Butterfly Brain

Product Information

When butterflies go out for food, this same process is happening in their own brains in a specialized structure called the mushroom body. While humans boast an estimated 86 billion neurons, butterflies make good use of their 200,000. One species of butterfly, the Heliconius of Central and South America, is particularly good at navigating to their favorite food sources. Not only are they outstanding for their ability to remember visual markings in their environment, but their food preferences set them apart from all other closely related species. While most butterflies eat pollen at birth before maturing into a nectar-based diet, Heliconius butterflies continue to eat pollen throughout their lives. Daniel P.

How a Butterfly Brain Adapts During Metamorphosis

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.A glioblastoma is the most common high grade primary brain tumour in adults. It rarely occurs in children.

Butterfly Hug Method for Bilateral Stimulation The Butterfly Hug Method for Bilateral Stimulation

Growing wings is exactly what a caterpillar does when it metamorphoses into a butterfly. Imagine being as slow as a snail and then growing up to be able to fly like the birds ( well, not exactly). This transformation is one of the most remarkable feats of nature and has mesmerized poets and scientists alike.Speak to your care team if you'd like to know what the outlook is for you, as it varies from person to person.

The ventriclesare interconnected cavities located deep within the brain. They are filled with cerebrospinal fluid (CSF) which functions to protect the brain and spinal cord, provide nutrients and remove waste. There are the four ventricles housed within the brain: 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 Brains And Speciation | A Moment of Science

The subcortical structures are a group of diverse structures found deep within the brain. They include the diencephalon ( thalamus, epithalamus, subthalamus and hypothalamus), pituitary gland, limbic structures and the basal ganglia. Kahle, W., Frotscher, M., & Spitzer, G. (2003). Nervous system and sensory organs. New York: Thieme. The extrapyramidal motor system (rubrospinal, tectospinal, reticulospinal, and vestibulospinal tracts) originate from nuclei in the brainstem. By synapsing in the spinal cord this system controls other aspects of locomotor activity besides pure movement, such as coordination, reflexive movements and body posture. In our patient cohort, median EOR was 100 % in those patients having undergone surgical decompression. In this subgroup of six patients, the two patients with the longest survival presented with a KPS of 90, and maintained this KPS at the conclusion of XRT. The two patients to have received palliative measures only (comfort care) had presented with a KPS of 70. The final two patients in this subgroup presented with a KPS of 80 and 40, and both had a KPS of 50 at the conclusion of XRT. They survived 265 and 331 days respectively. Further review of this subgroup reveals no obvious relation between tumor volume and outcome. Our results, although limited, suggest that a balanced consideration of functional status as well as tumor burden should influence how aggressively surgical decompression should proceed. Kaplan–Meier plots of a overall survival of the entire cohort of patients with a butterfly glioblastoma and b the cohort of patients having undergone surgical biopsy compared to the cohort having undergone surgical decompression. All patients were included regardless of having received adjuvant therapy. Median survival for the biopsy group was 48 days compared to the surgically decompressed group of 265 days, p = 0.14 (log-rank)

Our results demonstrate heterogeneous outcomes. One factor is that different treatment regimens were used. Chemoradiation therapy was shown to provide a survival benefit for patients with newly diagnosed glioblastoma based on the publication by Stupp et al. in 2005 [ 15]. Hence, some patients in this study who were treated prior to 2005 received XRT alone. Four in the surgically decompressed group did not receive this regimen due to clinical factors such as anemia and poor functional status. During the transition to concurrent chemoradiation therapy, tamoxifen was prescribed as an alternative radiosensitizer for one patient.Six of the eleven patients who underwent a decompression procedure had 100 % of the enhancing volume of tumor removed. Two of these six patients received palliative (comfort care) measures only and the remaining four survived from 265 to 1,018 days. Spinal nerves are the major output of the spinal cord. They arise in pairs from corresponding spinal cord segments. There are 31 pairs of spinal nerves; 8 cervical, 12 thoracic, 5 lumbar, 5 sacral and 1 coccygeal Some of the best questions are from young scientists. Take for example this question about butterfly brains from a 5th grade student. Greer asked if a butterfly's brain is the same as when it was a caterpillar. Now that is a fantastic question.
