visual interneurons
Non linear amplification of graded voltage signals in the first order visual interneurons of the butterfly Papilio xuthus
... Lamina monopolar cells (LMCs) are the first-order visual interneurons of insects and crustacea, primarily involved in achromatic vision. Here, we investigated morphological and electrophysiological ...

Localized direction selective responses in the dendrites of visual interneurons of the fly
... In the present study we monitored the local direction tuning of dendritic calcium signals and compared it to that obtained by axonal voltage recordings in different types of LPTCs. The VS consists of 10 neurons per brain ...

Neurovascular crosstalk between interneurons and capillaries is required for vision
... The retina is an excellent model system for studying neurovas- cular interactions in the CNS, since formation of the retinal vascu- lature and neurons occurs in well-characterized, consistent, and reproducible temporal ...

VEGF is required for dendritogenesis of newly born olfactory bulb interneurons
... A basic unanswered question is whether the effects of VEGF on dendritogenesis are direct, i.e. take place via VEGF binding to neuronally expressed VEGF receptors, or indirect, i.e. via inducing endothelial cells or ...

Murine Olfactory Bulb Interneurons Survive Infection with a Neurotropic Coronavirus
... Many viruses replicate in the nasal cavity and the olfactory epithelium, which is distinct from the respiratory epithelium, and serves as an important portal of virus entry into the CNS (1). Thus, virus is first detected ...

Rare and common epilepsies converge on a shared gene regulatory network providing opportunities for novel antiepileptic drug discovery
... Since previous studies have shown that gene modules detected in the brain often correspond to (or reflect) expression in one or more cell types [38–40], we took advantage of recently published single-cell RNA-seq data ...
