Neural networks learn to link temporally dispersed stimuli Rustling leaves, a creaking branch: To a mouse, these sensory impressions may at first seem harmless — but not if a cat suddenly bursts out of the bush. If so, they were clues of impending life-threatening danger. Robert Gütig of the Max Planck Institute of Experimental Medicine in Göttingen has now found how the brain [...]
Climate change less politicized among minority groups Race and ethnicity as a function of climate-change attitudes is the subject of a recent study by Jonathon Schuldt, assistant professor of communication in the College of Agriculture and Life Sciences, and collaborator Adam Pearson, assistant professor of psychology at Pomona (Calif.) College. Their work is documented in a paper, “The role of race and [...]

Being a Contender in Psychotherapy Psychotherapy is not for the faint-of-heart. Entering therapy is a substantial risk, especially when considering there is no blue print or written guarantee that you will get better. At the same time, it is just as thrilling as it is terrifying, like a sedentary extreme … ...
Less than meets the eye: How do computers — or our brains — recognize images? We do not merely recognize objects – our brain is so good at this task that we can automatically supply the concept of a cup when shown a photo of a curved handle or identify a face from just an ear or nose. Neurobiologists, computer scientists, and robotics engineers are all interested in understanding how [...]
Wealth doesn’t protect US blacks from greater chance of incarceration The chances of incarceration in America are always higher for blacks than for whites or Hispanics, regardless of their level of wealth, according to a new study led by Khaing Zaw of Duke University in the U.S. In addition, blacks and Hispanics who had previously served jail time were significantly poorer than their white counterparts. [...]
New studies of the ‘natural history’ of schizophrenia raise hope for new treatments Emerging evidence on the development, “prodromal” characteristics, and long-term course of schizophrenia provide reasons for optimism for developing new treatments and preventive approaches for this devastating disorder, according to the special March/April issue of Harvard Review of Psychiatry. The journal is published by Wolters Kluwer. “This special issue of the Harvard Review of Psychiatry brings [...]
Serotonin deficiency implicated in rheumatoid arthritis For the first time, serotonin (5-hydroxytryptamine, 5-HT) has been directly implicated in the pathophysiology of rheumatoid arthritis (RA). Although 5-HT is predominantly known as a neurotransmitter within the central nervous system, new evidence points to additional important functions for serotonin in the periphery. A report in The American Journal of Pathology shows that experimentally-induced RA [...]
10 Ways Animals Improve Mental Health More and more, animals are becoming a part of people’s lives. According to a Harris Poll, more than 3 in 5 American households have pets. That’s 62% of families have … ...
14 Ways to Identify a Bully We all have a story about being bullied as a child. Whether we were bullied for the way we spoke, what we believed or how bad we were at sports, we’ve all experienced bullying in one way or another. It is easy to presume this sort f behaviour is only prevalent for children and adolescents, […]

Patterns of brain swelling may explain susceptibility of children to cerebral malaria Brain swelling is a strong predictor of death in children with cerebral malaria (a severe form of the disease where parasites have accumulated in brain vessels), and also in mice with experimental cerebral malaria. A high-resolution whole brain imaging analysis of swelling in ECM suggests that cerebral malaria depends on the permissive environment in a specific brain area.
Grid cells' role in human imagination revealed Evidence of grid cell activity has been seen in healthy volunteers asked to imagine moving through an environment. The study used fMRI scans to detect brain activity consistent with grid cell activity in the entorhinal cortex, an important 'hub' for navigation and memory. The entorhinal cortex is one of the first areas affected by Alzheimer's disease, so the latest research could help to explain why people with Alzheimer's can have problems imagining as well as remembering things.
Scientists watch activity of newborn brain cells in mice; reveal they are required for memory Neuroscientists have described the activity of newly generated brain cells in awake mice -- a process known as adult neurogenesis -- and revealed the critical role these cells play in forming memories. The new research also offers clues as to what happens when the memory-encoding process goes awry.
Blame your noisy brain for misses and fumbles No matter how much we practice a given movement, it will still be imperfect. The reason for this frustration, according to a new study by neuroscientists, is in how we sense the world. A given individual neuron varies in its activity even when we see exactly the same scene, producing a certain kind of brain noise that affects our responding movements.
Super-clear synapses at super resolutions Researchers have developed a way to obtain super-resolution 3-D images of delicate structures deep in the brain.The work describes a new process for making brain tissue transparent that outperforms other methods and allows extremely detailed imaging of tiny but important structures within neurons.
