Several misconceptions are present in the general knowledge of how our brains work and as portrayed in pop culture. Mention one of these misconceptions.
Step by step
Solved in 2 steps
- In PET scans, red areas are brain regions that are most active, while blue, yellow, and green areas are least active. Figure 13.24 shows PET scans of normal brain activity (left) and (right) of the brain of a person while using cocaine. The frontal lobes of the brain hemispheres are toward the top of the scans. Their neurons play major roles in reasoning and other intellectual functions. Looking at these scan images, how do you suppose cocaine may affect mental functioning?The expression "can't see the forest for the trees" implies an over-reliance on the parts/details of a problem instead of considering the whole. Based on what we covered in lecture, it might also describe someone who has an overactive relative to their parietal cortex; premotor cortex left hemisphere; right hemisphere right hemisphere; left hemisphere premotor cortex; parietal cortexAlzheimer's Disease Alzheimer's disease is a progressive neurodegenerative disorder that affects almost 50 million people worldwide. The cause of Alzheimer's disease is still not well understood. It is thought to be a combination of genetics, lifestyle, and environmental causes. It is also difficult to diagnose Alzheimer's disease during the initial stages of the disease as symptoms can be mistaken for normal ageing. Currently, there is no cure for the disease. Medication can help manage the symptoms but degeneration of brain tissue cannot be stopped or reversed. Currently, the medication that manages the symptoms of Alzheimer's disease is a type of cholinesterase inhibitor. In other words, the medication inhibits the function of cholinesterase and helps in brain functioning and memory. What is the function of cholinesterase in the synapse? How does a cholinesterase inhibitor work in a synapse? Explain how cholinesterase inhibitors are able to increase brain functioning and…
- Could you please mention/explain some limitations and extensions (three each) associated with the following claim and research question. Claim: Gene therapy can reverse ageing. Research question: How does the injection of BDNF in the brain through gene therapy help treat Alzheimer's disease in people over the age of 65? please asapThere are many ways that Alzheimer's Disease can be stopped, slowed, or treated. True FalseHistological and brain imaging methods can be used to detect or confirm Alzheimer’s disease. Select ALL that apply: Functional MRI imaging of neuronal activity during episodic memory tasks shows increased activity in the hippocampus. The sulci appear larger The gyri appear thicker The lateral ventricles are enlarged Functional imaging shows a decreased metabolic activity in the temporoparietal cortex at resting states indicating defects in episodic memories
- The processing, which allows the same kinds of information to be processed in different brain structures, is called: Stream segregation Serial processing Distributed processing Parallel processing Notice it says "allows the same kind of information"MRI and PET scans have shown that patients at early stages of Alzheimer’s disease have medial temporal lobe atrophy and decreased neural activity in the parietal lobe and frontal lobe. Identify the symptoms of early onset Alzheimer’s disease that can result from these affected areas of the brain listed below. • Medial temporal lobe • Parietal lobe • Frontal lobeAlzheimer's disease is a progressive neurological degenerative disorder that affects almost 50 million people worldwide. The cause of Alzheimer's disease is still not well understood. It is thought to be a combination of genetics, lifestyle, and environmental causes. It is also difficult to diagnose Alzheimer's disease during the initial stages of the disease as symptoms can be mistaken for normal aging. Currently, there is no cure for the disease. Medication can help manage the symptoms but degeneration of brain tissue cannot be stopped or reversed. One medication used to manage the symptoms of Alzheimer's disease is a cholinesterase inhibitor. The medication helps to improve brain functioning and memory. What is the function of cholinesterase in the synapse? How does a cholinesterase inhibitor work in a synapse? Explain the function of cholinesterase inhibitor in increasing brain functioning and memory
- imagine that you are a neurologist. A patient has come to you with a cognitive deficit in their ability to name objects. Describe a brain activity recording technique you would use (e.g., PET, fMRI) and the brain area you would focus on (e.g., occipital lobe, temporal lobe) to determine if they have brain damage in an area that is important for this ability. You must name and describe the specific recording technique.Should the Canadian government increase the funding for Alzheimer's research? Choose one of the following viewpoints to answer this question: social or economical Clearly state your position on this issue Give and explain two reasons to support your viewpoint. Use research based evidence to support each reason. IEach of these brightly colored sticky notes represents a piece of information that someone doesn’t want to forget. Although we are all forgetful sometimes, most people do not have trouble remembering things that are important or routine to us, such as our friend’s name or how to get to class. Our brain, the control center of the nervous system and the rest of the body, normally allows us to retain and recall information. But if the brain becomes damaged, a person may need to rely excessively on external reminders — like this wall of sticky notes — rather than being able to trust their own memory. That is if they are able to remember to write things down in the first place. One person having trouble with their memory is Rosa, who is 68 years old. Rosa has been having difficulty remembering where she has set down objects in her house and forgot about a few doctor’s appointments and lunches she planned with friends. Her family began to notice that she would sometimes not recall recent…
