Abstract The neocortex is disproportionately expanded in human compared with mouse 1,2 , both its total volume relative to subcortical structures and the proportion occupied by supragranular layers composed of neurons that selectively make connections within other telencephalic structures. Single-cell transcriptomic analyses show an increased diversity glutamatergic neuron types pronounced gradients as a function cortical depth 3 . Here, probe functional anatomical correlates this diversity,...
Abstract Neurons are frequently classified into distinct groups or cell types on the basis of structural, physiological, genetic attributes. To better constrain definition neuronal types, we characterized transcriptomes and intrinsic physiological properties over 3,700 GABAergic mouse visual cortical neurons reconstructed local morphologies 350 those neurons. We found that most transcriptomic (t-types) occupy specific laminar positions within cortex, many t-types exhibit consistent...
The neocortex is disproportionately expanded in human compared to mouse, both its total volume relative subcortical structures and the proportion occupied by supragranular layers that selectively make connections within cortex other telencephalic structures. Single-cell transcriptomic analyses of mouse show an increased diversity glutamatergic neuron types pronounced gradients as a function cortical depth. To probe functional anatomical correlates this diversity, we describe robust Patch-seq...
Considerable progress has been made in understanding variations gene sequence and expression level associated with phenotype, yet how genetic diversity translates into complex phenotypic differences remains poorly understood. Here, we examine the relationship between background spatial patterns of across seven strains mice, providing most extensive cellular-resolution comparative analysis mammalian brain to date. Using comprehensive brainwide anatomic coverage (more than 200 regions),...
