Optophysiological analysis of pattern classification strategies in the zebrafish olfactory bulb [PDF]

, 2012
Classification of overlapping activity patterns is a common problem for sensory systems. For a robust representation of sensory stimuli, neuronal circuits should generalize over input patterns reflecting variations of the same stimulus but separate ...

The olfactory functional network in the Alzheimer’s disease continuum: a resting state fMRI study

Frontiers in Aging Neuroscience
IntroductionOlfactory dysfunction is common in the Alzheimer’s Disease continuum, and olfaction may be altered before clinical syndrome onset. The present study aimed at investigating the functional connectivity of the olfactory cortex and its ...

Glycobiology of the olfactory system [PDF]

, 1998
The olfactory system is a highly plastic region of the nervous system. Continuous remodeling of neuronal circuits in the olfactory bulb takes place throughout life as a result of constant turnover of primary sensory olfactory neurons in the periphery ...

Blood–Brain Barrier Regulation: Evolving From Classic Strategies to Electrochemical Ion and Reactive Oxygen Species Control

Advanced Healthcare Materials, EarlyView.
Conventional therapies suffer from poor blood–brain barrier (BBB) penetration and disordered ion/reactive oxygen species (ROS) homeostasis, hindering precise neurological treatment. Electrochemical strategies achieve accurate spatiotemporal regulation of neural homeostasis.

Orientation in space using the sense of smell [PDF]

, 2010
Several studies reported that respiration interacts with olfactory perception. Therefore, in the pilot study of this experiment series human breathing was investigated during an olfactory experiment.

Acquired olfactory loss alters functional connectivity and morphology

Scientific Reports, 2021
Removing function from a developed and functional sensory system is known to alter both cerebral morphology and functional connections. To date, a majority of studies assessing sensory-dependent plasticity have focused on effects from either early onset ...

Odor identity coding by distributed ensembles of neurons in the mouse olfactory cortex

eLife, 2017
Olfactory perception and behaviors critically depend on the ability to identify an odor across a wide range of concentrations. Here, we use calcium imaging to determine how odor identity is encoded in olfactory cortex.
