assessing recent and remote associative olfactory memory in rats using the social transmission of Food Preference paradigm
Nature Protocols, 2017Co-Authors: Benjamin Bessieres, Olivier Nicole, Bruno BontempiAbstract:Rats have the ability to learn about potential Food sources by sampling their odors on the breath of conspecifics. Although this ethologically based social behavior has been transposed to the laboratory to probe nonspatial associative olfactory memory, only a few studies have taken full advantage of its unique features to examine the organization of recently and remotely acquired information. We provide a set of standardized procedures and technical refinements that are particularly useful in achieving this goal while minimizing confounding factors. These procedures, built upon a three-stage protocol (odor exposure, social interaction and Preference test), are designed to optimize performance across variable retention delays, thus enabling the reliable assessment of recent and remote memory, and underlying processes, including encoding, consolidation, retrieval and forgetting. The different variants of the social transmission of Food Preference paradigm, which take a few days to several weeks to perform, make it an attractive and versatile tool that can be coupled to many applications in CNS research. The paradigm can be easily implemented in a typical rodent facility by personnel with standard animal behavioral expertise.

wistar rats and c57bl 6 mice differ in their motivation to seek social interaction versus Food in the social versus Food Preference test
Physiology & Behavior, 2020Co-Authors: Christina J Reppucci, Leigha A Brown, Ashley Q Chambers, Alexa H VeenemaAbstract:Here we characterized the Social versus Food Preference Test, a behavioral paradigm designed to investigate the competition between the choice to seek social interaction versus the choice to seek Food. We assessed how this competition was modulated by internal cues (social isolation, Food deprivation), external cues (stimulus salience), sex (males, females), age (adolescents, adults), and rodent model (Wistar rats, C57BL/6 mice). We found that changes in stimulus Preference in response to the internal and external cue manipulations were similar across cohorts. Specifically, social over Food Preference scores were reduced by Food deprivation and social familiarly in Wistar rats and C57BL/6 mice of both sexes. Interestingly, the degree of Food deprivation-induced changes in stimulus investigation patterns were greater in adolescents compared to adults in Wistar rats and C57BL/6 mice. Strikingly, baseline stimulus Preference and investigation times varied greatly between rodent models: across manipulations, Wistar rats were generally more social-preferring and C57BL/6 mice were generally more Food-preferring. Adolescent Wistar rats spent more time investigating the social and Food stimuli than adult Wistar rats, while adolescent and adult C57BL/6 mice investigated the stimuli a similar amount. Social isolation did not alter behavior in the Social versus Food Preference Test. Together, our results indicate that the Social versus Food Preference Test is a flexible behavioral paradigm suitable for future interrogations of the peripheral and central systems that can coordinate the expression of stimulus Preference related to multiple motivated behaviors.

wistar rats and c57bl 6j mice differ in their motivation to seek social interaction versus Food in the social versus Food Preference test
bioRxiv, 2020Co-Authors: Christina J Reppucci, Leigha A Brown, Ashley Q Chambers, Alexa H VeenemaAbstract:Here we characterized the Social versus Food Preference Test, a behavioral paradigm designed to investigate the competition between the choice to seek social interaction versus the choice to seek Food. We assessed how this competition was modulated by internal cues (social isolation, Food deprivation), external cues (time-of-testing, stimulus salience), sex (males, females), age (adolescents, adults), and rodent model (Wistar rats, C57BL/6J mice). We found that changes in stimulus Preference in response to the internal and external cue manipulations were similar across cohorts. Specifically, social over Food Preference scores were reduced by Food deprivation and social familiarly in Wistar rats and C57BL/6J mice of both sexes.

Adolescent Wistar rats spent more time investigating the social and Food stimuli than adult Wistar rats, while adolescent and adult C57BL/6J mice investigated the stimuli a similar amount. Neither social isolation nor time-of-testing altered behavior in the Social versus Food Preference Test. Together, our results indicate that the Social versus Food Preference Test is a flexible behavioral paradigm suitable for future interrogations of the peripheral and central systems that can coordinate the expression of stimulus Preference related to multiple motivated behaviors. HIGHLIGHTSO_LIRats prefer social over Food when sated, and this is attenuated by Food deprivation. C_LIO_LIMice have no Preference when sated, and prefer Food over social when Food-deprived. C_LIO_LIRats prefer a familiar social stimulus or a novel social stimulus over Food. C_LIO_LIMice prefer Food over a familiar social stimulus. C_LIO_LIAdolescent rats investigate social and Food stimuli longer than adult rats.

insights into Food Preference in hybrid f1 of siniperca chuatsi siniperca scherzeri mandarin fish through transcriptome analysis
BMC Genomics, 2013Co-Authors: Shanan He, Xufang Liang, Lingling Li, Ying Yu, Wei Huang, Chunmei QuAbstract:Background As economically relevant traits, feeding behavior and Food Preference domestication determine production cost and profitability. Although there are intensive research efforts on feeding behavior and Food intake, little is known about Food Preference. Mandarin fish accept only live prey fish and refuse dead prey fish or artificial diets. Very little is currently known about the genes regulating this unique Food Preference.

insights into Food Preference in hybrid f1 of siniperca chuatsi siniperca scherzeri mandarin fish through transcriptome analysis
BMC Genomics, 2013Co-Authors: Xufang Liang, Wei Huang, Jiandong Sun, Liang Cao, Xiaoli Bai, Yaxiong TaoAbstract:As economically relevant traits, feeding behavior and Food Preference domestication determine production cost and profitability. Although there are intensive research efforts on feeding behavior and Food intake, little is known about Food Preference. Mandarin fish accept only live prey fish and refuse dead prey fish or artificial diets. Very little is currently known about the genes regulating this unique Food Preference. Using transcriptome sequencing and digital gene expression profiling, we identified 1,986 and 4,526 differentially expressed genes in feeders and nonfeeders of dead prey fish, respectively. Up-regulation of Crbp, Rgr and Rdh8, and down-regulation of Gc expression, consistent with greater visual ability in feeders, could promote positive phototaxis. Altered expressions of period, casein kinase and Rev-erbα might reset circadian phase. Down-regulation of orexigenic and up-regulation of anorexigenic genes in feeders were associated with lower appetite. The mRNA levels of Creb, c-fos, C/EBP, zif268, Bdnf and Syt were dramatically decreased in feeders, which might result in significant deficiency in memory retention of its natural Food Preference (live prey fish). There were roughly 100 times more potential SNPs in feeders than in nonfeeders. In summary, differential expression in the genes identified shed new light on why mandarin fish only feed on live prey fish, with pathways regulating retinal photosensitivity, circadian rhythm, appetite control, learning and memory involved. We also found dramatic difference in SNP abundance in feeders vs nonfeeders. These differences together might account for the different Food Preferences. Elucidating the genes regulating the unique Food Preference (live prey fish) in mandarin fish could lead to a better understanding of mechanisms controlling Food Preference in animals, including mammals.
