Electronic harassment. Electronic harassment is the alleged use of electromagnetic waves to harass a victim. Psychologists have identified evidence of auditory hallucinations, delusional disorders[1] or other mental illnesses in online communities supporting those who claim to be targeted.[2] Individuals suffering from auditory hallucinations, delusional disorders[1] or other mental illness have claimed that government agents make use of electric fields, microwaves (such as the microwave auditory effect) and radar to transmit sounds and thoughts into their heads, referring to technology that they say can achieve this as "voice to skull" or "V2K" after an obsolete military designation.[2] There are extensive online support networks and numerous websites maintained by people fearing mind control.

The human brain is divided into two hemispheres–left and right. Scientists continue to explore how some cognitive functions tend to be dominated by one side or the other; that is, how they are lateralized. The longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum. The hemispheres exhibit strong, but not complete, bilateral symmetry in both structure and function.
For example, structurally, the lateral sulcus generally is longer in the left hemisphere than in the right hemisphere, and functionally, Broca's area and Wernicke's area are located in the left cerebral hemisphere for about 95% of right-handers, but about 70% of left-handers.[1] Broad generalizations are often made in "pop" psychology about one side or the other having characteristic labels, such as "logical" for the left side or "creative" for the right. The extent of any modularity, or specialization of brain function by area, remains under investigation. Human Physiology/The endocrine system. Introduction To The Endocrine System[edit] The endocrine system is a control system of ductless glands that secrete hormones within specific organs.
Hormones act as "messengers," and are carried by the bloodstream to different cells in the body, which interpret these messages and act on them. It seems like a far fetched idea that a small chemical can enter the bloodstream and cause an action at a distant location in the body. Yet this occurs in our bodies everyday of our lives. The endocrine system provides an electrochemical connection from the hypothalamus of the brain to all the organs that control the body metabolism, growth and development, and reproduction. There are two types of hormones secreted in the endocrine system: Steroidal (or lipid based) and non-steroidal, (or protein based) hormones.
The endocrine system regulates its hormones through negative feedback, except in very specific cases like childbirth. Types of Glands[edit] Major endocrine glands. Hormones and Types[edit] Endocrine system. In addition to the specialised endocrine organs mentioned above, many other organs that are part of other body systems, such as bone, kidney, liver, heart and gonads, have secondary endocrine functions. For example the kidney secretes endocrine hormones such as erythropoietin and renin. A number of glands that signal each other in sequence are usually referred to as an axis, for example, the hypothalamic-pituitary-adrenal axis.
As opposed to endocrine factors that travel considerably longer distances via the circulatory system, other signaling molecules, such as paracrine factors involved in paracrine signalling diffuse over a relatively short distance. The word endocrine derives from the Greek words ἐνδο- endo- "inside, within," and κρίνειν krinein "to separate, distinguish". Endocrine organs and known secreted hormones[edit] Endocrine glands in the human head and neck and their hormones Hypothalamus[edit] Pineal body (epiphysis)[edit] Pituitary gland (hypophysis)[edit] Thyroid[edit] Skin[edit] Hypothalamus. The hypothalamus is located below the thalamus, just above the brainstem. In the terminology of neuroanatomy, it forms the ventral part of the diencephalon. All vertebrate brains contain a hypothalamus. In humans, it is roughly the size of an almond.
Structure[edit] Human hypothalamus (shown in red) The hypothalamus is a brain structure made up of distinct nuclei as well as less anatomically distinct areas. It is found in all vertebrate nervous systems. Nuclei[edit] The hypothalamic nuclei include the following:[2][3][4] See also: ventrolateral preoptic nucleus, periventricular nucleus. A cross section of the monkey hypothalamus displays 2 of the major hypothalamic nuclei on either side of the fluid-filled 3rd ventricle.Hypothalamic nuclei on one side of the hypothalamus, shown in a 3-D computer reconstruction[6] Neural connections[edit] The hypothalamus is highly interconnected with other parts of the central nervous system, in particular the brainstem and its reticular formation.
Thermoregulation. Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. This process is one aspect of homeostasis: a dynamic state of stability between an animal's internal environment and its external environment (the study of such processes in zoology has been called ecophysiology or physiological ecology).
If the body is unable to maintain a normal temperature and it increases significantly above normal, a condition known as hyperthermia occurs. For humans, this occurs when the body is exposed to constant temperatures of approximately 55 °C (131 °F), and any prolonged exposure (longer than a few hours) at this temperature and up to around 75 °C (167 °F) death is almost inevitable. Occasionally the temperature of the urine as it leaves the urethra may be of use. More often the temperature is taken in the mouth, axilla, ear or groin.
