Scales and Measurements in Neuroscience
Dr. David Kleinfeld
http://www-physics.ucsd.edu/neurophysics/
The goal is to establish basic neurophysiological principles
starting, as much as possible, from basic physical principles.
Biophysical scales of voltage, energy consumption, physical size,
etc., will be reviewed for all aspects of the nervous system. The
role of using chemical versus electrical processing will be
discussed as a means to insure spatial localization of dynamics.
The role of generic control for multistability in cell and
synaptic function will be discussed.
The role of thermal noise in setting detection limits in sensory
processing as well as in biophysical measurements will be
presented. We will also review classical measurement schemes, such
as voltage clamp, patch recording, extracellular unit recording,
the use of optical based contrast agents, and basic anatomical
techniques, including classical functional techniques.
