Neurons, Synapses, Action Potentials, and Neurotransmission - The Mind Project Return to MODULE PAGE Neurons, Synapses, Action Potentials, and Neurotransmission Robert Stufflebeam: Author, Artist & Animator Functions of Neurons The central nervous system [CNS] is composed entirely of two kinds of specialized cells: neurons and glia. Neurons are the basic information processing structures in the CNS. While we are considering numbers, it is worth noting that there are as many as 50 times more glia than neurons in our CNS! Because our main interest lies in exploring how information processing occurs in the brain, we are going to ignore glia. Structure of neurons While there are as many as 10,000 specific types of neurons in the human brain, generally speaking, there are three kinds of neurons: motor neurons (for conveying motor information), sensory neurons (for conveying sensory information), and interneurons (which convey information between different types of neurons). A "typical" neuron has four distinct parts (or regions). Neuronal signaling Conduction

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. We humans may not occupy the dimensional extremes of elephants or honeybees, but what few people realize is that the laws of physics place tough constraints on our mental faculties as well.

List of cognitive biases Systematic patterns of deviation from norm or rationality in judgment Cognitive biases are systematic patterns of deviation from norm and/or rationality in judgment. They are often studied in psychology, sociology and behavioral economics.[1] Although the reality of most of these biases is confirmed by reproducible research,[2][3] there are often controversies about how to classify these biases or how to explain them.[4] Several theoretical causes are known for some cognitive biases, which provides a classification of biases by their common generative mechanism (such as noisy information-processing[5]). Gerd Gigerenzer has criticized the framing of cognitive biases as errors in judgment, and favors interpreting them as arising from rational deviations from logical thought.[6] Explanations include information-processing rules (i.e., mental shortcuts), called heuristics, that the brain uses to produce decisions or judgments.

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. 1. The Robbers Cave Experiment is a classic social psychology experiment conducted with two groups of 11-year old boys at a state park in Oklahoma, and demonstrates just how easily an exclusive group identity is adopted and how quickly the group can degenerate into prejudice and antagonism toward outsiders. Researcher Muzafer Sherif actually conducted a series of 3 experiments. 2. This infamous experiment to plumb the depths of evil in human hearts ended up affecting its lead researcher as much as its subjects. 3. 4.
Remote Antarctic island is 'richer in biodiversity than the Galapagos' Antarctica's remote South Georgia Island boasts 90 percent of the world's fur seals, half of the world's elephant seals, is navigated by vast populations of blue whales, sperm whales and killer whales, and has beaches that can be packed shoulder-to-shoulder with nesting penguins. In total, it contains nearly 1,500 recorded species, many of which are found nowhere else on Earth. It's difficult to believe that until recently, this biological treasure was believed to be nothing more than an "inhospitable lump of rock." In fact, researchers now believe that South Georgia Island contains more species than anywhere else in the Southern Ocean, and may be the most biologically diverse remote island in the world — even more diverse than the storied Galapagos Islands, according to the Independent. "It shows you don't have to be a tropical island or in a hot part of the world to support a lot of marine life. The types of marine life around the island vary immensely.
