Data for: The Neonicotinoid Imidacloprid Impairs Sucrose Solution Consumption, Learning and Locomotor Activity Levels In Bumblebees (Bombus Terrestris)
<p># README</p> <p>The following files are for creating the figures from the paper: </p> <p>## `plot_flowervisits_nectar.ipynb`</p> <p>Jupyter notebook that creates the figures concerning flower visits, nectar consumption and the proportion of empty honeypots.</p> <p>## `plot_activity.py`</p> <p>Python script that takes trajectory fragments from video analysis and computes the locomotor activity level through making histograms of bumblebee speeds. Makes two figures that are equivalent to the figure on locomotor activity in the paper.</p> <p>## `statistical analysis.py`</p> <p>R markdown notebook that performs all the hypothesis testing for the paper.</p> <p>## Data</p> <p>These files contain the data, and are located in the folder called `data`. </p> <p>`activity/activityproportions.csv` contains the computed locomotor activity level for easy plotting.</p> <p>`boldata/boldata.csv` contains data about the nectar bag weight before and after experiment and the counted number of empty and full honeypots. Used by `plot_flowervisits_nectar.ipynb`</p> <p>`flower_data/flowerData.csv` contains the computed number of visits to blue and yellow flowers per hive for easy plotting.</p> <p>`humlevideo_production/*/traj*_trajectories*.csv` contains constructed trajectories from all experiments seen from both cameras. These are being used by the script `plot_activity`.</p> <p>`humlevideo_production/*/traj*.json` contains data about the occurence of bees on flowers in each frame in each experiment.</p> <p>`landinger_csv` contains data about landings, that have been extracted from the `humlevideo_production/*/traj*.json` files.

Data from: Chemogenetic inhibition of the medial prefrontal cortex reverses the effects of REM sleep loss on sucrose consumption
Rapid eye movement (REM) sleep loss is associated with increased consumption of weight-promoting foods. The prefrontal cortex (PFC) is thought to mediate reward anticipation. However, the precise role of the PFC in mediating reward responses to highly palatable foods (HPF) after REM sleep deprivation is unclear. We selectively reduced REM sleep in mice over a 25–48 hr period and chemogenetically inhibited the medial PFC (mPFC) by using an altered glutamate-gated and ivermectin-gated chloride channel that facilitated neuronal inhibition through hyperpolarizing infected neurons. HPF consumption was measured while the mPFC was inactivated and REM sleep loss was induced. We found that REM sleep loss increased HPF consumption compared to control animals. However, mPFC inactivation reversed the effect of REM sleep loss on sucrose consumption without affecting fat consumption. Our findings provide, for the first time, a causal link between REM sleep, mPFC function and HPF consumption.
