Organisms process sensory information in the context of their own moving bodies, an idea referred to as embodiment. This is important for developmental neuroscience, robotics and systems neuroscience. The mechanisms supporting embodiment are unknown, but a manifestation could be observation mice brain-wide neuromodulation, including primary visual cortex, driven by task-irrelevant spontaneous body movements. We tested this hypothesis macaque monkeys (Macaca mulatta), primate model human...
Abstract Feedback in the brain is thought to convey contextual information that underlies our flexibility perform different tasks. Empirical and computational work on visual system suggests this achieved by targeting task-relevant neuronal subpopulations. We combine two tasks, each resulting selective modulation feedback, test whether feedback reflected combination of both selectivities. used feature-discrimination specified at one possible locations uncoupled decision formation from motor...
Abstract Organisms process sensory information in the context of their own moving bodies, an idea referred to as embodiment. This is important for developmental neuroscience, and increasingly plays a role robotics systems neuroscience. The mechanisms that support such embodiment are unknown, but manifestation could be observation mice brain-wide neuromodulation, including primary visual cortex, driven by task-irrelevant spontaneous body movements.

When processing information from multiple sensory sources, inputs seem to be weighted according the reliability of their estimate (Driver & Spence, 2000; Ernst Bülthoff, 2003). This differential weighting typically leads a dominance one sense over another for given percept. For example, in temporal perception, auditory system dominates visual (Repp Pennel, 2002; Romei, De Haas, Mok, Driver, 2011), whereas spatial (Bertelson Aschersleben, 1998). However, decisions are not independent...
Perceptual decisions have long been framed in terms of the actions used to report a choice. Accordingly, studies perceptual decision-making historically relied on tasks with fixed choice-response mappings, which choice and motor response are inextricably linked. Although several since dissociated response, they typically involved dynamic switching mapping trial-by-trial basis. Thus, it remains unclear if abstract representations arise specifically when relationships change dynamically, or...
Information about where our hands are arises from different sensory modalities; chiefly proprioception and vision. These inputs differ in variability situation to (or task task). According the idea of ‘optimal integration’, information provided by sources is combined proportion their relative reliabilities, thus maximizing reliability estimate. It uncertain whether optimal multisensory integration contributions limb position requires executive resources. If so, then it should be possible...
During perceptual decisions the activity of task-relevant sensory neurons is typically correlated with an animal's decision. Such decision-related activity, often quantified as "choice-probability", thought to reflect feed-forward and feedback sources (Nienborg & Cumming, 2009). For a feature-discrimination task, this implies that feature-selective. A recent computational account choice-probabilities (Haefner et al., 2016) hypothesizes modulation by feature-selective attention source same...
Previous work in mice reported neuronal modulations visual cortex by movements. Beyond the sizeable effects of locomotion, such were associated with task-unrelated spontaneous body movements, challenging view that activity neurons early sensory cortices is driven predominantly input a single modality. These not limited to stimulus-evoked responses but also observed for activity, suggesting population spans multiple dimensions defined ongoing behavioral states. To examine possibility...
