Female Orgasm Captured In Brain Scan Animation Scientists have created the world's first video animation of the female orgasm, using a series of brain scan images. To capture the brain activity, researchers monitored a woman's brain as she lay in a functional magnetic resonance imaging (fMRI) scanner and stimulated herself. Psychologists at Rutgers University in New Jersey, where the study was conducted, hope the research will help them to understand the reasons why some men and women cannot reach sexual climax. Researcher, Professor Barry Komisaruk, who presented the findings at the Society for Neuroscience annual meeting in Washington DC on Monday, told the Guardian: "The general aim of this research is to understand how the orgasm builds up from genital stimulation and what parts of the brain become recruited and finally build up into an orgasm." The animation is made up of a sequence of brain scans of Nan Wise, a 54-year-old PhD student and sex therapist in Komisaruk's lab. "We're using orgasm as a way of producing pleasure.
Eskeletons How the kidney works Each kidney contains about a million tiny structures called nephrons. A nephron has a cup-shaped Bowman's capsule leading into the renal tubule. The two sections of each nephron extend across the two different regions of the kidney: the Bowman's capsules are found within the outer cortex regionthe renal tubules run from the cortex into the darker medulla How does the kidney balance the blood? Placed end to end, the nephrons of one kidney would stretch about 8 km. A branch of the renal artery supplies the nephrons with blood.
Cartographies des connaissances scientifiques Comment cartographier les sciences? De la "Métaphysique" d'Aristote à la classification de Dewey, le classement des savoirs est un enjeu philosophique majeur. Raphaël Velt retrace les cartes historiques et s'intéresse à leurs utilisations. Article publié sur OWNISciences sous le titre, Les connaissances scientifiques à la carte Les techniques cartographiques peuvent s’appliquer à toutes les disciplines scientifiques, notamment en biologie où elles servent entre autres à décrire les réseaux trophiques (plus connus sous le nom réducteur de « chaînes alimentaires ») ainsi que les réseaux complexes d’interactions entre molécules. Les techniques cartographiques peuvent en effet décrire l’état des connaissances scientifiques ainsi que la dynamique de la recherche. Une brève histoire de l’organisation des connaissances Système figuré des connoissances humaines Cette classification vieille de deux siècles et demi semble aujourd’hui quelque peu désuète.

Master Muscle List Home Page Cell Membrane Structure and Function The Plasma Membrane fluid mosaic model, semi-permeable (selectively permeable), double layer of phospholipids with embedded proteins Jobs of the cell membrane Isolate the cytoplasm from the external environment Regulate the exchange of substances Communicate with other cells Identification Phospholipids (fats) contain a hydrophilic head and a nonpolar hydrophobic tail, which creates a barrier. Cholesterol - stiffens the membrane by connecting phospholipids Glycolipids - signal molecules Glycoproteins - have an attached chain of sugar (antibodies) Proteins embedded in membrane serve different functions 1. Transport Across Membrane -The membrane is selectively permeable (also called semipermeable ) - Small particles, or particles with no charge can pass through the bilayer (carbon dioxide and oxygen) - Water has a charge, does not easily cross the membrane - a channel protein, Aquaporin helps water across Passive Transport Osmosis - diffusion of water Solutions: Hypertonic | Isotonic | Hypotonic
Étienne-Jules Marey Un article de Wikipédia, l'encyclopédie libre. Étienne-Jules Marey Portrait de Marey par Nadar, vers 1880. Étienne-Jules Marey, né à Beaune le 5 mars 1830 et mort à Paris le 15 mai 1904, est un médecin et physiologiste français. Considéré à son époque comme un touche-à-tout atypique, il est un pionnier de la photographie et un précurseur du cinéma.

Brain Atlas - Introduction The central nervous system (CNS) consists of the brain and the spinal cord, immersed in the cerebrospinal fluid (CSF). Weighing about 3 pounds (1.4 kilograms), the brain consists of three main structures: the cerebrum, the cerebellum and the brainstem. Cerebrum - divided into two hemispheres (left and right), each consists of four lobes (frontal, parietal, occipital and temporal). The outer layer of the brain is known as the cerebral cortex or the ‘grey matter’. It covers the nuclei deep within the cerebral hemisphere e.g. the basal ganglia; the structure called the thalamus, and the ‘white matter’, which consists mostly of myelinated axons. – closely packed neuron cell bodies form the grey matter of the brain. Cerebellum – responsible for psychomotor function, the cerebellum co-ordinates sensory input from the inner ear and the muscles to provide accurate control of position and movement.

Anatomy and Physiology BIOL132 and BIOL232: Anatomy and Physiology I & IISpringfield Technical Community CollegeSpringfield, Massachusetts Welcome to Anatomy and Physiology on the internet! The pages here are meant to be used as a lecture supplement for anatomy and physiology students. Many students have told me that these pages have been helpful to them, so I encourage you to go through them and learn from them as well. These web pages were originally written for a partial-distance education course, but that is no longer offered. From this home page, you can link to any topic, listed as a Unit page. Please note: I have written these pages as an academic scientist.
What topics science lovers link to the most Hilary Mason, chief scientist at bitly, examined links to 600 science pages and the pages that those people visited next: The results revealed which subjects were strongly and weakly associated. Chemistry was linked to almost no other science. Biology was linked to almost all of them. Health was tied more to business than to food. The interactive lets you poke around the data, looking at connections sorted from weakest (fewer links) to strongest (more links), and nodes are organized such that topics with more links between each other are closer together. Natural next step: let me click on the nodes. [Scientific American via @hmason]
bodies-in-motion - scott-eaton.com 30 second sequences from BiM Not long ago, I had twelve artists from Natural Motion (of Morpheme and Clumsy Ninja fame) into Somerset House, my home away from home, for a four day anatomy workshop. At the end of each day we would take about 20 minutes to draw from the Bodies in Motion library. sketching from BiM We made extensive use of the timer for gesture drawing. timelapse of a sequence of 30 second poses Writing in Psychology: Experimental Report Writing Summary: Written for undergraduate students and new graduate students in psychology (experimental), this handout provides information on writing in psychology and on experimental report and experimental article writing. Contributors:Dana Lynn Driscoll, Aleksandra KasztalskaLast Edited: 2013-03-11 09:54:55 Experimental reports (also known as "lab reports") are reports of empirical research conducted by their authors. You should think of an experimental report as a "story" of your research in which you lead your readers through your experiment. As you are telling this story, you are crafting an argument about both the validity and reliability of your research, what your results mean, and how they fit into other previous work. These next two sections provide an overview of the experimental report in APA format. General-specific-general format Experimental reports follow a general to specific to general pattern. Title page Experimental reports in APA format have a title page. Crafting your story
Canvi & Temps: An Exploration of Science Over Time Bestiario, the group behind 6pli and a number of other network projects, released their most recent project - Canvi & Temps - that explores the complexity of science since the early 1920s. The first part, Temps, is two linked charts stacked on top of each other. On top are individual articles and on bottom are tags that provide context to those articles. You'll probably be tempted to read the visualization as a stacked area chart, but that wouldn't quite work. Bar height doesn't really mean anything other than there were more articles or tags in a year when the bars are small. It reminds me a lot of Bestiario's earlier Atlas of Electromagnetic Space. Then there's Canvi, which is a network view of tags and links: I'm not completely sure what I'm looking at with Canvi. The uniqueness of Canvi lays in the fact that it explores new node positioning techniques as well as their spatial relations. Yeah, I'm still not sure, but it's nice to look at. [Thanks, Jose]
