TheBrain and Biopsychology
Tounderstand the dynamics of the brain and the mind, it is important toknow its regions and their functionalities. The cerebrum is the partresponsible for controlling movement. The cerebrum through cerebralcortex also performs the memory function and analyzing the sensorydata. It also believed to make decisions and form thoughts (Freeberg,2009).The left hemisphere is the region where information is interpretedlogically and languages are formulated alongside production ofsymbolic information. The right hemisphere region is responsible forthe multi-sensory, especially the visual processing skills (Breedloveet al, 2007).The cerebellum part is responsible for controlling balance and thecoordination functions of the brain. The brain stem connects thebrain with the spinal cord and is responsible for controllingbreathing, heart rate, blood pressure and digestion among otherautomatic processes of the body (Freeberg,2009).
Themind-brain problem is a problem of understanding the mind and thenature of consciousness. While the brain is not identical to themind, its activities are linked with the nature of consciousness thatis enhanced by the mind (Freeberg,2009).This is the basis of the debate that monists believe that the mindand the brain is the same thing, while dualists assert that the twoare different. In this debate, I take a dualist view that the mindand the brain are different in existence. This is because I believein the Mind/Brain theory. According to the Mind/Brain Identitytheory, the processes of the mind are the same with the nature ofconsciousness and processes of the mind (Freeberg,2009).However, I believe that the two are not identical.
Toexplore and understand the brain functions its processes, there aredifferent research tools and methods that have been used. One of themethods is lesions, which involves the destruction or removal of theparts of the brain. By removing certain parts, scientists learn whatfunction they carry (Weathingtonet al, 2010).Another method is the use of imaging equipment to map out thedifferent parts of the brain. Some of the imaging solutions used are,the ComputerizedAxial Tomography(CT) scan, Magnetic Resonance Imaging (MRI), Functional MRI and thePositronEmission Tomography (PET) scan(Weathingtonet al, 2010).Inaddition, another method used is theElectroencephalogram,EEG, which involves analysis of the electric activity of the brain(Weathingtonet al, 2010).
Togain the knowledge about the brain that is known to date, there arevarious research methods that are employed. One of the methodologiesis experimenting method. This involves disabling or limiting theneural function to study the biological and behavioral processes thatare affected (Weathingtonet al, 2010).The other methodology used is observation method that involvesobserving, recording and analyzing the behavior of the subject beingstudied. Moreover, research methods use genetic techniques that seekto infer the genetic aspects of the biological psychology(Weathingtonet al, 2010).
Inconnection with the research about the brain and studyingbiopsychology, there are fundamental ethical concerns. One of theethical concerns is the destruction of some parts of the brain of thesubject to study its brain (Bernat,2008).Some animals used in the study such as rats have their partscompletely destroyed in order to study the functions of the brainparts destroyed. Another ethical concern is that the studies done onanimals are used to generalize the knowledge to include people as ifthe two subjects were equal (Bernat,2008).Moreover, people have argued about the need to understand the brainfunctions and questioned the methods used as if the research was ofreal necessity.
