nervous system
• following a brief bursts of presynaptic stimulation, the charge transfer in CA3 neurons is reduced compared with wild-type cells
• following a burst of presynaptic stimulation with or without pharmacologically isolating kainate receptor excitatory postsynaptic potentiation, CA3 pyramidal cells exhibit a decreased probability of spike after the fifth pulse compared with wild-type cells
• mice exhibit an increase in latency of spikes to the stimulation pulse (jitter) compared with wild-type mice
• however, mice exhibit normal paired-pulse facilitation and long term potentiation
|
• mice exhibit reduced kainate-evoked inward currents in the CA3 pyramidal cells and CA1 interneurons compared with wild-type mice
• however, Purkinje cells exhibit normal kainate-evoked inward currents
|
• kainate receptor excitatory postsynaptic current decay kinetics and rise time are faster than in wild-type mice
