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’.

Digital Games for Brains By: Alvaro Fernandez The Robert Wood John­son Foun­da­tion (RWJF) just announced more than $1.85 mil­lion in grants for research teams to study how dig­i­tal games can improve play­ers’ health behav­iors and out­comes (both brain-based and behavioral). The press release: Nine Lead­ing Research Teams Selected to Study How Dig­i­tal Games Improve Play­ers’ Health “Dig­i­tal games are inter­ac­tive and expe­ri­en­tial, and so they can engage peo­ple in pow­er­ful ways to enhance learn­ing and health behav­ior change, espe­cially when they are designed on the basis of well-researched strate­gies,” said (UC Santa Barbara’s Dr.

neurotransmitters and neuromodulators The soft warm living substance of the brain and nervous system stands in stark contrast to the rigid metal and plastic hardware of a modern day computer, but at the fundamental level there are clear similarities between these two apparently disparate organizational systems and, of course, one is a product of the other. Not only are the nerve cell units (neurons) self-repairing and self-wiring under the grand design built into our genes, but they can also promote, amplify, block, inhibit, or attenuate the micro-electric signals which are passed to them, and through them. In this way they give rise to signalling patterns of myriad complexity between networks of cerebral neurons, and this provides the physical substrate of mind. These key processes of signalling by one group, or family, of neurons to another is achieved largely by the secretion of tiny quantities of potent chemical substances by neuronal fibre terminals. In this way, the nerve impulses are passed on from cell to cell. 1.

Cold Coffee Recipes for a Hot Summer Day Many coffee drinkers resort to the iced versions as summertime arrives. A variety of iced coffee recipes have been shared all over the globe, but the ones you'll find here are a bit more adventurous. There's an art to making a scrumptious cup of cold coffee, which involves some little tricks and a few special ingredients.

Neuron All neurons are electrically excitable, maintaining voltage gradients across their membranes by means of metabolically driven ion pumps, which combine with ion channels embedded in the membrane to generate intracellular-versus-extracellular concentration differences of ions such as sodium, potassium, chloride, and calcium. Changes in the cross-membrane voltage can alter the function of voltage-dependent ion channels. If the voltage changes by a large enough amount, an all-or-none electrochemical pulse called an action potential is generated, which travels rapidly along the cell's axon, and activates synaptic connections with other cells when it arrives.

List all the essential neurotransmitters Acetylcholine - synthesized from Choline, Lecithin, and panthothenic acid (B5), or Diethylaminoethanol (DMAE) - Arousal and orgasm - voluntary muscular control and proper tone - enhance energy and stamina - memory - long-term planning - mental focus Dopamine - synthesized from amino acid Levodopa Study Shows Meditation Changes Brain Structure in Just 8 Weeks - Family Health Guide Written by Suzannah Moss - FHG Senior Writer Participants in an 8 week mindfulness meditation class experienced structural brain changes including increased grey-matter density in the hippocampus, known to be important for learning and memory, and in structures associated with self-awareness, compassion and introspection. This is the first research to document meditation-produced changes in the brain. Previous research has identified differences in brain activity and structure between practised meditators and non-meditators. Researchers noted that long-term meditation alters brain-wave patterns, with greater activity in brain circuits involved in attention. They also found that brain regions associated with attention and sensory processing were thicker in meditators than in controls.

Brain Gym® Exercises By Kenneth Beare Updated December 16, 2014. Brain Gym® exercises are exercises designed to help the brain function better during the learning process. Making Sense of the World, Several Senses at a Time Our five senses–sight, hearing, touch, taste and smell–seem to operate independently, as five distinct modes of perceiving the world. In reality, however, they collaborate closely to enable the mind to better understand its surroundings. We can become aware of this collaboration under special circumstances. In some cases, a sense may covertly influence the one we think is dominant. When visual information clashes with that from sound, sensory crosstalk can cause what we see to alter what we hear. When one sense drops out, another can pick up the slack.

Try the Stroop Test - The Anatomy of Movement Susan Schwerin, PhD | March 5, 2013 Almost all of behavior involves motor function, from talking to gesturing to walking. But even a simple movement like reaching out to pick up a glass of water can be a complex motor task to study. Not only does your brain have to figure out which muscles to contract and in which order to steer your hand to the glass, it also has to estimate the force needed to pick up the glass. Other factors, like how much water is in the glass and what material the glass is made from, also influence the brains calculations.
