Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...
Plant communication encompasses communication using volatile organic compounds, electrical signaling, and common mycorrhizal networks between plants and a host of other organisms such as soil microbes, [2] other plants [3] (of the same or other species), animals, [4] insects, [5] and fungi. [6]
Animals produce signals to attract the attention of a possible mate or to solidify pair bonds. These signals frequently involve the display of body parts or postures. For example, a gazelle will assume characteristic poses to initiate mating. Mating signals can also include the use of olfactory signals or mating calls unique to a species.
Animals detect touch by the somatosensory system which responses to changes at the surface or inside the body. The mechanoreceptors in the somatosensory system can be found the skin surface of most aquatic animals, as well as on the vibrissae of pinnipeds or on the hair of whales. Tactile signals are used for:
Multimodal perception is how animals form coherent, valid, and robust perception by processing sensory stimuli from various modalities. Surrounded by multiple objects and receiving multiple sensory stimulations, the brain is faced with the decision of how to categorize the stimuli resulting from different objects or events in the physical world.
The somatosensory system assimilates many kinds of information from the environment: temperature, texture, pressure, proprioception, and pain. The signals vary for each of these perceptions, and the receptor systems reflect this: thermoreceptors, mechanoreceptors, nociceptors, and chemoreceptors.
Overall, they found touch can benefit human physical and mental health no matter one's age or current state of wellness, though some specifications can provide higher benefits than others.
Hormonal sentience, first described by Robert A. Freitas Jr., describes the information processing rate in plants, which are mostly based on hormones instead of neurons like in all major animals (except sponges). Plants can to some degree communicate with each other and there are even examples of one-way-communication with animals.
