Psychology dendrite function8/18/2023 ![]() ![]() Dendritic spikes enhance stimulus selectivity in cortical neurons in vivo. Smith S.L., Smith I.T., Branco T., Hausser M. Wide field-of-view, multi-region, two-photon imaging of neuronal activity in the mammalian brain. Stirman J.N., Smith I.T., Kudenov M.W., Smith S.L. Dendrites are short branched extensions of a neuron where impulses are received in the synapses and transmitted to the soma. Stream-dependent development of higher visual cortical areas. Smith I.T., Townsend L.B., Huh R., Zhu H., Smith S.L. ![]() Mice use robust and common strategies to discriminate natural scenes. Yu Y, Hira R, Stirman J.N., Yu W, Smith I.T., Smith S.L. We seek to understand how dendrites contribute to synaptic computations and how their excitability is modified by the local microcircuitry in a state-dependent manner. In my lab, we employ direct patch clamp recordings from fine distal dendrites to examine their patterns of electrical activity during visual behavior. Whether such an active mechanism is engaged and plays a functional role in behaving animals, remains unclear. Such thresholded spiking allows dendrites to serve as transistors rather than passive cables and vastly increases the computational power of a single neuron. Much like axons, dendrites are capable of firing electrical spikes. One of my key interests is to understand the role of neuronal dendrites in processing information. My work focuses on uncovering the underpinnings of such processes using electrophysiology, two-photon imaging, intrinsic signal optical imaging and behavioral analyses. During sensory perception, neural circuitry processes information by filtering, amplifying, and integrating electrical signals. My primary research goal is to elucidate the cellular and network mechanisms by which neural circuitry functions. Dendrite definition: any of the short branched threadlike extensions of a nerve cell, which conduct impulses Meaning, pronunciation, translations and examples Dendrite definition is a branching treelike figure produced on or in a mineral by a foreign mineral Examples of dendrite in a Sentence. Her lab will investigate the functional role of neural dendrites in synaptic computations. She completed two postdoctoral fellowships at University College London and University of North Carolina School of Medicine where she studied developmental synaptic competition in the cerebellum and functional development of the neural circuitry in the visual cortex, respectively. in Physiology from the University of California, Los Angeles. As such, they are part of the sensory pathways for smell, sight, taste, hearing, touch, balance. Many bipolar cells are specialized sensory neurons for the transmission of sense. A bipolar neuron, or bipolar cell, is a type of neuron that has two extensions (one axon and one dendrite ). Ikuko Smith received her DVM from Hokkaido University School of Veterinary Medicine in Japan and Ph.D. Dendrite A neuron fiber that receives signals from the axons of other neurons and carries those signals to the cell body. Bipolar nerve cell from the spinal ganglion of the pike. ![]()
