Neuroscientists at MIT's Picower Institute of Learning and Memory have uncovered why relatively minor details of an episode are sometimes inexplicably linked to long-term memories. The work is slated to appear in the Jan. 13 issue of Neuron. "Our finding explains, at least partially, why seemingly irrelevant information like the color of the shirt of an important person is remembered as vividly as more significant information such as the person's impressive remark when you recall an episode...

An unexpected discovery by UCLA life scientists holds promise for the future development of treatments for post-traumatic stress disorder and other anxiety disorders, and potentially for Alzheimer's disease and other memory-impairment diseases. The researchers, led by UCLA professor of psychology Michael Fanselow, have discovered what may be a completely unexplored drug target for the treatment of anxiety disorders. The research is published Jan. 7 in the journal Science. Normally,...

(Ivanhoe Newswire) "“ By studying human brain samples, scientists have been able to isolate a set of proteins that account for over 130 different brain diseases "“ the leading causes of mental disability with an economic costs in the USA that exceeds $300 billion.  This discovery provides new insight into the evolution of behavior. The brain is a multifaceted organ in the body with millions of nerve cells connected by billions of synapses.  It's rather complex if you...

A new study is unraveling the earliest events associated with neurodegenerative diseases characterized by abnormal accumulation of tau protein. The research, published by Cell Press in the December 22 issue of the journal Neuron, reveals how tau disrupts neuronal communication at synapses and may help to guide development of therapeutic strategies that precede irreversible neuronal degeneration. Tau normally contributes to the supportive framework of proteins in the cell. It is well...

How GABA transmission regulates synaptic adhesion at developing inhibitory synapses Newly published research led by Professor Z. Josh Huang, Ph.D., of Cold Spring Harbor Laboratory (CSHL) sheds important new light on how neurons in the developing brain make connections with one another. This activity, called synapse validation, is at the heart of the process by which neural circuits self-assemble, and is directly implicated in pathology that gives rise to devastating neurodevelopmental...

A set of brain proteins is found to play a role in over 100 brain diseases and provides a new insight into evolution of behavior In research published Sunday, scientists have studied human brain samples to isolate a set of proteins that accounts for over 130 brain diseases. The paper also shows an intriguing link between diseases and the evolution of the human brain. Brain diseases are the leading cause of medical disability in the developed world according to the World Health Organization...

Yale University researchers have found that a single molecule not only connects brain cells but also changes how we learn. The findings, reported in the December 9 issue of the journal Neuron, may help researchers discover ways to improve memory and could lead to new therapies to correct neurological disorders. The junctions between brain cells over which nerve pulses pass "” called synapses "” are crucial for regulating learning and memory and how we think. Aberrations in the...

Scientists from Germany, UK and Italy identify a molecular switch that leads to a sustained increase of calcium in nerve cells and plays a crucial role in the formation of memory and addictive behaviors. Learning and memory formation are based on the creation of new connections between neurons in the brain. Also, behaviors such as nicotine addiction manifest themselves in long-term changes of neuronal connectivity and can "“ at least in this respect "“ be viewed as a form of...

Researchers at the Stanford University School of Medicine, applying a state-of-the-art imaging system to brain-tissue samples from mice, have been able to quickly and accurately locate and count the myriad connections between nerve cells in unprecedented detail, as well as to capture and catalog those connections' surprising variety. A typical healthy human brain contains about 200 billion nerve cells, or neurons, linked to one another via hundreds of trillions of tiny contacts called...

The brain, a complex network The human brain is composed of 100 billion individual nerve cells which communicate with each other via a complex network of connections. Errors in communications of these cells are often at the basis of brain and nerve diseases such as Alzheimer's and multiple sclerosis. In the search for possible solutions to these diseases, one important aspect is to understand how the connections between nerve cells develop. Drosophila as a model organism The fruit fly,...

  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
