Bilateral Alignment of Receptive Fields in the Olfactory Cortex
bioRxiv, 2020 Each olfactory cortical hemisphere receives ipsilateral odor information directly from the olfactory bulb and contralateral information indirectly from the other cortical hemisphere. Since neural projections to the olfactory cortex are disordered and non-

Disinhibitory Circuitry Gates Associative Synaptic Plasticity in Olfactory Cortex
Journal of Neuroscience, 2020 Inhibitory microcircuits play an essential role in regulating cortical responses to sensory stimuli. Interneurons that inhibit dendritic or somatic integration act as gatekeepers for neural activity, synaptic plasticity, and the formation of sensory ...

NeuroImage, 2021 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.

Frontiers 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 ...

Neural Mechanisms of Selective Auditory Attention in Rats (Dissertation) [PDF]
, 2008 How does attention modulate sensory representations? In order to probe the underlying neural mechanisms, we established a simple rodent model of modality-specific attention.

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

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

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