Spontaneous recognition of a novel object is a popular measure of exploratory behavior,
perception and recognition memory in rodent models. Because of its relative simplicity and …

Pathogen transmission is a major limit of social species. Social distancing, a behavioural-
based response to diseases, has been regularly reported in nature. However, the …

It has become increasingly clear that a larger brain can confer cognitive benefits. Yet not all
of the numerous aspects of cognition seem to be affected by brain size. Recent evidence …

Natural environment imposes many challenges to animals, which have to use cognitive
abilities to cope with and exploit it to enhance their fitness. Since zebrafish is a well …

The novel object recognition, or novel-object preference (NOP) test is employed to assess
recognition memory in a variety of organisms. The subject is exposed to two identical …

This study aims to establish a protocol for evaluating the object recognition memory and
object location tasks in zebrafish. We evaluated novel the object recognition memory and …

Quantitative abilities have been reported in a wide range of species, including fish. Recent
studies have shown that adult guppies (Poecilia reticulata) can spontaneously select the …

Adults, infants and non-human primates are thought to possess similar non-verbal numerical
systems, but there is considerable debate regarding whether all vertebrates share the same …

Motion illusion refers to a perception of motion that is absent or different in the physical
stimulus. These illusions are a powerful non-invasive tool for understanding the …

Zebrafish represents a very promising model to study memory function and impairment in
vertebrates. The one-trial memory test has proven to be a reliable method to assess memory …
