System introduction

Sensory system

The sensory system is a part of the nervous system responsible for processing sensory information from the environment and the body. It includes specialized sensory receptors for vision, hearing, taste, smell, touch, pain, temperature, and proprioception. These receptors convert stimuli into neural signals, which are transmitted to specific brain regions for interpretation. This system allows organisms to perceive, interpret, and interact effectively with their surroundings, ensuring survival and conscious experience.

Equal-weight species-calibrated score

mean(clip(matrix_value / species_positive_q99, 0, 1))

  • Each mapped gene is scaled by its 99th percentile among positive cells in the complete source-species H5AD.
  • The same 15 mapped genes and SP121 species calibration are used for every system.
  • The score is descriptive relative expression on a 0–1 scale.
