Rev. Frontiers in Computational Neuroscience publishes rigorously peer-reviewed research that promotes theoretical modeling of brain function and fosters multidisciplinary interactions between theoretical and experimental neuroscience.

Science 589, 584–589. “Dendritic cortical microcircuits approximate the backpropagation algorithm,” in: Advances in Neural Information Processing Systems 31. The location by which place/grid cells form their firing fields are modulated by self-motion stimuli or path integration (McNaughton et al., 2006), and are also modulated by landmarks such as local or distant environmental cues or its overall shape (O'Keefe and Burgess, 1996; Yoder et al., 2011; Krupic et al., 2015). One of the main criticisms is the lack of generalization and the amount of training examples that DL algorithms require for learning to solve even simple and structured tasks. 22, 772–789. This informed development of AI systems will in turn provide opportunities to validate the result against rodent experiments and therefore, to generate hypothesis that can inform neuroscience. Despite these contributions that have propelled the recent impressive progress and applications of DL and RL, there are important limitations in these areas which can benefit from the knowledge generated in neuroscience. Nat. This is due to the difficulty of experimental preparations and lack of tools to analyze such complex data. Parietal cortex (PC) and anterior thalamic nucleus (ATN) are anatomically and functionally well-positioned to interface between egocentric and allocentric frames of reference within a larger navigational network.

For example (Stoianov et al., 2018), demonstrated how a RL model can replicate results in rodent experiments in which contextual cues are manipulated to explore the behavioral and brain constrains in goal directed navigation tasks. Front. Inception loops discover what excites neurons most using deep predictive models. A., Fischer, I., Dillon, J. V., and Murphy, K. (2019). Descriptive models of spatial navigation have the goal of characterizing what the system does, usually reproducing experimental data (Sutherland and Hamilton, 2004). Neurosci. These place responses have been described as landmark or object vector cell activity (McNaughton et al., 1995; Deshmukh and Knierim, 2013; Wilber et al., 2014; Høydal et al., 2019). Learning to predict consequences as a method of knowledge transfer in reinforcement learning. In this section we outline how considering spatial navigation as the intersection point between neuroscience and AI research can provide a valuable opportunity to advance both fields and we review the limitations of the approaches presented in this paper. In addition, we have summarized the neurobiology of RL and how RL has been implemented to solve spatial navigation tasks. Swanson, L. W. (2003). Biol. doi: 10.1038/nn.3311, Botvinick, M., Ritter, S., Wang, J. X., Kurth-Nelson, Z., Blundell, C., and Hassabis, D. (2019). In one theory about memory, hippocampal replay plays a crucial role in forming an index or memory trace that binds together experience components in the neocortex for long-term storage and knowledge extraction during sleep (Frankland and Bontempi, 2005). Man Cybern. There is also evidence that not only previous experiences but also unexplored possibilities are used to evaluate possible outcomes in navigation tasks in rodents (Dragoi and Tonegawa, 2011). “Reinforcement learning and hippocampal dynamics,” in Analysis and Modeling of Coordinated Multi-neuronal Activity, ed M. Tatsuno (New York, NY: Springer), 299–312. Trends Neurosci. 39, 1–38. Depending on what the goal of the model is, it can be classified as descriptive, mechanistic, or normative (Dayan and Abbott, 2001). doi: 10.1016/j.conb.2019.09.011, Navratilova, Z., Giocomo, L.

In contrast, when the hippocampus is involved, faster one-shot associative learning rules are applied to solve spatial navigation. Besides using ANNs and RL to solve spatial navigation tasks, important concepts, and mechanisms found in neuroscience experiments have been used to improve algorithms in AI. doi: 10.3758/s13414-019-01760-1, Clark, B.

Percep. (2002). Curr. (2017). Sci. Available online at: Computational descriptive models propose that cell populations within the anterior thalamic nuclei, parietal cortex, and retrosplenial cortex operate as a network that transforms spatial information from an egocentric (e.g., body centered) to allocentric (i.e., map-like) frame of reference and vice versa (reviewed in Clark et al., 2018). For example, with more studies about grid cells, models that aim to understand how place cells and grid cells interact have been very important to understand the restrictions in the circuitry between the enthorinal cortex and the hippocampus (Solstad et al., 2006). Recent work has established that a circuit including the parietal and retrosplenial cortex and neighboring hippocampal and subcortical regions play a central role in processing an egocentric coordinate system (Clark et al., 2018; Wang et al., 2018, 2020; Hinman et al., 2019; LaChance et al., 2019). Neurosci. Neuronal representation of environmental boundaries in egocentric coordinates. Neural Circ. Dropout: a simple way to prevent neural networks from overfitting. (2019). From this perspective, hippocampal activity encodes the animal's future locations which are restricted by the environment and their value (rewards) (Stachenfeld et al., 2017; Brunec and Momennejad, 2019).

Here we reviewed the neuroscience and modeling work of spatial navigation. In contrast, the analogous biological networks show a great deal of generalization during learning. Figure 1. This criticism raises the possibility that even if we can train ANNs that perform spatial navigation, this is not a guarantee that the brain might solve the task in a similar way (Burak and Fiete, 2009; Kanitscheider and Fiete, 2017).

Even though one of the most popular algorithms in autonomous vehicles has a version based on certain aspects of the neuroscience of the navigation system in rodents (Milford et al., 2010; Ball et al., 2013; Xu L. et al., 2019), this particular approach has not been designed to advance what we know about the brain, suggesting a potentially unrealized opportunity for synnergy between the neuroscience of spatial navigation and AI (Dudek and Jenkin, 2002; Zafar and Mohanta, 2018).

Opin. doi: 10.1016/j.neuron.2011.12.028. Similar to location specific firing in the hippocampus and parahippocampal cortex (place, grid, border, and object vector cells), the preferred direction of HD cells can be controlled by self-motion cues (angular path integration) and environmental cues (reviewed in Taube, 2007). In particular, end-to-end approaches to solve navigation tasks can help in the advancement of the neuroscience of spatial navigation because the potential solutions are not restricted to the current knowledge of the experimenter. doi: 10.1016/j.tins.2011.08.001, Peyrache, A., Duszkiewicz, A.

For example, the manipulation of spatial representations is difficult to study with current approaches in neuroscience (Kanitscheider and Fiete, 2017). For example, DNNs have been used to reproduce brain activity in the visual system to learn about the organization of this network in primates (Walker et al., 2019) and mice (Cadena et al., 2019). Using neuroscience to develop artificial intelligence. Besides these models of head orientation, there is an extensive body of modeling work to understand how place is represented in the brain.

Adapted from Solstad et al. Journal Impact. doi: 10.1038/nn1053. In this type of navigation, loops between the cortex and the basal ganglia are proposed to support stimulus-response associations and procedural memory, which are linked to route or cue-based navigation. PLoS Comput. 60, 136–144. We therefore invite original contributions on a wide range of topics that present the fruits of such cooperation, or provide stimuli for future alliances.
