Topic: whisker deflection

In nature, humans and animals are constantly bombarded with sensory information, which needs to be promptly contextualized to elicit the appropriate motor sequences through a process known as sensorimotor transformation. While we begin to understand how sensory information is transformed into motor action, it is still unclear in what way contextual information can modify a given sensorimotor plan. In this project, we investigate this phenomenon by training water restricted mice in a context-dependent multisensory detection task. We developed a behavioural paradigm in which mice are required to

Hierarchical processing has been shown to underlie complex functions such as invariant object coding. The perirhinal cortex (PER) is a higher-order region that sits at the apex of such processing streams and is involved in object recognition. Although it receives tactile information from barrel cortex (wS1) and secondary somatosensory cortex (S2), it is unclear how PER neurons respond to such stimuli. To address this, we performed population recordings of the barrel and perirhinal cortices of head-fixed mice while an object deflected their whiskers. Both ipsi- and contralateral stimulations we
