UCLA cellular neuroscientists are providing new insights into the mechanisms that underlie long-term memory â€” research with the potential to treat long-term memory disorders.
When the eye tracks a birdâ€™s flight across the sky, the visual experience is normally smooth, without interruption. But underlying this behavior is a complex coordination of neurons that has remained mysterious to scientists. Now, University of California, San Francisco (UCSF) researchers have broken ground in understanding how the brain generates this tracking motion, a finding that offers a window, they say, into how neurons orchestrate all of the bodyâ€™s movements.
Most people know it from experience: After so many hours of being awake, your brain feels unable to absorb any more -- and several hours of sleep will refresh it.
By Anthony J. Brown, MD NEW YORK (Reuters Health) - When someone suffers a stroke, 1.9 million nerve cells in the brain die each minute, and the oxygen-starved brain ages about 3.6 years each hour -- further emphasizing the need for rapid treatment -- researchers say.

Neurons experience large-scale changes across their dendrites during learning, say neuroscientists at The University of Texas at Austin in a new study that highlights the important role that these cell regions may play in the processes of learning and memory.
Botox, used by Hollywood stars to smooth out facial wrinkles, is playing an important role in UQ research to understand how nerve cells communicate with each other.
Inhibitory systems are essential for controlling the pattern of activity in the cortex, which has important implications for the mechanisms of cortical operation, according to a Yale School of Medicine study in Neuron.
Rutgers' Bonnie Firestein likens nerve cells to trees -- some are short and bushy with many branches while others are tall with a few branches coming out of one or two main trunks. Different branching patterns correlate with specific disorders and Firestein's quest is to discover how these dissimilar patterns come about and why.
Every neurobiology textbook invariably states that nerve cells communicate with each other through synapses, the specialized cell-cell contacts found at the end of the cells' threadlike extensions. In this week's journal Science, researchers at the Salk Institute for Biological Sciences and the University of California at San Diego report that nerve cells, or neurons, may not have to rely on traditionally defined synapses to "talk" to each other.
