Strength of synapses prove critical in the process of learning and memory Have a tough time remembering where you put your keys, learning a new language or recalling names at a cocktail party? New research from the Lisman Laboratory points to a molecule that is central to the process by which memories are stored in the brain. A paper published in the June 22 issue of the Journal of Neuroscience describes the new findings. The brain is composed of neurons that communicate with each other...

New studies illuminate brain's complex neurotransmission machinery, point to potential source of problems leading to neurodegenerative and psychiatric conditions Two studies featuring research from Weill Cornell Medical College have uncovered surprising details about the complex process that leads to the flow of neurotransmitters between brain neurons -- a dance of chemical messages so delicate that missteps often lead to neurological dysfunction. A recent Nature Neuroscience study led by Dr....

An essential component of animal nervous systems"”sodium channels"”evolved prior to the evolution of those systems, researchers from The University of Texas at Austin have discovered. "The first nervous systems appeared in jellyfish-like animals six hundred million years ago or so," says Harold Zakon, professor of neurobiology, "and it was thought that sodium channels evolved around that time. We have now discovered that sodium channels were around well before nervous systems...

Could veterans of war, rape victims and other people who have seen horrific crimes someday have the traumatic memories that haunt them weakened in their brains? In a new study, UCLA life scientists report a discovery that may make the reduction of such memories a reality. "I think we will be able to alter memories someday to reduce the trauma from our brains," said the study's senior author, David Glanzman, a UCLA professor of integrative biology and physiology and of neurobiology. The study...

(Ivanhoe Newswire) -- Scientists believe that long-term potentiation (LTP) "“ the long-lasting increase of signals across a connection between brain cells -- underlies our ability to remember over time and to learn, but how that happens is a central question in neuroscience. Researchers at Duke University Medical Center have found a cascade of signaling molecules that allows a usually very brief signal to last for tens minutes, providing the brain framework for stronger connections...

You may remember the color of your loved one's eyes for years. But how? Scientists believe that long-term potentiation (LTP) "“ the long-lasting increase of signals across a connection between brain cells -- underlies our ability to remember over time and to learn, but how that happens is a central question in neuroscience. Researchers at Duke University Medical Center have found a cascade of signaling molecules that allows a usually very brief signal to last for tens of minutes,...

Scientists at The Scripps Research Institute and University of Pennsylvania have found a way to uncover potential drug targets that have so far remained hidden from researchers' view. By applying the new method to a type of nerve cell critical to regulating body temperature, the authors found more than 400 "receptors" (structures that bind other molecules, triggering some effect on the cell) responding to neurotransmitters, hormones, and other chemical signals. This represents 20 to 30 times...

Findings challenge conventional wisdom of how neurons operate Neurons are complicated, but the basic functional concept is that synapses transmit electrical signals to the dendrites and cell body (input), and axons carry signals away (output). In one of many surprise findings, Northwestern University scientists have discovered that axons can operate in reverse: they can send signals to the cell body, too. It also turns out axons can talk to each other. Before sending signals in reverse, axons...

Scientists at Duke University Medical Center have uncovered clues to memory and learning by exploring the function of a single gene that governs how neurons form new connections. The finding may also provide insights into a form of human mental retardation. In a study published in the Journal of Neuroscience, the scientists explored the gene WRP's functions in the brain cell (neuron) and then demonstrated how acutely memory and learning are affected when WRP is missing in mice. "Human...

The research may lead to a better understanding of diseases such as autism and schizophrenia Connected highways of nerve cells carry information to and from different areas of the brain and the rest of the nervous system. Scientists are trying to draw a complete atlas of these connections"”sometimes referred to as the "connectome""”to gain a better understanding of how the brain functions in health and disease. New research conducted at The Scripps Research Institute shows that...
