What is the lower frontal gyrus?
gyrus and sulcus are terms used to describe brain anatomy. The brain tissue is folded on top of each other; The upper part of the fold is known as Gyrus and the trough is called sulcus. The lower front gyrus forms part of the frontal brain brain. If the human brain is visible from the side, it can be said that it roughly resembles a boxing glove or glove. Looking at it, the lower front Gyrus would be satisfied in the large part of the "glove" immediately above the independent area of the thumb.
There are three anatomical areas in the lower frontal gyru. PARS OpeCularis is a front or most powerful area and is roughly associated with brain mapping Brodmann Area 44, also known as the Broca area. Pars triangularis lies behind the PARS OpeCularis and corresponds to the Brodmann region 45. Finally, PARS orbitalis is the rear limit of the lower frontal gyrus and is connected with the Brodmann Area 47. The whole area receives its blood supply from the middle cerebral artery.
Scientists continue to discover the functions of this area of the brain, many of which are related to our ability to live socially and communicate with others. The study of the Jabbi and Keysers has shown the connection of the lower frontal gyro in our interpretations of the facial expressions and the corresponding emotional reaction suitable for expression. Another study in the European Neuroscience magazine identified damage or stimulation specific to the pars opecularis as a disruption of normal language production. Another experiment was combined by pars opecularis with observation and imitation of appropriate behavior, which is the ability that autistic children have difficulty in performing.
It seems that some behavior is related to the left or right lower front gyr. The study in the magazine neuroscience shows the correlation between the avoidance of serial behavior and greater excitation in the lower right front gyru. Conversation seems to be combined: more risky choices and behavior proven patients with lesions or injuries on the right gyro. Function -specific functionGyrus includes many language -related tasks. It seems that part of the human ability to understand syntax and syntactic processing and the overall understanding of the language is found in this area. More studies have the overall continuity of language in this area.
