Building and integrating brain-wide maps of nervous system function in invertebrates
Curr Opin Neurobiol. 2024 Apr 2;86:102868. doi: 10.1016/j.conb.2024.102868. Online ahead of print.ABSTRACTThe selection and execution of context-appropriate behaviors is controlled by the integrated action of neural circuits throughout the brain. However, how activity is coordinated across brain regions, and how nervous system structure enables these functional interactions, remain open questions. Recent technical advances have made it feasible to build brain-wide maps of nervous system structure and function, such as brain activity maps, connectomes, and cell atlases. Here, we review recent progress in this area, focusing...

From innate to instructed: A new look at perceptual decision-making
Curr Opin Neurobiol. 2024 Apr 2;86:102871. doi: 10.1016/j.conb.2024.102871. Online ahead of print.ABSTRACTUnderstanding how subjects perceive sensory stimuli in their environment and use this information to guide appropriate actions is a major challenge in neuroscience. To study perceptual decision-making in animals, researchers use tasks that either probe spontaneous responses to stimuli (often described as "naturalistic") or train animals to associate stimuli with experimenter-defined responses. Spontaneous decisions rely on animals' pre-existing knowledge, while trained tasks offer greater versatility, albeit often at t...

An ethologically motivated neurobiology of primate visually-guided reach-to-grasp behavior
Curr Opin Neurobiol. 2024 Apr 1;86:102872. doi: 10.1016/j.conb.2024.102872. Online ahead of print.ABSTRACTThe precision of primate visually guided reaching likely evolved to meet the many challenges faced by living in arboreal environments, yet much of what we know about the underlying primate brain organization derives from a set of highly constrained experimental paradigms. Here we review the role of vision to guide natural reach-to-grasp movements in marmoset monkey prey capture to illustrate the breadth and diversity of these behaviors in ethological contexts, the fast predictive nature of these movements [1,2], and th...

The avian olfactory system and hippocampus: Complementary roles in the olfactory and visual guidance of homing pigeon navigation
Curr Opin Neurobiol. 2024 Mar 28;86:102870. doi: 10.1016/j.conb.2024.102870. Online ahead of print.ABSTRACTThe homing pigeon is the foundational model species used to investigate the neural control of avian navigation. The olfactory system is critically involved in implementing the so-called olfactory map, used to locate position relative to home from unfamiliar locations. The hippocampal formation supports a complementary navigational system based on familiar visual landmarks. Insight into the neural control of pigeon navigation has been revolutionised by GPS-tracking technology, which has been crucial for both detailing ...

Breaking the neural code of a cnidarian: Learning principles of neuroscience from the "vulgar" Hydra
Curr Opin Neurobiol. 2024 Mar 28;86:102869. doi: 10.1016/j.conb.2024.102869. Online ahead of print.ABSTRACTThe cnidarian Hydra vulgaris is a small polyp with a nervous system of few hundred neurons belonging to a dozen cell types, organized in two nerve nets without cephalization or ganglia. Using this simple neural "chassis", Hydra can maintain a stable repertoire of behaviors, even performing complex fixed-action patterns, such as somersaulting and feeding. The ability to image the activity of Hydra's entire neural and muscle tissue has revealed that Hydra's nerve nets are divided into coactive ensembles of neurons, asso...
