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.

We describe a three-dimensional 3D confocal imaging technique to characterize and enumerate rare, newly emerging hematopoietic cells located within the vasculature of whole-mount preparations of mouse embryos. However, the methodology is broadly applicable for examining the development and 3D architecture of other tissues. Previously, direct whole-mount imaging has been limited to external tissue layers owing to poor laser penetration of dense, opaque tissue. Our whole-embryo imaging method enables detailed quantitative and qualitative analysis of cells within the dorsal aorta of embryonic day E In this protocol we describe the whole-mount fixation and multimarker staining procedure, the tissue transparency treatment, microscopy and the analysis of resulting images.

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.

First, mapping of receptive fields in the MT complex was used to define the perimeter of the V1 scotoma. A , B , Voxel-based morphometry of FA maps. Brain Res Brain Res Protoc 11 — Trends Neurosci 15 — In this study, we observed no dramatic perturbations in the tuning properties of V1 neurons. Prog Neurobiol This suggests that MT is required for prehension throughout life. Inaki C. For each animal, six immunolabeled sections were randomly selected across the anterior—posterior axis across our areas of interest. The authors were unable to determine the impact that the adult-acquired bilateral MT loss would have on visuomotor behavior in moving objects. Visual behavior experiments commenced following a minimum of 12 months of recovery from the MT ablative surgery. To determine whether the food reward size influenced performance, an ANCOVA was performed to compare the error rate of large and small sizes across sessions Prism version 8. However, MT responses remained robust and largely unaffected following V1 lesions sustained in early life Yu et al.

Brain samples were cryosectioned in the coronal plane at 50 um, divided into five series, and stored free-floating in a cryoprotective solution as described previously Bourne and Rosa, Nat Protoc 11 — Cereb Cortex 17 — Quantification of interneuronal density was conducted as described previously Mundinano et al. 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. Moving object task: successful and failed reach-and-grasp attempts. Analysis of visual behavior performance Trials for the static object task were binned into three main categories; a successful trial was defined as a single coordinated motor action to retrieve the object. Although LM clearly had akinetopsia, she demonstrated an ability to reach and grasp static objects and moving objects up to speeds of 0. Teleologically, the early establishment of the dorsal stream network provides primates with the capacity to process vision for action, including accurate reaching-and-grasping behavior, which is integral to their survival. Vis Neurosci 31 — These two positions could favor either the left or right hand. Figure 6.
