after identifying neuron activity in the hippocampus ca1 region specific to multi-modal stimuli that predicted appetitive and aversive unconditioned stimuli (conjunctive stimulus encoding), the authors showed that neurons located in the anterior cingulate cortex dynamically encode the discrete sensory features of the outcome-predictive stimuli during training, and these highly specific feature-based projections can excite or inhibit conjunctive-coding neurons in the hippocampus during retrieval. |

it was found that in addition to changes in the expression of immediate early genes c-fos (in all studied hippocampal fields) and arc (in dorsal and ventral ca1, as well as in dorsal dentate gyrus), exposure to a new context significantly altered expression of the insulin receptor substrate 2 gene (irs2) in dorsal ca1 and ventral dentate gyrus irrespectively of the negative reinforcement, which suggests participation of the insulin/igf system in the early stages of neural activation during learning. |
