Free Essays on Mind Body

Descartes "substantialized" consciousness as unextended reality, something that can exist in the body but does not occupy space. Mind was real, yet entirely separate from matter and therefore from brain. Interactionism is his form of dualism. One extended and the other unextended, they nevertheless interact, and this interaction occurs at a specific site, the pineal gland. The theory cannot be disproved so long as there are mental phenomena whose neural correlates remain unknown. That there are mental phenomena cannot be doubted for reasons which are logically compulsive and were adopted (though not invented) by Descartes; they cannot be doubted because the very act of doubting them establishes their reality. The reality of conscious existence is confirmed each time it is denied (Critics of his ideas objected that if soul and body were substances of entirely different natures, interaction between them was in fact impossible. This Descartes protested against, but he never satisfied his critics. Nor did occasionalism fare any better because interaction between mind and brain was now simply reduced to miracle, and miracles are not the domain of experimental science with its prime emphasis upon repeatability and quantification. It seemed the problem was insoluble and needed a new approach) Mind-body interaction is so fundamental to human existence that it normally goes unnoticed and is taken for granted The mind is a complex creation consisting of both physical and as yet un-located parts. Emotions have been localised to specific neurotransmitters that affect certain brain areas, however, what causes the release of these chemicals is less well understood. Rather than being merely a collection of cells that adapt and react to our environment, we are capable of independent thought - of acting upon our environment and, ultimately, of stimulating our own thought processes Many of the therapists who operate in the field of comp...

Stink Bugs, Family Pentatomidae

Stink Bugs, Family Pentatomidae Whats more fun than a stink bug?! The insects of the family Pentatomidae do, indeed, stink. Spend a little time in your backyard or garden, and you are sure to encounter a stink bug sucking on your plants or sitting in wait of a caterpillar. About The name Pentatomidae, the stink bug family, comes from the Greek pente, meaning five and tomos, meaning section. Some entomologists say this refers to the 5-segmented antennae, while others believe it refers to the stink bugs body, which appears to have five sides or parts. Either way, adult stink bugs are easy to recognize, with wide bodies shaped like shields. A long, triangular scutellum characterizes an insect in the family Pentatomidae. Take a close look at a stink bug, and you will see the piercing, sucking mouthparts. Stink bug nymphs often resemble their adult counterparts but may lack the distinctive shield shape. Nymphs tend to stay close to the egg mass when they first emerge, but soon venture out in search of food. Look for masses of eggs on the undersides of leaves. Classification Kingdom - AnimaliaPhylum - ArthropodaClass - InsectaOrder - HemipteraFamily - Pentatomidae Diet To the gardener, stink bugs are a mixed blessing. As a group, stink bugs use their piercing, sucking mouthparts to feed on a variety of plants and insects. Most members of the family Pentatomidae suck sap from the fruiting parts of plants and can cause significant injury to the plants. Some damage foliage as well. However, predatory stink bugs overpower caterpillars or beetle larvae, keeping pest insects in check. A few stink bugs begin life as herbivores but become predators. Life Cycle Stink bugs, like all Hemipterans, undergo simple metamorphosis with three life stages: egg, nymph, and adult. The eggs are laid in groups, looking like neatly arranged rows of tiny barrels, on stems and the undersides of leaves. When nymphs emerge, they look similar to the adult stink bug but may appear rounder rather than shield-shaped. Nymphs go through five instars before becoming adults, usually in 4-5 weeks. The adult stink bug overwinters under boards, logs, or leaf litter. In some species, the nymphs may also overwinter. Special Adaptations and Defenses From the name stink bug, you can probably guess its most unique adaptation. Pentatomids expel a foul-smelling compound from special thoracic glands when threatened. In addition to deterring predators, this odor sends a chemical message to other stink bugs, alerting them to danger. These scent glands also play a role in attracting mates and even suppress attacks by harmful microorganisms. Range and Distribution Stink bugs live throughout the world, in fields, meadows, and yards. In North America, there are 250 species of stink bugs. Worldwide, entomologists describe over 4,700 species in nearly 900 genera.
