TL;DR: Experimental diabetes showed clear signs of changes in the dentate gyrus, changes similar to those present in the aging process, in line with a reduced performance in learning and memory tests.

TL;DR: Data suggest a modulating role for histamine in learning and motivation/emotionality processes in the rat brain and suggest that histamine sensitive sites in hippocampus and the nucleus accumbens have a role in these processes.

TL;DR: Evaluating if histaminergic neuron circuits have participation on the consolidation processes of the conditioned avoiding response showed that histamine treatment interfered with the consolidation of the avoiding response, affecting latency and the memory efficiency, which supports the concept that Histamine neurotransmission modulates learning and memory by affecting selectively the three stages of learning.

TL;DR: Data suggest that POA is linked to the ipsilateral HPC through histaminergic influence to control behavioral patterns induced by novelty, and shows that HA in POA exerted an inhibitory influence on general motor behaviors and also on goal-directed activity.

TL;DR: Evidence support the lateralized participation of the amygdala on exploratory behaviour and histamine neurons appear to mediate part of these differential modulations.
