Neuroplasticity
Contrary to conventional thought as expressed in this diagram, brain functions are not confined to certain fixed locations. Neuroplasticity, also known as brain plasticity, is an umbrella term that encompasses both synaptic plasticity and non-synaptic plasticity—it refers to changes in neural pathways and synapses which are due to changes in behavior, environment and neural processes, as well as changes resulting from bodily injury.[1] Neuroplasticity has replaced the formerly-held position that the brain is a physiologically static organ, and explores how - and in which ways - the brain changes throughout life.[2] Neuroplasticity occurs on a variety of levels, ranging from cellular changes due to learning, to large-scale changes involved in cortical remapping in response to injury. The role of neuroplasticity is widely recognized in healthy development, learning, memory, and recovery from brain damage.

Right Brain, Left Brain? Scientists Debunk Popular Theory
Maybe you're "right-brained": creative, artistic, an open-minded thinker who perceives things in subjective terms. Or perhaps you're more of a "left-brained" person, where you're analytical, good at tasks that require attention to detail, and more logically minded. It turns out, though, that this idea of "brained-ness" might be more of a figure of speech than anything, as researchers have found that these personality traits may not have anything to do with which side of the brain you use more. Researchers from the University of Utah found with brain imaging that people don't use the right sides of their brains any more than the left sides of their brains, or vice versa. "It's absolutely true that some brain functions occur in one or the other side of the brain. Anderson and his colleagues, who published their new study in the journal PLOS ONE, looked at brain scans from 1,011 people between ages 7 and 29.
Force of habit: Stress hormones switch off areas of the brain for goal-directed behaviour
Cognition psychologists at the Ruhr-Universität together with colleagues from the University Hospital Bergmannsheil (Prof. Dr. Martin Tegenthoff) have discovered why stressed persons are more likely to lapse back into habits than to behave goal-directed. The team of PD Dr. Two stress hormones in use In order to test the different stress hormones, the cognition psychologists used three substances – a placebo, the stress hormone hydrocortisone and yohimbine, which ensures that the stress hormone noradrenaline stays active longer. Goal-directed behaviour and habits investigated in the experiment In the experiment, all participants – both male and female – learned that they would receive cocoa or orange juice as a reward if they chose certain symbols on the computer. Combined effect of yohimbine and hydrocortisone As expected, volunteers who took yohimbine and hydrocortisone did not behave goal-directed but according to habit.
20 Amazing Facts About Your Brain
The human brain is amazing and the more I read about it the more fascinated I become with not only it’s limitations, but also it’s immense power.

Your brain just loves continuity and it loves familiarity, so even though you may consciously think your partners name had zero to do with you falling in love and it was really their perfectly formed personality, you’d be wrong. 3.

5 common beliefs about the human brain that are actually totally false
MYTH: HUMANS USE ONLY 10 PERCENT OF THEIR BRAIN FACT: The 10 percent myth (sometimes elevated to 20) is mere urban legend, one perpetrated by the plot of the 2011 movieLimitless, which pivoted around a wonder drug that endowed the protagonist with prodigious memory and analytical powers. In the classroom, teachers may entreat students to try harder, but doing so will not light up “unused” neural circuits; academic achievement does not improve by simply turning up a neural volume switch.MYTH: “LEFT BRAIN” and “RIGHT BRAIN” PEOPLE DIFFER FACT: The contention that we have a rational left brain and an intuitive, artistic right side is fable: humans use both hemispheres of the brain for all cognitive functions. The left brain/right brain notion originated from the realization that many (though not all) people process language more in the left hemisphere and spatial abilities and emotional expression more in the right.
Neurogenesis: How To Grow New Brain Cells
Adults can still grow new brain cells — neurogenesis — but what are they for? For a long time scientists believed that neurogenesis was impossible: adults had all the brain cells they were ever going to have. Now we know that’s not true. In fact, we continue to grow new brain cells into adulthood. The race is on to find out what these brain cells are for and how we can grow more of them. A new review of the scientific literature, published in the journal Trends in Cognitive Sciences, argues that the growth of new cells aids adaptation to the environment (Opendak & Gould, 2015). The authors focus on new cells growing in the hippocampus, an area of the brain linked to memory and learning. Maya Opendak, who co-authored the study, said: “New neurons may serve as a means to fine-tune the hippocampus to the predicted environment.In particular, seeking out rewarding experiences or avoiding stressful experiences may help each individual optimize his or her own brain.” Ms Opendak said:
