SPOILAGE BACTERIA AND QUALITY INDEX METHOD SCORE IN REARED GILTHEAD SEABREAM

open access: yesItalian Journal of Food Safety, 2008
A model to predict the Quality Index Method (QIM) score increase during the storage was set for Sparus aurata. In this regard, 126 specimens were analysed during the storage in ice, enumerating the spoilage bacteria in Iron Agar as well as evaluating the

Interactions between the amygdala and medial prefrontal cortex as upstream regulators of the hippocampus to reconsolidate and enhance retrieved inhibitory avoidance memory

open access: yesMolecular Brain, 2021
Memory reconsolidation is thought to maintain or enhance an original memory or add new information to the memory. Retrieved inhibitory avoidance (IA) memory is enhanced through memory reconsolidation by activating gene expression in the amygdala, medial ...

Limbic Tract Integrity Contributes to Pattern Separation Performance Across the Lifespan. [PDF]

open access: yes, 2014
Accurate memory for discrete events is thought to rely on pattern separation to orthogonalize the representations of similar events. Previously, we reported that a behavioral index of pattern separation was correlated with activity in the hippocampus ...

Different behavioral strategies of two sympatric seahorses: habitat availability and increased density of Hippocampus guttulatus alter the behavior of Hippocampus hippocampus

open access: yesFrontiers in Marine Science, 2023
In the light of future ocean warming scenarios and habitat fragmentation, coastal fishes must adjust their physiological and behavioral traits to face the combined effect of global warming and ecological interactions.

Genetic Differences in Dorsal Hippocampus Acetylcholinesterase Activity Predict Contextual Fear Learning Across Inbred Mouse Strains

open access: yesFrontiers in Psychiatry, 2021
Learning is a critical behavioral process that is influenced by many neurobiological systems. We and others have reported that acetylcholinergic signaling plays a vital role in learning capabilities, and it is especially important for contextual fear ...
