The membrane potential of astrocytes is very close to EK and the cells tend not to depolarize enough to open the channels. C. Astrocytes are strongly coupled by gap junctions, so depolarization in one cell would be opposed by negative current flow from neighboring cells. Describe the ventricular system, the pattern of flow of CSF and the dynamics of CSF absorption and production. Introduction to Sensory Systems 1. Be able to define these attributes and to give specific examples for different sensory systems.
Adaptation is a common property of many sensory receptors.
Steven's Law describes the psychophysical relationship between stimulus intensity and perceived intensity. Be able to define agranular cortex and to give two examples. Compare and contrast the characteristics of the two major classes of nociceptors described in class. Name at least 3 ways in which they differ and 3 ways in which they are similar. Name 3 types of receptors that have unmyelinated axons.
