The cerebrum is considered the largest part of the brain it performs some roles like that of interpretation of tactile sensation, vision, various kinds of learning, etc. It’s divided into two halves one is called the left hemisphere and the other is called the right hemisphere. The right one functions to control all the functioning of the left side of the body and the left part controls the right part of the body. They have defined roles to perform such as: Right hemisphere: it involves reasoning for example spatial reasoning, mechanical skills, it also involves perception, emotions about arousals, etc. It deals with maintaining balance, comprehending the situation as a whole, muscle movement, it also functions to control the immune system of human, its also accountable for heartbeats, digestive system, etc. Left hemisphere: it deals with language learning, attention, positive emotions, etc. this part is also called the digital brain, it deals with logic, math, thinking writing, doing sequential tasks, keeping things in order, computing, verbal skills, etc. These two parts of the brain are joined by a thick band called the corpus callosum. The role of the corpus callosum is to keep these parts connected and at the same time, it functions to make these parts share the concerned information. People cannot be generally dominated on both parts i.e. only one half of the brain is dominant either left or right it’s said that people whose left half is dominant have analytic nature and those who are having right-side dominant are usually creative by nature. The surface of the cerebrum is called the cortex. It consists of neurons. As far as its appearance is concerned, it had fold like appearance, and these folds are called a gyrus.
Hypothalamus and endocrine system:
The endocrine system is called the ductless gland they are responsible for the secretion of hormones directly into the bloodstream. The major gland making up the endocrine system are Adrenal glands; these produce two hormones they are cortex and adrenaline thyroid glands producing the hormones called thyroxin; parathyroid glands; pituitary glands also called master glands as they mostly affect other glands to produce hormones such as growth hormones; sex glands secreting sex hormones; hypothalamus which joins the ductless gland that is endocrine system to nervous system. The limbic system is the structure in the brain dealing with the emotions, rewards, learning, learning, hunger, thirst hormonal secretions itâ€™s the place for conscious as well as unconscious function it connects bodily and mental experiences. The four major components are the hypothalamus, the amygdala, the thalamus, and the hippocampus. Hypo campus and some associated structures play an important role in memories. Amygdala is placed in the temporal lobe and has an important role in emotions. Hypothalamus is the center of the limbic system it’s connected to the frontal lobe. It secretes hormones which in turn play a big role in pleasure and on the other hand helps to regulate the autonomic nervous system (ANS). The limbic system is also coupled with the prefrontal cortex. As per some of the scientists, this sort of link is related to pleasure which is gained when a person solves some problem. It interacts with the cerebral cortex which is in return connected to emotions, memories, cognitive shortcomings. It has also served many other functions such as sensory processes, consciousness, and impulses.
