CA3 Lucidum LAX
* indicates new v2.0 neuron type
Name Supertype (ID:Family:Type:Subregion)
CA3 (i)02310 Lucidum LAX S141602:Mossy Fiber-related:L-targeting:CA3

Name derivation
This name uses the common core of the name in the cited literature. The modifier describes the "Lucidum AXons" that distinguish this from the other lucidum cell types.

"Fig. 4. Single stratum lucidum interneurons {CA3 Lucidum LAX} [in CA3] express both calcium-permeable and calcium-impermeable AMPA [alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid] receptors. . . . (c) Camera-lucida drawings of typical stratum lucidum interneurons used for electrophysiological recordings. The dendritic trees of the recorded neurons were oriented either vertically (cell 3) or horizontally (cell 5) with respect to the pyramidal-cell layer. In a number of cells, the dendritic tree possessed both vertical and horizontally oriented dendritic branches (cells 1, 2 and 4), which we have termed intermediate. In most cells, the axonal arbor occupied the [CA3] stratum lucidum and/or to a lesser extent the stratum pyramidale. PhTx [philanthotoxin-433]-sensitive AMPA receptors were found on all morphological classes of stratum lucidum interneuron. The incidence of PhTx-sensitive mossy inputs was highest among cells with vertically oriented dendrites that had dendritic spines (for example, cell 3)."

Merger with CA3 MFA 02332 Borderline D: SP, SO? This cell is based on one very blurry figure, but a dendrite in two of the cells does slightly enter SO.
