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.

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. Nat Protoc 11 — Each 2D representation was created by reconstructing area MT and the lesion from histologic sections in D, dorsal de mount.

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.

Metrics details. The cell bodies of sensory neurons, which transmit information from the external environment to the spinal cord, can be found at all levels of the spinal column in paired structures called dorsal root ganglia DRG. Rodent DRG neurons have long been studied in the laboratory to improve understanding of sensory nerve development and function, and have been instrumental in determining mechanisms underlying pain and neurodegeneration in disorders of the peripheral nervous system. Here, we describe a simple, step-by-step protocol for the swift isolation of mouse DRG, which can be enzymatically dissociated to produce fully differentiated primary neuronal cultures, or processed for downstream analyses, such as immunohistochemistry or RNA profiling. After dissecting out the spinal column, from the base of the skull to the level of the femurs, it can be cut down the mid-line and the spinal cord and meninges removed, before extracting the DRG and detaching unwanted axons. This protocol allows the easy and rapid isolation of DRG with minimal practice and dissection experience.

Linear regression was also performed to determine the hand preshaping behavior against food lengths Prism version 8. Therefore, we hypothesized that an early-life lesion in MT will permanently perturb reaching-to-grasp behaviors and result in dysfunction of areas directly connected with MT. Brain 97 — Vis Neurosci 9 — A banana pellet was dropped in the spinning bowl and bounced around. This concept has also been observed clinically in subject BI, who, following a bilateral early-life injury to V1 has significant preservation of vision, including sensitivity to moving stimuli. Brain sections were imaged with an Axio Imager Z1 microscope Zeiss. Neuroscience 5 — J Neurosci 5 — This suggests that MT is required for prehension throughout life.

J Neurophysiol 52 — To ensure adequate compliance with the task, we first trained the animals to enter a removable transport box on the home cage, which was then taken into the behavior laboratory Fig. Therefore, the spatiotemporal sensitivities appeared unaffected by an early-life MT ablation. Correspondence should be addressed to James A. Experimental design and statistical analysis Behavioral data were collected from two nonlesioned control animals and two MT-lesioned animals. Because there is a strong correlation between the age when an injury is acquired and the preservation of abilities that neuroplasticity offers, we wanted to explore the effects an MT lesion would have on visuomotor behavior in a developing visual system. Early-life lesions in MT lead to widespread changes in cortical architecture An advantage of our early-life lesion model is that it allows us to perform longitudinal MR imaging following the lesion. V1 responses are altered following an early-life lesion in MT As there is a significant reciprocal monosynaptic connectivity between MT and V1, we wanted to observe whether an early-life lesion of MT had an impact on the response properties of neurons in the LPZ of the ipsilesional V1 in adulthood. Visuomotor behavior following a bilateral MT lesion in adulthood has been examined in the macaque Gattass et al.
