| Hira E Shah, Nitin Bhawnani, Aarthi Ethirajulu, Almothana Alkasabera, Chike B Onyali, Comfort Anim-Koranteng, Jihan A Mostaf. Iron Deficiency-Induced Changes in the Hippocampus, Corpus Striatum, and Monoamines Levels That Lead to Anxiety, Depression, Sleep Disorders, and Psychotic Disorders. Cureus. vol 13. issue 9. 2021-10-26. PMID:34692346. |
the mechanisms of how iron deficiency affects behavior include affecting the hippocampus, the corpus striatum, and certain neurotransmitters. the hippocampus is a brain region that is essential for memory, learning, and other purposes. the hippocampus is very sensitive to lack of iron during early development. the corpus striatum dispatches dopamine-rich projects to the prefrontal cortex, and it is involved in controlling executive activities such as planning, inhibitory control, sustained attention, working memory, regulation of emotion, memory storage and retrieval, motivation, and reward. |

brain regions that show a significant change in activation following a rejection stimulus include cortical regions (cingulate, insular, orbitofrontal, and prefrontal), and subcortical regions (angular gyrus, hippocampus, striatum, tegmental area, and temporal pole) and correspond to (i) pain, distress, and memory retrieval; (ii) reward, romantic love, and dopaminergic circuits; and (iii) emotion regulation and behavioural adaptation. |

during the first 1-3 min of training for food reward, glucose levels in extracellular fluid (ecf) declined significantly in the hippocampus and striatum; the declines were not seen in untrained, rewarded rats. |

compared to untrained food controls, training with food reward resulted in significant glucose increases in the hippocampus but not striatum; striatal glucose levels exhibited large increases to food intake in both trained and untrained groups. |

after successfully establishing the conditioned place preference (cpp) paradigm to simulate the meth-associated reward memory in c57bl/6 mice, we observed that hn was significantly inhibited during meth (2 mg/kg, i. p.) administration and returned to normal after the extinction of meth cpp, as indicated by the immunostaining of bromodeoxyuridine (brdu) and doublecortin (dcx) in the hippocampus. |

using the relative reward value of cues to define continuous "paths" through an abstract value space, we show that single neurons in primate hippocampus encode this space through value place fields, much like a rodent's place neurons encode paths through physical space. |
