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.

Optical techniques for functional imaging in mice have a number of key advantages over other common imaging modalities such as magnetic resonance imaging, positron emission tomography or computed tomography, including high resolution, low cost and an extensive library of available contrast agents and reporter genes. A major challenge to such work is the limited penetration depth imposed by tissue turbidity. We describe a window chamber technique by which these limitations can be avoided.

Standard anatomical terms of location are used to unambiguously describe the anatomy of animals , including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front "anterior" , behind "posterior" and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates , some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle "proximal" or further from the middle "distal". International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. These allow parties that use anatomical terms, such as anatomists , veterinarians , and medical doctors , to have a standard set of terms to communicate clearly the position of a structure. Standard anatomical and zoological terms of location have been developed, usually based on Latin and Greek words, to enable all biological and medical scientists, veterinarians , doctors and anatomists to precisely delineate and communicate information about animal bodies and their organs, even though the meaning of some of the terms often is context-sensitive.

The implications of this current study extend our understanding of the central role area MT occupies in the early establishment of the dorsal stream and associated behaviors and the role as an anchor in the developing visual cortex.

A banana pellet was dropped in the spinning bowl and bounced around. Diffusion encoding gradients were applied in 30 directions, with a b value of , gradient duration of 5 ms, and separation of 18 ms.
