Question

sensation and perception The brain imaging technique involving injecting a radioactive tracer into the blood is FMR1. lesioning. ablation. PET scan. An electrode is placed in an orientation column that responds best to orientations of 45 adjacent column of cells will probably best respond to orientations of 5 degrees. 90 degrees. 40 degrees. 225 degrees. Ablation is a procedure in which a radioactive isotope is injected into the bloodstream and traced through the brain. electrodes on the scalp are used to measure changes in brain activity. a particular area of the brain is removed or destroyed. an electromagnetic pulse is used to temporarily disrupt brain activity. Object discrimination problem: Landmark discrimination problem temporal lobes; parietal lobes parietal lobes: occipital lobes parietal lobes; temporal lobes LGN; thalamus A researcher finds that damage to Area A of the brain results in the loss of Function A but not In another individual, damage to Area B results in the loss of Function B but not Function results are best described as a/an associative link. single dissociation. double dissociation. differential assessment. The principle that specific functions are served by specific conical areas is called conical magnification. the distribution principle. modular organization. haptic segmentation. An area in the called the temporal lobe; FFA occipital lobe; RBC Prosopagnosia is the difficulty recognizing faces. due to damage to the parietal lobe. is specialized to recognize faces. parietal lobe; 1AH parietal lobe; area 4H due to damage to the MT cortex. the inability to detect movement. Computers are better than humans at perceiving objects because computers can process information faster than humans. computers have higher storage capacity than humans. computers can more easily determine the reasons for changes in lightness. none of these; humans are better than computers al object perception.

Explanation / Answer

1. d. PET scan because

Positron Emission Tomography (PET) is a neuroimaging technique involving the injection of radioactive glucose into the bloodstream, tracking the blood flow to the brain and combining this date into a series of computer-generised colour-coded images of the level of activity in various brain areas while engages in different tasks.
