Overall, rats live to forage and mate. Most rats are nocturnal, though the brown rat is often awake day or night. Rats usually stick together in groups called packs. New packs are formed when a male and female go off on their own and nest in an area that doesn't already contain a ...
And rats can dream. Not only do they run mazes when awake, scientists have learned that theyrun the same mazes in their sleep, possibly using an unconscious state to help learn travel routes. They alsodream of a desired future, like a tasty treat, brain studies suggest. ...
11/13/2014 - It's anyone's worst nightmare -- lying in bed, startled half awake in the middle of the night, feeling something jostling around in the bed sheets. Half-shut eyes start to spread wide open as paranoia and fear set in. That's when a squeaky chirp pierces the dead ...

When I got back to bed, Jennifer was snoring softly. I was wide awake, starring at the ceiling. I heard the distant sounds of little footsteps hurry, and I imagined the state of the kitchen in the morning. I’d need to get up early and clean it before she found out. I’d tell ...
Therefore, in the present study we used an oxygen telemetry system to record kidney oxygenation 1) continuously 2) in awake animals throughout the experiment, and 3) after at least one week of recovery from implantation14,15. A proposed link between hypoxia and initial renal changes within ...

Subsequent treatment of the whole body was made on day 4. Midazolam was injected intraperitoneally from day 1 to day 4. After 4 days of treatment, there was a wash-out phase of 3 days until the next sequence. We found a positive correlation between minutes awake and number of scratch ...
In the awake state, aged rats had markedly lower EEG power compared with young adult rats. Furthermore, aged rats were more susceptible to EEG burst suppression induced by isoflurane or propofol, providing evidence that the aged brain is more sensitive to anaesthetic drugs. The present findings ...
___ We know that, while awake, fresh memories are recorded by reinforcing (加强) connections between brain cells, but the memory processes that take place while we sleep have been unclear.Support is growing for a theory that sleep evolved so that connections between neurons (神经元) in the ...
