Augmented reality and artificial intelligence-assisted surgical navigation: Technique and cadaveric feasibility study.

Purpose: Augmented reality-based image overlay of virtual bony spine anatomy can be projected onto real spinal anatomy using computer tomography-generated DICOM images acquired intraoperatively. The aim of the study was to develop a technique and assess the accuracy and feasibility of lumbar vertebrae pedicle instrumentation using augmented reality-assisted surgical navigation.

Subjects And Methods: An augmented reality and artificial intelligence (ARAI)-assisted surgical navigation system was developed.

Face recognition under ambiguous visual stimulation: fMRI correlates of "encoding styles".

Object categorization during ambiguous sensory stimulation generally depends on the activity of extrastriate sensory areas as well as top-down information. Both reflect internal representations of prototypical object knowledge against which incoming sensory information is compared. However, besides these general mechanisms, individuals might differ in their readiness to impose internal representations onto incoming ambiguous information.
