Genetic Control of Active Neural Circuits
The use of molecular tools to study the neurobiology of complex behaviors has been hampered by an inability to target the desired changes to relevant groups of neurons. Specific memories and specific sensory representations are sparsely encoded by a small fraction of neurons embedded in a sea of morphologically and functionally similar cells. In this review we discuss genetics techniques that a...
متن کاملGenetic control of astrocyte function in neural circuits
During the last two decades numerous genetic approaches affecting cell function in vivo have been developed. Current state-of-the-art technology permits the selective switching of gene function in distinct cell populations within the complex organization of a given tissue parenchyma. The tamoxifen-inducible Cre/loxP gene recombination and the doxycycline-dependent modulation of gene expression ...
متن کاملGenetic Dissection of Neural Circuits
Understanding the principles of information processing in neural circuits requires systematic characterization of the participating cell types and their connections, and the ability to measure and perturb their activity. Genetic approaches promise to bring experimental access to complex neural systems, including genetic stalwarts such as the fly and mouse, but also to nongenetic systems such as...
متن کاملA genetic approach to trace neural circuits.
Mammalian nervous system function involves billions of neurons which are interconnected in a multitude of neural circuits. Here we describe a genetic approach to chart neural circuits. By using an olfactory-specific promoter, we selectively expressed barley lectin in sensory neurons in the olfactory epithelium and vomeronasal organ of transgenic mice. The lectin was transported through the axon...
متن کاملRegulating peptidergic modulation of rhythmically active neural circuits.
The ability of neuropeptides to modulate neural circuit activity is well established, but little is known regarding how the actions of neurally-released peptides are regulated. This issue is being studied in the isolated stomatogastric nervous system (STNS) of decapod crustaceans. The STNS is a small neural system that contains the rhythmically active gastric mill (chewing) and pyloric (filteri...
