Synaptic connections are made and broken in an activity-dependent manner in diverse regions of the nervous system. However, whether activity is strictly necessary for synapse elimination has not been ...

A synthetic optoelectronic synapse between an artificial neuron and muscle. (Courtesy: Yeongjun Lee) Researchers in Korea and the US have engineered a light-activated synthetic synapse that enables an ...

Nematode movement involves coordinated muscle contractions that are regulated by complex interactions between motor neurons on the worm's dorsal (upper) and ventral (lower) sides. Two classes of ...

Muscle contraction is the tightening, shortening, or lengthening of muscles when you do some activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.

Your skeletal muscles are made up of bunches of elongated, rod-shaped cells called muscle fibres. Each of your muscle cells is packed full of thinner fibres called myofibrils. These fibres contain ...

Red wine, and metformin, a drug often prescribed to fight type 2 diabetes, have many of the neuroprotective benefits of a low-calorie diet and exercise, say researchers. Scientists have discovered ...

The origin is the end of a muscle which is attached to a fixed bone. The insertion is the other end of the muscle that is attached to the bone which moves. Muscular contractions are defined as the ...

A concentric contraction is a type of muscle activation that causes tension on your muscle as it shortens. As your muscle shortens, it generates enough force to move an object. This is the most ...

When you run, walk, lift weights, do Pilates, or engage in any sort of exercise, your muscles contract. The action of contraction prompts your muscles to release myokines. Those molecules then go all ...
