Tech. Tech. The Human Brain - Stress. Chronic over-secretion of stress hormones adversely affects brain function, especially memory.
Too much cortisol can prevent the brain from laying down a new memory, or from accessing already existing memories. The renowned brain researcher, Robert M. Eye movements reveal unconscious memory retrieval : Neurophilosophy. THIS short film clip shows two images of the same scene.
Watch it carefully, and see if you can spot the subtle differences between them. As you watch, your eyes will dart back and forth across the images, so that you can perceive the most important features. Bodily motions influence memory and emotions : Neurophilosophy. WHEN talking about our feelings, we often use expressions that link emotions with movements or positions in space.
If, for example, one receives good news, they might say that their “spirit soared”, or that they are feeling “on top of the world”. Conversely, negative emotions are associated with downward movements and positions – somebody who is sad is often said to be “down in the dumps”, or feeling “low”. According to a new study published in this month’s issue of the journal Cognition, expressions such as these are not merely metaphorical. The research provides evidence of a causal link between motion and emotion, by showing that bodily movements influence the recollection of emotional memories, as well as the speed with which they are recalled.
For their latest study, Casasanto and Dijkstra recruited 24 undergraduates and asked them to sit at a desk in front of a laptop computer. The woman who knows no fear : Neurophilosophy. SM has been studied extensively during the past two decades.
Early investigations showed that her non-verbal visual memory was signficantly impaired but that otherwise she had an IQ in the low-average range. She also displayed inappropriate social behaviours, quickly becoming friendly with the experimenters and making sexual remarks, due to disturbed executive control. Neurostress: How Stress May Fuel Neurodegenerative Diseases. In 2007, James Watson eyed his genome for the very first time.
Through more than 50 years of scientific and technological advancement, Watson saw the chemical structure he once helped unravel now fused into a personal genetic landscape laid out before him.

Attention deficit hyperactivity disorder (ADHD) is one of the most well-recognized childhood developmental problems. This condition is characterized by inattention, hyperactivity and impulsiveness. It is now known that these symptoms continue into adulthood for about 60% of children with ADHD. Recommended Related to ADD-ADHD. Mini-strokes leave 'hidden' brain damage. Each year, approximately 150,000 Canadians have a transient ischemic attack (TIA), sometimes known as a mini-stroke.
New research published January 28 in Stroke, the journal of the American Heart Association shows these attacks may not be transient at all. They in fact create lasting damage to the brain. The stroke research team, led by Dr. Lara Boyd, physical therapist and neuroscientist with the Brain Research Centre at Vancouver Coastal Health and the University of British Columbia, studied 13 patients from the Stroke Prevention Clinic at Vancouver General Hospital and compared them against 13 healthy study participants. The TIA subjects had all experienced an acute episode affecting motor systems, but had symptoms resolved within 24 hours.
Our brains are wired so we can better hear ourselves speak, new study shows. Like the mute button on the TV remote control, our brains filter out unwanted noise so we can focus on what we’re listening to.
But when it comes to following our own speech, a new brain study from the University of California, Berkeley, shows that instead of one homogenous mute button, we have a network of volume settings that can selectively silence and amplify the sounds we make and hear. Activity in the auditory cortex when we speak and listen is amplified in some regions of the brain and muted in others. In this image, the black line represents muting activity when we speak. Cognitive Enhancement Versus Drug War. Cognitive enhancement is not about future generations playing video games via neural implants and thought interfaces.
Presently, it is about a large fraction of the worlds scientist shortening their lives (speak about lifespan enhancement) via caffeine, nicotine, and sugar intake that leads to diabetes and cardio vascular illnesses via hypertension with high blood pressure and heart troubles, teeth grinding, frequent urination, and so on. Coffee is a must at all conferences. Think Different: How Perception Reveals Brain Differences. PERCEPTUAL PSYCHOLOGY and the brain sciences emphasize the communality in the way that people experience reality.
SEX ADDS YEARS TO YOUR LIFE ... The Flashing Images above are designed to provide a "Mental Image" of what takes place when your brain's Pleasure Pathway is stimulated by activities associated with feeling good. Science now believes positive stimulation of your built in reward system can add many quality years to your life. Few activities stimulate our pleasure pathway more than Sexual Intercourse........... Brain Tour. Neural Networks Forget Information Quickly. Researchers have figured out the speed that neural networks in the cerebral cortex can delete sensory information is a bit of information per active neuron per second. The activity patterns of the neural network models are deleted nearly as soon as they are passed on from sensory neurons. The scientists used neural network models based on real neuronal properties for the first time for these calculations.
Neuronal spike properties were figured into the models which also helped show that the cerebral cortex processes were extremely chaotic. Neural networks and this type of research in general are all helping researchers better understand learning and memory processes. With better knowledge about learning and memory, researchers can work toward treatments for Alzheimer’s disease, dementia, learning disabilities, PTSD related memory loss and many other problems. Targeting nicotine receptors to treat cognitive impairments in schizophrenia. Smoking is a common problem for patients with schizophrenia. The increased tendency of patients diagnosed with this disorder is to not only smoke, but to do so more heavily than the general public. This raises the possibility that nicotine may be acting as a treatment for some symptoms of schizophrenia.
Nicotine acts through two general classes of brain receptors, those with high and low affinity for nicotine. The Dark Side of Oxytocin, the Hormone of Love - Ethnocentrism. Yes, you knew there had to be a catch. As oxytocin comes into sharper focus, its social radius of action turns out to have definite limits. The love and trust it promotes are not toward the world in general, just toward a person’s in-group.
Oxytocin turns out to be the hormone of the clan, not of universal brotherhood. Psychologists trying to specify its role have now concluded it is the agent of ethnocentrism. 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).
