A descending interneuron in the cricket brain, with prominent dendrites in the deutocerebrum, receives input from three sensory modalities: touch of the antennal flagellum, strain of the antennal base, and visual stimulation. Using calcium imaging, we demonstrate that each modality drives a Ca<jats:sup>2+<\/jats:sup>increase in a different dendritic region. Moreover, touch of the flagellum is represented in a topographic map along the neuron\u2019s dendrites. Using intracellular recording, we investigated the effects of Ca<jats:sup>2+<\/jats:sup>on spike shape through the application of the Ca<jats:sup>2+<\/jats:sup>channel antagonist Cd<jats:sup>2+<\/jats:sup>and identified probable Ca<jats:sup>2+<\/jats:sup>-dependent K<jats:sup>+<\/jats:sup>currents.<\/jats:p><jats:p>NEW &amp; NOTEWORTHY Different dendritic regions of the cricket brain neuron DBNi1-2 showed localized Ca<jats:sup>2+<\/jats:sup>increases when three modalities of stimulation (touch of the flagellum, strain at antennal base, and visual input) were given. Touch stimulation induces localized Ca<jats:sup>2+<\/jats:sup>increases according to a topographic map of the antenna.
