In order to display some electrophysiological properties of the motoneurons, a special program for a microcomputer has been designed. The images in the monitor resemble those of an oscilloscope screen. The microelectrode penetration in the cell membrane, magnitude of the resting potential, inhibition and facilitation phenomena and the time-course of a spike potential are shown. The sequences of program's sentences (detailed in the text) can be exhibited in the screen also. Related theoretical basis of neurophysiology and a discussion of the present work are included.

Characterization of cognitive decline in long-duration type 1 diabetes by cognitive, neuroimaging and pathological examinations.

Background: We aimed to characterize factors associated with the under-studied complication of cognitive decline in aging people with long-duration type 1 diabetes (T1D).
Methods: Joslin "Medalists" (n = 222; T1D ≥ 50 years) underwent cognitive testing. Medalists (n = 52) and age-matched non-diabetic controls (n = 20) underwent neuro- and retinal imaging.
Glia control experience-dependent plasticity in an olfactory critical period.

Sensory experience during developmental critical periods has lifelong consequences for circuit function and behavior, but the molecular and cellular mechanisms through which experience causes these changes are not well understood. The antennal lobe houses synapses between olfactory sensory neurons (OSNs) and downstream projection neurons (PNs) in stereotyped glomeruli. Many glomeruli exhibit structural plasticity in response to early-life odor exposure, indicating a general sensitivity of the fly olfactory circuitry to early sensory experience.

Herein, fluorescent calcium carbonate nanoclusters encapsulated with methotrexate (Mtx) and surface functionalized with chitosan (25 nm) (@Calmat) have been developed for the imaging and treatment of triple-negative breast cancer (TNBC). These biocompatible, pH-sensitive nanoparticles demonstrate significant potential for targeted therapy and diagnostic applications. The efficacy of nanoparticles (NPs) was evaluated in MDA-MB-231 TNBC cell lines.

Schizotypy is a multidimensional construct that is composed of positive, negative, and disorganized dimensions. Historically, disorganized schizotypy, which involves disruptions in thoughts, speech, behavior, and affect, has been relatively understudied and less clearly operationalized than the other dimensions. The present study employed experience sampling methodology to examine the associations of positive, negative, and disorganized schizotypy, as measured by the Multidimensional Schizotypy Scale, with daily life experiences.

Synergy between superconductivity and ferromagnetism may offer great opportunities in nondissipative spintronics and topological quantum computing. Yet at the microscopic level, the exchange splitting of the electronic states responsible for ferromagnetism is inherently incompatible with the spin-singlet nature of conventional superconducting Cooper pairs. Here, we exploit the recently discovered van der Waals ferromagnets as enabling platforms with marvelous controllability to unravel the myth between ferromagnetism and superconductivity.
