21. Dendritic spines receive most of the excitatory impulses ( EPSPs ) that enter a pyramidal cell . 22. Pyramidal cells in rats have been shown to undergo many rapid changes during early postnatal life.23. Entorhinal pyramidal cells of layer V receive strong input from the perirhinal cortex and sensory cortices. 24. In contrast, a single CA3 pyramidal cell receives input from about 50 different granule cells. 25. Meanwhile, the hippocampal pyramidal cells have been identified as the most vulnerable cells to ischemia. 26. K + channels in pyramidal cell dendrites provide a mechanism for controlling the amplitude of action potentials. 27. With proper connections, pyramidal cells take part in the circuitry responsible for vision guided motor function. 28. Two types of dendrites present on pyramidal cells are apical and soma ) opposite from the axon. 29. Mossy fibers form multiple synapses with the elaborate dendritic spines of CA3 pyramidal cells in stratum lucidum. 30. TASK-3 channels are also expressed in the hippocampus; both on pyramidal cells and interneurons.
