Multisensory processing

…have been developed to describe multisensory processing, including linear and nonlinear fusion. However, these algorithms typically treat each time step independently and fail to account for temporal dependencies in these signals. To address this limitation, we introduce a novel set of multisensory tasks that systematically incorporate controlled temporal

Multisensory processing in the brain is pivotal for forming perceptual decisions. While the primary sensory areas were traditionally considered strictly unisensory, recent rodent research has unveiled significant interactions between the auditory and visual cortices. Notably, V1 neurons were found to be hyperpolarized by auditory noise bursts or show sensitivity to the temporal coherence of audiovisual stimuli. These findings indicate that primary sensory regions possess the computational capacity for multisensory processing, although the impact of such cross-modal interactions on decision-mak

The striatum, the input nucleus of the basal ganglia, has primarily been implicated in the generation, initiation and selection of motor commands. In contrast to its anterior sub-area, the posterior part (pStr) or the “tail” of the striatum, is heavily innervated by auditory, visual and somatosensory regions suggesting its unique role in sensory-driven behaviors. Recent studies have shown a role for auditory pStr afferents in learned defensive behaviors. Despite these evidences, much remains unknown about striatal responses to various sensory modalities, their cellular specificity and how mult

…the hidden causal structure during multisensory processing are unknown. To address this, monkeys were trained to infer the probability of a potential common source from visual and proprioceptive signals on the basis of their spatial disparity in a virtual reality system. The proprioceptive drift reported by monkeys demonstrated that they combined historical information and current multisensory signals to e
