Arena size modulates functional responses via behavioral mechanisms

Group Behavior: Social Context Modulates Behavioral Responses to Sensory Stimuli

A new study reveals an unanticipated role for social context in driving group behavior of a solitary species to a sensory stimulus and is mediated by mechanosensory neurons signaling touch interactions among individuals.

TRPV1-expressing primary afferents generate behavioral responses to pruritogens via multiple mechanisms.

The mechanisms that generate itch are poorly understood at both the molecular and cellular levels despite its clinical importance. To explore the peripheral neuronal mechanisms underlying itch, we assessed the behavioral responses (scratching) produced by s.c. injection of various pruritogens in PLCbeta3- or TRPV1-deficient mice. We provide evidence that at least 3 different molecular pathways ...

Open-field behavior withstands drastic changes in arena size.

Individual voles were tested on successive days under increasing, decreasing, or randomly changing arena size. Locomotor behavior was adjusted to arena size by (i) preserving the same level of activity, (ii) taking longer but less frequent trips in smaller arenas in contrast to taking more frequent yet shorter trips in the larger arenas, and (iii) moving in the entire space available for explor...
