The specific role of the striatum, especially its dorsolateral DLS and dorsomedial DMS parts, in male copulatory behavior is still debated. In order to clarify their contribution to male sexual behavior, we specifically ablated the major striatal neuronal subpopulations, direct and indirect medium spiny neurons dMSNs and iMSNs in DMS or DLS, and dMSNs, iMSNs and cholinergic interneurons in nucleus accumbens NAc , The main results of this study can be summarized as follows: In DMS, dMSN ablation causes a reduction in the percent of mice that mount a receptive female, and a complex alteration in the parameters of the copulatory performance, that is largely opposite to the alterations induced by iMSN ablation. In DLS, dMSN ablation causes a widespread alteration in the copulatory behavior parameters, that tends to disappear at repetition of the test; iMSN ablation induces minor copulatory behavior alterations that are complementary to those observed after dMSN ablation. In NAc, dMSN ablation causes a marked reduction in the percent of mice that mount a receptive female and a disruption of copulatory behavior, while iMSN ablation induces minor copulatory behavior alterations that are opposite to those observed with dMSN ablation, and cholinergic neuron ablation induces a selective decrease in mount latency. Overall, present data point to a complex region and cell-specific contribution to copulatory behavior of the different neuronal subpopulations of both dorsal and ventral striatum, with a prominent role of the dMSNs of the different subregions. Abstract The specific role of the striatum, especially its dorsolateral DLS and dorsomedial DMS parts, in male copulatory behavior is still debated.

Dorsal root ganglion stimulation DRG-S has significantly improved the treatment of complex regional pain syndrome CRPS , and it has broad applicability across a wide range of other conditions. Through funding and organizational leadership by the American Society for Pain and Neuroscience ASPN , this best practices consensus document has been developed for the selection, implantation, and use of DRG stimulation for the treatment of chronic pain syndromes. This document is composed of a comprehensive narrative literature review that has been performed regarding the role of the DRG in chronic pain and the clinical evidence for DRG-S as a treatment for multiple pain etiologies. Best practice recommendations encompass safety management, implantation techniques, and mitigation of the potential complications reported in the literature.

Although immunostaining of histologic sections does give an idea of the underlying vasculature, one of the shortcomings of these methods includes lack of possibilities of studying the vessel branching patterns. The whole mount staining of various mouse tissues provides an opportunity to study the entire vasculature including whole vessel width, vascular morphogenesis, and valve formations. In this chapter we present simple techniques for staining whole mount mouse embryonic dorsal skins DS and adult mouse corneal tissues for visualization of lymphatic and blood vasculature for research purposes.

The precise size of the food reward was qualified during the video analysis of each trial with built-in tools in Tracker software. It should be noted that motion is encoded in multiple cortical areas and not just in MT Tolias et al. Therefore, the intrinsic ability of the brain to translate motion perception into a meaningful and precise goal-directed action relies on more than just sensitivity to motion coherence and further reinforces how integral MT is for object interaction and the integral role it plays in the establishment of the associated networks during development. Each animal undertook goal-orientated reach-and-grasp tasks to permit interrogation of visuomotor capabilities. Independent variable Description Speed 10, 20, 30, 40, 50, 60 RPM Direction Clockwise or anticlockwise Hand use Aperture blocked to allow for only the left or right hand for object retrieval. Previously determined values for optimal spatial frequency was 1. C , An example trial where the animal was late in executing its reach for the food reward and failed in the moving object reach-and-grasp trial, the magnitude of which was calculated based on the angle between hand touch of plate and object. These results suggest that subsets of PV interneurons are components of specific cortical networks and that perisomatic inhibition contributes to the generation of precise response properties. All procedures were approved by the Monash University Animal Ethics Committee, which also monitored the health and well-being of the animals throughout the experiments. For each animal, six immunolabeled sections were randomly selected across the anterior—posterior axis across our areas of interest. Author contributions: W. Monosynaptic connectivity of the MT area of the visual cortex and unilateral early-life ablative lesion approach. The length of the food reward in each trial was measured against the reference scale and plotted against the MGA for the trial using Prism software version 8.

Here, we examined whether an early-life lesion in MT of marmoset monkeys six female, two male altered the dorsal stream development and the behavioral precision of reaching-to-grasp sequences. Mundinano , 1 Dylan M. Curr Biol 25 — Although LM clearly had akinetopsia, she demonstrated an ability to reach and grasp static objects and moving objects up to speeds of 0. Eur J Neurosci 31 — J Neurophysiol 57 — E , Summary of the extent and retinotopic relationship of MT lesion in each lesioned lesion animal. J Neurosci 29 — This observed behavior could be because of the inability of the animal to accurately detect the speed of the moving stimulus akinetopsia , a deficit that was also observed in LM. The performance as expressed by error rate was determined by dividing the number of failed trials by the total number of trials within a given session.
