Non-human primate neuroimaging is a rapidly growing area of research that promises to transform and scale translational cross-species comparative neuroscience. Unfortunately, the technological methodological advances past two decades have outpaced accrual data, which particularly challenging given relatively few centers necessary facilities capabilities. The PRIMatE Data Exchange (PRIME-DE) addresses this challenge by aggregating independently acquired non-human magnetic resonance imaging...
The songbird brain is able to discriminate between the bird's own song and other conspecific songs. Determining where in own- selectivity emerges of great importance because experience-dependent mechanisms are necessarily involved regions sensitive self-generated vocalizations could mediate auditory feedback that necessary for learning maintenance. Using functional MRI, here we show this present at midbrain level. Surprisingly, was found be lateralized toward right side, a finding...
Abstract Despite advancements in video-based behaviour analysis and detection models for various species, existing methods are suboptimal to detect macaques complex laboratory environments. To address this gap, we present MacqD, a modified Mask R-CNN model incorporating SWIN transformer backbone enhanced attention-based feature extraction. MacqD robustly detects their home-cage under challenging scenarios, including occlusions, glass reflections, overexposure light. evaluate compare its...
Social influence on song acquisition was studied in 3 groups of young European starlings raised under different social conditions but with the same auditory experience adult song. Attentional focusing preferred partners appears most likely explanation for differences found relation to experience, sex, and categories. Thus, pair-isolated birds learned from each other not broadcast live songs, females did learn male tutors, sharing occurred more between socially associated peers. On contrary,...
Song perception in songbirds, just as music and speech humans, requires processing the spectral temporal structure found succession of song-syllables. Using functional magnetic resonance imaging synthetic songs that preserved exclusively either or natural song, we investigated how vocalizations are processed avian forebrain. We bilateral equal activation primary auditory region, field L. The more ventral regions L showed depressed responses to lacked structure. These included subarea L3,...
The song control system (SCS) of seasonal songbirds shows remarkable plasticity. Male starlings (Sturnus vulgaris) sing throughout the year, but in breeding season, when concentrations testosterone are elevated, is highly sexually motivated. main goal this study was to investigate structural changes regions involved auditory processing and socio-sexual behavior. Using vivo Diffusion Tensor Imaging (DTI), we measured nonbreeding seasons volume tissue characteristics several brain nine adult...
This work examined the mechanisms underlying auditory motion processing in cortex of awake monkeys using functional magnetic resonance imaging (fMRI). We tested to what extent analysis can be explained by linear combination static spatial mechanisms, spectrotemporal processes, and their interaction. found that posterior cortex, including A1 surrounding caudal belt parabelt, is involved analysis. Static processes were able fully explain motion-induced activation most parts A1, but not...
Abstract Objective methods for assessing the cumulative lifetime experience of non-human animals would be valuable. We develop hypothesis that biological age is a common currency integrates overall quality an animal's across range types exposure. Ageing result accumulation somatic damage, and its rate determined by balance between experiences cause damage mitigate or promote repair. Negative affective states are associated with via both direct causal indirect pathways. Based on these...
We have studied the localization of deformation in a 2D packing model. The samples consist regular packings equal parallel cylinders (drinking straws). local stress-strain characteristics, at contact between two straws, shows softening part, responsible for deformation. analyzed roughness band, i.e., width W localized zone versus its length L. Our results demonstrate self-affine character zone: find power law, W\ensuremath{\sim}${\mathit{L}}^{\mathrm{\ensuremath{\zeta}}}$ with...
Songbirds are an excellent model for investigating the perception of learned complex acoustic communication signals. Male European starlings (Sturnus vulgaris) sing throughout year distinct types song that bear either social or individual information. Although relative importance and information changes seasonally, evidence functional seasonal in neural response to these songs remains elusive. We thus decided use vivo magnetic resonance imaging (fMRI) examine auditory responses male were...
Recent efforts to chart human brain growth across the lifespan using large-scale MRI data have provided reference standards for development. However, similar models nonhuman primate (NHP) are lacking. The rhesus macaque, a widely used NHP in translational neuroscience due its similarities anatomy, phylogenetics, cognitive, and social behaviors humans, serves as an ideal model. This study aimed create normative charts structure macaque lifespan, enhancing our understanding of neurodevelopment...
Like human speech, birdsong is a learned behavior that supports species and individual recognition. Norepinephrine catecholamine suspected to play role in song learning. The goal of this study was investigate the norepinephrine bird's own selectivity, property thought be important for auditory feedback processes required learning maintenance.Using functional magnetic resonance imaging, we show injection DSP-4, specific noradrenergic toxin, unmasks selectivity dorsal part NCM, secondary...
