Abstract

To give a concrete aspect of structure, topography and function of the different nervous systems of the Triatominae, we begin this study with a description of the senso-motor system. As the first part we choose the study of the brain and its nerves. The external form of the brain is conditioned by the anatomy and morphology of the head. The brain is situated in the posterior part of the head beneath and behind the ocelli. It is characterized by the reduction of its longitudinal extension and, by this, the connectives between Syncerebrum and Gnathocerebrum are extremely short, but large, and the third commissure is included in the mass of the mandibular segment of the Gnatocerebrum. The optical masses are of the typical form, also the optical commissure. The Central Corps is volumous and is directly linked with the majority of the centres of the Protocerebrum and Deutocerebrum. The Pedunculated Corps has only one glomerulus that looks like a pedunculated mushroom without any signal of the formation of a calyx, found in ants and other more evoluted insects. Beneath the Central Corps, the extremities of the pedunculus disintegrate and form a number of claviform annexes like in the primitive Machilidae. The Deutocerebrum is charact...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Social Learning

Social learning involves learning new behaviors through observation, imitation and modeling. Follow this feed to stay up to date on the latest research.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Single Cell Chromatin Profiling

Techniques like ATAC-seq and CUT&Tag have the potential to allow single cell profiling of chromatin accessibility, histones, and TFs. This will provide novel insight into cellular heterogeneity and cell states. Discover the latest research on single cell chromatin profiling here.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells.
