Size of synapses determines the strength of information transmission


Size of synapses determines the strength of information transmission
Nerve cells communicate with one another via synapses. Neuroscientists at the University of Zurich and ETH Zurich have now found that these connections seem to be much more powerful than previously thought. The larger the synapse, the stronger the signal it transmits. These findings will enable a better understanding of how the brain functions and how neurological disorders arise.
The neocortex is the part of the brain that humans use to process sensory impressions, store memories, give instructions to the muscles, and plan for the future. These computational processes are possible because each nerve cell is a highly complex miniature computer that communicates with around 10,000 other neurons. This communication happens via special connections called synapses. ....

El Tigre Resource Estimate
After acquiring El Tigre, Silver Tiger drilled 12,500 meters to define the wide halo of near surface gold mineralization around the mined high-grade veins of the historic El Tigre Mine. This allowed Silver Tiger to deliver a maiden resource estimate for the El Tigre Property to a depth of 150 meters containing indicated resources of 661,000 gold equivalent ounces at 0.77 g/t (21 g/t silver and 0.51 g/t gold) and inferred resources of 341,000 gold equivalent ounces at 1.59 g/t (88 g/t silver and 0.5 ....

Researchers focus on specific neurons that make reaching-and-grasping tasks possible


Researchers focus on specific neurons that make reaching-and-grasping tasks possible
Research conducted at the Okinawa Institute of Science and Technology Graduate University (OIST), has looked at the importance of specific neurons for seemingly simple, day-to-day tasks that involve reaching for and grasping objects. The study was published in
Cell Reports.
We focused on the neurons located in the basal ganglia, said Professor Gordon Arbuthnott, who leads OIST s Brain Mechanisms for Behavior Unit. This part of the brain is connected to the cerebral cortex, which is involved in motor function. And neurons, or nerve cells, are specialized cells that act as the building blocks of the nervous system - they connect input from the outside world to movement in our muscles. ....

Study: Oligodendrocytes play key role in the distribution of energy-rich molecules


Study: Oligodendrocytes play key role in the distribution of energy-rich molecules
The human brain has about as many neurons as glial cells. These are divided into four major groups: the microglia, the astrocytes, the NG2 glial cells, and the oligodendrocytes. Oligodendrocytes function primarily as a type of cellular insulating tape: They form long tendrils, which consist largely of fat-like substances and do not conduct electricity. These wrap around the axons, which are the extensions through which the nerve cells send their electrical impulses. This prevents short circuits and accelerates signal forwarding.
Astrocytes, on the other hand, supply the nerve cells with energy: Through their appendages they come into contact with blood vessels and absorb glucose from these. They then transport it to the interfaces between two neurons, the synapses. Before that, they partially convert the sugar into other energy-rich molecules. ....
