Figure Lengend Snippet: Sensors for monitoring behavior and artifacts (A) An accelerometer sensor can be attached to the index finger of the participant to monitor behavioral outcomes. (B) Electromyogram (EMG) electrodes can be added to any of the 3 holders (left E1, mid E2 and right E3), to monitor muscle artifacts. (C) Electrooculogram (EOG) electrodes can be placed vertically and horizontally to monitor eye movement artifacts.

Figure Lengend Snippet: A) The number of hits (correct responses), errors, misses and false alarms as a function of target-flanker distance with standard error of the mean (SEM) from a total of 64 target events per condition. B) Average proportion correct in different target-flanker distances fitted with a Gaussian function. 90% of the asymptote indicated as the critical spacing. Median (red dotted line) and 95% confidence intervals (grey area) of the critical spacings based on 1000 bootstrapped means. C) Average response time in correct trials across participants. D) Grand-average amplitude spectrum obtained by Fourier transform separately for each condition collapsed across occipital electrodes (P04, P08, P6, CP6, P8, P03, P07, P5, CP5, P7 Oz, POz, O2, Iz and O1). Amplitudes peak at simulation frequencies 10, 12 and 15 Hz, however, these peaks are more pronounced when stimulus-specific electrodes are chosen. Topographic maps of SSVEP amplitudes for each stimulus at simulation frequencies averaged across all subjects and conditions (electrode positions chosen for analysis indicated with circles). E) Average normalized target-related amplitudes from five highest amplitude electrodes for each frequency separately, fitted identically to the behavioural data with critical spacing (black dotted line). Median (red dotted line) and 95% confidence intervals (grey area) of the critical spacings based on 1000 bootstrapped means.

Article Title: Synergistic behavioral antagonists of a sex pheromone reduce reproduction of invasive sea lamprey

doi: 10.1016/j.isci.2023.107744

Figure Lengend Snippet: 3sPZS stimulated the olfactory system at picomolar concentrations (A–G) Responses were measured by electro-olfactogram recordings (EOG) in adult sea lamprey. Data are represented as mean ± SEM. (A) 3sPZS, (B) PZS, and (C) 3kPZS induced concentration-dependent responses. (Inset) Structures of 3sPZS, PZS, and 3kPZS. The response amplitude was blank-corrected and normalized to the response amplitude of 10 −5 M L -arginine (standard). Inset in (A) shows re-scaled y axis to best show the trend of the data. The EOG response to (D) 3sPZS were not different in males and females. (E) 3sPZS reduced the olfactory response to 3kPZS but not to a non-pheromone control stimulus that elicits olfactory responses, L-arginine, in males and females. A ratio of EOG amplitude value of 1.0 indicates 3sPZS did not reduce the olfactory response to the test stimuli. Significance between sexes was evaluated with two-tailed t test. Representative EOG traces of (F) female and (G) male olfactory epithelia exposed to 3sPZS at concentrations between 10 −12 M and 10 −6 M from (A). The number above each trace is the logarithmic value of the molar concentration of each stimulant. The bar above the L-ARG trace ( Left ) represents the duration of odorant treatment. Blank, vehicle solution; L-ARG, L-arginine.
