- The nonvisual awareness of the body’s position and movements is called ____.A gymnast is able to maintain a steady posture while on a balance beam. In order to maintain balance, the gymnast would need to see the balance beam and determine where her feet are touching it. She would need to control the muscle contractions in her body to ensure she doesn’t fall off the beam. The regions of the brain numbered above that are involved directly in maintaining balance are Answer, Answer, Answer, and Answer. Record your answer in descending (highest to lowest) order.A person who had a left hemispherectomy (surgical removal of the left hemisphere of the brain) will likely struggle the most with which of the following? ANS acuity (in other words, their Weber fraction is large) Two-digit arithmetic (e.g., 57+21) Ratio-processing system (RPS) tests Object-tracking system tasks Abstraction counting principle
- Endoscopy refers to medical examination of the inside of a human body by means of inserting a lighted optical instrument through a body opening. Fiberscopes operate in the visible wavelengths and consist of two major components. One component consists of a bundle of fibers that illuminates the examined area, and the other component transmits the images of the examined area to the eye of the physician or to some display device. Investigate the design of fiberscopes or the fiber-optic endoscope, and discuss your findings in a brief report.The figure shown is a homunculus of the star-nosed mole. The star- nosed mole has 22 fleshy appendages around its nose called vibrissae. A single vibrissae can give the animal information about texture and location of objects its surroundings. Which of the following statements are incorrect? * (A) Cortical magnification in star-nosed mole Dorsal Anatomical proportions 11 11 Mouth Ventral Proportion of cortex devoted to body regions This homunculus depicts that vibrissae take up a huge proportion of association and motor cortex. The larger the cortical area involved, the more sensitive the body region is. There is a high proportion of peripheral sensory neurons in the whiskers of rats and cats. Smaller receptive fields on the skin will give a larger two-point discrimination distance.In which direction would an MRI scanner move to produce sequential images of the body in the frontal plane, and in which direction would an MRI scanner move to produce sequential images of the body in the Sagittarius plane
- The nervous system is responsible for the processes of movement preparation, execution and control. In order for this to occur sensory information needs to processed. The sensory receptors in the body include exteroceptors, interoceptors, and proprioceptors. Briefly discuss these three classes of sensory receptors (be sure to include the specific sensory information in each of these areas) and how this information will contribute to the preparation, execution, control and performance of a skill you are familiar with. **create as an inforgraphic**There is a situation or phenomenon we are exposed to in our life and many of us stop at it and start to think why this happened. For example, a person is exposed to the fall of something that was in his hand without feeling his fall and without will (voluntary muscle contraction) from him, and to clarify more, we may be in a standing position or walking quietly, and in a moment and without warning, the knee is bent without feeling and without our will, and this takes fractions of a second. Why it is physiologicallyimagine 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.
- Please find the answer to all four questions Single-unit recording has: Good spatial resolution but poor temporal resolution Poor spatial resolution but good temporal resolution Good spatial and temporal resolution Poor spatial and temporal resolution ------------------------------------------- Which of the following statement is false regarding visual agnostics Patients are not perceptually blind The ability to discriminate hue, brightness and acuity is intact Patients can recognize object using other sensory modalities such as touch, sound, and smell The impairment is due to general memory loss ------------------------------------------- In functional neuroimaging, we say a brain area is activated when: That brain regions is more active in the experimental task than in the control task That brain region is more active in the control task that in the experimental task The BOLD signal in that brain region is correlated with some variable of interest The BOLD signal in that…Explain how you might assess a patient for the following sensory experiences. a. Stimulation: b. Reception: c. Transmission–perception–reaction:Tactile acuity refers to the minimum separation required between two objects for the brain to perceive them as two separate points. The Two-Point Discrimination test is one method used to measure tactile acuity. A two-pronged instrument such as a bent paperclip is pressed at various locations on the body. The distance between the two ends is increased gradually until the person feels two distinct points. This distance is then measured. The less the distance that two points can be perceived separately, the higher the tactile acuity of that area. When comparing the tactile acuity of various body parts, what have you concluded about the number of receptors in the palm of your hand relative to the number of receptors on your shoulder? a. The tactile acuity for the palm is higher than for the shoulders. Therefore, more receptors are found on the palm than on the shoulders. b. The tactile acuity for the shoulders is higher than for the palm. Therefore, more receptors are found on the…
