The gut–memory connection is the relation between the gastrointestinal tract and memory performance. The phenomenon of the gut–memory connection is based on and part of the idea of the gut-brain axis, a complex communication network, linking the central nervous system to the gut.
Sensory information is stored in sensory memory just long enough to be transferred to short-term memory. [1] Humans have five traditional senses: sight, hearing, taste, smell, touch. Sensory memory (SM) allows individuals to retain impressions of sensory information after the original stimulus has ceased. [2]
Liking refers to the palatability or taste of the food, which is reduced by repeated consumption. Wanting is the motivation to consume the food, which is also reduced by repeated consumption of a food [11] [12] and may be due to change in memory-related processes. [13] Wanting can be triggered by a variety of psychological processes.

The taste is commonly related to other, more negative, tastes such as bitter and sour due to how unpleasant the taste is for humans. Richard Mattes, a co-author of the study, explained that low concentrations of these fatty acids can create an overall better flavor in a food, much like how small uses of bitterness can make certain foods more ...
Gustatory recognition memory, or the recognition of taste, is correlated with activity in the anterior temporal lobe (ATL). [67] In addition to brain imaging techniques, the role of the ATL in gustatory recognition is evidenced by the fact that lesions to this area result in an increased threshold for taste recognition for humans. [68]
These specific models have been able to address the consumptive side of BN, and have proven to be useful for testing drug effects on intake behavior. Due to the pharmacological response differences between rodents and humans, new drug development has been concentrating on drug testing specifically in human subjects. [89]
Neuromodulation exists in the olfactory system and is responsible for neural plasticity and behavioural change in both mammals and insects. [4] In the context of olfactory memory, neuromodulators regulate storage of information in a way that maintains the significance of the olfactory experience. [4]
