The parietal lobe is more affected by sleep-deprivation than the frontal lobe. Given: The brain activity in the left prefrontal and parietal lobes of well-rested (RW) subjects and subjects sleep deprived for 24 hours (SD24) and 35 hours (SD35) is shown in the Graph 1: Graph 1: The brain activity in the left prefrontal and parietal lobes. Introduction: Magnetic resonance imaging (MRI) was used to measure the brain activity in different regions of the brain while conducting the likelihood ratio test (LTR) () and PLUS tests. The two regions of the brain, which showed the most significant differences in sleep-deprived (SD) and well-rested (RW) subjects were the left prefrontal lobe and the left parietal lobe.

34. Elon wants to find a way to prevent visitors to his factory and labs from remembering anything about what they've seen. He asks you to come up with a couple of ways of preventing the formation of declarative memories. Pretend you have no morals whatsoever and can be as invasive as you'd like. Which of the following techniques would be LEAST effective for this goal? a. Administering a CaMKIIa inhibitor on the hippocampus b. Destroying the hippocampus c. Destroying the prefrontal cortex d. Administering a NMDA receptor blocker in the hippocampus

In the past, aspiring London taxicab drivers underwent a rigorous education that required them to learn the location of about 25,000 streets in the city. The average posterior hippocampus of London cabbies, as revealed by magnetic resonance imaging, was larger than that in a comparable group of London bus operators, who follow a fixed route and so do not have to learn a detailed map of the city (Maguire et al. 2000). In addition, the more years of taxi driving, the larger the posterior hippocampus (Maguire et al. 2006). What does this research tell us about the interplay of the environment and genetics in the development of adaptive navigational skills in human beings? Please don't write from any online source.

MRI and PET scans have shown that patients at early stages of Alzheimer’s disease have medial temporal lobe atrophy and decreased neural activity in the parietal lobe and frontal lobe. Identify the symptoms of early onset Alzheimer’s disease that can result from these affected areas of the brain listed below. • Medial temporal lobe • Parietal lobe • Frontal lobe
