Numbers of granule cells and GABAergic boutons remain correlated in shrunken sclerotic hippocampi of sea lions with temporal lobe epilepsy

The data set describes inhibitory cells and synaptic boutons in control and epileptic sea lions. It is a table of subjects with sex, age, hippocampus (sclerotic or not), group (control, unilateral sclerotic, or bilateral sclerotic) and data from each individual. Data include numbers of GABAergic boutons in layers of the dentate gyrus, numbers of granule cells, and numbers of GABAergic cell body profiles. Stereological methods were used so data on counts and coefficients of error are included. Another data set is similar but for rats in which only boutons were counted., , # Numbers of granule cells and GABAergic boutons remain correlated in shrunken sclerotic hippocampi of sea lions with temporal lobe epilepsy

## Description of the data and file structure

Data are anatomical values from stereological analysis of the hippocampal dentate gyrus of California sea lions with and without temporal lobe epilepsy.

**Description:** 

##### Variables

* sea lion sex, side (left or right), hippocampus (sclerotic or normal), group (control, unilateral sclerotic, or bilateral sclerotic)
* number of GABAergic boutons (by layer of the dentate gyrus), stereological parameters of bouton counts (number counted, coefficients of error), number of GABAergic cell profiles (by layer of the dentate gyrus), number of GABAergic cells estimated by stereology per dentate gyrus, volume of the dentate gyrus
..., , **Changes after May 13, 2025:** GAD cell counts were updated. Old version was extrapolated from profile counts. New version based on more direct and accurate stereological counts.

**Changes after Jan 6, 2026:** Dentate gyrus volume data was added.
