Involvement of right piriform cortex in olfactory familiarity judgments [PDF]

NeuroImage, 2005
Previous studies have shown activation of right orbitofrontal cortex during judgments of odor familiarity. In the present study, we sought to extend our knowledge about the neural circuits involved in such a task by exploring the involvement of the right prefrontal areas and limbic/primary olfactory structures.

Cell-Type-Specific Whole-Brain Direct Inputs to the Anterior and Posterior Piriform Cortex

Frontiers in Neural Circuits, 2020
The piriform cortex (PC) is a key brain area involved in both processing and coding of olfactory information. It is implicated in various brain disorders, such as epilepsy, Alzheimer’s disease, and autism.

Multi-stage Multi-recursive-input Fully Convolutional Networks for Neuronal Boundary Detection [PDF]

, 2017
In the field of connectomics, neuroscientists seek to identify cortical connectivity comprehensively. Neuronal boundary detection from the Electron Microscopy (EM) images is often done to assist the automatic reconstruction of neuronal circuit.

The Sense of Smell (SoS) Atlas: Its Creation and First Application to Investigate COVID‐19 Related Anosmia With a Comprehensive Quantitative MRI Protocol

Journal of Magnetic Resonance Imaging, Volume 63, Issue 2, Page 574-593, February 2026.
ABSTRACT Background The loss of smell (anosmia) has been noted in numerous diseases, including COVID‐19. Inflammatory and microstructural alterations are possible underlying mechanisms of anosmia in COVID‐19. However, no atlas exists to study olfaction and the associated tissue property changes.

Chromogranin A in the olfactory system of the rat [PDF]

, 1990
The olfactory bulb of the rat contains chromogranin A at a similar level as the adrenal gland or the hypophysis as revealed by immunoblots. Olfactory chromogranin A also displays the same size as chromogranin A of endocrine cells.

Hippocampal Chandelier Cells Modulate Seizure Susceptibility and Severity

Advanced Science, Volume 13, Issue 4, 19 January 2026.
The axon initial segment (AIS), crucial for action potential initiation, serves as a prime locus for controlling network activity. Chandelier Cells (ChCs), evolved in the mammals, intricately target AISs, acting as gatekeepers for neuronal firing. Diminishing ChC input makes animals more prone to developing seizures, whereas fortifying this connection ...

A receptor-based analysis of local ecosystems in the human brain. [PDF]

, 2017
BackgroundAs a complex system, the brain is a self-organizing entity that depends on local interactions among cells. Its regions (anatomically defined nuclei and areas) can be conceptualized as cellular ecosystems, but the similarity of their functional ...

Longitudinal MRI Characterization of T1 and T2 Relaxation Times in an Amyloid Mouse Model of Alzheimer's Disease at 11.7 T

NMR in Biomedicine, Volume 39, Issue 1, January 2026.
In this study, we systematically characterized the longitudinal evolution of T1 and T2 relaxation times at the early to middle stage of Tg2576 mouse model representing the amyloidosis subtype of Alzheimer’s disease. We found that rates of change in relaxation times within the thalamus, hypothalamus, and piriform cortex may serve as markers for ...

Learning to smell danger: Acquired associative representation of threat in the olfactory cortex

Frontiers in Behavioral Neuroscience, 2014
Neuroscience research over the past few decades has reached a strong consensus that the amygdala plays a key role in emotion processing. However, many questions remain unanswered, especially concerning emotion perception.
