Anxiety disorders are widespread mental health conditions that affect approximately one in five people. They are characterized by varying degrees of nervousness, apprehension and fear, typically associated with catastrophic ...
The hippocampus is a brain structure within the temporal lobe known to play a key role in memory and learning. The hippocampus contains neural networks that support what is known as declarative memory. This is the human ability ...
In recent years, neuroscientists have been trying to understand the neural underpinnings of social behaviors and cognition. Studies on animal species, including primates and rodents, have identified a number of brain regions ...
Aggression is a common behavior both among humans and other animals, which is known to be particularly important for defense, protection and survival. While psychologists and neuroscientists have been investigating aggression ...
Mice are among the animal species most employed in neuroscience studies, as they are mammals (i.e., their brain is in some ways similar to the human brain) and their genetics or behaviors can be easily manipulated in experimental ...
For decades, neuroscientists have been trying to understand the neural mechanisms underpinning different social behaviors, including aggression. Aggressive, violent, or confrontational behaviors are common among humans and ...
A team of researchers from Université Paris-Saclay and Université Paris Descartes has developed a nano-drug that has been found to reduce pain in rodents. In their paper published in the journal Science Advances, the group ...
Diseases such as tuberculosis, anthrax, and shigellosis—a severe food-borne illness—eventually could be treated with an entirely new and more-effective kind of antibiotic, thanks to a team of scientists led by Kenneth ...

(PhysOrg.com) -- Unlike members of other animal species, human females do not have obvious physical signs to show the opposite sex that they are ovulating. But research over the years have found subtle changes in women such ...
From the very first weeks of life, countless connections are forged between neurons to ensure the propagation of nerve signals. These connections gradually shape the final architecture of the brain, known as the connectome. ...

In biology, a species is:
There are many definitions of what kind of unit a species is (or should be). A common definition is that of a group of organisms capable of interbreeding and producing fertile offspring, and separated from other such groups with which interbreeding does not (normally) happen. Other definitions may focus on similarity of DNA or morphology. Some species are further subdivided into subspecies, and here also there is no close agreement on the criteria to be used.
