Brain Structures and Their Functions The nervous system is your body's decision and communication center. The central nervous system (CNS) is made of the brain and the spinal cord and the peripheral nervous system (PNS) is made of nerves. Together they control every part of your daily life, from breathing and blinking to helping you memorize facts for a test. Nerves reach from your brain to your face, ears, eyes, nose, and spinal cord... and from the spinal cord to the rest of your body.
When Complex Trauma Is Misdiagnosed as Anxiety 3K+Save I’ve been living with the effects of complex trauma for a long time, but for many years, I didn’t know what it was. Off and on throughout my life, I’ve struggled with what I thought was anxiety and depression. Or rather, In addition to being traumatized, I was anxious and depressed. Regardless of the difference, no condition should ever be minimized. If you are feeling anxious or depressed, it’s important and urgent to find the right support for you.
Complex (psychology) For alternate usage, see complexity. A complex is a core pattern of emotions, memories, perceptions, and wishes in the personal unconscious organized around a common theme, such as power or status (Schultz, D. & Schultz, S., 2009). Primarily a psychoanalytic term, it is found extensively in the works of Carl Jung and Sigmund Freud. Mindfulness meditation training changes brain structure in eight weeks Participating in an 8-week mindfulness meditation program appears to make measurable changes in brain regions associated with memory, sense of self, empathy and stress. In a study that will appear in the January 30 issue of Psychiatry Research: Neuroimaging, a team led by Massachusetts General Hospital (MGH) researchers report the results of their study, the first to document meditation-produced changes over time in the brain's grey matter. "Although the practice of meditation is associated with a sense of peacefulness and physical relaxation, practitioners have long claimed that meditation also provides cognitive and psychological benefits that persist throughout the day," says Sara Lazar, PhD, of the MGH Psychiatric Neuroimaging Research Program, the study's senior author.
Science: A New Map of the Human Brain Who hasn't heard that people are either left-brained or right-brained—either analytical and logical or artistic and intuitive, based on the relative "strengths" of the brain's two hemispheres? How often do we hear someone remark about thinking with one side or the other? A flourishing industry of books, videos and self-help programs has been built on this dichotomy. You can purportedly "diagnose" your brain, "motivate" one or both sides, indulge in "essence therapy" to "restore balance" and much more. Brain Waves The human brain is more complex than your scientists suspect. They are busily mapping where certain functions occur, and how parts of the brain activate in syncronicity. They know that parts of the brain, near the stem, are older than, for instance, the forebrain, and that a human can survive remarkably well with only half a brain, as long as that half is either the right or left, intact. But what your scientists do not know is that beyond the old brain and the new, the subconscious and the conscious, the right and the left halves - there are yet more subdivisions of the human brain. Where it is known that the brain seems to specialize in activity that requires Beta frequency brain waves during wakefulness, and Alpha frequency waves during sleep or meditation, and Theta waves during rage, and Delta waves in coma - no one is quite sure why. We will tell you.
Psst! The Human Brain Is Wired For Gossip hide captionLearning juicy details about someone can change the way you see them — literally, according to a new study. August Darwell/Getty Images Hearing gossip about people can change the way you see them — literally. Negative gossip actually alters the way our visual system responds to a particular face, according to a study published online by the journal Science. The findings suggest that the human brain is wired to respond to gossip, researchers say. And it adds to the evidence that gossip helped early humans get ahead. Women's exercise linked to lower cognitive skill - health - 07 January 2011 WOMEN who habitually take strenuous exercise might be at risk of damaging their cognitive function later in life. Strenuous exercise is known to reduce oestrogen levels in women and girls. This can delay the start of menstruation, and can lead to irregular periods in adult women. Low levels of oestrogen in premenopausal women have been linked to impaired mental function in later life. Mary Tierney at the University of Toronto, Canada, reasoned that strenuous exercise might therefore lead to impaired cognition in later life. She asked 90 healthy post-menopausal women to report their life-long exercise habits, and then tested their cognitive ability.
BrainMind.net When hallucinations follow depth electrode or cortical stimulation, much of the material experienced is very dream-like (Gloor 1990, 1992; Halgren et al., 1978; Malh et al., 1964; Penfield & Perot 1963) and consists of recent perceptions, ideas, feelings, and other emotions which are similarly illusionary and dream-like. Indeed, the right amygdala, hippocampus, and the right hemisphere in general (Broughton, 1982; Goldstein et al., 1972; Hodoba, 1986; Humphrey & Zangwill, 1961; Kerr & Foulkes, 1978; Meyer et al. 1987) also appear to be involved in the production of deam imagery as well as REM sleep (chapter 10). For example stimulation of the amygdala triggers and increases ponto-geniculo-occipital paradoxical activity during sleep (Calvo, et al. 1987), which in turn is associated with REM and dreaming. The Right Hemisphere & Dreams.
Know Your Neurons: How to Classify Different Types of Neurons in the Brain’s Forest Previously, on Know Your Neurons:Chapter 1: The Discovery and Naming of the Neuron Chapter 2: How to Classify Different Types of Neurons, or The Dendrology of the Neuron Forest Scientists have organized the cells that make up the nervous system into two broad groups: neurons, which are the primary signaling cells, and glia, which support neurons in various ways. Halo Effect The idea that global evaluations about a person bleed over into judgements about their specific traits. The ‘halo effect’ is a classic finding in social psychology. It is the idea that global evaluations about a person (e.g. she is likeable) bleed over into judgements about their specific traits (e.g. she is intelligent).
Myers-Briggs Type Indicator Model of personality types A chart with descriptions of each Myers–Briggs personality type and the four dichotomies central to the theory The Myers–Briggs Type Indicator (MBTI) is an introspective self-report questionnaire indicating differing psychological preferences in how people perceive the world and make decisions. The original versions of the MBTI were constructed by two Americans, Katharine Cook Briggs and her daughter Isabel Briggs Myers. The MBTI is based on the conceptual theory proposed by Swiss psychiatrist Carl Jung, who had speculated that people experience the world using four principal psychological functions – sensation, intuition, feeling, and thinking – and that one of these four functions is dominant for a person most of the time. The four categories are Introversion/Extraversion, Sensing/Intuition, Thinking/Feeling, Judging/Perception. Each person is said to have one preferred quality from each category, producing 16 unique types.
Where is The Mind?: Science gets puzzled and almost admits a non-local mentalscape. This will be the last "home-produced" blog entry for a while [save the short "Everyday Spirituality" which will follow it as a sign-off] . West Virginia beckons tomorrow morning and off I will go to whatever that entails. As I said in one of the commentary responses the other day, I hope that reading two journal runs "cover-to-cover" will bring up a few thoughts worth sharing. The Split Brain Experiments Lists of Nobel Prizes and Laureates The Split Brain Experiments Play the Split Brain Experiments About the game The split brain experiments revealed that the right and left hemisphere in the brain are good at different things. For instance, the right hemisphere is good at space perception tasks and music while the left is good at verbal and analytic tasks.
