Findings Friday: Using your brain to become Arnold Schwarzenegger

Ok, so maybe you won't necessarily become a professional bodybuilder just by using your thoughts, but new research suggests that regular mental imagery can help muscles sustain strength when immobilized for several weeks. The article, entitled The power of the mind: the cortex as a critical determinant of muscle strength/weakness, was published in the Journal … Continue reading Findings Friday: Using your brain to become Arnold Schwarzenegger

A neuron can be represented as an electrical equivalent circuit

A neuron can be represented as an electrical equivalent circuit, which is a mathematical model that represents all of the major electrical properties of a given neuron. An equivalent circuit is made up of batteries, capacitors and resistors.Basically, the model gives us a relatively intuitive idea of how currents are caused by ionic movement and … Continue reading A neuron can be represented as an electrical equivalent circuit

Clathrin Coats and Endocytosis

So we all know that organelles and cellular materials move about. One way that endocytic traffic occurs is via clathrin-coated vesicles. The clathrin coat, which is made of proteins, interacts through receptors with extracellular molecules that are going to be taken up into the cell. In other words, the clathrin-coats help facilitate endocytosis. Clathrin-mediated uptake … Continue reading Clathrin Coats and Endocytosis
