Electrophysiological responses of rat olfactory tubercle neurons to biologically relevant odours

, 2011
International audienceBiologically relevant odours were used to stimulate olfactory tubercle neurons in anaesthetized male rats. Among 120 recordedneurons, 118 showed spontaneous activity (mean firing rate, 15.0 ± 1.4 spikes ⁄ s).

Oscillatory Sequences of Firing in the Locust Olfactory System: Mechanisms and Functional Significance [PDF]

, 1999
What neural codes does the brain use to represent and process sensory information? Stimulus-evoked oscillatory synchronization of neuronal activity has been observed in many systems, yet the possible functions of such rhythmic synchronization in neural ...

Presentation_1_Cellular Profiles of Prodynorphin and Preproenkephalin mRNA-Expressing Neurons in the Anterior Olfactory Tubercle of Mice.PDF

, 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

Multimodal Neuroimaging and Behavioral Characterization of Aged Female APOE4 Knock‐In Rats Reveals a Preclinical Alzheimer's Disease Phenotype

Genes, Brain and Behavior, Volume 25, Issue 5, October 2026.
Voxel‐based morphometry of regional brain volumes in aged female APOE4 and APOE3 knock‐in rats. APOE4 carriers present with larger brains. ABSTRACT The apolipoprotein E ε4 allele (APOE4) is the strongest genetic risk factor for sporadic Alzheimer's disease (AD) and confers disproportionate risk in women, particularly after reproductive senescence.

The Olfactory Nervous System Of Terrestrial And Aquatic Vertebrates [PDF]

, 2011
Animals in their natural milieu are surrounded by odors. These odors are rich source of information, and are perceived by sophisticated olfactory systems, that have evolved over time.

Hyperactive mTORC1 in striatum dysregulates dopamine receptor expression and odor preference behavior

Frontiers in Neuroscience
Mechanistic target of rapamycin (mTOR) plays an important role in brain development and synaptic plasticity. Dysregulation of the mTOR pathway is observed in various human central nervous system diseases, including tuberous sclerosis complex, autism ...

Spontaneous Hepatobiliary Disease in a Breeding Colony of Aotus spp.

Journal of Medical Primatology, Volume 55, Issue 5, October 2026.
ABSTRACT Background Owl monkeys are nonhuman primate species in the genus Aotus. The Michale E. Keeling Center for Comparative Medicine and Research maintains an Owl Monkey Breeding and Research Resource composed of four species of owl monkeys: Aotus nancymai, A. vociferans, A. azarae, and A. griseimembra.

Sensory memory for odors is encoded in spontaneous correlated activity between olfactory glomeruli [PDF]

, 2006
Sensory memory is a short-lived persistence of a sensory stimulus in the nervous system, such as iconic memory in the visual system. However, little is known about the mechanisms underlying olfactory sensory memory.

Differential potentiation of odor aversion and yawning by melanocortin 4 receptor signaling in distinct regions of the ventral striatum

Frontiers in Neuroscience
Although animal behavior is influenced by neuromodulatory signals, the underlying mechanism remains elusive. The ventral striatum, which consists of the olfactory tubercle (OT) and nucleus accumbens (NAc), promotes motivated behaviors and receives ...

Liver cirrhosis is associated with altered glucocorticoid metabolism related to disease severity

Journal of Internal Medicine, Volume 300, Issue 4, Page 513-527, October 2026.
Abstract Background Liver cirrhosis (LC) is frequently complicated by adrenal dysfunction; however, whether cirrhosis drives the coordinated, pathway‐specific reprogramming of cortisol metabolism remains unclear. Objectives We aimed to characterize axis‐specific alterations in cortisol metabolism in patients with LC, those with adrenal insufficiency ...
