According to the Cambridge Declaration on Consciousness, "near human-like levels of consciousness" have been observed in the grey parrot. [1] Animal consciousness, or animal awareness, is the quality or state of self-awareness within an animal, or of being aware of an external object or something within itself.
Take, for example, the mirror-mark test, which scientists sometimes use to see if an animal recognizes itself. In a series of studies, the cleaner wrasse fish seemed to pass the test .
A neuron (green and white) in an insect brain (blue) Insect cognition describes the mental capacities and study of those capacities in insects. The field developed from comparative psychology where early studies focused more on animal behavior. [1] Researchers have examined insect cognition in bees, fruit flies, and wasps. [2] [3]
For example, several studies have shown that performance is better on, for example, a color discrimination (e.g. blue vs green) after the animal has learned another color discrimination (e.g. red vs orange) than it is after training on a different dimension such as an X shape versus an O shape. The reverse effect happens after training on forms.
The most popular current model of self-organization in ants and other social insects is the response threshold model. A threshold for a particular task is the amount of stimulus, such as a pheromone or interactions with other workers, necessary to cause the worker to perform the associated task. A higher threshold requires a stronger stimulus ...
[3] Since most of the animals' neurons are in their partly-autonomous arms, "'for an octopus, its arms are partly self – they can be directed and used to manipulate things. But from the central brain's perspective they are partly non-self too, partly agents of their own.' This is as alien a mind as we could hope to encounter."
The "Spanish fly", Lytta vesicatoria, has been considered to have medicinal, aphrodisiac, and other properties. Human interactions with insects include both a wide variety of uses, whether practical such as for food, textiles, and dyestuffs, or symbolic, as in art, music, and literature, and negative interactions including damage to crops and extensive efforts to control insect pests.
It has been found that molluscs and insects have opioid binding sites or opioid general sensitivity. Certainly there are many examples of neuropeptides involved in vertebrate pain responses being found in invertebrates; for example, endorphins have been found in platyhelminthes, molluscs, annelids, crustaceans and insects.
