Lesion Studies

GROSS DESCRIPTION: Exam of the specimen designated “left fallopian tube” reveals the presence of a fallopian tube measuring 6 cm in length and 2.3 cm in average diameter. Sectioning of the tube shows it to be

Experiments with psychiatric diagnosis these are considered experiments that people sometimes volunteer or sometimes they have an illness and they have to take medication in order to find out what is going on. They might be given strong medication so they see how they react or they want to see what happens in their heads. Sometimes they hook them up into machines and take a look at their brains to see how the medication is working. When this process is done, they go and they see what is wrong. Sometimes their brain shows where the damage is done. I have gone to see someone when they are doing this to their brain and well the picture is not that nice. You could see the brain and where the damage is done the brains are moving. It

23) The problem with relying on participants whose brains have been accidentally damaged in order to understand brain functioning is that

In the play “Scar Tissue” we see how the main characters is so involved in her emotional self due to the death of her daughter. Throughout the play, we see how characters are all having separate problems, but they all connect with each other at the end because of the difficult circumstances. The play takes place in the hospital when the main character Claudia is having a discussion with lee, her patient. Throughout that time, we see how Alma, Claudia’s daughter who is a ghost appears and tries to distract he from everything. Alma is a very difficult character to understand because of the way she acts and expresses herself. The behavior that Claudia has most of the time is because of her. Alma symbolizes, Claudia’s behavior that she expresses into the world and towards other.

* Second, research has shown that damage to incoming sensory pathways or the destruction of brain tissue can lead to neural reorganization.

a. Lesion method: disadvantages-no control over location of lesion, brain lesions resulting from trauma or

The documentary’s description of neuroplasticity of seizure patients represents the unknowing and negligent work ethic of modern day scientists and researchers alike. This is confirmed by the lack of treatment of these afflicted individuals who suffer a never ending siege daily with themselves, almost always certain that their pain will end but it is always to no avail.

• Imaging studies of the brain and spinal cord, such as an MRI or CT scan.

In classical neuroscience, there was the theory that the adult brain was considered fixed and inflexible; every part had a specific purpose and function and when it is damaged, cannot be replaced or repaired. Today experimental techniques suggest and embrace the recognition that the brain is plastic and can change itself with exercise and understanding whether you are an infant or an adult. It explains that the brain is constantly seeping out in various directions and is apparently able to respond to injury with a striking functional reorganization, and sometimes actually thinks itself into a new structure of body arrangement. Doidge also argues that plasticity can be good or bad based on the way a brain is used. For instance, on the wrong side individuals who watches pornography have deleterious part of their brain that makes them addictive to watching porn and

164). This non-invasive intervention uses electrodes that are placed on the scalp, to measure brain function (including brainwave pattens, auditory and visual feedback), which allows participants to observe their own brain function to enhance theor cognitive ability. For the most effective results participants were required complete a minimum of 1 to 2 sessions a week and for longer lasting improvements, at least 10 sessions a week. During each session, participants listened to sounds while playing a video game, they play the game by using only their brain. When their brain wave activity reaches the required criteria, they gain points (which acts as the reward in this appliction of operant conditioning). This type of brain training has shown to be effective as it has been used to treat mental illness, and improve cognitive ability, especially among older populations (Rabipour & Raz, 2012, p. 165).

For instance, testing reflexes, muscle tone, strength, being able to get up from a chair, then walk across the room, vision, sense of hearing, coordination and balance. Blood tests can help doctors rule out other possible causes of disorientation and memory loss, like thyroid disorders or the lack of vitamins. Pictures of the brain are now used to spot out visible distortions related to other conditions such as strokes, a trauma or tumors that may cause emotional changes. New items, used mainly in utmost medical centers or in clinical trials allow doctors to find certain brain changes caused by Alzheimer's. Magnetic Resonance Imaging or MRI uses radio waves and a magnetic field to make detailed pictures of the brain. MRI's are used to rid of other conditions that may account for or be added to emotional symptoms. Computerized Tomography, a CT scan creates cross-sectional pictures of the brain. It's used to rule out tumors, strokes and head traumas. Positron Emission Tomography or a PET scan is where a person is injected with a low-level radioactive tracer into a vein, which is a special type of glucose that shows overall activity in various brain areas. This can show which parts of your brain are not working properly. Under certain conditions, such as increasing dementia

A pathologist is a physician who studies body fluids and tissues, their area of study is Pathology. A pathologist may examine tissues, body fluids and other body parts removed during surgery.They usually help general care doctor make a diagnosis your health or medical problems that occurred.There are many different areas of pathology such as anatomic pathology, cytopathology, forensic pathology and molecular pathology, but pathologist is the ones who study it.

Some tools used for seeing the brain like positron emission tomography help experts see the rain functioning and learn more about the brain. This has enabled the

In the present scenario researchers are very much spotlighted on the neurobiological factors but no apposite consequence has cropped up. The

2. Functional brain mapping (scanning a person's brain while he or she is performing a certain physical task such as squeezing a ball, or looking at a particular type of picture) is helping researchers better understand how the brain works.
