Meshes for Antennal Lobe (AL) glomeruli

Source: R/hemibrain_data.R

3D meshes of 51 olfactory + 7 thermosensory antennal lobe glomeruli for the the hemibrain volume. They are represented as a hxsurf object, in which 'regions' are defined, one for each glomerulus. Meshes are available both in raw voxels and in microns. You can see which glomeruli are truncated, and by roughly how much by examining. The glomeruli are made from PN dendrites. hemibrain_glomeruli_summary.

Value

hemibrain_glomeruli_summary is a data.frame with the columns:

  • "expected_cit"the citation for the number of expected RNs,

  • "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).

Details

note that hemibrain coordinate system has the anterior-posterior axis aligned with the Y axis (rather than the Z axis, which is more commonly observed).

These meshes were generated by Sri Jagannathan and Tomke Stuerner based on the location of PN dendritic synapses.
