The Study Of Speech Movements

Jane is a 65-year-old -year woman resident of the service-learning center (Alderwood Manor), I was able to visit. Jane has a difficulty making sounds of the words she wants to say. For instance, she meant to say, “I want Honey's for snack” but what comes out from her mouth would sound like “I-want-huh-nee-oz-for-suh-nack”. Jane has a condition called Apraxia of speech (AS) associated with another neurogenic communication disorder (NCD) called dysarthria. This condition occurs when “the messages from the brain to the mouth are disrupted, and the person cannot move his or her lips or tongue to the right place to say sounds correctly, even though the muscles are not weak” (American Speech-Language-Hearing Association, 2016). Duffy (2005) notes that 41% of the 155 affected persons who had a primary speech pathology diagnosis of apraxia of speech had suffered a single stroke; lesions in the area of the left middle cerebral artery distribution were commonly associated with apraxia of speech. Recent studies, however, show that apraxia of speech cannot be attributed to a single lesion site since it could be subcortical and/or cortical in nature (Murdoch, 2013). Jane is primarily diagnosed with apraxia of speech, but it is also important to note

The date is June 6th, 1984, and American President Ronald Reagan stands solemnly before a massive stone monument on what he calls "a lonely, windswept point on the northern shore of France." On this historic day, the President of the United States stands solemnly before a small crowd of some of the bravest men living. The men assembled before him know these cliffs well. These are the Rangers who scaled the cliffs 40 years ago to do more than win the cliffs on the shores of Normandy. These are the Rangers who began the retaking of the entirety of Europe from Axis Control. That was 40 years ago, now only 90 of the original 225 sit before him now. All that can be heard are the crash of the waves on beach below and the occasional cry of a seagull

Due to this, it has been deemed difficult to determine which deficit is the consequence of which part of a lesion. To overcome this problem, other methods are being used to aid in the visualisation of memory processes in the healthy parts of the brain. These come in the form of functional neuroimaging studies using Positron Emission Tomography (PET) and Functional Magnetic Resonance Imaging (fMRI). These studies have allowed researchers to target specific memory processes using targeted psychological experiments. However, with all psychological experiments, there are limitations to using neuroimaging equipment. PET and fMRI attain their signals from local changes in blood flow or metabolism correlated with neural activity rather than from brain waves (or signals). The local vascular changes affect the distribution of an injected radionuclide (e.g. O15) in PET or magnetic properties that are blood-oxygen level dependent (BOLD) in fMRI. The indirect measure of neural activity limits the temporal and spatial fidelity of activations.

The short story “Speech Sounds” is a science fiction story written by Octavia Butler. This essay portrays a central theme that really opened my eyes as well as many others. This theme is to never take your ability to communicate for granted. Communication is a huge part of our culture and civilization. I never truly realized how important communication really was until reading this story. Without it, we cannot express our feelings in a correct manner. Not being able to connect with other individuals results in it being very hard to cooperate with others, causing chaos amongst society. In a short amount of time, the world would turn on each other causing mass amounts of violence. Likewise, this is similar to the story “Speech Sounds.” There are many takeaways one can have after reading this story.

The Functional magnetic resonance imaging (fMRI) is a functional neuroimaging procedure that used MRI technology to measure our brains activity through blood flow changes and our voxels.

Florence Kelley campaigns for stricter child labor law in the U.S., in her speech at the National American Woman Suffrage Association (N.A.W.S.A) in 1905, by using emotional appeals, anaphoras, and metonymy to apprehend the N.A.W.S.A attention to the unethical working conditions of children in the U.S. focusing on the state of Georgia creating a heavy hearted tone.

This quantitative quasi-experimental study will employ a single-factor ex-post facto design. Statistical Parametric Mapping (SPM) is a statistic technique that will be used to examine the differences in brain activity recorded functional neuroimging using the neuroimaging techniques (i.e., PET and MRI). The software created by the Wellcome Department of Imaging Neuroscience will be used to conduct this analysis (Daglish et al., 2008).

fMRI scans were performed by using a complex machine with massive specifications, named 4-T whole-body Varian/ Siemens imaging system. Before they start their imaging, the patient’s heart rate was monitored with a fiber-optic pulse oximeter and placed on their head was a radio frequency coil to capture a map of their brain. Each patient is then instructed to lie calmly, breathe through their nose, and allow themselves to focus on the script that the instructors were about to read. Each script would usually last them about 30 seconds. After the script is read, they are encouraged to recall a memory for about 60 seconds and once they start, so does their measurements of their heartbeats. The script is then repeated again after 120 seconds. This method is repeated 3 times.

Speech is not a simple process when it comes to brain functions. A person has to think about what he or she wants to say. Then, those thoughts must be translated into words. Then the brain must command the mouth and throat to form those words and transmit sound.

In the recording of Emily's practice speech, she states that learning English is important because this will allow her to go to a university. Considering that both of her parents are attending graduate school and Emily is thinking about higher education at such a young age suggests that her motivation level is exceptionally high. Her home country, Korea, supports educational success through the idea that education defines one's socioeconomic status, health, and level of independence (asiasociety.org). Considering that her parents are both attending graduate school, they may have limited time to help Emily develop strong English skills in reading and writing. In addition to this, they are not learning the same English vocabulary that Emily needs

Several new methods can improve temporal and spatial resolution in fMRI. A possible methodological change involves focusing on specific regions of interest and ignoring other areas (37), thus increasing temporal resolution by decreasing the number of voxels measured per slice. This method requires a more hypothesis driven approach to fMRI because of the inability to record from the entire brain. Using a staggered single trial design, where

In neuropsychology and behavioral neuroscience, multiple methods have been used to create relations between brain function and behavior in addition to studying how the brain is stimulated to produce action. Static and Dynamic imagery techniques of observation have been used over the years to map out brain regions and understand relationships between internal brain activity and external behavior. However, one brain study method has proven to be a groundbreaking process that has managed to create other derivative methods and increased human understanding of the effects of brain activity alterations. This method is known as Magnetic Resonance Imaging (MRI).

In the control group, the fMRI-LI laterality index was found to correlate significantly with CTT-1 (strong correlation with the percentile score) and with CTT-2 (moderate correlation with the percentile score).

Using measurements of repetition suppression with functional magnetic resonance imaging adaptation techniques, neuronal responses in the cerebral cortex of humans can be understood. Repetition suppression is the process whereby previous processing of stimuli reduces the activation that results from processing subsequent stimuli with it. Repetition suppression is linked to neuronal adaptation. Neuronal adaptation suggests that continuous repetition of a stimulus results in a decrease in the neuronal signal.

Both techniques focus on the effects certain things have on the brain. Some of the advantages for one technique is a disadvantage for the other. For fMRI it was found that a non-invasive recording was produced from the brain signals, this can prevent the patients from being exposed to radiation which can put them at risk. Yet this is a disadvantage for PET scans as they don’t have this and the patient can still be put at risk (Barnes, 2013). This essay also included some studies that had been conducted using these brain imaging techniques. Researchers have been able to learn a lot more about the regional blood flow in impaired brain regions, this is because of the PET scans that have been conducted on patients with specific lesions. An example of this would be an amnesic patient with medial temporal lobe lesion (Weiner, Schintra, Velicer, 2003). It has looked at what researchers can gain when using the brain imagining techniques and what they can teach us. It has focused on biological and cognitive behaviour in studies that has used the brain imaging techniques. This essay has looked at how cognitive tasks can help when observing the brain, and how fMRI was used in assessing brain activation from past events (Fukuda,
