Topographic Axes of Wiring Space Converge to Genetic Topography in Shaping Human Cortical Layout.

Genetic information is involved in the gradual emergence of cortical areas since the neural tube begins to form, shaping the heterogeneous functions of neural circuits in the human brain. Informed by invasive tract-tracing measurements, the cortex exhibits marked interareal variation in connectivity profiles, revealing the heterogeneity across cortical areas. However, it remains unclear about the organizing principles possibly shared by genetics and cortical wiring to manifest the spatial heterogeneity across cortex.

Sea turtles face numerous threats, often stemming from human activities, resulting in high mortality rates. One of the primary risks they encounter is posed by fishing activities. In the South Adriatic Sea, the extensive trawling fleet often impacts sea turtles, and in recent years, a specific disorder, known as gas embolism (GE), and the associated disease known as decompression sickness (DCS), has emerged as a new threat.

While both concentration and timing of morphogen exposure are crucial, how cells interpret these graded inputs remains challenging to address. We employed an optogenetic system to acutely and reversibly modulate the nuclear concentration of the morphogen Dorsal (DL), homologue of NF-κB, which orchestrates dorso-ventral patterning in the embryo.

- - A new genus of leafhoppers called Dutrapona has been identified within the Gyponini tribe, including three new species from Central and South America.
- - The newly described species are Dutrapona tenuis from Costa Rica, Dutrapona reticulata from Ecuador, and Dutrapona zahniseri from Panama, with Dutrapona tenuis being the type species.
- - Dutrapona can be differentiated from other genera in the Gyponini tribe by its unique physical traits, such as specific shapes and positions of ocelli, distinctive features of the crown, and characteristics of the male reproductive structures.
Track-Weighted Dynamic Functional Connectivity Profiles and Topographic Organization of the Human Pulvinar.
Hum Brain Mapp
December 2024
Brain Mapping Lab, Department of Biomedical, Dental Sciences and Morphological and Functional Imaging, University of Messina, Messina, Italy.
The human pulvinar is considered a prototypical associative thalamic nucleus as it represents a key node in several cortico-subcortical networks. Through this extensive connectivity to widespread brain areas, it has been suggested that the pulvinar may play a central role in modulating cortical oscillatory dynamics of complex cognitive and executive functions. Additionally, derangements of pulvinar activity are involved in different neuropsychiatric conditions including Lewy-body disease, Alzheimer's disease, and schizophrenia.
