Cooperativity-dependent long-lasting potentiation in the crayfish lateral giant escape reaction circuit
MW Miller, SC Lee and FB Krasne
The ability of sensory neuron firing to cause the lateral giant escape
reaction increases following repeated sensory volleys at 4 Hz for 10 sec.
The increase occurs only when relatively large numbers of afferents are
repetitively stimulated, decays with a mean time constant of 21 hr, is
confined to the ganglia at which the repeated sensory volleys enter the
nerve cord, and is at least partially specific to those roots of a ganglion
that were tetanized. Transmission at the chemical synapses between
afferents and the largest of the first-order sensory neurons that link
afferents to the lateral giants displays a similar potentiation. This
phenomenon shares many properties with hippocampal long-term potentiation.
