Meshes for Antennal Lobe (AL) glomeruli

Description

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.

Usage

hemibrain_al.surf

hemibrain_al_microns.surf

hemibrain_glomeruli_summary

odour_scenes

flywire_al.surf

Format

An object of class hxsurf of length 4.

An object of class hxsurf of length 4.

An object of class data.frame with 58 rows and 11 columns.

An object of class data.frame with 83 rows and 7 columns.

An object of class hxsurf of length 4.

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.

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).
