In other words for biological psychologists it is crucial to know how body functions, human behavior, emotions can be directed to the brain work. Biological psychology is a very broad direction which incorporates data received from biochemistry, genetics, neuroscience, psychopharmacology to determine biological nature of the processes of human psyche. Biological psychology incorporates scientific data about hormones and neurotransmitters, genetic information and heritability apart from data received by its own methods which concerns electric signals in brain and chemical reactions. Due to the fact that behavioral neuroscience is based on scientific research only, its fields of study are limited to those subjects that can be controlled (Kalat, 2011).
Biological psychology studies human psyche in broad perspective-it aims to receive quantitative data that could be generalized and applicable for all humanity. Thus, it is possible to suggest that acquires information about the work of the brain applicable across populations. Thus the results achieved in the course of research are applicable to many. For instance scientific data about certain psychological problems, such as Alzheimer’s disease, schizophrenia, help to understand the nature of the diseases more adequately and gave new impact to pharmacology.
Today mental illnesses are regarded from biological perspective and pharmaceutical treatment that includes restoration of chemical balance is used along with psychotherapeutic methods. (Dewsury, 1991). Biological psychology uses different methods of research but the only condition of all the methods is biological variable during experiments. Among the methods most often used there are the following: disabling or decreasing of neural function, enhancing neural function, measuring neural activity and genetic techniques. As most of these experiments require intrusion into neural system mice, rats and non-human primates are involved.
Disabling of neural function is most often performed with the help of lesions, transcreanial magnetic stimulation or pharmacological manipulations during which the work of some part of the brain is intentionally altered or damaged to trace which behavior changes it will produce (Breedlove et al. , 2007). Improving neural functions is performed with the help magnetic or electromagnetic influence. Later researches try to figure out what human functions were improved with the help of this enhancement. The main areas of interest of biological psychology are the following: motivation, control, memory, perception, movement, and learning mechanisms however, it aims to expand its fields of study.
