 Dear students, in this practical, you will learn about brain and its different areas eliciting behavior. Human brain is the most complex part of the body. This three-pound organ is the seat of intelligence, interpreter of senses, controller of behavior and initiator of body movement. Brain is like a group of expert. All the parts of brain work together, but each part of brain has its own responsibility. There are three parts of the brain, forebrain, midbrain and the hindbrain. Forebrain is the most developed part of brain. It consists of cell brain and different structures hidden beneath like thalamus, hypothalamus, pituitary gland and limbic system. Whenever people see a picture of brain or you can see here, that is the cerebrum that they notice. The cerebrum lies on the top most part of brain and the source of intellectual activities. It holds memories. It allows you to think and imagine. It also helps you to recognize your friends, read book and play games. Hemisphere is split into two halves, like as you can see here, it is split into two halves through our deep fissure and these two halves are known as hemisphere, so you can say that several hemispheres. Although both these hemispheres, there is a split between these hemispheres, but both these parts, both these hemispheres can communicate with each other through a thick track of nerve fibers that lies at the base of that slit or that fissure. Each of these hemispheres has been divided into four lobes, frontal lobe, parietal lobe, temporal lobe and here is the occipital lobe. Frontal lobe is responsible for some exacting functions such as GCN making, motor planning and impulse controller. The next is parietal lobe. Parietal lobe is responsible for some spiritual awareness and sensation. Temporal lobe, temporal lobe, it plays a key role in artery processing and memory and occipital lobe. Ocipital lobe is responsible for visual processing. Dear student, although both of these hemispheres are seem to be mirror image of each other, but they are different such as the part which is involved in formation, it lies in the left hemisphere and right part or right hemisphere is responsible for some abstract reasoning skills and here is the interesting thing that right hemisphere control your left side of the body and left hemisphere control your right side of the body. So both of these hemispheres control opposite sides of the body. It means if there is a damage in one part of brain, it affects the other side or other part of the body. So if there is a stroke in right hemisphere, then this will leave the right left leg and arm to paralyze. The next is mid-print. Mid-print lies at the top most of brainstem and it controls some impulse action and it is the center or it is a part of the circuit that control eye movement and voluntary action and last part is the hand-brain. Hand-brain it consists of upper part of spinal cord and brainstem and a ball of wrinkle tissues called cerebellum. This part of the brain it controls some basic and some important function of the body like respiration and heart rate. It also coordinate movement and involved in some learned motor movement. It means whenever you play a piano or you hit a ball, it means that you are activating your cerebellum. Dear student, now I will discuss different areas of brain that induce behavior. To design different experiments to investigate different behavior, different specific behavior, the participants are exposed to different stimulus or different toss that are associated with their specific behavior. Their brain activity is monitored through some neuro-imaging technique and a comparison is made between brain function during different conditions that are associated with your behavior of interest. So, first of all there is perifrental cortex. Perifrental cortex particularly the dorsal lateral perifrental cortex, it involves in some executive function like DCM making, impulse control and working memory. Next is parietal lobe or this area it is possible for some special awareness, attention and it is also responsible for integrative sensations. Next part or next area is temporal lobe. Temporal lobe, this part is responsible for artery processing, memory formation and language comprehension. Hippocampus is the major part of this area which is associated with memory formation. Next is amygdala, amygdala is like an almond shape structure which is present in temporal lobe and this part is involved in processing of emotions. For example, fear and threat detection. Next is occipital lobe, the visual cortex of occipital lobe is responsible for visual processing. It also allows us to recognize different objects and things. And the last area is stator, it is a part of basal ganglia and it is responsible for habit formation, reward processing and motor control. Dear students, by understanding the normal human functioning as well as how brain damage and disease affect behavior, emotions and feelings, researchers are able to come out with new ways of treating potential danger or disease that might arise. Thank you.
