Despite having small brains, insects’ cognitive abilities are impressive. They can process a large set of information from their environment and adjust their behaviour accordingly [ 1]. Many species possess remarkable learning and memorisation skills [ 2, 3]. Examples of sophisticated behaviours include concept and category learning in honeybees [ 4], tool use in ants [ 5], facial pattern recognition in wasps [ 6, 7], and counting ability in bees [ 8, 9]. If you’ve just been diagnosed and are about to have treatment, you may want to see what other people’s first treatment was. Use the First Treatment insight in BRIAN, which you can personalise to make it relevant to you. All Karnofsky performance scores (KPS) utilized for the purposes of this study were recorded by either a neuro-oncologist or neurosurgeon, or estimated from the medical record based upon the dictated details of the patient’s functional status. Scores at the time of diagnosis, before, and after radiation therapy (XRT) are included. These scores represented the most consistent time points in which functional status was measured in the medical record. Tumor functional grade had been prospectively determined at presentation as described by Sawaya et al. [ 14]. Tumor volume had also been prospectively determined by volumetric analysis of individual patient MRIs using Vitrea 3.5 software (Vital Images, Inc., Minnetonka, MN). For the purpose of this paper and to provide a more accurate description of tumor mass, tumor volume was defined as the sum of T1 enhancement plus necrosis volume. Tumor flair volume data were also included. Extent of resection (EOR) represented the percentage reduction in T1 enhancing tumor volume on post-operative MRIs. Survival time was defined as the number of days from the time of diagnosis to date of death. Adjuvant therapy was defined as any treatment after the procedure (biopsy or decompression) and before progression, and consisted of XRT only, or radiation and chemotherapy.

Remove any remaining trachea by pulling gently with a curved forceps ( Figure 4G), while pressing the brain down with an insect pin or by using insect pins to scrape them off the brain tissue ( Figure 4H); Descending pathways control the movements of the body. They are classified in two large groups; pyramidal and extrapyramidal. The pyramidal motor system (corticonuclear and corticospinal pathways) originates from the motor cortex to control voluntary movements of skeletal muscles. onion bulb nerves: Charcot-Marie-Tooth type 1A and chronic inflammatory demyelinating polyneuropathies We have seen similar results in human beings who spend their days completing visual and spatial awareness tasks, such as taxi drivers who show an increase in brain size after learning multiple routes around the city. So, the next time you drive to the supermarket or meander towards your favorite café, think about all the ways humans and our insect counterparts may be experiencing brain evolution. Especially as the impacts of climate change and human development reduce food sources for butterflies and humans, it is critical we remember the importance of finding fresh, nutrient-rich food.

Close your eyes and picture your route to the grocery store. As you visualize the curves of the road and the street signs you pass, you are using the region of your brain called the hippocampus. As you navigate, you are tracing paths between neurons in your brain, mapping memories called engrams. The more times a day you do this, the more connections you make and the stronger your visual memory will be. The researchers then placed the caterpillars at the bottom of a Y-shaped tube that had ethyl alcohol fumes in one arm and no scent in the other. 78% of the conditioned larvae crawled away from the scented arm and into the one with fresh air.

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 Brains And Speciation | A Moment of Science

It doesn’t have to be that way. In this article we will introduce you to the main concepts of neuroanatomy and the major structures of the nervous system. After that, you can dive into our series of easy-to-read study materials, so that at the end of your neuroanatomy journey you’ll feel more like Frodo Baggins, rather than the fallen Boromir. Key facts about neuroanatomy Nervous system Here, we describe the process of larval, pupal, and adult butterfly brain removal using a video. We also provide a complete written description of the processes, with a list of necessary tools and chemicals. The dissection methods can be applied to different butterfly species, and the brains can be used for DNA or RNA extraction, or for immunostaining. We record the dissection process in the Bush brown butterfly Bicyclus anynana, which is especially interesting due to its plastic and sex-role reversed courtship behaviour [ 43, 44, 45, 46]. Individuals are also capable of learning visual and olfactory cues [ 47, 48, 49], and they can transmit the learned odour preferences to their offspring [ 48, 49]. Because the molecular basis of these unique behaviours can begin to be examined at the level of the brain, it is important to extract this organ for downstream analyses. 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; 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.

carmustine implants (glial wafers) – a new way of giving chemotherapy for some high-grade tumours, where implants are inserted into the brain ( read more about carmustine implant treatment on Cancer Research UK) Dissection of a pupal brain at 30% pupal development. ( A) The anterior part of the pupa is submerged into 1× PBS. ( B) The thorax cuticle is pushed down and ( C) detached at the suture at the base of the head (along the dashed line) to make a small opening. ( D) The thoracic tissue and cuticle are pulled away horizontally from the head tissue (following the direction of the arrow). ( E) The developing head is visible at the bottom of the pupal cuticle. ( F) Extra pieces of pupal cuticle are removed. ( G) Then, the brain is gently scraped out. ( H) While detached from the pupa cuticle, extra head tissue can be removed from the brain (e.g., cornea, antennae, trachea (seen in a bright white colour)). ( I) The clean brain can be used for downstream analyses.
