“…For visualising the location of neurons in the praying mantis' brains we superimposed the neurons on schemes of mantis brains and adjusted the shape of the schematised brain and in some cases also neuropils to better capture individual differences between animals and distortions of the brains caused by the preparation procedure after the electrophysiological experiments. The schemes of the mantis brains were modified versions of those used in Rosner et al (2019) and the registration of the neurons onto these schemes was done in Adobe Illustrator CC 2018 (Adobe Systems, Ireland).…”

“…For simulating response fields we applied a "linear/non-linear" (LN) model used for modelling simple cell responses in vertebrate stereopsis (the simple cell model in (Ohzawa et al 1990), generalised to allow arbitrary receptive fields and output exponent) and insect stereopsis (Rosner et al 2019). This model assumes that visual stimulation contributes excitatory or inhibitory input dependent on the eye and location of the stimulation, that is, the model contains receptive fields for both the left and the right eye.…”

“…Note that we use the term response field to mean the measured average spiking rate of the neuron to bar stimuli at the specified location; we keep the term receptive field to refer to the linear part of the function governing this response, which is not directly observable. The fitting procedure was exactly the same as in Rosner et al (2019). Specifically, we fitted the model to the mean neuronal response, that is, to the normalized spike count, D ij , where i, j indexes the stimulus present in left, right eyes.…”

“…Neurons suited to do this computation are called disparity sensitive. They have been found in the visual cortices of cats and monkeys (Cumming and DeAngelis 2001;Parker 2007) and more recently in the praying mantis brain (Rosner et al 2019). So far, four neuron types have been described that are tuned to specific retinal disparities.…”

Praying mantids are the only insects proven to have stereoscopic vision (stereopsis): the ability to perceive depth from the slightly shifted images seen by the two eyes. Recently, the first neurons likely to be involved in mantis stereopsis were described and a speculative neuronal circuit suggested. Here we further investigate classes of neurons in the lobula complex of the praying mantis brain and their tuning to stereoscopically-defined depth. We used sharp electrode recordings with tracer injections to identify visual projection neurons with input in the optic lobe and output in the central brain. In order to measure binocular response fields of the cells the animals watched a vertical bar stimulus in a 3D insect cinema during recordings. We describe the binocular tuning of 19 neurons projecting from the lobula complex and the medulla to central brain areas. The majority of neurons (12/19) were binocular and had receptive fields for both eyes that overlapped in the frontal region. Thus, these neurons could be involved in mantis stereopsis. We also find that neurons preferring different contrast polarity (bright vs dark) tend to be segregated in the mantis lobula complex, reminiscent of the segregation for small targets and widefield motion in mantids and other insects.

Many predatory animals, such as the praying mantis, use vision for prey detection and capture. Mantises are known in particular for their capability to estimate distances to prey by stereoscopic vision. While the initial visual processing centers have been extensively documented, we lack knowledge on the architecture of central brain regions, pivotal for sensory motor transformation and higher brain functions. To close this gap, we provide a three‐dimensional (3D) reconstruction of the central brain of the Asian mantis, Hierodula membranacea. The atlas facilitates in‐depth analysis of neuron ramification regions and aides in elucidating potential neuronal pathways. We integrated seven 3D‐reconstructed visual interneurons into the atlas. In total, 42 distinct neuropils of the cerebrum were reconstructed based on synapsin‐immunolabeled whole‐mount brains. Backfills from the antenna and maxillary palps, as well as immunolabeling of γ‐aminobutyric acid (GABA) and tyrosine hydroxylase (TH), further substantiate the identification and boundaries of brain areas. The composition and internal organization of the neuropils were compared to the anatomical organization of the brain of the fruit fly (Drosophila melanogaster) and the two available brain atlases of Polyneoptera—the desert locust (Schistocerca gregaria) and the Madeira cockroach (Rhyparobia maderae). This study paves the way for detailed analyses of neuronal circuitry and promotes cross‐species brain comparisons. We discuss differences in brain organization between holometabolous and polyneopteran insects. Identification of ramification sites of the visual neurons integrated into the atlas supports previous claims about homologous structures in the optic lobes of flies and mantises.
