Scaling of ventral hippocampal activity during anxiety Carlo Cerquetella, Camille Gontier, Thomas Forro, Jean-Pascal Pfister, Stéphane Ciocchi Journal of Neuroscience 27 January 2025, e1128242025; DOI: 10.1523/JNEUROSCI.1128-24.2025
Abstract Acquiring and exploiting memories of rewarding experiences is critical for survival. The spatial environment in which a rewarding stimulus is encountered regulates memory retrieval. The ventral hippocampus (vH) has been implicated in contextual memories involving rewarding stimuli such as food, social cues or drugs. Yet, the neuronal representations and circuits underlying contextual memories of socially rewarding stimuli are poorly understood.
Abstract Background The hippocampus supports a multiplicity of functions, with the dorsal region contributing to memory-related spatial representations, while the ventral hippocampus (vH) is primarily involved in emotional processing. While spatial encoding has been extensively investigated, how the vH activity is tuned to emotional states, e.g. to different anxiety levels, is not well understood.
