An increasing diversity of techniques investigating the biology of specific cell types and individual cells have elevated the importance of dissociation of viable cells from living tissues. Here we describe a method for the dissociation of single cells from samples of adult mouse olfactory mucosae, with an emphasis on maximizing yield of viable single cells from fluorescence-activated cell sorting. Yields are typically in the range of 80,000-150,000 viable cells per adult mouse.

Organisms continually tune their perceptual systems to the features they encounter in their environment . We have studied how ongoing experience reorganizes the synaptic connectivity of neurons in the olfactory (piriform) cortex of the mouse. We developed an approach to measure synaptic connectivity , training a deep convolutional network to reliably identify monosynaptic connections from the spike-time cross-correlograms of 4.

Transient Receptor Potential Melastatin 8 (TRPM8) is a non-selective, Ca-permeable cation channel involved in thermoregulation and other physiological processes, such as basal tear secretion, cell differentiation, and insulin homeostasis. The activation and deactivation of TRPM8 occur through genetic modifications, channel interactions, and signaling cascades. Recent evidence suggests a significant role of TRPM8 in the hypothalamus and amygdala related to pain sensation and sexual behavior.

Fragile X syndrome (FXS) is a neurodevelopmental disorder oftentimes associated with abnormal social behaviors and altered sensory responsiveness. It is hypothesized that the inappropriate filtering of sensory stimuli, including olfaction, can lead to aberrant social behavior in FXS. However, previous studies investigating olfaction in animal models of FXS have shown inconsistent results.

Iron is the most abundant transition metal in the brain and is essential for brain development and neuronal function; however, its abnormal accumulation is also implicated in various neurological disorders. The olfactory bulb (OB), an early target in neurodegenerative diseases, acts as a gateway for environmental toxins and contains diverse neuronal populations with distinct roles. This study explored the cell-specific vulnerability to iron in the OB using a mouse model of intranasal administration of ferric ammonium citrate (FAC).
