Movement-independent representation of reward-predicting cues in the medial part of the primate premotor cortex Open
Neural activity across the dorsal neocortex of rodents is dominated by orofacial and limb movements, irrespective of whether the movements are task-relevant or task-irrelevant. To examine the extent to which movements and a primitive cogni…

Summary Genetically encoded fluorescent sensors continue to be developed and improved. If they could be expressed across multiple cortical areas in non-human primates, it would be possible to measure a variety of spatiotemporal dynamics of…

Dynamics of motor direction representation in the primate premotor and primary motor cortices during sensorimotor learning Open
Summary Sensorimotor learning requires reorganization of neuronal activity in the premotor cortex (PM) and primary motor cortex (M1). However, how PM- and M1-specific reorganization occurs in primates remains unclear. We conducted calcium …

Optical deep-cortex exploration in behaving rhesus macaques Open
Two papers published in June 2021 used a two-photon microscope or one-photon miniature microscope to interrogate the motor cortex in behaving macaque monkeys. The imaging was performed over several months, and the direction of natural arm …

Tb <sup>3+</sup> -doped fluorescent glass for biology Open
Tb 3+ -doped glass emits GFP-like fluorescence and is versatile for various biological research purposes.
Structural dynamics and stability of corticocortical and thalamocortical axon terminals during motor learning Open
Synaptic plasticity is the cellular basis of learning and memory. When animals learn a novel motor skill, synaptic modifications are induced in the primary motor cortex (M1), and new postsynaptic dendritic spines relevant to motor memory a…

Arm movements induced by noninvasive optogenetic stimulation of the motor cortex in the common marmoset Open
Optogenetics is now a fundamental tool for investigating the relationship between neuronal activity and behavior. However, its application to the investigation of motor control systems in nonhuman primates is rather limited, because optoge…
