Q3 Creating a lesion in a specific area of the brain allows researchers to identify stimuli that activate a particular part of the brain. identify the probable function of a specific brain area. observe individual ion channels in the membranes of neurons. observe the activity of a particular part of the brain.
Q1 If you create a big lesion in the hippocampus area of a rat's brain the rat will have trouble with what functions
learning and memory
motor control
recognition of biological danger
regulation of hunger and thirst
Q2 A friend of yours who endured significant damage in the motor cortex in the right hemisphere is likely to
not be able to walk at all because he will be paralyzed from the waist down.
have some paralysis in the left side of his body.
not be able to understand anything you say to him.
have some paralysis on the right side of his body.

identify the probable function of a specific brain area.
observe individual ion channels in the membranes of neurons.
observe the activity of a particular part of the brain.
Q4 You just met the sibling of your roommate and discovered that even though the siblings are of the same sex they look exceptionally different. Which of the following is the best explanation of this situation?
They must be step-siblings, as genetic inheritance ensures that they share a significant number of genes.
Although they probably started out very similar genetically, their genotypes have changed during development to make them look very different.
Given the number of so many different combinations of genes possible during reproduction, it is very likely that the two siblings don't really share many gene alleles.
One has expressed only recessive genes, while the other has not.
Q5 Your friend cut her finger but the finger was reattached at the hospital. The doctors told your friend that even though she can't feel her finger right now, the feelings will come back after a few weeks because regrowth of axons is possible after injury in the peripheral Nervous System. What type of glia cells would be responsible for this process of regrowing axons?
Astrocytes
oligodendrocytes
Schwann cells
microglia
Q6 For some of the genes in the human genome either a mother's or father's version of a gene is expressed in a cell of the offspring, but not both. These genes are considered
imprinted
dominant
recessive.
an SNP
Q7 When neuroscientists use the stimulation techniques in research it is usually to
identify stimuli that can activate a particular part of the brain.
identify the function of a particular part of the brain.
observe individual ion channels in the membranes of neurons.
observe the activity of a particular part of the brain.
