Odor supported place cell model and goal navigation in rodents (Kulvicius et al. 2008)

Accession: 118434

" ... Here we model odor supported place cells by using a simple feed-forward network and analyze the impact of olfactory cues on place cell formation and spatial navigation. The obtained place cells are used to solve a goal navigation task by a novel mechanism based on self-marking by odor patches combined with a Q-learning algorithm. We also analyze the impact of place cell remapping on goal directed behavior when switching between two environments. ..."

navPFdevelv03.m - place field model implemented by using feed-forward
                   network with winner takes all learning
                   algorithm.  Place cells are formed from visual
                   and olfactory input.

createCellsAll.m - creates place fields. This script is called by
                   "navPFdevelv03.m".

plotPFM.m - plots place field maps. This function is called by
                   "navPFdevelv03.m".

navPFQLv14.m - goal navigation based on palce cells and Q-learning
                   with function aproximation.

navUrineBasedv04.m - goal navigation based on self generated odor
                   marks (no place fields).

navPFQLUv07.m - goal navigation using combined navigation algorithm
                   (Q-learning based on place cells + self-marking
                   navigation)
