Topic: detection thresholds

Integration of information across different senses is a common property of cortical neurons. Somatosensory input impacts on auditory cortical processing through a mechanism that suppresses sound-evoked activity (Lohse et al., 2021). We carried out a number of experiments to investigate a) the perceptual implications of this crossmodal integrative process and b) its context dependence. In order to assess whether somatosensory suppression of sound-evoked activity affected the ability of mice to detect acoustic stimuli, we first performed a near-threshold sound detection experiment. While simulta
