With recombi- nant tissue plasminogen activator as the only available treatment for ischemic stroke, the need to develop new stroke therapies is imperative. Neuroprotection is an experimental approach aimed at developing therapies that counteract the molecular mechanisms of stroke, which include excitotoxicity, oxidative and nitrosative stress, cortical spreading depolarizations, inflammation, necrosis and apoptosis (for review see Moskowitz et al , 2010; Furlan et al , 2003). Brain Visual Pathways - Visual Cortex. Intro | Optic Chiasm | Superior Colliculus | Visual Cortex | Lateral Geniculate Nucleus | Optic Nerve | Pulvinar Nucleus | Retina Part 1: Image-Mapped Tutorial Part 2: Matching Self-TestPart 3: Multiple-Choice Self-Test Return to main tutorial page The complexities of Visual Cortex are simplified by understanding that the neurons of this region are distinguished by the stimulus features that each detects.
The three major groups of so-called feature detectors in visual cortex include simple cells, complex cells, and hypercomplex cells. The Science of Scientific Writing. This article was originally published in the November-December 1990 issue of American Scientist.
Science is often hard to read. Most people assume that its difficulties are born out of necessity, out of the extreme complexity of scientific concepts, data and analysis. We argue here that complexity of thought need not lead to impenetrability of expression; we demonstrate a number of rhetorical principles that can produce clarity in communication without oversimplifying scientific issues. The results are substantive, not merely cosmetic: Improving the quality of writing actually improves the quality of thought.

A well-known hangover drug not only helps soothe pounding headaches but also triggers profound changes that protect the liver, USC scientists report in new findings that could help prevent alcohol-related harm.
The study focuses on dihydromyricetin (DHM), also known as ampelopsin, an over-the-counter herbal remedy. When researchers at the USC School of Pharmacy sought to understand how it works, their investigation revealed a sequence of metabolic changes responsible not only for easing headaches but also benefitting the liver. "We know DHM helps the body to metabolize alcohol faster, but how does it work? We found it activates a cascade of mechanisms that erase alcohol from the body very quickly," said Jing Liang, a research professor of clinical pharmacy and the corresponding author of the study. The study appears today in Alcoholism: Clinical and Experimental Research. Alcohol use disorders constitute the most common form of substance abuse. What is an individual? Information Theory may provide the answer. It's almost impossible to imagine biology without individuals -- individual organisms, individual cells, and individual genes, for example.
But what about a worker ant that never reproduces, and could never survive apart from the colony? Are the trillions of microorganisms in our microbiomes, which vastly outnumber our human cells, part of our individuality? "Despite the near-universal assumption of individuality in biology, there is little agreement about what individuals are and few rigorous quantitative methods for their identification," write the authors of new work published in the journal Theory in Biosciences.
The problem, they note in the paper, is analogous to identifying a figure from its background in a Gestalt psychology drawing. We Tested Europe’s New Digital Lie Detector. It Failed. They call it the Silent Talker.

Computational. Writing Quality. Blindness & Brain. Italian family's inability to feel pain spurs research on relief for chronic sufferers. Chronic pain affects millions of people, who not only suffer but also risk becoming addicted to the opioid drugs used to treat it.
A new report on six members of a three-generation Italian family who barely notice burns, bone breaks, and even red hot chili pepper extract rubbed into pricked skin, may pave the way to new painkillers — following clues from a single mutant gene. The new report, published in the journal Brain, is from James Cox, PhD, senior lecturer in the Molecular Nociception Group at University College London (UCL) and colleagues. The featured family experiences very limited pain, unlike the famous case of a 10-year-old boy from Pakistan that I’ve included in every textbook edition I’ve written. Cox and co-workers introduced the boy in a 2006 paper in Nature, “... a ten-year-old child, well known to the medical service after regularly performing 'street theatre.’
He placed knives through his arms and walked on burning coals, but experienced no pain. SchembriMirolliBaldassarre2007. The gradient of the reinforcement landscape influences sensorimotor learning.

