Chapter 2: Brain Structures Flashcards
Brain Structures
What are the 6 Brain Orientations?
Anterior (rostral)
Posterior (caudal)
Superior (dorsal)
Inferior (ventral)
Medial
Lateral
Where is the Anterior?
front of head
Where is the Dorsal?
Above Head
Where is Ventral?
Below Head
Where is Lataral?
Side of Head
Where is Medial
Middle of Head?
Where is posterior?
Behind Head
What are the lobes?
Frontal Lobe
Parietal Lobe
Temporal Lobe
Occipital Lobe
What does the Frontal Lobe do?
Complex Thoughts
Planning
Control of Movement
Map of Bodies Muscles
what does the Parietal Lobe do?
Touch
Spatial Awareness
Map of the bodies SKIN surface
What does the Occipital Lobe do?
Vision
What does the Temporal Lobe Do?
Hearing + Object Memory
What are the three planes of the Brain?
Coronal Plane
Horizontal Plane
Sagital Plane
Coronal Plane?
Splits brain in half from ear to ear vertically
Horizontal Plane?
Splits brain Horizontally?
Sagital Plane?
Splits brain between eyes vertically
What is the brains outer layer called?
Cerebal Cortex
What are folds in the brains surface called?
Gyri
Why does the brain have wrinkles?
To Create more Surface Area
How does neuroscientific data help in cognitive psychology?
- Provides insights into the biological basis of
cognition - Localization of cognitive functions
oEx. When hippocampus is damaged, memory is
impaired - Mapping neural networks
oEx. Sensorimotor network (i.e., sensory cortex +
motor cortex) is responsible for movements
Reasons why its dangerous to consider mapping brain areas and cogntiive functions fool proof?
- The adaptability and resilience of the brain
o The brain can reorganize itself to form new neural
connections
o Reroute the cognitive function to undamaged area - Correlation ≠ causation
o Brain area X is related to cognitive function Y, but not the root - Complexity of neural networks
o One brain area contributes to multiple cognitive function
o Multiple brain areas contribute to one cognitive function - Individual difference
