Modelling columnarity of pyramidal cells in the human cerebral cortex

Autor: Christoffersen, Andreas D., Møller, Jesper, Christensen, Heidi S.

For modelling the location of pyramidal cells in the human cerebral cortex we suggest a hierarchical point process in $\mathbb{R}^3$ that exhibits anisotropy in the form of cylinders extending along the $z$-axis. The model consists first of a general

Modelling spine locations on dendrite trees using inhomogeneous Cox point processes

Autor: Christensen, Heidi S., Møller, Jesper

Dendritic spines, which are small protrusions on the dendrites of a neuron, are of interest in neuroscience as they are related to cognitive processes such as learning and memory. We analyse the distribution of spine locations on six different dendri

Point processes on directed linear network

Autor: Rasmussen, Jakob G., Christensen, Heidi S.

In this paper we consider point processes specified on directed linear networks, i.e. linear networks with associated directions. We adapt the so-called conditional intensity function used for specifying point processes on the time line to the settin

Structured space-sphere point processes and $K$-functions

Autor: Møller, Jesper, Christensen, Heidi S., Cuevas-Pacheco, Francisco, Christoffersen, Andreas D.

This paper concerns space-sphere point processes, that is, point processes on the product space of $\mathbb R^d$ (the $d$-dimensional Euclidean space) and $\mathbb S^k$ (the $k$-dimen\-sional sphere). We consider specific classes of models for space-
