Subicular spatial codes arise from predictive mapping

William de Cothi, Laurenz Muessig, Fabio R. Rodrigues, Francesca Cacucci et autres

Abstract The successor representation has emerged as a powerful model for understanding mammalian navigation and memory; explaining the spatial coding properties of hippocampal place cells and entorhinal grid cells. However, the diverse spatial responses of subicular neurons, the primary output of the …

Exploring the sensitivity of episodic and spatial memory tests to healthy and pathological cognitive aging

Gina Michallat-Bragg, Megan S. Bennett, Bethany Iona Flewitt, Sayed Kazmi et autres

Introduction: In an increasingly aging society, testing hippocampal-dependent cognition in a quick and low resource manner will be crucial in: assessing the potential benefits of lifestyle choices and interventions affecting cognitive ageing (such as those involving exercise, diet, and sleep); detecting pathological …

Mice integrate conspecific and contextual information in forming social episodic-like memories under spontaneous recognition task conditions

T. W. Ross, Steven Poulter, Colin Lever, Alexander Easton

The ability to remember unique past events (episodic memory) may be an evolutionarily conserved function, with accumulating evidence of episodic-(like) memory processing in rodents. In humans, it likely contributes to successful complex social networking. Rodents, arguably the most used laboratory models, are …

Theta phase precession at encoding predicts subsequent memory of sensory-driven vector fields, & occurs in memory-dependent fields at retrieval

Steven Poulter, William de Cothi, Caswell Barry, Colin Lever

Abstract Theta phase precession is thought to confer key computational advantages (e.g. temporal compression suiting spike-timing related plasticity, cognitive relations as phase distances, and population-level coding for directions and sequences). However, direct evidence speaking to: 1) its widely-theorised role in enhancing memorability; …

Frequency matters: how changes in hippocampal theta frequency can influence temporal coding, anxiety-reduction, and memory

Miranda Hines, Steven Poulter, Vincent Douchamps, Francesca Pibiri et autres

Hippocampal theta frequency is a somewhat neglected topic relative to theta power, phase, coherence, and cross-frequency coupling. Accordingly, here we review and present new data on variation in hippocampal theta frequency, focusing on functional associations (temporal coding, anxiety reduction, learning, and memory). …

Neural correlates of distinct levels of predatory threat in dorsal periaqueductal grey neurons

Ricardo P. Bindi, Ricardo G. O. Maia, Francesca Pibiri, Marcus Vinícius C. Baldo et autres

The dorsal periaqueductal grey (PAG) is an important site for integrating predatory threats. However, it remains unclear whether predator-related activation in PAG primarily reflects threat itself and thus can distinguish between various degrees of threat, or rather reflects threat-oriented behaviours, with the …
