SWS decreases and REM increases
As the night progresses
REM; stages 3 and 4
Nightmares occur during ____________ and night terrors usually occur during ___________
an increase in the firing rate of neurons in the raphe nuclei
As a part of an ongoing study on consciousness you decide to use modern imaging techniques to analyze the brain activity of participants during REM sleep. Based on previous studies, which of the following would you LEAST likely expect to see in these individuals during REM?
sleep talking
Which of the following conditions is NOT significantly associated with the deeper stages of sleep?
the rats would suffer from chronic insomnia
Imagine that we were to go in and damage the preoptic region of the hypothalamus in a group of rats. What would you expect to would happen to their overall sleep wake pattern?
the superior colliculi
All of the following aspects of the brain are thought to help us maintain a wakeful state EXCEPT
the locus coeruleus
the raphe nuclei of the brainstem
the reticular formation, in particular pathways from here to the basal forebrain

Analyzing details (the "trees") rather than the gestalt (the "forest") within a visual presentation.
Which of the following is usually NOT usually a right hemisphere dominant function?
the participant points to STONE WRONG

Point to MILE CORRECT
In an experiment with split brain patients in which the word "MILE" appears to the left of a fixation point and the word "STONE" appears to the right on a tachistoscope, how will the participant respond when asked to point with the left hand to what they've just seen?
Wernicke's area WRONG The arcuate fasciculusYou are presented with a case involving language deficits. After examining the patients, you conclude that the patient can speak fluently and appears to have no problems with auditory comprehension, but has significant issues when repeating sentences or even short phrases. Based on these results, which area of the brain would you most likely investigate for damage?Broca's aphasia; Wernicke's aphasiaIn the article "The Breakdown of Language" Luke was diagnosed with _________________ and Beth was diagnosed with ____________________Both Luke and Beth had strokes, but different types of strokesIn the chapter "The Breakdown of Language" what were the etiologies (i.e. causes) of the aphasia for Luke and Beth?dreaming only occurs during REM sleepWhich of the following statements about dreaming is FALSE?

Most likely Peter has which type of schizophrenia?an expressionless faceWhich of the following would be considered a negative symptom of a schizophrenia patient?overall shrinkage of the sulci of the brain WRONG a significant asymmetry in the size of the left vs the right hemispheres of the brain CORRECTImagine that you're examining the brain of a schizophrenic patient using an fMRI. Which of the following results would you LEAST likely expect to find? enlargement of the lateral ventricles lower levels of activation in the frontal lobes a smaller than average hippocampus overall shrinkage of the sulci of the brain a significant asymmetry in size of the left versus the right hemispheres of the brainschizophrenia is more common among first degree relatives of patients with schizophrenia than it is in more distant relativesFamily studies of schizophrenia reveal thatdopamine agonists; serotonin antagonists WRONG Dopamine antagonists; glutamate agonistsMost medications to used to reduce positive symptoms of schizophrenia act as __________________ while more recent developed medications focusing on negative symptoms have been devised to primarily work as _____________________the chromosomal abnormality found in a recent Swedish study was also found in all four sisters Hester performance on a majority of the neuropsychological measures was significantly lower than that of the other sisters tested. This suggests that her perfrontal cortex was more likely impaired by the disease than Myra.According to the reading "A 39 Year Follow-up of the Genain Quadruplets", which of the following statements is TRUE in regards to the Genain sisters?
