Details

  • "bodyid" - unique identifier for a single hemibrain neuron.

  • "pre" - the number of presynapses (outputs) a neuron contains. Each of this is polyadic.

  • "post" - the number of postsynapses (inputs) to the neuron.

  • "upstream" - the number of incoming connections to a neuron.

  • "downstream" - the number of outgoing connections from a neuron.

  • "soma" - neuron size in voxels.

  • "sid" - which brain hemisphere contains the neuron's soma.

  • "voxels" - whether the neuron has a soma in the hemibrain volume.

  • "name" - the name of this neuron.

  • "connectivity.type" - the neuPrint designated 'type' for the neuron. A subset of neurons within a cell_type that share similar connectivity. A connectivity type is distinguished from a cell_type by an ending _letter, defined using CBLAST (Scheffer et al. 2020).

  • "cell_type" - neurons of a shared morphology that take the same cell body fibre tract and come from the same hemilineage (Bates 2019).

  • "cellBodyFiber" - The cell body fiber for a neuron, as read from neuPrint and annotated by a team under Kei Ito.

  • "putative.classic.transmitter" - putative neurotransmitter based on what neurons in the hemilineage in question has been shown to express, out of acetylcholine, GABA, glutamate.

  • "ito_lee_hemilineage" - the hemilineage that we reckon this cell_type belongs to, based on expert review of light level data from the K. Ito and T. Lee groups (Yu 2013, Ito 2013). See hemibrain_hemilineages.

  • "hartenstein_hemilineage" - the hemilineage that we reckon this cell_type belongs to, based on expert review of light level data from the V. Hartenstein Lee group (Wong 2013, Lovick 2013). See hemibrain_hemilineages.

  • "FAFB.match" - the ID of the manual match from the FAFB data set. ID indicates a neuron reconstructed in FAFBv14 CATMAID. Many of these neurons will be available through Virtual Fly Brain.

  • "FAFB.match.quality" - the matcher makers qualitative assessment of how good this match is: a poor match could be a neuron from a very similar same cell_type or a highly untraced neuron that may be the correct cell_type. An okay match should be a neuron that looks to be from the same morphological cell_type but there may be some discrepancies in its arbour. A good match is a neuron that corresponds well between FAFB and the hemibrain data.

  • "layer" - probabilistic mean path length from neuron from ALRNs, depends on connection strengths.

  • "layer.ct"- the mean layer for cell_type, rounded to the nearest whole number.

  • "axon_outputs"- number of outgoing connections from the neuron's predicted axon.

  • "dend_outputs"- number of outgoing connections from the neuron's predicted dendrite.

  • "axon_inputs"- number of incoming connections from the neuron's predicted axon.

  • "dend_inputs"- number of incoming connections from the neuron's predicted dendrite.

  • "total_length"- total cable_length of the neuron in micrometers.

  • "axon_length"- total axon cable_length of the neuron in micrometers.

  • "dend_length"- total dendrite cable_length of the neuron in micrometers.

  • "pd_length"- total cable_length of the primary dendrite 'linker' between axon and dendrite.

  • "segregation_index"- a quantification of how polarised a neuron is, in terms of its segregation of inputs onto its predicted dendrite and outputs onto its axon, where 0 is no-polarisation and 1 is totally polarised (Schneider-Mizell 2016).

  • "notes"- other notes from annotators.

  • "expected_cit"a citation that describes this glomerulus,

  • "expected_RN_female_1h".

  • "expected_RN_female_SD".

  • "missing".

  • "odour_scenes"the general 'odour scene(s)' which this glomerulus may help signal (Mansourian 2015, Bates 2020)

  • "key_ligand"the ligand that excites the cognate ALLRN or receptor the most, based on pooled data from multiple studies (Münch 2016)).

  • "valence"the presumed valence of this odour channel (Badel 2016).