Cookies are Not Accepted - New York Times. “They Basically Reset My Brain” MIT challenges New York Times over book on famous brain patient. He Massachusetts Institute of Technology brain sciences department and, separately, a group of some 200 neuroscientists from around the world have written letters to The New York Times claiming that a book excerpt in the newspaper’s Sunday magazine this week contains important errors, misinterpretations of scientific disputes, and unfair characterizations of an MIT neuroscientist who did groundbreaking research on human memory.
In particular, the excerpt contains a 36-volley verbatim exchange between author Luke Dittrich and MIT’s Suzanne Corkin in which she says that key documents from historic experiments were “shredded.” “Most of it has gone, is in the trash, was shredded,” Corkin is quoted as telling Dittrich before she died in May, explaining, “there’s no place to preserve it.” Destroying files related to historic scientific research would raise eyebrows, but Corkin’s colleagues say it never happened.

Shunning the habit of our times to regard these as questions for evolutionary genetics, Lane insists that our fundamental biochemical mechanisms—particularly those through which living cells generate energy—may determine or limit these facts of life. Lane has been steadily constructing an alternative, complementary view of evolution to the one in which genes compete for reproductive success and survival. He has argued that some of the big shifts during evolutionary history, such as the appearance of complex cells called eukaryotes (like our own) and the emergence of multicellular life forms, are best understood by considering the energetic constraints.
Nautilus caught up with Lane in his laboratory in London and asked him about his ideas on aging, sex, and death.
Scratching is catching in mice. Catch sight of someone scratching and out of nowhere comes an itch, too. Now, it turns out mice suffer the same strange phenomenon. Tests with mice that watched itchy neighbors, or even just videos of scratching mice, provide the first clear evidence of contagious scratching spreading mouse-to-mouse, says neuroscientist Zhou-Feng Chen of Washington University School of Medicine in St. Louis. The quirk opens new possibilities for exploring the neuroscience behind the spread of contagious behaviors. For the ghostly itch, experiments trace scratching to a peptide nicknamed GRP and areas of the mouse brain better known for keeping the beat of circadian rhythms, Chen and colleagues found.
In discovering this, “there were lots of surprises,” Chen says. Researchers housed mice that didn’t scratch any more than normal within sight of mice that flicked and thumped their paws frequently at itchy skin. Story continues below image. How Brain Scientists Forgot That Brains Have Owners - The Atlantic. It’s a good time to be interested in the brain. Neuroscientists can now turn neurons on or off with just a flash of light, allowing them to manipulate the behavior of animals with exceptional precision. They can turn brains transparent and seed them with glowing molecules to divine their structure. They can record the activity of huge numbers of neurons at once. And those are just the tools that currently exist. In 2013, Barack Obama launched the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative—a $115 million plan to develop even better technologies for understanding the enigmatic gray blobs that sit inside our skulls.
John Krakaeur, a neuroscientist at Johns Hopkins Hospital, has been asked to BRAIN Initiative meetings before, and describes it like “Maleficent being invited to Sleeping Beauty’s birthday.” A giant neuron found wrapped around entire mouse brain. Allen Institute for Brain Science A digital reconstruction of a neuron that encircles the mouse brain. Like ivy plants that send runners out searching for something to cling to, the brain’s neurons send out shoots that connect with other neurons throughout the organ. A new digital reconstruction method shows three neurons that branch extensively throughout the brain, including one that wraps around its entire outer layer. Split brain does not lead to split consciousness.

Brain’s connections which keep related memories distinct from each other, identified in new study. Credit: University of Bristol Neuroscientists at the University of Bristol are a step closer to understanding how the connections in our brain which control our episodic memory work in sync to make some memories stronger than others. The findings, published in Nature Neuroscience, reveal a previously unsuspected division of memory function in the pathways between two areas of the brain, and suggest that certain subnetworks within the brain work separately, to enhance the distinctiveness of memories. The team studied the hippocampus and prefrontal cortex—two regions of the brain critical to memory function—as damage in these areas can induce severe memory loss.

It’s always been a bit of a mystery why LSD is such a potent hallucinogen. Unlike most similar drugs, it takes only a very small dose—say around 100 micrograms—to have strong effects that last 12 hours or longer. Now, for the first time, researchers have caught LSD (or lysergic acid diethylamide) in the act of binding to a receptor in the brain, something various researchers have attempted since the drug began to be studied in the 1950s.
