The Main Parts of the Brain and Their Functions The brain is the center of our bodies intelligence. Many people do not know much about the brain. The brain achieves task to keep us alive and to function properly. The brain is made up of many parts that each perform different task. In the past, there was a large controversy concerning if different parts of the brain, did different things or if all areas of the brain were equally important and equally utilized for mental activity. Strong evidence came around in 1806, when Paul Broca performed an autopsy on a patient and it confirmed that different regions of the brain perform different task. Broca’s patient had major damage to his left frontal region which impaired his speech. This region …show more content…
The most popular imaging method used today is the functional magnetic resonance imaging, also known as fMRI. This machine detects mental activity while the patient is doing a mental task or exercise by observing the blood’s oxygen level in the brain (Grison, Heatherton, & Gazzaniga, 2015). There are 3 large sections of the brain, that all hold different parts of the brain that perform different things. The three main regions of the brain are the Hindbrain, the Midbrain and the Forebrain. The Hindbrain is made up of two parts, the Cerebellum and the Brainstem. The Hindbrain is most commonly used for survival functions. The Midbrain is made up of the Substantia Nigra and this region is known to control movement of the body. The Forebrain is separated into two different sections, the Subcortical structures and the Cortical Structures. The Subcortical structures consist of the Thalamus, the Hypothalamus, the Hippocampus, the Amygdala and the Basal Ganglia. The Cortical structures consist of the Occipital lobes, the Parietal lobes, the Temporal lobes, and the Frontal lobes. The Forebrain is linked to motivation, emotion and complex thought (Zimbardo, Johnson, & McCann, 2012). The brain is an incredibly complex …show more content…
One of the major structures included in the Midbrain is the Substantia Nigra. The Substantia Nigra is involved in making voluntary movements as well as initiating movements. Voluntary movements are movements that can be stopped if wanted, such as reading a book and when finished with a page you turn to the next, or while reading your eyes are moving with the words. This sections of the brain are mandatory for the production of dopamine. Dopamine is a neurotransmitter that is responsible for behavior and general motor function. If the Substantia Nigra’s cell die, dopamine is not produced by the cells like need and this causes Parkinson’s disease (Grison et al., 2015). Above the Midbrain is the Forebrain, and it is divided into two main
