Neurons and Memory Whenever I read about someone diagnosed with Alzheimers who apparently goes in and out of the memory problems it makes me wonder how carefully they were diagnosed. There is a kind of simple partial seizure that mimics Alzheimers called a jamais vu. Sometimes this merely subtracts the sence of familiarity from a situation such that the person feels the people around him are imposters because they don't feel right. Sometimes it subtracts their memory of one element of a situation. One woman having this kind of seizure complained to the bank that her ATM card wasn't working.
The Limits of Intelligence Santiago Ramón y Cajal, the Spanish Nobel-winning biologist who mapped the neural anatomy of insects in the decades before World War I, likened the minute circuitry of their vision-processing neurons to an exquisite pocket watch. He likened that of mammals, by comparison, to a hollow-chested grandfather clock. Indeed, it is humbling to think that a honeybee, with its milligram-size brain, can perform tasks such as navigating mazes and landscapes on a par with mammals. A honeybee may be limited by having comparatively few neurons, but it surely seems to squeeze everything it can out of them. At the other extreme, an elephant, with its five-million-fold larger brain, suffers the inefficiencies of a sprawling Mesopotamian empire.
BrainMind.net When hallucinations follow depth electrode or cortical stimulation, much of the material experienced is very dream-like (Gloor 1990, 1992; Halgren et al., 1978; Malh et al., 1964; Penfield & Perot 1963) and consists of recent perceptions, ideas, feelings, and other emotions which are similarly illusionary and dream-like. Indeed, the right amygdala, hippocampus, and the right hemisphere in general (Broughton, 1982; Goldstein et al., 1972; Hodoba, 1986; Humphrey & Zangwill, 1961; Kerr & Foulkes, 1978; Meyer et al. 1987) also appear to be involved in the production of deam imagery as well as REM sleep (chapter 10). For example stimulation of the amygdala triggers and increases ponto-geniculo-occipital paradoxical activity during sleep (Calvo, et al. 1987), which in turn is associated with REM and dreaming. The Right Hemisphere & Dreams. Forgotten Dreams. Most individuals, however, have difficulty recalling their dreams.
Indoor Air Quality Introduction to Molds Molds produce tiny spores to reproduce. Mold spores waft through the indoor and outdoor air continually. Nuts and Bolts the neuron A single neuron may be connected to as many as 200 000 others, via junctions called synapses. They form an extensive network throughout the body, and can transmit signals at speeds of 100 metres per second. This enables animals to process and respond to events rapidly, for example by carrying sensory information from the ears to the brain, then instructions for movement from the brain to the leg muscles Within a neuron, signals are transmitted by a change of membrane voltage – a variation in the difference in electrical charge between the inside and outside of the cell. This electrical signal moves along the neuron as an electrical pulse (the ‘action potential’). The nature of the connection between neurons was hotly debated until early-20th-century experiments by Otto Loewi and Sir Henry Dale (a founding trustee and chairman of the Wellcome Trust) showed that signals are typically transmitted across synapses by chemicals called neurotransmitters.
The Ten Most Revealing Psych Experiments Psychology is the study of the human mind and mental processes in relation to human behaviors - human nature. Due to its subject matter, psychology is not considered a 'hard' science, even though psychologists do experiment and publish their findings in respected journals. Some of the experiments psychologists have conducted over the years reveal things about the way we humans think and behave that we might not want to embrace, but which can at least help keep us humble.
The Dark Side of Oxytocin, the Hormone of Love - Ethnocentrism Yes, you knew there had to be a catch. As oxytocin comes into sharper focus, its social radius of action turns out to have definite limits. The love and trust it promotes are not toward the world in general, just toward a person’s in-group. Oxytocin turns out to be the hormone of the clan, not of universal brotherhood. Features - Stop Ticks Reduce your chances of getting a tickborne disease by using repellents, checking for ticks, and showering after being outdoors. If you have a tick bite followed by a fever or rash, seek medical attention. Gardening, camping, hiking, and playing outdoors – when enjoying these activities, don't forget to take steps to prevent bites from ticks that share the outdoors. Ticks can infect humans with bacteria, viruses, and parasites that can cause serious illness. Diseases that you can get from a tick bite include (listed alphabetically): Other diseases that you can get from a tick in the United States include Colorado tick fever and Powassan encephalitis.
Human brain The human brain has the same general structure as the brains of other mammals, but has a more developed cortex than any other. Large animals such as whales and elephants have larger brains in absolute terms, but when measured using the encephalization quotient which compensates for body size, the human brain is almost twice as large as the brain of the bottlenose dolphin, and three times as large as the brain of a chimpanzee. Much of the expansion comes from the part of the brain called the cerebral cortex, especially the frontal lobes, which are associated with executive functions such as self-control, planning, reasoning, and abstract thought. The portion of the cerebral cortex devoted to vision is also greatly enlarged in humans. The human cerebral cortex is a thick layer of neural tissue that covers most of the brain. This layer is folded in a way that increases the amount of surface that can fit into the volume available.
10 Brilliant Social Psychology Studies Ten of the most influential social psychology experiments. “I have been primarily interested in how and why ordinary people do unusual things, things that seem alien to their natures.Why do good people sometimes act evil?Why do smart people sometimes do dumb or irrational things?” –Philip Zimbardo Like eminent social psychologist Professor Philip Zimbardo (author of The Lucifer Effect: Understanding How Good People Turn Evil), I’m also obsessed with why we do dumb or irrational things. The answer quite often is because of other people – something social psychologists have comprehensively shown.
Pineal Gland's Third Eye: One Of The Biggest Cover-ups in Human History The pineal gland (also called the pineal body, epiphysis cerebri, epiphysis or the “third eye”) is a small endocrine gland in the vertebrate brain. It produces the serotonin derivative melatonin, a hormone that affects the modulation of wake/sleep patterns and seasonal functions. Its shape resembles a tiny pine cone (hence its name), and it is located near the center of the brain, between the two hemispheres, tucked in a groove where the two rounded thalamic bodies join. Every human being’s Pineal Gland or the Third Eye can be activated to spiritual world frequencies and enables you to have the sense of all knowing, godlike euphoria and oneness all around you. A pineal gland once tuned into to proper frequencies with help of meditation, yoga or various esoteric, occult methods, enables a person to travel into other dimensions, popularly known as astral travel or astral projection or remote viewing.
