Topic 4B Module 1: Somatic senses: discriminative touch and proprioception
Title
1 Module Overview
2 Module Objectives
3 Introduction to the somatosensory system
4 Fine touch from skin receptors (cutaneous dicriminative mechanoreceptors)
1. 4.1 The four common fine touch receptors
2. 4.2 Transduction in receptors for fine touch involves stretch
5 Differentiating information from different cutaneous mechanoreceptors
1. 5.1 Adaptation rate differentiates cutaneous mechanoreceptors
2. 5.2 Receptive field size differentiates cutaneous mechanoreceptors
  1. 5.2.1 RF is the determining factor in coding object features
  2. 5.2.2 Variation in spatial resolution across the body correlates with density of neurons with small RFs
6 Linking the physiology to our perceptions
7 Summary of the physiology
1. 7.1 Material for revision
2. 7.2 FYI: We move our fingers in different ways to gain different types of information
8 Proprioception: The sense of position, force, muscle stretch and muscle tension
9 Test your knowledge
