A- 24 Reading Notes Modules 12 and 13
Older brain networks sustain basic life functions and enable memory, emotions, and basic drives
Frontal lobes are the portion of the cerebral cortex, lying just behind the forehead; involved in speaking and muscle movements and in making plans and judgments
Motor cortex is an area at the rear of the frontal lobes that controls voluntary movements
Test Yourself Question:
Our brain's
somatosensory
cortex registers and processes body touch and movement sensations. The
motor
cortex controls our voluntary movements.
Test Yourself Question
: Association areas are important because they are involved in higher mental functions.
Test Yourself Question:
The mind's two tracks are conscious and unconscious. Dual processing is the principle that information is often simultaneously processed on separate conscious and unconscious tracks.
Cerebral cortex is the intricate fabric of interconnected neural cells covering the cerebral hemispheres; the body's ultimate control and information-processing center
Parietal lobes are the portion of the cerebral cortex lying at the top of the head and toward the rear; receives sensory input for touch and body position
Somatosensory cortex is an area at the front of the parties lobes that registers and processes body touch and movement sensations
Ask Yourself Question:
What I have learned about the human brain enabling our mind has not affected how I view human nature because I am aware that the human brain is unique.
Test Yourself Question:
If we flash a red light to the right hemisphere of a right-handed person with a split brain, and flash a green light to the left hemisphere, each will observe it own color. The person would not be aware that the colors differ. The person will verbally report seeing the color green.
Ask Yourself Question:
Learning more about the brain's evolutionary history makes me feel more separate from other mammal s because humans have more abilities than an animal does.
Occipital lobes are the portion of the cerebral cortex lying at the back of the head; includes areas that receive information from the visual fields
Association areas are areas of the cerebral cortex that are not involved in primary motor or sensory functions; rather, they are involved in higher mental functions such as learning, remembering, thinking, and speaking
Test Yourself Question:
Reversing the right's foots motion is hard because the right limbs' opposed activities interfere with each other since both are controlled by the same (left) side of the brain.
It is easier to move the left foot opposite to the right hand because opposite sides of your brain control your left and right limbs, so the reversed motion causes less interference.
Sequential processing is processing one aspect of a problem at a time; generally used to process new information or to solve difficult problems
Test Yourself Question:
The area of the human brain that is most similar to that of less complex animals is the brainstem. The part of the human brain that distinguishes us most from less complex animals is the cerebral cortex
Temporal bones are the portion of the cerebral cortex lying roughly above the ears; includes the auditory ears, each receiving information primarily from the opposite ear
Plasticity is the brain's ability to change, especially during childhood, by reorganizing after damage or by building new pathways based on experience
Cognitive neuroscience is the interdisciplinary study of the brain activity linked with cognition
Test Yourself Question:
Those working int he interdisciplinary field called
cognitive neuroscience
study the brain activity associated with the mental processes of perception, thinking, memory, and languages.
Neurogenesis is the formation of new neurons
Ask Yourself Question:
Before reading this I was not aware that we only use around 10 percent of our brain. Learning about the functions helped me understand the functioning of our brain.
Consciousness is our subjective awareness of ourselves and our environment
Parallel processing is processing many aspects of a problem simultaneously; generally used to process well-learned information or to solve easy problems
Ask Yourself Question:
An example of something I do on "automatic pilot" is picking my fingernails.
A corpus callosum is the large band of neural fibers connecting the two brain hemispheres and carrying messages between them
Split brain is a condition resulting from surgery that isolates the brain's two hemispheres by cutting the fibers connecting them
Dual processing is the principle that information is often simultaneously processes on separate conscious and unconscious tracks
Blindsight is a condition in which a person can respond to a visual stimulus without consciously experiencing it
Ask Yourself Question:
I believe it would be scary to have knowledge in which I was unaware of and couldn't verbally report but I was able to act on because I would not understand where all of my knowledge was coming from.
