2019, Journal of Neuroscience MethodsCitation Excerpt :Skilled reaching, the act of reaching to grasp an object as occurs in a reach-to-eat task, shares many similarities among both primates and rodents (Whishaw and Pellis, 1990; Whishaw, 1996). In rodents, skilled reaching to eat is a learned and composite movement in which the rat, inside a reaching box, uses olfactory cues, proprioception, whiskers, and tactile nose sense to locate food, and to define a reaching path for the paw to target the pellet (Whishaw and Tomie, 1989; Whishaw et al., 2017; Parmiani et al., 2018). Skilled reaching task starts with orienting, which consists of the rat’s approach to the front wall of the reaching box, and nose positioning over the pellet.
Directional Reaching for Water as a Cortex-Dependent Behavioral Framework for Mice
2018, Cell ReportsCitation Excerpt :To understand how mice detect and localize the spatial position of the water droplets, we performed a set of experiments during which different sensory modalities were removed or masked. For instance, rats orient the snout and actively sniff before initiating reach-to-grasp sequences in pellet reaching tasks (Whishaw and Tomie, 1989), while primates orient their gaze toward the target before initiating reaching movements (Biguer et al., 1982). In our experience, during the directional water reaching task, mice increased the rate of whisking and sniffing upon reward presentation, suggesting a role for whisker or olfactory systems.
