal Lobe
Who suffered damage to the frontal lobe?
Phineas Gage
Where is the lobotomy site?
The Frontal Lobe
Controls voluntary movements:
Motor Cortex
What is linked to the thalamus by basal ganglia?
Motor Cortex
Receives info about touch from sense organs
Somatosensory Cortex
Controls sensations of touch, pressure, temperature, and pain:
Parietal Lobe
Vision Center for processing symbols, angles. shapes, shadows, and movements:
Occipital Lobe
Hearing and speech center; contains olfactory area:
Temporal Lobe
What controls some intellectual and emotional activities
The Temporal Lobe
Where is the Auditory Cortex?
Above the ear
What does the Olfactory Area control?
Smell
What does F.P.O.T. stand for?
Frontal Lobe
Parietal Lobe
Occipital Lobe
Temporal Lobe
Not related to sensory or motor function but are areas where higher level processing occurs; covers 3/4 of the entire cortex:
Association Areas
What are the Association Areas insulated by?
Glial Cells
Controls movement:
Motor Cortex
Controls movement necessary for speech:
Broca’s Area in Left Frontal Lobe
Transforms visual representation into auditory code, concerned with written language, involved in reading silently and aloud:
Angular Gyrus
Receives written words as visual stimulation:
Visual Cortex
Involved in comprehension/interpreting auditory code:
Wernicke’s Area in Left Temporal Lobe
Impairment of language:
Aphasia
Where does Aphasia occur?
The left hemisphere
What causes Aphasia?
Damage to either Broca’s area (impaired speaking) or to Wernicke’s area (impaired understanding)
What is the brain sculpted by?
Genes and Experiences
The brain’s ability to modify itself after some type of injury or illness:
Plasticity
A vivid perception that a limb that has been removed/amputated is still present in the body and performing its normal functions.
Phantom Limb (Body Parts)
How many hemispheres is the brain divided into?
Two
Processes reading, writing, speaking, math, comprehension skills, and positive emotions
The Left Hemisphere
Responsible for facial recognition, music, spacial interpretation, creativity, and negative emotions:
The Right Hemisphere
