Topography of inputs into the hippocampal formation of a food-caching bird

The mammalian hippocampal formation (HF) is organized into domains associated with different functions. These differences are driven in part by the pattern of input along the hippocampal long axis, such as visual input to the septal hippocampus and amygdalar input to temporal hippocampus. HF is also organized along the transverse axis, with different patterns of neural activity in the hippocampus and the entorhinal cortex. In some birds, a similar organization has been observed along both of these axes. However, it is not known what role inputs play in this organization. We used retrograde tracing to map inputs into HF of a food-caching bird, the black-capped chickadee. We first compared two locations along the transverse axis: the hippocampus and the dorsolateral hippocampal area (DL), which is analogous to the entorhinal cortex. We found that pallial regions predominantly targeted DL, while some subcortical regions like the lateral hypothalamus (LHy) preferentially targeted the hippoc..., , , Data for 'Topography of inputs into the hippocampal formation of a food-caching bird', Applegate, M.C.; Gutnichenko, K.S.; Aronov, D.

The data is contained in a matlab data structure 'anatomy.m', which opens a matlab data structure anatomy. This structure has 4 fields to it:

Bird: an identifier for the birds used in the study.

pallialLabel: a boolean variable that is true if the bird ID had pallial regions annotated, false otherwise.

nonpallialLabel: a boolean variable that is true if the bird ID had nonpallial regions annotated, false otherwise.

data: a data structure with 8 fields. Each row contains information about a retrogradely labelled cell:
ROI: the 'region of interest (ROI)' for the cell. This field uses the same abbreviations for regions as the main paper. These are: HD (hyperpallium densocellulare),NFL (fronto-lateral nidopallium),NIL\_M (lateral intermediate nidopallium, medial portion),NIL\_L (lateral intermediate nidopallium, lateral portion),MS (medial septum),NDB (n...
