Image of the Week: Critical Communication for Movement

Motor neurons are crucial for movement, from the simplest step to the most complex dance.

Every movement we make — from walking and writing to blinking and talking — requires intricate communication between the brain and our muscles. Our sensory systems guide this communication by providing information about the external environment and then work with the motor system to plan movements and to control the actions that muscles make. Scientists are using new imaging, molecular, and cellular tools to explore the complex interactions between brain regions and systems every time a movement is planned. Ongoing studies are helping researchers map how brain regions work together to control movement and how dysfunction in these regions contributes to movement disorders, including amyotrophic lateral sclerosis (ALS). Researchers continue to study why the nerve cells that control planned movements begin to break down in people with ALS. These studies could one day lead to new treatments and physical therapy options for people with movement disorders, or those whose movement has been compromised by stroke or injury.

The basic function of the brain is to produce behaviors, which are, first and foremost, movements. Several different regions of the cerebral cortex are involved in controlling the body's movements.

More Complex Movements

Networks of spinal neurons also participate in controlling the alternating action of the legs during normal walking, maintaining posture, and, to a large degree, in all movements.

Involuntary Movements

Perhaps the simplest and most fundamental movements are reflexes. These are relatively fixed, automatic muscle responses to particular stimuli, such as the slight extension of the leg when a physician taps the knee with a small rubber hammer.
