Basal Ganglia

Submitted by kmydosh on Wed, 12/06/2017 - 11:44

There are two loops in the basal ganglia that focus activation onto specific areas of the motor cortex. The direct loop and the indirect loop function in different ways to regulate movement. In the direct loop  neurons of the globus are sponaneously active. These neurons are inhibitory. They keep the break on signals moving from the thalamus to the cortex. The globus neurons are constantly active and constantly keeping signals from traveling. The frontal cortex neuron is activating the globus neuron. In this way an inbibitor is inhibiting another neuron. This allows signals to pass trhough the cortex to a specific part of the cortex. The direct loop is essential for movement. The direct pathway through the basal ganglia activates the thalamus to initiate willed movements. In contrast, the indirect pathway inhibits the thalamus to supress unwanted movements.

Great paragraph with a lot of good information. Structured well, there is a clear subject sentence and closing sentence tieing all the information together. The only thing I would suggest is proof reading as there are a few spelling errors. Great work though!

Overall, great description. You give a lot of important information in a short amount of words. With that being said, I think some of your sentences are a little too short, such as, "these neurons are inhibitory," and, "the direct loop is essential for movement". I would personally include these at the end of the sentences before them, if possible. 

Your paragraph was well organized and had a very good flow to it. There are a few spelling errors, but other than that, great job!
