Corticofugal projections from the anterior olfactory nucleus target olfactory bulb principal cells [PDF]

open access: yes, 2011
The anterior olfactory nucleus (AON) is a cortical structure reciprocally connected with the olfactory bulb (OB) and the piriform cortex. Here, using small extracellular and intracellular injections to trace the terminal projections in the OB from ...

Comparing the Anticonvulsant Effects of Low Frequency Stimulation of Different Brain Sites on the Amygdala Kindling Acquisition in Rats

open access: yesBasic and Clinical Neuroscience, 2013
Low frequency stimulation (LFS) is a potential alternative therapy for epilepsy. However, it seems that the anticonvulsant effects of LFS depend on its target sites in the brain.

Orientation in space using the sense of smell [PDF]

open access: yes, 2010
Several studies reported that respiration interacts with olfactory perception. Therefore, in the pilot study of this experiment series human breathing was investigated during an olfactory experiment.

International Veterinary Epilepsy Task Force recommendations for systematic sampling and processing of brains from epileptic dogs and cats [PDF]

open access: yes, 2015
Traditionally, histological investigations of the epileptic brain are required to identify epileptogenic brain lesions, to evaluate the impact of seizure activity, to search for mechanisms of drug-resistance and to look for comorbidities.

Metabolic demand stimulates CREB signaling in the limbic cortex: implication for the induction of hippocampal synaptic plasticity by intrinsic stimulus for survival

open access: yesFrontiers in Systems Neuroscience, 2009
Caloric restriction by fasting has been implicated to facilitate synaptic plasticity and promote contextual learning. However, cellular and molecular mechanisms underlying the effect of fasting on memory consolidation are not completely understood.

Suppression of piriform cortex activity in rat by corticotropin-releasing factor 1 and serotonin 2A/C receptors [PDF]

open access: yes, 2015
The piriform cortex (PC) is richly innervated by Corticotropin-releasing factor (CRF) and Serotonin (5-HT) containing axons arising from central amygdala and Raphe nucleus. CRFR1 and 5-HT2A/2CRs have been shown to interact in manner where CRFR activation

A New Ensemble Learning Framework for 3D Biomedical Image Segmentation

open access: yes, 2018
3D image segmentation plays an important role in biomedical image analysis. Many 2D and 3D deep learning models have achieved state-of-the-art segmentation performance on 3D biomedical image datasets.

Increased expression of gamma-aminobutyric acid transporter-1 in the forebrain of infant rats with corticotropin-releasing hormone-induced seizures but not in those with hyperthermia-induced seizures. [PDF]

open access: yes, 2000
High affinity, gamma-aminobutyric acid (GABA) plasma membrane transporters (GATs) influence the availability of GABA, the main inhibitory neurotransmitter in the brain. Recent studies suggest a crucial role for GATs in maintaining levels of synaptic GABA

Computer Simulation of Oscillatory Behavior in Cerebral Cortical Networks [PDF]

open access: yes, 1990
It has been known for many years that specific regions of the working cerebral cortex display periodic variations in correlated cellular activity. While the olfactory system has been the focus of much of this work, similar behavior has recently been ...

Computational modeling suggests distinct, location-specific function of norepinephrine in olfactory bulb and piriform cortex

open access: yesFrontiers in Computational Neuroscience, 2015
Noradrenergic modulation from the locus coerulus is often associated with the regulation of sensory signal-to-noise ratio. In the olfactory system, noradrenergic modulation affects both bulbar and cortical processing, and has been show to modulate the ...
