Latest Chemical synapse Stories
A UCSF study has found that a specific signaling link between neurons and muscles in the fruit fly is essential for keeping the insect's nervous system stable.
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.
Nerve cells need lots of energy to work properly, and the energy needs to be delivered to the right place at the right time. By inducing a mutation in fruit flies, researchers have figured out that a particular gene governs the movement of cells' energy-producing units, called mitochondria.
Researchers have constructed a new detailed map of the three-dimensional terrain of a synapse -- the junction between neurons which are critical for communication in the brain and nervous system. The "nano-map," which shows the tiny spines and valleys resolved at nanometer scale, or one-billionth of a meter, has already proven its worth in changing scientists' views of the synaptic landscape.
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.
Nerve cells relay messages at blink-of-the-eye speeds by squirting chemicals called neurotransmitters across tiny gaps called synapses to awaiting message receptors. But lots of different receptors and neurotransmitters work simultaneously. Which goes where to send the proper message?
Scientists at New York University School of Medicine reveal the important role of early experience in shaping neuronal development and brain plasticity in a new study published in the July 14 issue of the journal Nature.
Along with its many other functions in the body, magnesium may also help maintain learning and memory in middle age and beyond, according to a study in the Dec. 2 issue of Neuron.
