Rapid and efficient escape behaviors in response to noxious sensory stimuli are essential for protection survival. Yet, how transformed coordinated remains poorly understood. In Drosophila larvae, trigger sequential body bending corkscrew-like rolling behavior. We identified a population of interneurons the nerve cord Drosophila, termed Down-and-Back (DnB) neurons, that activated by heat, promote nociceptive behavior, required robust responses stimuli. Electron microscopic circuit...
Vision is altered when people place their hands near the object they are observing. To investigate neural processes underlying this effect, we measured electroencephalographic visual-evoked potentials (VEPs) elicited by reversing checkerboards, while participants' either surrounded visual display or rested at sides. We found P2 component was attenuated for hand-proximal stimuli, but only participants attended to location of checkerboard. In Experiment 1, performed an attention-demanding...
Abstract Signaling at nicotinic acetylcholine receptors in Caenorhabditis elegans controls many behaviors, including egg‐laying and locomotor activity. Here, we show that C. approaches a point source of nicotine time‐, concentration‐ age‐dependent manner. Additionally, paired with butanone under starvation conditions prevented the reduced approach to is observed when alone pairing generates preference for tastes either sodium or chloride over baseline. These results suggest acts as rewarding...
Internal sensory neurons innervate body organs and provide information about internal state to the CNS maintain physiological homeostasis. Despite their conservation across species, anatomy, circuitry, development of systems are still relatively poorly understood. A largely unstudied population larval Drosophila neurons, termed tracheal dendrite (td) respiratory may serve as a model for understanding sensing states. Here, we characterize peripheral central axon projection, diversity td...
Internal sensory neurons monitor the chemical and physical state of body, providing critical information to central nervous system for maintaining homeostasis survival. A population larval
