caption_attribution_description: inferior frontal gyrus.
context_page_description: The inferior frontal gyrus, is the lowest positioned gyrus of the frontal gyri, of the frontal lobe, and is part of the prefrontal cortex.
  Its superior border is the inferior frontal sulcus, its inferior border is the lateral sulcus and its posterior border is the inferior precentral sulcus. Above it is the middle frontal gyrus, behind it is the precentral gyrus.
  The inferior frontal gyrus is the location of Broca's area, which is involved in language processing and speech production.
context_section_description: The inferior frontal gyrus (IFG), (gyrus frontalis inferior), is the lowest positioned gyrus of the frontal gyri, of the frontal lobe, and is part of the prefrontal cortex.
  Its superior border is the inferior frontal sulcus (which divides it from the middle frontal gyrus), its inferior border is the lateral sulcus (which divides it from the superior temporal gyrus) and its posterior border is the inferior precentral sulcus. Above it is the middle frontal gyrus, behind it is the precentral gyrus.
  The inferior frontal gyrus is the location of Broca's area, which is involved in language processing and speech production.
