A primary sensory cortical interareal feedforward inhibitory circuit for tacto-visual integration.

Tactile sensation and vision are often both utilized for the exploration of objects that are within reach though it is not known whether or how these two distinct sensory systems combine such information. Here in mice, we used a combination of stereo photogrammetry for 3D reconstruction of the whisker array, brain-wide anatomical tracing and functional connectivity analysis to explore the possibility of tacto-visual convergence in sensory space and within the circuitry of the primary visual cortex (VISp). Strikingly, we find that stimulation of the contralateral whisker array suppresses visually evoked activity in a tacto-visual sub-region of VISp whose visual space representation closely overlaps with the whisker search space.

Helping Scholars Overcome Socioeconomic Barriers to Medical and Biomedical Careers: Creating a Pipeline Initiative.

To achieve their potential in medical and biomedical careers, students (scholars) from under-resourced backgrounds must build sophisticated skills and develop confidence and professionalism. To flourish in an advanced educational system that may be unfamiliar, these scholars also need networks of mentors and role models. These challenges can affect scholars at multiple stages of their education.

Objective evaluation of vertical Z-plasty with double transposition vermillion flaps for secondary whistling deformity correction: A method for uni- and bilateral correction.

Objectives: This study describes a modified method for secondary correction of whistling deformities in patients with unilateral and bilateral cleft lip/palate (CL/P), using a horizontal double transposition vermilion flap, including parts of the orbicularis oris muscle. The pre- and postoperative results were objectively evaluated.

Study Design: 34 patients with a whistling deformity who underwent secondary reconstruction between 07/2013 and 11/2018 were included in this study (mean age 20.

Visual deprivation independent shift of ocular dominance induced by cross-modal plasticity.

There is convincing evidence that the deprivation of one sense can lead to adaptive neuronal changes in spared primary sensory cortices. However, the repercussions of late-onset sensory deprivations on functionality of the remaining sensory cortices are poorly understood. Using repeated intrinsic signal imaging we investigated the effects of whisker or auditory deprivation (WD or AD, respectively) on responsiveness of the binocular primary visual cortex (V1) in fully adult mice.
