The frontal lobe is a very important section of the human brain; it is actually the distinguishing factor that sets human beings apart from all the other animals. The frontal lobe is carries out several functions such as fine motor control, maintaining human memory and social interaction. The frontal lobe controls many of the functions that make the functioning of human beings to be unique. It is therefore important to understand all the underlying concepts that are important to the functioning of the frontal lobes and how the frontal lobes are used to shape the future of the human beings (Duncan, 1995).
The frontal lobe helps the human beings by performing functions such as making the human beings aware of the future consequences of the actions that they carry out at the present time, the ability to choose and distinguish between the good and bad things and the ability to recognize and avoid any behavior that is considered as being socially unacceptable. Therefore is important to ensure that during the teen years, the frontal cortex matures as it is the ultimate determinant of the cognitive functions of an adult (Goldberg & Bilder, 1987). There are however patients who suffer problems that are related to memory as a result of some disorders or dysfunctions that are related to an effect on the functioning of the frontal lobes. These functions which may be inhibited by the development of the frontal lobes and cause memory related problems include the following:
The Short term Motor Memory
It is of great importance and essence to understand the functioning of the frontal lobes and the roles that they play in the process of influencing the short term motor memory. This will help to determine whether a person who is suffering from a short term memory loss has problems that are related to the frontal lobes; a thorough investigation and research on the effect of the frontal lobes on the short-term motor memory is crucial to enabling the medical practitioners to determine the causes of the short term memory loss, how it is associated with the frontal lobes as well as how to help these patients to overcome the problems that they are faced with (Petrides & Pandya, 1994).
The short term memory focuses on the action that is taking place at the present time; it is important to consider the functioning of the frontal lobes in relation to the short-term memory because it determines how a person prepares a plan of action to undertake an activity and how this is related to the functioning of a small section of the long-term memory. Since memory is one of the executive functions performed by the brain; it is important to understand the performance of the frontal lobes in relation to the functioning of the short term memory. The comparison between the plan of action of an organism and the long-term memory is essential in giving an indication of the memories that an individual seeks to use in to developing a plan of action for a given activity (Duncan, 1995). This will help to determine whether the individual uses the right memories to prepare a plan of action for a given activity.
The mechanism for the memories used to prepare a plan of action are still under development and a research needs to be done to ensure that the future functioning of the frontal lobes in the control of the short term memory is well understood; this process is determined by a system referred to as contingent negative variation. In the process of developing and implementing a planned plan of action, a surface potential develops over the frontal lobe. There is also the readiness potential, which enables the brain to produce the charge clearance (Petrides & Pandya, 1994).
The motor memory cells look into the future action; however in contrast, the working memory cells look backwards at sensory functions that will determine the actions that are yet to take place. The rate at which the working memory cells are discharged is reduced as the event that is being considered nears and this causes an inhibitory effect that will have an influence on the planned motor pathway. In the process of utilizing the working memory, it is important to store information while at the same time carrying out the function of processing the other sensory functions. It is important to understand the role of the frontal lobes in the working memory function (Goldgerg & Bilder, 1987).
Any damage to the prefrontal lobes can result into a condition known as a short term memory loss; the effects associated with the working memory neurons have a great impact on the human thought. The working memory cells are a very important part of the day to day functions of the human beings; they control the speech as they invoke the words that are to be spoken as well as the plans for the future events. Therefore it is very important to understand the working of these memory cells and how any damage to them can affect the memory cycle so as to ensure a panned mental development cycle is achieved.
For the planned action to take place as scheduled, there are several types of interference that that take place in the prefrontal cortex that will need to be suppressed. This interference results from waves of strong memory or instincts which will need to be inhibited to ensure that the actions that take place are controlled. This interference is carried out by the inhibitory control pathways, which are in the prefrontal cortex (Petrides & Pandya, 1994). It is therefore important to understand how these inhibitory functions take place and how they can be controlled so as to ensure that the inhibitory functions take place as scheduled and that they are well controlled.
The frontal lobes are an important part of the human nervous system and need to be carefully controlled in their operations. It is therefore important to understand all the key aspects that are pertinent to the functioning of the frontal lobes as well as the disorders as dysfunctions that can result to the damages on any part of the frontal lobes. Of particular importance is the memory functions of the frontal lobes and the processes involved in the carrying out of these functions so as to determine the ultimate functioning of the frontal lobes and how these functions can be understood and improved in the future.
