While the imagery of the three different stimuli did not reveal univariate activation differences, using multivariate pattern classification, we were able to decode the imagined stimulus type from BA2. The dendrites of the FeCO neurons are connected to the cuticle and. Independent of the content, during tactile mental imagery we found activation of frontoparietal regions, supplemented with activation in the contralateral BA2 subregion of S1, replicating previous reports. in the proximal femur of each Drosophila leg is a femoral chordotonal organ (FeCO). To this end, healthy volunteers ( n = 21) either perceived or imagined three types of vibrotactile stimuli (mental content) while fMRI data were acquired. Using genetic labeling, we found one of the Drosophila axonemal dynein heavy chains, CG9492 (DNAH5), was specifically expressed in larval chordotonal neurons and showed a distribution restricted. However, little is known about how they respond to sound with high sensitivity. Reduction of Pzl expression in Chordotonal neurons (iav-Gal4 >. Here, we show that the fly voltage-gated sodium channel, Para co-localizes with the TRP channels NompC and iav and a possible dendritic spike initiation zone (SIZ) in CN dendrites. Chordotonal neurons are responsible for sound sensation in Drosophila. MN dendrite position in relation to their target muscles form a myotopic map. Using fMRI and multivariate pattern analysis, we investigate whether this recruitment of sensory regions also reflects content-specific activation (i.e., whether the activation in S1 is specific to the mental content participants imagined). Several transient receptor potential (TRP) channels have been shown to localize to dendrites ofDrosophilamechanosensitive chordotonal neurons (CN). Cilia were labeled with a functional GFP-tagged NOMPB. The imagination of tactile stimulation has been shown to activate primary somatosensory cortex (S1) with a somatotopic specificity akin to that seen during the perception of tactile stimuli. A major obstacle for probing transduction in Drosophila mechanosensory neurons is the limited tractability of their transduction currents due to the small size of the neurons and their often tight wrapping by connective tissue and supporting cells, the currents can hardly be accessed 1. Download scientific diagram Antennal chordotonal neurons of wild type (A) or btv mutant (B) were stained with anti-NOMPC antiserum (red).
