Methods
To evaluate the immediate effects of sleep deprivation in all groups, we quantified the corticosterone blood levels, anxiety-like behavior and depressive-like behaviors immediately after Psd.
To determine the immediate effects of sleep deprivation, the researchers measured stress hormone levels in the blood and behaviours related to anxiety and depression in all groups right after REM sleep deprivation.
Introduction
Sleep deprivation can be produced by physical or psychological factors. In both cases, consequences on organic homeostasis involve disruptions in circadian rhythm, mental impairments, hormonal changes and other medical problems.
Lack of sleep can be caused by physical or mental factors. In both cases, it can disrupt the body’s normal balance by affecting the body’s natural sleep-wake cycle, mental problems, hormone changes, and other health issues.
Results
To assess anxiety-like behavior associated with Psd, we analyzed the spontaneous locomotion and motivational responses on the open-field maze and the elevated plus maze.
They tested signs of anxiety caused by sleep deprivation by observing how much the mice moved and how willing they were to explore in different maze tests.
Discussion
The inclusion of several platforms promotes the social interaction among the experimental subjects, which appears to reduce the stress associated with the PSD model.
Having multiple platforms allowed the mice to interact with each other, which seemed to reduce the stress caused by the sleep deprivation setup.
Future Directions
One future study could examine whether the effects of sleep deprivation on anxiety and depression are similar in humans. Research could also investigate whether increasing social interaction can reduce stress caused by sleep deprivation.
Difficult Material
I found it challenging to understand how specific numerical values from the behavioural tests, such as time spent in the open arms of the elevated plus maze or movement in the open-field test, were used to indicate levels of anxiety and depression, and how these results were compared between the control, 48-hour, and 96-hour sleep deprivation groups.

Discussion.
· Paste quoted text on the next line. Do not include quotation marks or a bullet mark:
Our data suggest that PSD generates differential anxiety- and depressive-like behaviors depending on individual sex.
· Write your translation on the next line:
The data showed that lack of sleep causes different levels of anxiety and depression depending on the individual’s sex.
Additional Future Directions:
· What future research do you think should follow up on this work?
Future research could explore the reasoning as to why sleep deprivation affects the levels of anxiety and depression differently in males and females. Additionally, future research could explore if these results apply to humans as well.
Difficult Material (from original poster or subsequent student):
· What did the previous poster state was difficult to understand? (please copy and paste their statement here):
I found it challenging to understand how specific numerical values from the behavioural tests, such as time spent in the open arms of the elevated plus maze or movement in the open-field test, were used to indicate levels of anxiety and depression, and how these results were compared between the control, 48-hour, and 96-hour sleep deprivation groups.
· Please try to explain the difficult materials to the original poster, as best as you can. (This is where you can help them understand what they found difficult.)
The numbers from the behavioral test helped us understand how the animals behaved. For example, an animal that does not move much could have higher levels of anxiety and depression. Different groups with different amounts of sleep deprivation were then compared with one another using these numbers.
New Difficult Material (according to you):
· What did you not understand about this paper, that someone else can help with? If you understood everything, then what did you find most challenging to understand?
I found it difficult to understand some of the visuals they used to present the data. For example, the graph in Figure 3, had asterisk and many additional lines that I did not understand the significance of.
