It is the control center of the nervous system. The brain is located in the head. Controls and coordinates most of the movements, reactions, and homeostatic body functions such as heartbeat, blood pressure, fluid balance and body temperature. The functions of the brain responsible for awareness, feeling, memory, motor learning and other types of learning.
Brain, together with the heart, is one of the two most important organs of the human body. Stopping the operation of this body is a definition of death. The brain is the subject of scientific study of some areas - neuron-science, psychology, neurology, psychiatry, cognitive science.
Problems with the brain
• Brain injuries can affect large parts of the brain, sometimes causing significant loss of intelligence, memory and control of the body. • Head trauma caused by car accidents or other blows the skull are the leading cause of death. Often in these cases, more damage occurs due to swelling or edema of the brain as the injury itself. • Heart attack caused by blocked blood vessels in the brain, is another major cause of death and brain damage. • Other problems of the brain: neuro-degenerative diseases - Alzheimer's, Parkinson's disease, Huntington's disease, mental illness - clinical depression, schizophrenia, bipolar disorder, post-traumatic stress disorder, viral and bacterial infections of the meninges (meningitis), brain diseases caused by slow vortex Neuroinfections (Kuru, Creutzfeldt - Jakob disease, most commonly after eating sheep or beef, there is a gray sponge degeneration of the cerebral cortex), congenital disorders - Tay-Sachs disease, frailty X syndrome, Down syndrome, Tourette's syndrome.
Memory is a feature of the human mind, the ability to retain information. One of the most important parts of the brain in the process of remembering the hippocampus. Learning and memory are attributed to changes in neuronal synapses (connections). There are different types of memory-based classification for the duration, origin and locate the data obtained.
The basic stages of search and memory are encoding, storage and retrieval reminiscence.
Types of memory
There are three types of memory in relation to duration - sensory memory, short-term memory and long-term memory.
Sensory memory corresponds approximately to the initial moment of data acquisition. Some of this information in the sensory area continues to sensory memory, which is defined as short-term memory. These memories are generally characterized by strictly limited capacity and duration, while the stored information can be re-searched in general for some time; this type of memory is called long-term memory.
There are two types of memory depending on the type of information - declarative (explicit) and procedural (implicit) memory.
Declarative memory requires conscious recollection in these conscious processes must be triggered by the information again and again. Procedural memory is not based on conscious remembering information, but on implicit learning.
Most of the knowledge, to simultaneously come to mind with the study of memory disorders. Memory loss known as amnesia. By studying its various forms has been revealed a clear defect in memory subsystems of an individual brain and thus assume its function in normal brain functioning.
