Systematics of the Enigmatic Neotropical Rodent Genus Microakodontomys (Cricetidae: Sigmodontinae): New Evidence Supporting Its Distinctiveness and Endangered Status

open access: yesZoologica Scripta, EarlyView.
ABSTRACT The diversification of Neotropical sigmodontine rodents represents one of the most remarkable evolutionary events among mammals, encompassing numerous endemic, rare, and endangered genera and species. One of the most emblematic examples is Microakodontomys transitorius Hershkovitz 1993, originally described from a single specimen based on ...

Two‐tone suppression between the ultrasounds above and within the hearing range in mice

open access: yesExperimental Physiology, EarlyView.
Abstract Hearing range differs among various species. Ultrasound, which is audible to microbats and dolphins, is inaudible to humans through air conduction. However, it can create an auditory sensation when the stimulation is transmitted through the temporal bone.

Calcium regulation of muscle spindle mechanosensory afferent function

open access: yesExperimental Physiology, EarlyView.
Abstract Extracellular calcium is crucial for the normal function of muscle spindle sensory afferents. They express multiple calcium buffering proteins. Extracellular calcium is essential for recycling of synaptic‐like vesicles (SLVs) in the terminals and for the stretch‐evoked inward calcium current of the receptor potential.

Kif1a and intact microtubules maintain synaptic‐vesicle populations at ribbon synapses in zebrafish hair cells

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Sensory hair cells of the inner ear and lateral‐line system exhibit strong synaptic‐vesicle enrichment at the presynapse, around specialized structures called ribbons. We find that hair cells in the zebrafish lateral‐line system rely on the kinesin motor protein Kif1a and microtubules to enrich synaptic vesicles at presynaptic ...

Paired corticospinal‐motoneuronal stimulation enhances ballistic motor learning and corticospinal plasticity in older adults

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The first part of this experimental study showed that late adulthood (adults aged 65–75 years) is associated with reduced motor performance and learning of simple vigorous finger movements. The second part of the study shows that ballistic motor learning can be improved in older adults when a practice session is preceded by a ...
