Basolateral amygdala to posterior piriform cortex connectivity ensures precision in learned odor threat

open access: yesScientific Reports, 2021
Odor perception can both evoke emotional states and be shaped by emotional or hedonic states. The amygdala complex plays an important role in recognition of, and response to, hedonically valenced stimuli, and has strong, reciprocal connectivity with the ...

Synaptophysin and synaptoporin expression in the developing rat olfactory system [PDF]

open access: yes, 1993
The expressions of two closely related synaptic vesicle antigens synaptophysin and synaptoporin were examined in the olfactory system of the adult rat and during pre- and postnatal development.

INHIBITORY INTERNEURONS IN THE PIRIFORM CORTEX

open access: yesClinical and Experimental Pharmacology and Physiology, 2007
SUMMARY The piriform cortex (PC) is the largest subdivision of the olfactory cortex and the first cortical destination of olfactory information. Despite the relatively simple anatomy of the PC and its obvious appeal as a model system for the study of cortical sensory processing, there are many outstanding questions about its basic cell physiology.

Alterations in prefrontal-limbic functional activation and connectivity in chronic stress-induced visceral hyperalgesia. [PDF]

open access: yes, 2013

The cell cycle–apoptosis connection revisited in the adult brain [PDF]

open access: yes, 2005
Adult neurogenesis is studied in vivo using thymidine analogues such as bromodeoxyuridine (BrdU) to label DNA synthesis during the S phase of the cell cycle.

Olig2/Plp-positive progenitor cells give rise to Bergmann glia in the cerebellum. [PDF]

open access: yes, 2013
NG2 (nerve/glial antigen2)-expressing cells represent the largest population of postnatal progenitors in the central nervous system and have been classified as oligodendroglial progenitor cells, but the fate and function of these cells remain ...

Receptive Fields in the Rat Piriform Cortex [PDF]

open access: yesChemical Senses, 2001
Current models of odor discrimination in mammals involve molecular feature detection by a large family of diverse olfactory receptors, refinement of molecular feature extraction through precise projections of olfactory receptor neurons to the olfactory bulb to form an odor-specific spatial map of molecular features across glomerular layer, and ...

Neuromodulation and the Functional Dynamics of Piriform Cortex [PDF]

open access: yesChemical Senses, 2001
Acetylcholine and norepinephrine have a number of effects at the cellular level in the piriform cortex. Acetylcholine causes a depolarization of the membrane potential of pyramidal cells and interneurons, and suppresses the action potential frequency accommodation of pyramidal cells.

Optogenetic stimulation of lateral amygdala input to posterior piriform cortex modulates single-unit and ensemble odor processing

open access: yesFrontiers in Neural Circuits, 2015
Olfactory information is synthesized within the olfactory cortex to provide not only an odor percept, but also a contextual significance that supports appropriate behavioral response to specific odor cues.
