Neuronal counts of the Anterior Piriform Cortex in 6 mammals

, 2019
This repository contains Neurolucida files showing the density counts for 6 species of mammals (across 12 animals). The data set can also be used for estimating the volumes and surface areas of anterior piriform cortex, as a well as an analysis of neuron

Smell-induced gamma oscillations in human olfactory cortex are required for accurate perception of odor identity.

PLoS Biology, 2022
Studies of neuronal oscillations have contributed substantial insight into the mechanisms of visual, auditory, and somatosensory perception. However, progress in such research in the human olfactory system has lagged behind.

Neonatal seizures and GABAergic drugs: Scylla and Charybdis?

Epilepsia Open, EarlyView.
Abstract Neonates have a high incidence of seizures that are frequently difficult to control with conventional first‐line anti‐seizure medications, which are gamma‐aminobutyric acid (GABA) agonists. The reasons for this clinical problem are multifold but are likely related to the unique physiology of the immature nervous system. Specifically, the early

Olfactory tract transection enhances adult neurogenesis in piriform cortex

, 2009
Adult neurogenesis happens continuously in olfactory bulb. Loss of sensory input to the olfactory bulb leads to decreased formation of new neurons in the bulb.

A hypothesis for the evolution of the upper layers of the neocortex through co-option of the olfactory cortex developmental program.

Frontiers in Neuroscience, 2015
The neocortex is unique to mammals and its evolutionary origin is still highly debated. The neocortex is generated by the dorsal pallium ventricular zone, a germinative domain that in reptiles give rise to the dorsal cortex.

The basal ganglia and the epilepsies

Epilepsia Open, EarlyView.
Abstract The basal ganglia are an evolutionarily conserved neural circuit best known for the selection and sequencing of voluntary movement. Increasing evidence, however, indicates that these structures also play an important role in regulating pathological brain states, including seizures.

The Associations Between Olfactory Bulb Morphology, Volume Change, and Olfactory Recovery

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective To investigate whether olfactory bulb (OB) morphology is associated with olfactory recovery following olfactory training (OT) in individuals with COVID‐19‐related smell loss. Study Design Prospective observational study. Setting University hospital and research center.

Broadcasting of Cortical Activity to the Olfactory Bulb

Cell Reports, 2015
Odor representations are initially formed in the olfactory bulb, which contains a topographic glomerular map of odor molecular features. The bulb transmits sensory information directly to piriform cortex, where it is encoded by distributed ensembles of ...

Anticipation-induced delta phase reset improves human olfactory perception.

PLoS Biology, 2020
Anticipating an odor improves detection and perception, yet the underlying neural mechanisms of olfactory anticipation are not well understood. In this study, we used human intracranial electroencephalography (iEEG) to show that anticipation resets the ...

Expression of GABAergic and glutamatergic neurons after olfactory stimulation in the mouse piriform cortex during postnatal development

Анналы клинической и экспериментальной неврологии, 2022
Introduction. The control of the survival and differentiation of immature neurons in the piriform cortex of rodents, which can transform into GABAergic and/or glutamatergic neurons under the influence of olfactory stimuli, is an important factor for ...
