Summary from last week
Action potential can be explained by time- and
voltage-dependent changes in conductance
properties of the axonal membrane.
Voltage-clamp was an important technique that

Summary from Previous
The electrical signals neurons generate
result from alterations in the membrane
These alterations are accomplished by
varying the permeability of the
membrane to sodium and potassium.
Pain receptors are called nociceptors.
Nociceptors are usually free nerve
Nociception constitutes an anatomically
distinct modality from discriminative
touch and thermoception.
Nerve cell bodies reside in DRG
