You’ve recently heard about a research lab that sells rats to other institutions. They’ve been able to genetically engineer 2 different strains of rats. Rats in one strain are born without an amygdala. Rats from the other strain have an enlarged, overly-active amygdala. You order some rats from each strain for your lab in order to see how they behave. First, in your own words, state what the amygdala does.

Next, come up with a situation you could put your rats in (that’s different than the ones mentioned in the online lectures), and outline at least one behavior you would expect to be different from the “no amygdala” rats compared with normal, unaltered rats, and at least one behavior you would expect to be different from the “overly-active amygdala” rats compared with normal, unaltered rats

the sun's light combined with the visible wavelenghts form what is called ultraviolet radiation, which are the long waves at the end of a visible light sprectrum.

it is a limiting nutrient limited by a single nutrient in the ecosystem, & the single goes very slow.

answer: andy garner, a 17-year-old who decided to become a human guinea pig in 1965 and go without sleep for 11 days. by the second day his eyes had already stopped focusing, and he lost the ability to identify objects by touch. by day three he was moody and uncoordinated and by the end he had trouble with short term memory and had even started hallucinating.

and a rare genetic mutation called fatal familial insomnia, where people can’t sleep at all, gets progressively worse over months or years and leads to dementia and death.

a devoted soccer fan died after staying awake 48 hours to watch the world cup, she said. ‘while his untimely death was due to a stroke, studies show chronically sleeping fewer than six hours a night increases stroke risk by 4 1/2 times compared with those getting a consistent seven to eight hours.'
