Adult neurogenesis. Neurogenesis is the process of birth of neurons wherein neurons are generated from neural stem cells.

Adult neurogenesis

Contrary to popular belief, neurogenesis continuously occurs in specific regions in the adult brain.[3] Developmental neurogenesis and adult neurogenesis differ markedly. This article is limited in scope to adult neurogenesis. In humans, new neurons are continually born throughout adulthood in two regions of the brain: In other species of mammals, particularly rodents, adult-born neurons also appear in the olfactory bulb.

Creutzfeldt–Jakob disease. Creutzfeldt–Jakob disease (CJD) is a universally fatal brain disorder.[2] Early symptoms include memory problems, behavioral changes, poor coordination, and visual disturbances.[2] Later dementia, involuntary movements, blindness, weakness, and coma occur.[2] About 90% of people die within a year of diagnosis.[2] CJD is believed to be caused by a protein known as a prion.[2] Infectious prions are misfolded proteins that can cause normally folded proteins to become misfolded.[2] Most cases occur spontaneously, while about 7.5% of cases are inherited from a person's parents in an autosomal dominant manner.[2] Exposure to brain or spinal tissue from an infected person may also result in spread.[2] There is no evidence that it can spread between people via normal contact or blood transfusions.[2] Diagnosis involves ruling out other potential causes.[2] An electroencephalogram, spinal tap, or magnetic resonance imaging may support the diagnosis.[2] Signs and symptoms[edit] Cause[edit]

5 Ways To Harness Neurogenesis: Boost Your Brain. Neurogenesis is the birth of new neurons from neural stem or progenitor cells in the brain.

5 Ways To Harness Neurogenesis: Boost Your Brain

It was long considered that the number of neurons was fixed and they did not replicate after maturity of the brain. It wasn’t until the 1990’s that neurogenesis was observed in the brains of humans, other primates and a number of other species that led to its widespread scientific acceptance.

Pixabay Many people think that their adult brain is not capable of generating new cells. That’s it. Done. Mental Health: Dissociative Amnesia. Dissociative amnesia is one of a group of conditions called dissociative disorders.

Mental Health: Dissociative Amnesia

Dissociative disorders are mental illnesses that involve disruptions or breakdowns of memory, consciousness, awareness, identity, and/or perception. A Randomized Double-Blind Sham-Controlled Study of Transcranial Direct Current Stimulation for Treatment-Resistant Major Depression. The promise and peril of DIY electrical brain stimulation. The last 15 years have seen a resurgence of interest among medical researchers in transcranial direct current stimulation, or tDCS.

The promise and peril of DIY electrical brain stimulation

It’s a mild form of brain stimulation that uses a direct, constant, low current delivered to the brain via electrodes—typically placed at both sides of the forehead to stimulate the prefrontal cortex. Some studies suggest this stimulation can help alleviate depression, offering a potential alternative for patients who want to avoid medication and the more severe electroconvulsive therapy.

Right now, this very morning, thousands of young adults in the United States are scrambling through the same minor hell. They’ve woken up to the very last in a series of half-futile phone alarms. Delirium tremens - Wikipedia. Delirium tremens (DTs) is a rapid onset of confusion usually caused by withdrawal from alcohol.

When it occurs, it is often three days into the withdrawal symptoms and lasts for two to three days. People may also see or hear things other people do not.[1] Physical effects may include shaking, shivering, irregular heart rate, and sweating.[2] Occasionally, a very high body temperature or seizures may result in death.[1] Alcohol is one of the most dangerous drugs to withdraw from.[3] Neurosemiotics.com - Semiotics of Thinking.

Known to history as Chicago Pile-1, it was celebrated in silence with a single bottle of Chianti, for those who were there understood exactly what it meant for humankind, without any need for words. Now, something new has occurred that, again, quietly changed the world forever. Like a whispered word in a foreign language, it was quiet in that you may have heard it, but its full meaning may not have been comprehended. Scientists have discovered how to 'delete' unwanted memories. How you spell “The Berenstain Bears” could be proof of parallel universes. IBVA BrainMachine. ‘Birdman’ Ending Explained - Page 3. Birdman Ending Explained: What Really Matters Iñárritu has been reluctant to share his interpretation of the ending and, instead, has actually championed open-ended debate over Birdman‘s finale.

Speaking to the Tampa Bay Times, the director made it clear: there is not one correct way to interpret the ending: “At the ending of the film, (it) can be interpreted as many ways as there are seats in the theater.” Music therapy. Music therapy is the use of interventions to accomplish individual goals within a therapeutic relationship by a professional who has completed an approved music therapy program.[1] Music therapy is an allied health profession and one of the expressive therapies, consisting of a process in which a music therapist uses music and all of its facets—physical, emotional, mental, social, aesthetic, and spiritual—to help clients improve their physical and mental health.

Music therapists primarily help clients improve their health in several domains, such as cognitive functioning, motor skills, emotional development, social skills, and quality of life, by using music experiences such as free improvisation, singing, and listening to, discussing, and moving to music to achieve treatment goals. Music therapists are found in nearly every area of the helping professions. Approaches[edit] Children[edit] Music therapy approaches used with children[edit] Illusion. An illusion is a distortion of the senses, revealing how the brain normally organizes and interprets sensory stimulation.

Though illusions distort reality, they are generally shared by most people.[1] Illusions may occur with any of the human senses, but visual illusions (optical illusions), are the most well-known and understood. The emphasis on visual illusions occurs because vision often dominates the other senses. Here’s Why You Should Consider Converting Your Music To A=432 Hz. Here's Why People Love Deep Bass Sounds In Music. Why do music lovers like it so much when the beat drops? Scientists may now have an answer. A new study from Canada's McMaster Institute for Music and the Mind investigated how the brain reacts to low- and high-pitched tones in order to explain how humans detect rhythm -- and it's much easier for us to follow deep bass sounds.

"There is a physiological basis for why we create music the way we do," study co-author Dr. How to Use Meditation to Help You Out of a Depressive State. By Robert L. How Stress Can Change the Size of Our Brains and What We Can Do to Lower It. Yale Researchers Succeed In Repairing Brain Damage Caused By Chronic Stress, Lead Poisoning, Potential Implications For Bipolar Disorder Medical News Today. How curiosity changes our brains. Participants in the study were asked to rate how curious they were to find out the answer to a specific trivia question, such as: “What does the term ‘dinosaur’ actually mean?” The participants were then placed in an MRI machine that measures brain activity, based on changes in blood flow when the brain is performing certain tasks. The participants saw the trivia question again followed by the image of a person’s face and were asked to make a specific decision about the person.

The High Cost of Neuromyths in Education. Valid neuroscience research is an increasingly useful resource for guiding interventions in education. Orchestrated objective reduction. New Learning. Brain networks 'hyper-connected' in young adults who had depression. Depression may be better predicted and understood now that University of Illinois at Chicago researchers have discovered that young adults who previously experienced the mental illness have hyper-connected emotional and cognitive networks in the brain.

UIC researchers used functional magnetic resonance imaging to examine the brain connectivity of young adults ages 18 to 23 while they were in a resting state. Thirty unmedicated young adults who had previously experienced depression and 23 healthy controls were used in the study, which has been published online in the journal PLOS ONE. Glossolalia.
