Nicotinic acetylcholine receptors (nAchRs) are widely distributed within the nervous system across most animal species. Besides their well-established roles in mammalian neuromuscular junctions, studies using invertebrate models have also proven fruitful revealing function of nAchRs central system.

We will highlight promising new avenues research that likely contribute better understanding cholinergic other organisms.

Amyotrophic lateral sclerosis (ALS) is characterised by the progressive degeneration of motor neurons that innervate muscle, resulting in gradual paralysis and culminating inability to breathe or swallow. This neuronal occurs a spatiotemporal manner from point onset central nervous system, suggesting there molecule spreads cell-to-cell. There strong evidence progression ALS pathology consequence protein misfolding aggregation. In line with this, hallmark deposition inclusion formation within surrounding glia proteins TAR DNA-binding 43, superoxide dismutase-1, fused sarcoma. Collectively, observed aggregation, conjunction spread symptoms, strongly suggests prion-like propagation aggregation ALS. this review, we discuss role relation homeostasis (proteostasis) mechanisms propagation. Furthermore, examine experimental models used investigate these processes, including vitro assays, cultured cells, invertebrate models, murine models. Finally, evaluate therapeutics may best prevent ALS, what lies on horizon for treating currently incurable disease.

The motions that make up animal behavior arise from the interplay between neural circuits and mechanical parts of body. Therefore, in order to comprehend operational mechanisms governing behavior, it is essential examine not only underlying network but also characteristics animal’s locomotor system fly larvae serves as an ideal model for pursuing this integrative approach. By virtue diverse investigation methods encompassing connectomics analysis quantification locomotion kinematics, research on larval has shed light behavior. These studies have elucidated roles interneurons coordinating muscle activities within segments, well responsible exploration. This review aims provide overview recent neuromechanics larvae. We briefly interspecific diversity explore latest advancements soft robots inspired by locomotion. using could establish a practical framework scrutinizing other species.

Visually guided decision-making requires integration of information from distributed brain areas, necessitating a brain-wide approach to examine its neural mechanisms. New tools in Drosophila melanogaster enable circuits spanning the be charted with single cell-type resolution. Here, we highlight recent advances uncovering computations and that transform integrate visual across make behavioral choices.
