An Evolutionary Microcircuit Approach to the Neural Basis of High Dimensional Sensory Processing in Olfaction

open access: yesFrontiers in Cellular Neuroscience, 2021
Odor stimuli consist of thousands of possible molecules, each molecule with many different properties, each property a dimension of the stimulus. Processing these high dimensional stimuli would appear to require many stages in the brain to reach odor ...

Facilitatory actions of guanidine on synaptic transmission in mammalian brain slices [PDF]

open access: yes, 1979
Guanidine administration may be beneficial in the treatment of amyotrophic lateral sclerosis and related diseases; however, the actions of guanidine on the mammalian central nervous system have not been investigated.

Olfactory Loss and Brain Connectivity after COVID-19: Structural Follow-Up at One Year

open access: yesNeural Plasticity, 2023
The structural connectivity from the primary olfactory cortex to the main secondary olfactory areas was previously reported as relatively increased in the medial orbitofrontal cortex in a cohort of 27 recently SARS-CoV-2-infected (COV+) subjects, of ...

Cerebral Cortex Expression of Gli3 Is Required for Normal Development of the Lateral Olfactory Tract. [PDF]

open access: yesPLoS ONE, 2015
Formation of the lateral olfactory tract (LOT) and innervation of the piriform cortex represent fundamental steps to allow the transmission of olfactory information to the cerebral cortex.

Acquisition of non-olfactory encoding improves odour discrimination in olfactory cortex. [PDF]

open access: yesNat Commun, 2023
AbstractPrimary sensory cortices, initially considered elementary encoders of physicochemical attributes of environmental stimuli, are now known to be modulated by other aspects of experience, such as attentional state and internal expectations1–3, movement-related signals4–7and spatial information2, 8, 9. However, the specific role of these signals in

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.

Spatial maps in piriform cortex during olfactory navigation

open access: gold, 2020
Abstract Animals rely on chemical signals to forage for food, shelter, and mates. Such behaviors call for odor cues to be linked to locations within their environment. Nonetheless, where and how this happens in the brain is not known. Here, we show that spatial and olfactory information converge in posterior piriform cortex (pPCx), an olfactory region

Inhibition by Somatostatin Interneurons in Olfactory Cortex. [PDF]

open access: yesFront Neural Circuits, 2016
Inhibitory circuitry plays an integral role in cortical network activity. The development of transgenic mouse lines targeting unique interneuron classes has significantly advanced our understanding of the functional roles of specific inhibitory circuits in neocortical sensory processing.

Convulsant actions of 4-aminopyridine on the guinea-pig olfactory cortex slice [PDF]

open access: yes, 1982
The effects of bath-applied 4-aminopyridine on neurones and extracellular potassium and calcium concentrations were recorded in slices of guinea-pig olfactory cortex. Neurones were orthodromically activated by stimulating the lateral olfactory tract.

Perception space - The final frontier [PDF]

open access: yes, 2005
Mapping the complex sensory behavior of animals, such as smell in bees, to relevant neural activity provides clues into how animals perceive and respond to the world through their ...
