The mechanism which adjusts how to receive a signal in coordination with dendritic morphology has been revealed Neurons in the brain play a role as an electric wire conveying an electrical signal. Because this electric wire is connected with various joints (synapse), various brain functions can occur. A neuron which has dendritic trees on it, receives the signals with many synapses located on those dendritic trees, and carries out functions by combining the received signals. The research...

Excitation and inhibition remain balanced, even when the brain undergoes reorganization Every second, the brain's nerve cells exchange many billions of synaptic impulses. Two kinds of synapses ensure that this flow of data is regulated: Excitatory synapses relay information from one cell to the next, while inhibitory synapses restrict the flow of information. Scientists at the Max Planck Institute of Neurobiology in Martinsried could now show, in cooperation with colleagues from the Ruhr...

A fundamental new discovery about how nerve cells in the brain store and release tiny sacs filled with chemicals may radically alter the way scientists think about neurotransmission — the electrical signaling in the brain that enables everything from the way we move, to how we remember and sense the world. According to the scientists at the University of California, San Francisco (UCSF) who conducted the research, the discovery doesn´t change the players involved so much as it...

New findings explain rapid signal transmission in eye's initial response to light A scientist from the Florida campus of The Scripps Research Institute has determined how a particular gene makes night vision possible. The study, which was published in the August 10, 2011 edition of The Journal of Neuroscience, focuses on a gene called nyctalopin. Mutations in the gene result in inherited "night blindness," a loss of vision in low-light environments. "Until now, our understanding of the role...

A person who drinks too much alcohol may be able to perform complicated tasks, such as dancing, carrying on a conversation or even driving a car, but later have no memory of those escapades. These periods of amnesia, commonly known as "blackouts," can last from a few minutes to several hours. Now, at Washington University School of Medicine in St. Louis, neuroscientists have identified the brain cells involved in blackouts and the molecular mechanism that appears to underlie them. They report...

Just like human teenagers, fruit flies that spend a day buzzing around the "fly mall" with their companions need more sleep. That's because the environment makes their brain circuits grow dense new synapses and they need sleep to dial back the energy needs of their stimulated brains, according to a new study by UW- Madison sleep researchers. Researchers saw this increase in the number of synapses -- the junctions between nerve cells where electrical or chemical signals pass to the next cell...

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....

With every bodily movement"”from the blink of an eye to running a marathon"”nerve cells transmit signals to muscle cells. To do that, nerve cells rely on tiny molecular motors to transport chemical messengers (neurotransmitters) that excite muscles cells into action. It's a complex process, which scientists are still trying to understand. A new study by Syracuse University researchers has uncovered an important piece of the puzzle. The study, published in the April 22 issue of...
