The two hemispheres of the brain are linked by...
-
Corpus Callosum
-
Angular Gyrus
-
Cerebral Cortex
-
Brain Stem
Correct Answer
A. Corpus CallosumExplanation
The two hemispheres of the brain are connected and communicate with each other through a structure called the Corpus Callosum. This thick band of nerve fibers allows information and signals to be transmitted between the left and right hemispheres, enabling them to work together in various cognitive functions such as language processing, problem-solving, and coordination. Without the Corpus Callosum, the hemispheres would function independently, leading to a lack of integration and coordination in brain activities.Rate this question:

What is the connection between the language centers and the visual cortex?
-
Corpus Callosum
-
Angular Gyrus
-
Cerebral Cortex
-
Brain Stem
Correct Answer
A. Angular GyrusExplanation
The angular gyrus is the correct answer because it is a region in the brain that plays a crucial role in the connection between the language centers and the visual cortex. It is involved in the processing and integration of visual and auditory information, which is important for tasks such as reading and language comprehension. The angular gyrus helps in linking visual stimuli with their corresponding meaning, allowing for the understanding and interpretation of written language.Rate this question:

When the language center and visual cortex are damaged a person will suffer from...
-
Alexia and Agraphia
-
Split Brain
-
Seizures
Correct Answer
A. Alexia and AgraphiaExplanation
When the language center and visual cortex are damaged, a person will suffer from Alexia and Agraphia. Alexia refers to the inability to read, while Agraphia refers to the inability to write. These conditions occur when the areas of the brain responsible for language processing and visual perception are affected. The damage disrupts the person's ability to comprehend written words and express their thoughts through writing. This can significantly impact their communication skills and overall quality of life.Rate this question:

What is Alexia?
-
Inability to Read
-
Inability to Write
-
Inability to Speak
Correct Answer
A. Inability to ReadExplanation
Alexia refers to the inability to read. It is a condition where individuals have difficulty or are unable to understand written language, despite having normal vision and adequate intelligence. This can be caused by various factors such as brain damage, stroke, or neurological disorders. People with alexia may struggle to recognize letters, words, or sentences, and may have difficulty comprehending written information. This condition can significantly impact a person's ability to communicate and engage in activities that require reading skills.Rate this question:

What is Agraphia?
-
Inability to Read
-
Inability to Write
-
Inability to Speak
Correct Answer
A. Inability to WriteExplanation
Agraphia refers to the inability to write. It is a condition where a person loses the ability to write coherently or at all, despite having the physical ability to do so. This can be caused by various factors such as brain damage, stroke, or neurological disorders. Agraphia is different from the inability to read or speak, as it specifically pertains to the impairment in writing skills.Rate this question:

Split Brain Surgery is used to help reduce what?
-
Migraines
-
Nightmares
-
Epileptic Seizures
Correct Answer
A. Epileptic SeizuresExplanation
Split brain surgery is a procedure used to help reduce epileptic seizures. It involves severing the corpus callosum, the band of nerve fibers that connects the two hemispheres of the brain. This surgery is typically performed in cases where seizures cannot be controlled with medication. By severing the connection between the two hemispheres, the spread of abnormal electrical activity is limited, reducing the frequency and severity of seizures.Rate this question:

Each hemisphere's primary connections are to which side of the body?
-
Same
-
Opposite
Correct Answer
A. OppositeExplanation
The primary connections of each hemisphere are to the opposite side of the body. This is because the brain is cross-wired, meaning that the left hemisphere controls the right side of the body and the right hemisphere controls the left side of the body. This is why damage to one side of the brain can result in motor or sensory deficits on the opposite side of the body.Rate this question:
-
- 9.
In Split Brain patients which hemisphere is dominant?
-
Neither
-
Left
-
Right
Correct Answer
A. RightExplanation
In Split Brain patients, neither hemisphere is dominant. Split brain refers to a condition where the corpus callosum, the bundle of nerve fibers connecting the two hemispheres of the brain, is severed. This prevents communication between the two hemispheres, resulting in each hemisphere functioning independently. As a result, neither hemisphere can be considered dominant as they operate separately and have distinct functions.Rate this question:

What does the right brain specialize in?
-
Combining parts to make them whole
-
Logical Thinking
-
Analysis
-
Accuracy
Correct Answer
A. Combining parts to make them wholeExplanation
The right brain specializes in combining parts to make them whole. This refers to its ability to perceive and process information holistically, recognizing patterns and relationships between different elements. Unlike logical thinking, which is associated with the left brain, the right brain focuses on the big picture rather than breaking things down into smaller components. Analysis and accuracy, on the other hand, are more closely related to logical thinking and the left brain's analytical abilities.Rate this question:
