Latest Chemical synapse Stories
Brain cells, or neurons, transmit electrical signals efficiently only when they recycle tiny cellular sacs that store signaling chemicals called neurotransmitters.
A team of neuroscientists at Cold Spring Harbor Laboratory (CSHL) has demonstrated the mechanism by which a signaling protein found throughout the brain controls the maturation and strength of excitatory synapses, the tiny gaps across which the majority of neurons communicate.
University of Oregon-University of California, Davis, collaboration finds mechanism locking two neurons.
The instruction manual for maintaining an efficient brain may soon include a section on synaptotagmin-IV (Syt-IV), a protein known to influence learning and memory, thanks to a study by University of Wisconsin-Madison researchers.
The enchantingly colored seashells that lend beaches their charm could also provide information about how the brain converts memories and sensory information into action, according to research from the University of California at Berkeley and the University of Pittsburgh published online April 7 in the â€œProceedings of the National Academy of Sciencesâ€ (â€œPNASâ€).
Ask a simple question, get a simple answer: When Abraham Lincoln was asked how long a manâ€™s legs should be, he absurdly replied, â€œLong enough to reach the ground.â€
Sleep, already recognized as a promoter of long-term memories, also helps clear room in the brain for new learning, U.S. researchers said. Researchers at Washington University School of Medicine in St.
If you've ever been sleep-deprived, you know the feeling that your brain is full of wool.
To a growing axon, the protein RGMa is a "Wrong Way" sign, alerting it to head in another direction. As Hata et al. demonstrate in the March 9, 2009 issue of the Journal of Cell Biology, translating that signal into cellular action requires teamwork from two receptors.
