L2 Interneurons

A selection of all L2 interneurons that have more than 800 incoming excitatory synapses

Excitatory/Inhibitory Synapses (Volumetric)

Incoming inhibitory (red) or excitatory (green) synapses, rendered over transparent neurons.

Cortical Layers

Layers 1-6 and white matter

Reconstructed Whorl

A whorl whose axon can be traced all the way back to the source cell.

6-Class Subcompartments

Volumetric labels for soma, axon, dendrite, astrocyte, axon initial segment, and cilia

Axon Whorl

Unique whorled axon that makes multiple florets and synapses on soma and dendritic shafts of spiny neurons

Blood Vessels *

Vasculature within the tissue rendered in 3D

Chandelier Cell

A chandelier cell and some of the pyramidal neurons it inhibits

Compartmentalized Fibrous Object

Conjoint Whorls

Dendrite inside soma

A dendrite from one cell tunneling through the soma of another

Excitatory/Inhibitory Synapses (Point)

Incoming excitatory (yellow) and inhibitory (blue) synapses, rendered as point annotations

Fibrous Object

Unidentified object filled with fibrous substance.

Interacting Climbing Dendrites

"Parasitic" Glial Cells

Many glial cells appear "glued" to onto large pyramidal cells, with many appearing right next to somas. More examples can be found in Neuroglancer via the "c-shaped" tag.
