Thank you In mammals, the _____ is the main “biological clock” that controls circadian rhythms by regulating the activity of other cells. It appears to synchronize our cycles to daily light conditions via a hormone called _____.1) cerebellum; acetylcholine2) ventromedial nucleus; serotonin3) orbitofrontal cortex; dopamine4) suprachiasmatic nucleus; melatonin Chris has been busy creating chapter quizzes for you, thinking hard about the right questions to ask and how to phrase them. While he is working, we would expect his brainwave pattern to show primarily _____ waves. When he finally gets a chance to relax and stop focusing on work (but before he falls asleep), we would expect his brainwave pattern to gradually shift to primarily _____ waves.1) beta; alpha2) theta; delta3) alpha; beta4) delta; theta When researchers study sleep using an EEG, they can tell when an individual has entered _____ sleep because they can observe sleep spindles and K complexes.1) Stage 1 non-REM2) REM3) Stages 3 & 4 non-REM (“slow-wave”)4) Stage 2 non-REM All of the following occur during REM sleep, EXCEPT:1) sexual arousal and activation of the reproductive system (regardless of sex).2) respiration rate and heart rate increase.3) eyes move rapidly back and forth horizontally.4) EEG measurements show primarily “slow-wave” activity, with mostly delta waves (1-3 Hz). With regards to the function of sleep, research suggests that:1) neural activity during REM and non-REM sleep promotes learning via consolidation and pruning of inaccurate connections.2) REM sleep may stimulate neural development during childhood.3) all of these options4) more cerebrospinal fluid (CSF) flows though the brain during sleep, which helps to flush away waste products. The network that allows the brain to maintain wakefulness consists of:1) forebrain arousal centers, including the basal forebrain and lateral hypothalamus.2) brainstem arousal centers, including the PPT, LDT, locus coeruleus, and raphe nuclei.3) neither brainstem nor forebrain arousal centers.4) both brainstem and forebrain arousal centers. PGO waves, which travel from the pons through the lateral geniculate nucleus to the occipital lobes, appear to play a key role in generating:1) both REM and non-REM sleep.2) REM sleep.3) non-REM sleep.4) waking up from sleep. The anterior cingulate cortex and the anterior insular cortex are core components of the _____ network. This brain network detects when significant stimuli require our attention, and it directs activity in other brain networks to promote awareness and activation.1) central executive2) cable news3) default mode4) salience Activity in our visual cortex doesn’t necessarily guarantee that we will be consciously aware of seeing something. Instead, research suggests that visual awareness requires activity in the:1) none of these options2) lateral prefrontal cortex only.3) posterior parietal cortex only.4) lateral prefrontal AND posterior parietal cortex. The experience of attention reflects changes in cortical activity: When you shift your attention, activity shifts and synchronizes between different groups of neurons in different parts of the cortex. This is at least partly due to modulations in the _____, which is the gateway for sensory information to reach the cortex (other than olfaction).1) thalamus2) basal ganglia3) nucleus accumbens4) hypothalamus Social Science Psychology PSYCH 130 Share QuestionEmailCopy link Comments (0)
