In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another cell (neural or otherwise).Santiago RamÃ³n y Cajal proposed that neurons are not continuous throughout the body, yet still communicate with each other, an idea known as the neuron doctrine. The word "synapse" comes from "synaptein", which Sir Charles Scott Sherrington and colleagues coined from the Greek "syn-" ("together") and "haptein" ("to clasp").
There are a number of factors that lead to obesity, the most obvious of which is of course eating too much, without burning the excess fat by exercising. Fact is, there are some people in the world who no matter how much they’d eat, they never seem to be satisfied, constantly consumed by a sense [...]
The brain learns basically by shifting between different strengths of its synapses, as a response to different stimuli – that much is clear. However, recently, a team of UCLA scientists have shattered the common belief about the mechanism of learning, showing that the brain learns rhythmically, and that there is an optimal ‘rhythm’, or frequency, [...]
The typical healthy human brain contains about 200 billion nerve cells, called neurons, all of which are connected through hundreds of trillions of small connections called synapses. One single neuron can lead to up to 10.000 synapses with other neurons, according to Stephen Smith, PhD, professor of molecular and cellular physiology. Along with a team [...]
