Stem Cell Niches for Olfactory Regeneration and Their Therapeutic Applications [PDF]

Journal of Rhinology
Olfactory dysfunction affects many individuals and may result from infections, trauma, neurodegenerative diseases, or genetic disorders. Unlike most neurons in the mammalian nervous system, olfactory sensory neurons (OSNs) continuously regenerate ...

Reflex seizures and epilepsy surgery: A network approach case‐based exploration

Epileptic Disorders, EarlyView.
Abstract Context Reflex seizures (RS) are defined by their consistent provocation by specific stimuli, encompassing a broad range from elementary sensory inputs to complex cognitive tasks. While RS are often encountered in clinical practice, their surgical management remains sparsely reported and poorly systematized.

Spatial maps in olfactory cortex during olfactory navigation

, 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

Subventricular zone stem cells are heterogeneous with respect to their embryonic origins and neurogenic fates in the adult olfactory bulb [PDF]

, 2007
Wedetermined the embryonic origins of adult forebrain subventricular zone (SVZ) stem cells by Cre-lox fate mapping in transgenic mice. We found that all parts of the telencephalic neuroepithelium, including the medial ganglionic eminence and lateral ...

Effects of lithium on electrical activity and potassium ion distribution in the vertebrate central nervous system [PDF]

, 1983
Three different regions of the vertebrate central nervous system maintained in vitro (frog spinal cord, guinea pig olfactory cortex and hippocampus) have been used to investigate how Li+ influences membrane potential, membrane resistance, action ...

Direct cortical stimulation–evoked symptoms in the human temporal pole: A systematic review

Epileptic Disorders, EarlyView.
Abstract The temporal pole represents a key node within temporolimbic networks and may contribute to seizure generation in temporal lobe epilepsy. Direct cortical stimulation (DCS), performed during intracranial presurgical evaluation, is a valuable method for delineating the seizure onset zone by reproducing electro‐clinical features of a patient's ...

Insulin Modulates Neural Activity of Pyramidal Neurons in the Anterior Piriform Cortex

Frontiers in Cellular Neuroscience, 2017
Insulin is an important peptide hormone that regulates food intake and olfactory function. While a multitude of studies investigated the effect of insulin in the olfactory bulb and olfactory epithelium, research on how it modulates higher olfactory ...

Electroclinical features and dynamic network connectivity of orbitofrontal epilepsy

Epilepsia, EarlyView.
Abstract Objective Orbitofrontal epilepsy (OFE) is rare and underrecognized. This study aims to characterize electroclinical features and dynamic network connectivity of OFE and subtypes. Methods We retrospectively analyzed 17 patients with OFE who underwent stereoelectroencephalographic (SEEG) electrode implantation and epilepsy surgery at our center.

Early treatment prevents neuronal loss in experimental status epilepticus: A magnetic resonance spectroscopic imaging study

Epilepsia, EarlyView.
Abstract Objective In status epilepticus there are concerns that the prolonged high‐intensity electrographic seizure activity causes neuronal death and poorer outcomes. In animal models of status epilepticus, early treatment that stops the seizures prevents the later development of epilepsy.

Host location in a specialist parasitoid wasp via olfactory cues – a physiological, behavioural and morphological study

, 2012
For successful host location, parasitoids are thought to have evolved different strategies to filter relevant olfactory cues which indicate the presence of the host. Because of their versatility in their ecology and behaviour, as well as their fine tuned
