Feelings of pain and discomfort are crucial to the survival and evolution of animals, as they help to detect injuries or existential threats and pinpoint their location in the body. Pain signals are produced by nociceptors, ...
(Medical Xpress) -- We experience an interesting phenomenon when the contrast of an image flickers as it moves across our visual field – namely, an illusory reversal in the direction of motion. Moreover, this reverse-phi ...
Aging is a natural process that affects all living organisms, prompting gradual changes in their behavior and abilities. Past studies have highlighted several physiological factors that can contribute to aging, including ...
Research led by Peking University, China, has discovered a single type of retinal photoreceptor cell in Drosophila (fruit fly) is involved in both visual perception and circadian photoentrainment by co-releasing histamine ...
Drosophila, commonly known as fruit flies, have been the focus of numerous biomedical and neuroscientific studies, as they can be easily bred, examined and experimented on. Over the years, studies on Drosophila have led to ...
Researchers have completed the most advanced brain map to date, that of an insect, a landmark achievement in neuroscience that brings scientists closer to true understanding of the mechanism of thought.

Nematocera (includes Eudiptera) Brachycera
True flies are insects of the order Diptera (Greek: di = two, and pteron = wing), possessing a single pair of wings on the mesothorax and a pair of halteres, derived from the hind wings, on the metathorax.
The presence of a single pair of wings distinguishes true flies from other insects with "fly" in their name, such as mayflies, dragonflies, damselflies, stoneflies, whiteflies, fireflies, alderflies, dobsonflies, snakeflies, sawflies, caddisflies, butterflies or scorpionflies. Some true flies have become secondarily wingless, especially in the superfamily Hippoboscoidea, or among those that are inquilines in social insect colonies.
Diptera is a large order, containing an estimated 240,000 species of mosquitos, gnats, midges and others, although under half of these (about 120,000 species) have been described. It is one of the major insect orders both in terms of ecological and human (medical and economic) importance. The Diptera, in particular the mosquitoes (Culicidae), are of great importance as disease transmitters, acting as vectors for malaria, dengue, West Nile virus, yellow fever, encephalitis and other infectious diseases.
