The categories that have been developed to analyze human memory (short term memory, long term memory, working memory) have been applied to the study of animal memory, and some of the phenomena characteristic of human short term memory (e.g. the serial position effect) have been detected in animals, particularly monkeys. [56]
A lack of sleep is not only dangerous to the health of humans but it also puts the health of these animals at risk, no matter their shape, size or species. ... brain size and body mass are ...
This study also produced evidence that suggests vervet monkeys improve in their ability to classify different predators and produce alarm calls for each predator as they get older. Further research into this phenomenon has discovered that infant vervet monkeys produce alarm calls for a wider variety of species than adults.
Animal-assisted therapy can be an effective in treating the trauma for survivors of sexual assault. [89] The presence of dogs have been shown to improve communication between the survivor and the therapist and to decrease survivors' anxiety and fear-responses. [90] Animal-assisted therapy increases social interaction for those with the disorder ...
Zebrafish have also been used to test the medicinal benefits of certain psychoactive drugs, particularly how they can be used to treat mental health problems. [38] A study looking into the antidepressant properties of ketamine using zebrafish as subjects found that when exposed to small amounts of ketamine (2 mg/L), zebrafish displayed more ...
Sleep can follow a physiological or behavioral definition. In the physiological sense, sleep is a state characterized by reversible unconsciousness, special brainwave patterns, sporadic eye movement, loss of muscle tone (possibly with some exceptions; see below regarding the sleep of birds and of aquatic mammals), and a compensatory increase following deprivation of the state, this last known ...
One of the important questions in sleep research is clearly defining the sleep state. This problem arises because sleep was traditionally defined as a state of consciousness and not as a physiological state, [14] [15] thus there was no clear definition of what minimum set of events constitute sleep and distinguish it from other states of partial or no consciousness.
