“…Recent advances in cognitive neuroscience, demonstrating the importance of nasal respiration for human memory, must put to rest any thought that this is a niche topic. Hence, to understand cognition, we must face the challenge of understanding this complex and understudied sensory modality, in particular directional olfaction (Jacobs 2012(Jacobs , 2022. By embracing our olfactory minds, perhaps a whole new PROUSTian world will appear, crossing time, space and evolutionary history.…”

“…But this downplays or ignores a critical function of olfactory cognition, its role in spatial orientation, i.e., directional olfaction (Jacobs 2019 ). This is an important distinction because many paradoxes of olfactory anatomy and psychophysics can only be explained in terms of directional olfaction functions (Jacobs 2012 , 2022 ; Marin et al 2021 ). In the olfactory spatial hypothesis (Jacobs 2012 ), I discuss how unique patterns of allometry and neuroplasticity in the vertebrate olfactory system play a role in directional olfaction.…”

The extension of cognition beyond the brain to the body and beyond the body to the environment is an area of debate in philosophy and the cognitive sciences. Yet, these debates largely overlook olfaction, a sensory modality used by most animals. Here, I use the philosopher’s framework to explore the implications of embodiment for olfactory cognition. The philosopher’s 4E framework comprises embodied cognition, emerging from a nervous system characterized by its interactions with its body. The necessity of action for perception adds enacted cognition. Cognition is further embedded in the sensory inputs of the individual and is extended beyond the individual to information stored in its physical and social environments. Further, embodiment must fulfill the criterion of mutual manipulability, where an agent’s cognitive state is involved in continual, reciprocal influences with its environment. Cognition cannot be understood divorced from evolutionary history, however, and I propose adding evolved, as a fifth term to the 4E framework. We must, therefore, begin at the beginning, with chemosensation, a sensory modality that underlies purposive behavior, from bacteria to humans. The PROUST hypothesis (perceiving and reconstructing odor utility in space and time) describers how olfaction, this ancient scaffold and common denominator of animal cognition, fulfills the criteria of embodied cognition. Olfactory cognition, with its near universal taxonomic distribution as well as the near absence of conscious representation in humans, may offer us the best sensorimotor system for the study of embodiment.

“…The neural circuit examined in this paper was chosen because it spans specific functional aspects critical for social behavior. Together, the olfactory bulb, amygdala, and hippocampus form a tightly connected network (for review see Brodal, 1947 andEichenbaum andOtto, 1992) that provide information about autonomic, sensory, spatio-temporal, and affective context (Moberly et al, 2018;Jacobs, 2022) (see Figure 2). They are, thus, well situated to provide valuable information regarding the benefits and liabilities of the external environment during social interaction, exploration, and sampling of the sensory information.…”

Interactive neurorobotics: Behavioral and neural dynamics of agent interactions

et al. 2022

Interactive neurorobotics is a subfield which characterizes brain responses evoked during interaction with a robot, and their relationship with the behavioral responses. Gathering rich neural and behavioral data from humans or animals responding to agents can act as a scaffold for the design process of future social robots. This research seeks to study how organisms respond to artificial agents in contrast to biological or inanimate ones. This experiment uses the novel affordances of the robotic platforms to investigate complex dynamics during minimally structured interactions that would be difficult to capture with classical experimental setups. We then propose a general framework for such experiments that emphasizes naturalistic interactions combined with multimodal observations and complementary analysis pipelines that are necessary to render a holistic picture of the data for the purpose of informing robotic design principles. Finally, we demonstrate this approach with an exemplar rat–robot social interaction task which included simultaneous multi-agent tracking and neural recordings.

“…Other implications of the water to land transition are discussed by Lucia Jacobs, whose paper proposes how air-breathing set the stage for hippocampal evolution in terrestrial tetrapods [ 46 ]. Her olfactory navigation hypothesis [ 47 ] suggests that olfaction is not just about odour identification, but fundamentally about using odours for spatial navigation.…”

The nervous system is a product of evolution. That is, it was constructed through a long series of modifications, within the strong constraints of heredity, and continuously subjected to intense selection pressures. As a result, the organization and functions of the brain are shaped by its history. We believe that this fact, underappreciated in contemporary systems neuroscience, offers an invaluable aid for helping us resolve the brain's mysteries. Indeed, we think that the consideration of evolutionary history ought to take its place alongside other intellectual tools used to understand the brain, such as behavioural experiments, studies of anatomical structure and functional characterization based on recordings of neural activity. In this introduction, we argue for the importance of evolution by highlighting specific examples of ways that evolutionary theory can enhance neuroscience. The rest of the theme issue elaborates this point, emphasizing the conservative nature of neural evolution, the important consequences of specific transitions that occurred in our history, and the ways in which considerations of evolution can shed light on issues ranging from specific mechanisms to fundamental principles of brain organization. This article is part of the theme issue ‘Systems neuroscience through the lens of evolutionary theory’.
