What functions are controlled by the brain?

Cerebrum is the largest part of the human brain, composed of two hemispheres and four main parts of the brain. When introducing the human brain it is generally the brain that comes to mind. Everything that is not controlled by the brain stem and brain is controlled by the brain. Without brain, sight, odors, movement, muscle control and even the ability of a complex choice would not be possible. This area of ​​the brain is used not only as the main surface of the brain, but also controls functions such as vision and engine response. Korttex has four areas or "lobes", known as frontal, parietal, occipital and temporary. These lobes determine how one perceives and responds to sensory data, emotional reactions, orientation, memory and speech skills.

The limbic system processes other handles of epohyba more specifically than the bark and consists of thalamus, amygdala, hippocamp and hypothalamus. Hypothalamus processes feelings like hunger and thirst and controls the pituitary gland, which is responsible for growth. Amygdala regulates feelings such as fear or anxiety. Hippocampus processes the abilityTransform short -term learning into long -term memory, while Thalamus primarily transfers sensory data to the cortex.

Unlike the feeling and data from touch, taste, hearing or sight, the scents are directed part of the brain known as the olfactory bulb . It is this small system that allows people to tell people's strong fragrances from the weak, distinguish odors apart and cover the general scents to focus on specific, important. The non -functional olfactory bulb can be responsible for the reduced sense of smell, because it is the system that transfers the information from the nose to the brain.

Basal ganglia is located deep inside the brain brain structures. Indeed, the collection of cores that surround Thalamus and the limbic system are basal ganglia responsible for quite a lot, despite their small size. Voluntary movement, learning and motor behavior are controlled by basal ganglia. One interesting function of this part of the brain is the choice of action, which umIt brings a person to choose from several options. Mental disorders, such as obsessive forgiving and attention disorder with hyperactivity, are associated with non -functional basal ganglias, as well as engine management conditions such as Parkinson's disease.
