hippocampal location-selectivity ("place cell activity") as well as place-independent behavioral correlates and sensory-triggered discharges are demonstrated to have common features: (1) abstraction, that is, development within the hippocampal circuit of novel, cue-invariant supramodal representations; (2) varying degrees of generalization or specificity; (3) capacity for abrupt changes in discharge correlates of individual neurons as the animal changes its behavior pattern or its environment changes dramatically; (4) though individual neurons discharge when the subject occupies a certain place, or performs a certain behavior, the ensemble of hippocampal neurons comprehensively represent the whole environment and all behaviors required for the task at hand. |

| L Waterhouse, D Fein, C Modah. Neurofunctional mechanisms in autism. Psychological review. vol 103. issue 3. 1996-10-16. PMID:8759044. |
behavioral impairments in autism are theorized to result from abnormal neuronal organization in brain development generating 4 systemically related neurofunctional impairments: (a) canalesthesia, wherein abnormal hippocampal system function "canalizes" sensory records, disrupting integration of information; (b) impaired assignment of the affective significance of stimuli, wherein abnormal amygdaloid system function disrupts affect association; (c) asociality, wherein impaired oxytocin system function flattens social bonding and affiliativeness; and (d) extended selective attention, wherein abnormal organization of temporal and parietal polysensory regions yields aberrant overprocessing of primary representations. |

recordings were made from single neurons in the hippocampus and parahippocampal gyrus while macaques were moved on a platform mounted on a free-moving robot or on wheels in a cue-controlled 2 m x 2 m x 2 m environment, in order to investigate the representation of space and of spatial memory in the primate hippocampus. |

the representations of space provided by hippocampal view-responsive neurons may be useful in forming memories of spatial environments (for example, of where an object has been seen and of where the monkey is as defined by seen views) and, together with whole-body motion cells, in remembering trajectories through environments, which is of use, for example, in short range spatial navigation. |

the findings indicate: (1) the hippocampus and caudate nucleus selectively mediate expression of place and response learning, respectively (2), in a visually cued extramaze environment, hippocampal-dependent place learning is acquired faster than caudate-dependent response learning, and (3) when animals shift to caudate-dependent response learning with extended training, the hippocampal-based place representation remains intact. |
