Butterfly Brain

Product Information

If you or someone you care for has any worrying symptoms that develop after brain tumour treatment, see your doctor. At first, the conditioning was lost after the caterpillars transformed into butterflies, but astonishingly, when the training was provided at later stages in the larval cycle, this aversion to ethyl acetate was retained even after the caterpillar had metamorphosized. 77% of such butterflies continued to go down the arm with fresh air when re-introduced to the Y-tube setup after their metamorphosis.

For behavioral analysis, we computed circular histograms by adding each data point of the optical encoder to the corresponding 10-degree heading bin. The animal’s preferred heading, represented by the mean vector, was computed with the CircStat toolbox in MATLAB. The flight directedness (r) was described with the mean vector strength which ranged between 0 (non-directed) to 1 (highly directed). Distributions of preferred headings of all animals were tested for uniformity with a Rayleigh test and visualized in Oriana (Version 4.01, Kovach Computing Services, Anglesey, Wales, UK). An HD index >0 indicates that the neural tuning can better be explained by a correlation with the animal’s heading (putative HD & steering neurons, n = 55), while an HD index <0 indicates that neural tuning was unaffected by the animal’s heading (putative GD neurons, n = 58). In addition, we correlated the binned neural response (10-degree bin size) measured prior to sun displacement with the one measured after displacement.

To begin to answer this question, let’s talk about brains and brain cells. As you probably know, the brain is the control center for most animals, including humans. This is where signals are sent out and received by the rest of the body. These cells can help an animal move by controlling muscles, or transmit information about its environment and make changes according to what is happening. If it is too hot, it might signal muscles to move to a shady location. If there is a predator, it might signal to hide or even change color to blend into its surroundings. Butterfly gliomas are high-grade astrocytomas, IDH-mutant or glioblastomas, IDH-wildtype that cross the midline via the corpus callosum. Other white matter commissures are also occasionally involved. The term butterfly refers to the symmetric wing-like extensions across the midline. When the developing head is completely detached from the pupa cuticle ( Figure 5H), remove the non-brain head tissue, such as the ommatidia and the facets around the visual neuropils, and the developing mouth parts on the other side of the brain. Hold the brain in place with the forceps slightly opened, while pulling the non-brain tissue away with the other hand; CC = corpus callosum; EOR = extent of resection; KPS = Karnofsky Performance Status; bGBM = butterfly glioblastoma; butterfly glioblastoma; corpus callosum glioblastoma; resection.

Lowe, T., Garwood, R. J., Simonsen, T. J., Bradley, R. S., & Withers, P. J. (2013, July 6). Metamorphosis revealed: time-lapse three-dimensional imaging inside a living chrysalis. Journal of The Royal Society Interface. The Royal Society.Glioblastoma brain tumours are sometimes called glioblastoma multiforme, GBM, GBM4 or a grade 4 astrocytoma. After studying the butterflies’ brains under a powerful microscope, researchers found that structures in the brain crucial to visual processes such as color vision and shape and motion detection are between 13 and 27% larger in the brains of the species that lives deep in the forest than in the brains of the species that lives at the forests’ edges. Another brain structure that helps process sky light and polarized light is 23% larger in the deep forest species than in the forest edges species. Previous research has also shown that the deep forest species responds to lower intensities of light, and it makes sense that species of butterflies living in darker forests would need to be more sensitive to light to see and function in dimmer conditions. Butterfly glioblastomas arguably represent the most aggressive form of glioblastoma multiforme. To date, objective assessment of a survival or clinical performance advantage in this patient population has not been performed. There is a paucity of objective data available to physicians that describe the clinical course and optimal management of this disease. Current management options include biopsy only, followed by radiation and chemotherapy; surgical decompression followed by radiation and chemotherapy; or biopsy followed by palliative measures (comfort care). Management decisions are subjective, based upon physician experience and/or patient/family preferences in light of the prognosis of this disease. The basal ganglia are a functional group of nuclei which together comprise a unit of the extrapyramidal motor system, modifying motor activity
