An extrahippocampal projection from the dentate gyrus to the olfactory tubercle [PDF]

BMC Neuroscience, 2005
Background The dentate gyrus is well known for its mossy fiber projection to the hippocampal field 3 (CA3) and its extensive associational and commissural connections.

Whole-Brain Mapping of the Inputs and Outputs of the Medial Part of the Olfactory Tubercle [PDF]

Frontiers in Neural Circuits, 2017
The medial part of the olfactory tubercle (OT) is a brain structure located at the interface of the reward and olfactory system. It is closely related to pheromone-rewards, natural reinforcement, addiction and many other behaviors. However, the structure

Phasic dopamine reinforces distinct striatal stimulus encoding in the olfactory tubercle driving dopaminergic reward prediction [PDF]

Nature Communications, 2020
It is not entirely understood how network plasticity produces the coding of predicted value during stimulus-outcome learning. Here, the authors reveal a reinforcing loop in distributed limbic circuits, transforming sensory stimuli into reward prediction ...

Opposing Roles of Dopamine Receptor D1- and D2-Expressing Neurons in the Anteromedial Olfactory Tubercle in Acquisition of Place Preference in Mice [PDF]

Frontiers in Behavioral Neuroscience, 2019
Olfaction induces adaptive motivated behaviors. Odors associated with food induce attractive behavior, whereas those associated with dangers induce aversive behavior.

Activation of the dopaminergic pathway from VTA to the medial olfactory tubercle generates odor-preference and reward [PDF]

eLife, 2017
Odor-preferences are usually influenced by life experiences. However, the neural circuit mechanisms remain unclear. The medial olfactory tubercle (mOT) is involved in both reward and olfaction, whereas the ventral tegmental area (VTA) dopaminergic ...

The Connections of the Telencephalic Pallium in the White Sturgeon, Acipenser transmontanus: An Experimental Study. [PDF]

J Comp Neurol
Sturgeons are an ancient and basal group of ray‐finned fishes whose pallium consists of lateral, medial, and posterior divisions. The connections of these divisions were determined by injections of biotinylated dextran amine and DiI. Although there is considerable overlap in the connections of these pallial divisions, their heaviest connections are ...

Whole-Brain Monosynaptic Inputs to and Axonal Projections From Posterior Insular Cortex GABAergic Neurons in Mice. [PDF]

CNS Neurosci Ther
We mapped whole‐brain inputs and outputs of PIC GABAergic neurons. This study revealed that PIC GABAergic neurons receive dense inputs from the isocortex and thalamus and send strong projections to the basal ganglia and amygdala, with these regions constituting key hubs of the connectivity network.

Olfactory tubercle mediates adaptive social behavior by controlling threat assessment and the expression of social threat memories during recall in male mice [PDF]

Nature Communications
The ability to dynamically assess and update threat responses based on changing environmental contexts is fundamental for survival. Here, we developed an odor-based paradigm where male mice encounter a restrained conspecific that subsequently becomes ...

Olfactory tubercle stimulation alters odor preference behavior and recruits forebrain reward and motivational centers [PDF]

Frontiers in Behavioral Neuroscience, 2014
Rodents show robust behavioral responses to odors, including strong preferences or aversions for certain odors. The neural mechanisms underlying the effects of odors on these behaviors in animals are not well understood. Here, we provide an initial proof-

Neurochemical organization of the ventral striatum's olfactory tubercle. [PDF]

J Neurochem, 2020
AbstractThe ventral striatum is a collection of brain structures, including the nucleus accumbens, ventral pallidum and the olfactory tubercle (OT). While much attention has been devoted to the nucleus accumbens, a comprehensive understanding of the ventral striatum and its contributions to neurological diseases requires an appreciation for the complex
