Q:

What does the basal ganglia do?

A:

Quick Answer

The basal ganglia plays a role in a number of functions in the brain, including involuntary motor control and some cognitive functions. The exact function of the basal ganglia is something that is still being studied and observed, though it has been determined that the area plays some part in disease, including Parkinson's Disease and Huntington's Disease. Both of these diseases affect the motor control areas of the brain.

Along with the assistance that the basal ganglia gives to the body's movements, it also plays a factor in a number of cognitive processes. The area has a number of pathways that loop not only through the basal ganglia, but also through the prefrontal association cortex and the limbic cortex. Studies show that these loops and connections play a role in choosing or enabling a number of cognitive, emotional and executive functions in the brain.

This area of the brain, located at the base of the forebrain near the thalamus, also plays an important role in memory function in the human brain. People with disorders of this part of the brain have issues with memorization and probability tasks. Due to the basal ganglia being connected to the cerebral cortex, thalamus and brainstem, the area is found to play a part in numerous function in the body, many of which are still being learned about.

    What is the function of an earthworm's ventral nerve cord?

    A:

    An earthworm's ventral nerve cord carries signals from the brain to the body and allows for the coordination of the ganglia in each segment past the fourth. Ganglia are clusters of nerve cells, and an earthworm's brain is an organ made from the fused ganglia of the first three segments.

    A:

    A bilateral lacunar infarct refers to a stroke that damages deep brain structures, for example the thalamus, the basal ganglia or the pons, in both hemispheres of the brain, according to Drugs.com. It occurs when one of the arteries carrying blood to these areas becomes blocked.

    What is the function of the cerebellum?

    A:

    The cerebellum is the center of motor control within the brain, according to Healthline. It receives sensory information from the various sensory organs and the spinal cord and coordinates the body's movements. The cerebellum is responsible for speech, balance, coordination and posture, and it's the developmental center for learning motor coordination within the human body.
