C2. P5 Flashcards
What is the newest structure in the brain?
Cerebral cortex and cerebrum
How much does the cerebrum weight?
It makes up 80% of the brains total weight
Is the cerebrum made up of white matter or dark matter?
White matter
What is white matter?
Highly myelinated neurons and glial cells
Is the cerebral cortex made up of white matter or gray matter?
Gray matter
What is gray matter?
Unmyelinated neurons
Are there more neurons in the cerebral cortex or the limbic system?
The cerebral cortex contains 23 billion neurons (300 trillion connections), it is much more advanced
What is the purpose of the occipital lobe?
Processing visual sensory information
What is the route visual information takes?
The information is sent through the brainstem to the thalamus, who will route it to the primary visual cortex in the occipital lobe
What allows us to be conscious of visual information?
The processing of it in the PVC
What is the purpose of the temporal lobe?
Register sound
What is the primary auditory cortex?
Involved in processing sounds and pitch
What does Wernicke’s area allow us to do?
Allows us to comprehend spoken language
Wernicke’s area and PAC are close together, allowing….
The understanding of spoken language
Is Werneck’s area in the right or left temporal lobe?
Left temporal lobe
What links senses with memories?
The temporal lobe links sensory experience with memories
What is the parietal lobe involved in?
Body awareness, sensory integration, and spatial orientation
What is the Primary Somatosensory cortex and where is it?
Located at the front of the parental role, the PSC processes sensory information concerning touch, pressure, vibration, and pain
What is the Homunculus Organization strip?
A part of the brain where the body can be mapped
What places get the most space in the homunculus strip?
Places with lots of sensations, like the face
What is the parietal association area?
Integrates sound from the temporal lobe, visual information from the occipital lobe, and sensation from the somatosensory cortex
What helps us judge distance?
Parietal association area
What is the primary motor cortex?
A strip that maps the motor movements of the body
What two cortexes have a homunculus organization?
The primary motor cortex and primary somatosensory cortex
Where is Broca’s area located?
Within the left frontal lobe
What is Broca’s area?
A cluster of neurons that help us with spoken language production
What is the most advanced part of the brain?
Prefrontal cortex
What are executive functions?
The advanced cognitive functions that involve self regulation and metacognition
What part of the brain is responsible for critical abstract thinking, moral reasoning, and behavior?
Prefrontal cortex
What is metacognition?
The higher order skills involved in thinking about thinking
What are the two areas of executive functions?
Internal regulation and metacognitive skills
What are three parts of internal regulation?
Inhibiting actions and urges, emotional regulation, and self monitoring
What are 4 parts of metacognitive skills
Working memory, problem solving, planning and decision making, abstract and symbolic thought
What are association areas?
Integrates information across the brain from incoming sensory input located in the cerebral cortex
What allows us to anticipate future events and weigh consequences?
Association areas
What don’t association areas do?
Are not involved with the initial processing of sensory information and initiating movement
