The multi-dimensional nature of vocal learning

How learning affects vocalizations is a key question in the study of animal communication and human language. Parallel efforts birds humans have taught us much about how vocal works on behavioural neurobiological level.

Wireless, battery-free, subdermally implantable platforms for transcranial and long-range optogenetics in freely moving animals

Proceedings of the National Academy of Sciences, Год журнала: 2021, Номер 118(30)

Опубликована: Июль 23, 2021

Wireless, battery-free, and fully subdermally implantable optogenetic tools are poised to transform neurobiological research in freely moving animals. Current-generation wireless devices sufficiently small, thin, light for subdermal implantation, offering some advantages over tethered methods naturalistic behavior. Yet current using power delivery require invasive stimulus delivery, penetrating the skull disrupting blood-brain barrier. This can cause tissue displacement, neuronal damage, scarring. Power constraints also sharply curtail operational arena size. Here, we implement highly miniaturized, capacitive storage on platform of implants. With approaches digitally manage optoelectronic components, enable two classes applications: transcranial activation millimeters into brain (validated motor cortex stimulation induce turning behaviors) optogenetics arenas more than 1 m2 methodology allows previously impossible behavioral experiments leveraging modern toolkit.

AAV1 is the optimal viral vector for optogenetic experiments in pigeons (Columba livia)

Communications Biology, Год журнала: 2021, Номер 4(1)

Опубликована: Янв. 22, 2021

Abstract Although optogenetics has revolutionized rodent neuroscience, it is still rarely used in other model organisms as the efficiencies of viral gene transfer differ between species and comprehensive transduction studies are rare. However, for comparative research, birds offer valuable they have excellent visual cognitive capabilities. Therefore, following study establishes pigeons on histological, physiological, behavioral levels. We show that AAV1 most efficient vector various brain regions leads to extensive anterograde retrograde ChR2 expression when combined with CAG promoter. Furthermore, transient optical stimulation expressing cells entopallium decreases pigeons’ contrast sensitivity during a grayscale discrimination task. This finding demonstrates causal evidence involvement perception well proof principle provides groundwork methods rely birds.

Transcranial Nongenetic Neuromodulation via Bioinspired Vesicle‐Enabled Precise NIR‐II Optical Stimulation

Advanced Materials, Год журнала: 2022, Номер 35(3)

Опубликована: Окт. 28, 2022

Regulating the activity of specific neurons is essentially important in neurocircuit dissection and neuropathy therapy. As a recently developed strategy, nanomaterial-enabled nongenetic neuromodulations that realize remote physical stimuli have made vast progress shown great clinical potential. However, minimal invasiveness high spatiotemporal resolution are still challenging for neuromodulation. Herein, second near-infrared (NIR-II)-light-induced transcranial neurostimulation via bioinspired nanovesicles reported. The rationally designed vesicles obtained from vesicle-membrane-confined enzymatic reactions. This study demonstrates vesicle-enabled NIR-II photothermal can elicit neuronal signaling dynamics with precise control thus evoke defined neural circuits nontransgenic mice. Moreover, vesicle-mediated optical stimulation regulate mouse motor behaviors by eliminating light-emitting implants. Furthermore, biological modulation integrated photoacoustic brain imaging, realizing navigational, efficient Such neuromodulation mediated shows potential optical-theranostics neurological diseases organisms.

Cross-stage neural pattern similarity in the hippocampus predicts false memory derived from post-event inaccurate information

Nature Communications, Год журнала: 2023, Номер 14(1)

Abstract The misinformation effect occurs when people’s memory of an event is altered by subsequent inaccurate information. No study has systematically tested theories about the dynamics human hippocampal representations during three stages misinformation-induced false memory. This replicates behavioral results effect, and investigates cross-stage pattern similarity in hippocampus cortex using functional magnetic resonance imaging. Results show item-specific between original-event post-event stages. During memory-test stage, original information are weakened for true memory, whereas compete with to create When occurs, this conflict resolved lateral prefrontal cortex. Individuals’ traces predict parietal predicts These findings support multiple-trace model, emphasize reconstructive nature

Birdsong Learning and Culture: Analogies with Human Spoken Language

Annual Review of Linguistics, Год журнала: 2020, Номер 7(1), С. 449 - 472

Опубликована: Ноя. 16, 2020

Unlike many species, song learning birds and humans have independently evolved the ability to communicate via learned vocalizations. Both birdsong spoken language are culturally transmitted across generations, within species-specific constraints that leave room for considerable variation. We review commonalities differences between vocal bird species humans, behavioral, developmental, neuroanatomical, physiological, genetic levels. propose cultural transmission of repertoires is a natural consequence evolution at least some universals, as well in transmission, due phenotypes, which shaped by constraints. suggest it balance these features social environment allows propagate. describe new opportunities exploring meaningful comparisons human culture.
