Rhythmic Spontaneous Activity in the Piriform Cortex [PDF]
Slow spontaneous rhythmic activity is generated and propagates in neocortical slices when bathed in an artificial cerebrospinal fluid with ionic concentrations similar to the ones in vivo. This activity is extraordinarily similar to the activation of the cortex in physiological conditions (e.g., slow-wave sleep), thus representing a unique in vitro ...

Top-down feedback enables flexible coding strategies in the olfactory cortex
Summary: In chemical sensation, multiple models have been proposed to explain how odors are represented in the olfactory cortex. One hypothesis is that the combinatorial identity of active neurons within sniff-related time windows is critical, whereas ...

Neurons and circuits for odor processing in the piriform cortex [PDF]
Increased understanding of the early stages of olfaction has lead to a renewed interest in the higher brain regions responsible for forming unified ‘odor images’ from the chemical components detected by the nose.

Representations of Odor in the Piriform Cortex [PDF]
Olfactory perception is initiated by the recognition of odorants by a large repertoire of receptors in the sensory epithelium. A dispersed pattern of neural activity in the nose is converted into a segregated map in the olfactory bulb. How is this representation transformed at the next processing center for olfactory information, the piriform cortex ...

Complementary Sensory and Associative Microcircuitry in Primary Olfactory Cortex [PDF]
The three-layered primary olfactory (piriform) cortex is the largest component of the olfactory cortex. Sensory and intracortical inputs converge on principal cells in the anterior piriform cortex (aPC).Wecharacterize organization principles of the ...

The piriform cortex receives input from the olfactory bulb and (via the entorhinal cortex) sends efferents to the hippocampus, thereby connecting the two canonical neurogenic regions of the adult rodent brain.

Nonsensory target-dependent organization of piriform cortex [PDF]
Significance The mammalian olfactory system is capable of detecting and discriminating a vast and diverse array of small organic molecules or odorants. Complex blends of these chemicals are finally perceived as a unified odor object—for example, a rose contains dozens of active compounds.

Olfaction could prove to be an early marker of neurodegenerative diseases, including Alzheimer's and Parkinson's diseases. To use olfaction for disease diagnosis, elucidating the standard olfactory functions in healthy humans is necessary.

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

Circuit-specific dendritic development in the piriform cortex [PDF]
AbstractDendritic geometry is largely determined during postnatal development and has a substantial impact on neural function. In sensory processing, postnatal development of the dendritic tree is affected by two dominant circuit motifs, ascending sensory feedforward inputs and descending and local recurrent connections.
