Developmental milestones and behavior of infant rats: The role of sensory input from whiskers

Publication date: Available online 6 August 2019Source: Behavioural Brain ResearchAuthor(s): Kirill Smirnov, Evgenia SitnikovaAbstractDevelopmental milestones are behavioral and physical skills which are considered as markers of neurodevelopment. In rodents, sensory input from whiskers plays a crucial role in development of brain functions. Development of whisker system in rats includes the early period of passive whisker touch (PN1-8) before the onset of coordinated whisker movements which underlie...

Different periods of forced abstinence after instrumental learning for food reward of different macronutrient value on responding for conditioned cues and AMPAr subunit levels

Publication date: Available online 5 August 2019Source: Behavioural Brain ResearchAuthor(s): Erin W. Noye Tuplin, Madi T. Wright, Matthew R. HolahanAbstractFood craving can be viewed as an intense desire for a specific food that propagates seeking and consuming behavior. Prolonged forced abstinence from rewarding foods can result in escalated food-seeking behavior as measured via elevated responding for food-paired cues in the absence of the primary reward. Palatable food consumption and food-seeking...

Distinct Dynamic Functional Connectivity Patterns of Pain and Touch Thresholds: A Resting-state fMRI Study

Publication date: Available online 5 August 2019Source: Behavioural Brain ResearchAuthor(s): Yueming Yuan, Li Zhang, Linling Li, Gan Huang, Ahmed Anter, Zhen Liang, Zhiguo ZhangAbstractDynamic functional connectivity (dFC) analysis based on resting-state functional magnetic resonance imaging (fMRI) has gained popularity in recent years. Despite many studies have linked dFC patterns to various mental diseases and cognitive functions, little research has used dFC in the investigation of low-level sensory...
