Hypothetical Roles of the Olfactory Tubercle in Odor-Guided Eating Behavior [PDF]

Frontiers in Neural Circuits, 2020
Olfaction plays an important role in the evaluation, motivation, and palatability of food. The chemical identity of odorants is coded by a spatial combination of activated glomeruli in the olfactory bulb, which is referred to as the odor map.

Learning-dependent structural plasticity of intracortical and sensory connections to functional domains of the olfactory tubercle [PDF]

Frontiers in Neuroscience, 2023
The olfactory tubercle (OT), which is a component of the olfactory cortex and ventral striatum, has functional domains that play a role in odor-guided motivated behaviors.

Connectivity of the olfactory tubercle: inputs, outputs, and their plasticity [PDF]

Frontiers in Neural Circuits
The olfactory tubercle (OT) is a unique part of the olfactory cortex of the mammal brain in that it is also a component of the ventral striatum. It is crucially involved in motivational behaviors, particularly in adaptive olfactory learning.

Endogenous opioids in the olfactory tubercle and their roles in olfaction and quality of life [PDF]

Frontiers in Neural Circuits
Olfactory dysfunctions decrease daily quality of life (QOL) in part by reducing the pleasure of eating. Olfaction plays an essential role in flavor sensation and palatability.

Interhemispheric asymmetry of c‐Fos expression in glomeruli and the olfactory tubercle following repeated odor stimulation [PDF]

FEBS Open Bio, 2020
Odor adaptation allows the olfactory system to regulate sensitivity to different stimulus intensities, which is essential for preventing saturation of the cell‐transducing machinery and maintaining high sensitivity to persistent and repetitive odor ...

Cellular Profiles of Prodynorphin and Preproenkephalin mRNA-Expressing Neurons in the Anterior Olfactory Tubercle of Mice [PDF]

Frontiers in Neural Circuits, 2022
The olfactory tubercle (OT) is a striatal region that receives olfactory inputs. mRNAs of prodynorphin (Pdyn) and preproenkephalin (Penk), precursors of dynorphins and enkephalins, respectively, are strongly expressed in the striatum. Both produce opioid

Distinct representation of cue-outcome association by D1 and D2 neurons in the ventral striatum’s olfactory tubercle [PDF]

eLife, 2022
Positive and negative associations acquired through olfactory experience are thought to be especially strong and long-lasting. The conserved direct olfactory sensory input to the ventral striatal olfactory tubercle (OT) and its convergence with dense ...

Synaptic plasticity and roles of orexin in distinct domains of the olfactory tubercle [PDF]

Frontiers in Neural Circuits
Olfactory behavior is highly plastic, and the olfactory tubercle (OT), a component of the olfactory cortex and ventral striatum, includes anteromedial (amOT) and lateral (lOT) domains with roles in attractive and aversive olfactory behavioral learning ...

Function of orexin-1 receptor signaling in the olfactory tubercle in odor-guided attraction and aversion [PDF]

Communications Biology
While olfactory behaviors are influenced by neuromodulatory signals, the underlying mechanism remains unknown. The olfactory tubercle (OT), a component of the olfactory cortex and ventral striatum, consists of anteromedial (am) and lateral (l) domains ...

Neuromodulator Dynamics Underlying Associative Learning in the Ventral Striatum's Olfactory Tubercle [PDF]

Advanced Science
The brain's neuromodulatory systems—particularly dopamine (DA), serotonin (5‐HT), acetylcholine (ACh), and norepinephrine (NE)—play a crucial role in reward processing and associative learning. The olfactory tubercle (OT), a region that overlaps with the
