What is the connection between prefrontal bark and memory?

Prefrontal bark is found in the cortical areas of the frontal lobe of the brain and is assumed that it is involved in behavior such as perception, memory, judgment and justification, as well as the expression of social behavior and personality. There is a connection between prefrontal bark and memory, because this part of the brain seems to play a key role in checking work or short -term memory. Precise brain work must still be revealed, but imaging technology has led to an increase in the knowledge of the processes involved in memory. Research of short -term memory disorders, such as schizophrenia, plunged light on the connection between prefrontal bark and memory.

neurologists work based on the fact that there are two types of memory-long and short-term memory. Short -term or working memory is information that is used at the same time. The information is first collected by the senses and it is temporarily in sensory memory. If a picture is a sensory memory is concentrated on more than eight seconds, the stimulus is coded into a short -term memory. What's the hundredNot with memory after depending on how the information is processed-lze is to practice or repeat, stored in long-term memory or lost.

The connection between prefrontal bark and memory is that is still being investigated, although since the first use of advanced imaging techniques in 1997, great progress has been made in 1997 when the brain holds sensory stimuli in work memory and then activity involved in downloading this information. Since there are no real physical changes in synaptic connections involved in short -term memory, it is difficult to determine whether working memory is in nature or dynamic. In the earlier theory, short -term memory would be created by temporary changes in synaptic transmissions, while in the second theory the memories are kept electrically in a loop and form the perimeter of feedback.

Due to the connection between prefrontal bark and memory, especially working memory, any damage to the former is likely to be impaired. The functions of this part of the brain include planning, attention and decision -making and organization of distributed information contained in the nervous system. Within the prefrontal bark, high concentrations of nerve fibers containing dopamine, neurotransmitter, which transmits neurons reports through synapses, an integral part of the processes determining working memory.
