How scent, emotion, and memory are intertwined — and exploited
2020年2月27日 · Odors take a direct route to the limbic system, including the amygdala and the hippocampus, the regions related to emotion and memory. “The olfactory signals very quickly get to the limbic system,” Murthy said.

2023年5月1日 · The olfactory system serves multiple functions in humans. Through direct connection with the limbic system and cerebral cortex, smells intertwine with experiencing emotions and memories. Olfaction also serves a role in shaping behaviors and communication between animals. Odorants within the environment provide fundamental information for survival.

2023年8月14日 · From the olfactory bulbs, olfactory information reaches the primary olfactory cortex via the olfactory tract. The primary olfactory cortex interacts with a variety of cortical and limbic structures via sophisticated pathways that allow the smell to become integrated with memory, emotions, and taste. [1]

2022年9月19日 · From primary olfactory cortex, neuronal signals are sent to the higher cortical areas and the limbic system. The higher cortical area allows the conscious perception of odors and the limbic system governs analogous emotions, memory …
Memory and Plasticity in the Olfactory System: From Infancy to ...
This review of the neurobiology of emotional olfactory memory has focused on rat odor fear conditioning and highlights the fact that the olfactory modality might be particularly appropriate for understanding the interplay between limbic and cortical areas for the acquisition and storage of learned associations.
the olfactory nerves synapse on mitral cells whose axons project directly to the olfactory cortex. Olfactory Tract. The olfactory tract connects the olfactory bulb with the cerebral hemispheres.
Olfactory memory networks: from emotional learning to social …
Odors are powerful stimuli that can evoke emotional states, and support learning and memory. Decades of research have indicated that the neural basis for this strong “odor-emotional memory” connection is due to the uniqueness of the anatomy of the olfactory pathways.
The various parts of the limbic system are interconnected via numerous fiber tracts and pathways. Some of these pathways are shared with the olfactory system.
