41. In the human it is a narrow band located in the isthmus of cingulate gyrus . 42. This suggests a potential link between the lingual gyrus and hippocampal regions in the brain. 43. Sources could also include one from the right opercular part of the inferior frontal gyrus . 44. Reelin and Notch1 cooperate in the development of the dentate gyrus , according to another. 45. Collectively the dentate gyrus , CA1 and CA3 of the hippocampus compose the trisynaptic loop. 46. In a normal situation, the granule cells in dentate gyrus should be tightly packed. 47. When they lied, a portion of the brain called the anterior cingulate gyrus was activated. 48. At least four separate, anatomically distinct sensory homunculi have been identified in the postcentral gyrus . 49. Broca s aphasia is indicative of damage to the posterior inferior frontal gyrus of the brain. 50. Aldosterone, probably acting through mineralocorticoid receptors, may positively influence neurogenesis in the dentate gyrus .
