Which of the following brain imaging techniques is the fastest (i.e., the best temporal resolution)? Select one: a. Electroencephalography (EEG) b. Positron Emission Topography (PET) c. Magnetic Resonance Imaging (MRI) d. Transcranial Magnetic Stimulation (TMS)
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…
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.
What is NOT a limitation of functional magnetic resonance imaging? Group of answer choices 1.The fMRI technique has poor resolution in comparison to other techniques. 2.Research using fMRI is more exploratory than hypothesis-based. 3.Many fMRI results are not stable across time and/or are due to chance. 4.Conclusions from fMRI results are often exaggerated and oversimplified.
