In the current release of the Allen Cell Types Database, we include electrophysiological recordings from 1058 mouse cells and 279 human cells, a subset of which also include morphological reconstruction and Neuronal Models. The Cell Feature Search page allows you to find cells whose associated properties satisfy certain conditions. For example, you can choose to select only cells from a certain species and a certain cortical layer. You can also use this page to find cells for which a specific type types of data is are available. For example, you can choose to select only cells for which there are is not only electrophysiological data, but also models for that data and also morphological reconstructions and neuronal models. 

You can set conditions on discrete properties by menu selections at the top of the page.
