What is Dizziness?
At some point, everyone experiences some type of dizziness. Whether you've had the flu, been pregnant, or just had a little too much to drink on occasion, you have probably felt the effects of dizziness, including blurred vision and the spins. Dizziness is generally described as a feeling of lightheaded or unsteadiness. In fact, dizziness is pretty much a blanket term for anything, from feeling off kilter to actually sensing that you are going to pass out. There are various causes of dizziness, ranging from illness to low blood pressure.
Brain and mind
The human brain is the center of the human nervous system. Enclosed in thecranium, it has the same general structure as the brains of othermammals, but is over three times as large as the brain of a typical mammal with an equivalent body size. Most of the expansion comes from the cerebral cortex, a convoluted layer of neural tissue that covers the surface of the forebrain. Especially expanded are the frontal lobes, which are associated with executive functions such as self-control, planning, reasoning, and abstract thought. The portion of the brain devoted to vision is also greatly enlarged in human beings.
Brain evolution, from the earliestshrewlike mammals through primates tohominids, is marked by a steady increase in encephalization, or the ratio of brain to body size. The human brain has been estimated to contain 80 or 90 billion (~85 109) non-neuronal cells (glial cells) as well as 80 or 90 billion (~86 109)neurons, of which about 10 billion (1010) are cortical pyramidal cells. These cells pass signals to each other via as many as 1000 trillion (1015, 1 quadrillion) synaptic connections. However, recent research has shown that the modern human brain has actually been shrinking over the last 28,000 years. The brain monitors and regulates the body's actions and reactions. It continuously receives sensory information, and rapidly analyzes these data and then responds, controlling bodily actions and functions. The brainstem controls breathing, heart rate, and other autonomic processes that are independent of conscious brain functions. The neocortex is the center of higher-order thinking, learning, and memory. Thecerebellum is responsible for the body's balance, posture, and the coordination of movement.
Despite being protected by the thick bones of the skull, suspended incerebrospinal fluid, and isolated from the bloodstream by the blood-brain barrier, the human brain is susceptible to many types of damage and disease. The most common forms of physical damage are closed head injuries such as a blow to the head, a stroke, or poisoning by a wide variety of chemicals that can act asneurotoxins. Infection of the brain is rare because of the barriers that protect it, but is very serious when it occurs. The human brain is also susceptible to degenerative disorders, such asParkinson's disease, multiple sclerosis, and Alzheimer's disease. A number of psychiatric conditions, such as schizophrenia and depression, are widely thought to be caused at least partially by brain dysfunctions, although the nature of such brain anomalies is not well understood.
Understanding the relationship between the brain and the mind is a challenging problem both philosophically and scientifically. The most straightforward scientific evidence that there is a strong relationship between the physical brain matter and the mind is the impact physical alterations to the brain have on the mind, such as with traumatic brain injury and psychoactive drug use.
The mind-body problem is one of the central issues in the history of philosophy, which asks us to consider if the brain and the mind are identical, partially distinct, or related in some unknown way. There are three major schools of thought concerning the answer: dualism, materialism, and idealism.
Dualism holds that the mind exists independently of the brain; materialism holds that mental phenomena are identical to neuronal phenomena; and idealism holds that only mental phenomena exist. In addition to the philosophical questions, the relationship between mind and brain involves a high number of scientific questions, including understanding the relationship between mental activity and brain activity, the exact mechanisms by which drugs influence cognition, and the neural.
