“…In this strategy, relationships among landmarks, as well as the subject's stationary location, assist in defining one's location within the environment. Importantly, these two strategies are in continual dialogue: allocentric representations of one's self-location are updated by egocentrically derived changes of one's self-location, and vice-versa, one's egocentric perception is changed according to the allocentric cognitive map, maintaining one's ongoing relations with the environment [11,33,34].…”

The concepts of agency of one's actions and ownership of one's experience have proven useful in relating body-representations to bodily-consciousness. Here we apply these concepts to cognitive maps. Agency is defined as "the sense that I am the one who is generating the experience represented on a cognitive map", while ownership is defined as "the sense that I am the one who is undergoing an experience, represented on a cognitive map". The roles of agency and ownership are examined with respect to the transformation between egocentric and allocentric representations, the underlying neurocognitive and computational mechanisms, and within the neuropsychiatric domain including Alzheimer's disease and other memory-related disorders, in which the senses of agency and ownership may be disrupted.

“…We elaborate on 559 this hypothesis below. 560 561 In gymnotiform fish, PG cells respond to object motion (electrosensory and visual; 562 Wallach et al, 2018). Anatomical studies indicate that these responses are driven by tectal input 563 (Giassi et al, 2011).…”

“…The gymnotiform tectum maintains a topographic representation of 564 electrosensory input and tracks continuous object motion (Bastian, 1982). PG neurons generate a 565 major transformation of their tectal input -the majority of PG motion sensitive cells lose 566 topographic information and respond over the fish's entire body but only to object motion start 567 (all cells) and stop (some cells) and not the intervening continuous motion (Wallach et al, 2018). that, once activated, was capable of sustained discharge.…”

“…In functional terms, we propose that the propagation of neural activity in 624 the DL network represents the fish's estimate of where it is located along the trajectory between 625 a landmark and food. When the fish reaches the food (or another landmark), PG neurons would 626 again discharge to signal the total time/distance travelled (Wallach et al, 2018) and the potential 627 start of a new trajectory. In this model, learning a trajectory from a particular landmark to food 628 would consist of strengthening the synaptic connections of the 'moving bump' induced by that 629 landmark so as to represent the time/location sequence leading from the landmark to food.…”

15In mammals, the localization of distinct landmarks is performed by hippocampal neurons 16 that sparsely encode an animal's location relative to surrounding objects. Similarly, the dorsal 17 lateral pallium (DL) is essential for spatial learning in teleost fish. The DL of weakly electric 18 gymnotiform fish receives sensory inputs from the preglomerular nucleus (PG), which has been 19 hypothesized to encode the temporal sequence of electrosensory or visual landmark/food 20 encounters. Here, we show that DL neurons have a hyperpolarized resting membrane potential 21 combined with a high and dynamic spike threshold that increases following each spike. Current-22 evoked spikes in DL cells are followed by a strong small-conductance calcium-activated 23 potassium channel (SK) mediated after-hyperpolarizing potential (AHP). Together, these 24 properties prevent high frequency and continuous spiking. The resulting sparseness of discharge 25 and dynamic threshold suggest that DL neurons meet theoretical requirements for generating 26 spatial memory engrams by decoding the landmark/

“…This is because there are many uses of a cognitive map that are independent of planning, such as present location on a map 39 and corrections to a dead reckoning system 40 , with none of the prospective counterfactual aspects of checking multiple sequences of choices before enacting one as suggested by studies of planning in rodents 40,41 . Consistent with this hypothesis, it has been found that a likely homolog of the mammalian hippocampus in fish, the dorsolateral pallium, is hypertrophied in squirrelfish, a nocturnal reef fish 42 , and evidence for how the pallium generates a cognitive map has been found in another animal that inhabits complex habitats with short sensing range, the electric fish 43 .…”

The shift from life in water to life on land advantaged planning in visually-guided behavior

4Other than formerly land-based mammals such as whales and dolphins that 5 have returned to an aquatic existence, it is uncontroversial that land animals 6 have developed more elaborated cognitive abilities than aquatic animals. Yet 7 there is no apparent a-priori reason for this to be the case. A key cognitive 8 faculty is the ability to plan. Here we provide evidence that in a dynamic 9 visually-guided behavior of crucial evolutionary importance, prey evading a 10 predator, planning provides a significant advantage over habit-based action 11 selection, but only on land. This advantage is dependent on the massive in-12 crease in visual range and spatial complexity that greeted the first vertebrates 13 to view the world above the waterline 380 million years ago. Our results have 14 implications for understanding the evolutionary basis of the limited ability of 15 animals, including humans, to think ahead to meet slowly looming and distant 16 threats, toward a neuroscience of sustainability. 17 Introduction 18The emergence of vertebrates on to land over 350 million years ago was preceded by a massive 19 increase in visual range when their eyes moved to the top of the head to look over the water 20 surface and tripled in size (1). The optical difference between inland waters-where transitional 21 tetrapods are thought to have emerged-and air resulted in more than a 100-fold increase in 22 visual range, from about a body length to hundreds of body lengths ahead (1, 2). Within the 23 greatly enhanced range of Devonian aerial vision was rich structure provided by vegetation 24 (3) and other terrestrial features, providing complex visual scenes to animals (Supplementary 25 Fig. 1A-B). In this study we will test the hypothesis that for visually guided behaviors, the 26 2 increase in visual range and observed environmental complexity that accompanied the onset of 27 terrestriality advantaged the evolution of neural circuitry for deliberation over multiple futures 28 (4, 5). 29This study builds on investigations into the neural basis of action selection that suggest the ex-30 istence of two competing, distinct, and largely parallel decision making systems: habit-based 31 action selection, and plan-based action selection (6, 7). These two control paradigms have 32 primarily been associated with the lateral striatum and its dopaminergic afferents (8-10) for 33 habit, and the interaction between hippocampus and the prefrontal cortex (nidopallium cau-34 dolaterale in birds (11)) (12-19) for planning. The similarity between lamprey (jawless fish 35 that preceeded mammals by 560 million years) and mammalian basal ganglia in the direct and 36 indirect pathways of the dopamine expressing striatal projection neurons (20-22) suggests that 37 this structure-and thus the habit-based action selection system it supports-evolved very early 38 on in vertebrate evolution. 39 In mammals, planning has been related to the phenomenon of nonlocal spatial representations 40 in hippocampal activity. Two quintessential examples of this phen...
