The modern monotremes (platypus and echidnas) are characterized by development of their young in a leathery egg that is laid into a nest or abdominal pouch. At hatching, the young are externally immature, with forelimbs capable of digitopal...
The transcription factor, Lmx1b, promotes a neuronal glutamate phenotype and suppresses a GABA one in the embryonic trigeminal brainstem complex [0.03%]

Achieving an appropriate balance between inhibitory and excitatory neuronal fate is critical for development of effective synaptic transmission. However, the molecular mechanisms dictating such phenotypic outcomes are not well understood, e...
Effect of high velocity, large amplitude stimuli on the spread of depolarization in S1 "barrel" cortex [0.03%]
高强度大振幅刺激对S1 barrels皮层去极化传播的影响

We examined the effect of large, controlled whisker movements, delivered at a high speed, on the amplitude and spread of depolarization in the anesthetized mouse barrel cortex. The stimulus speed was varied between 1500 and 6000°/s and the...
Rhythmic arm swing enhances long latency facilitatory effect of transcranial magnetic stimulation on soleus motoneuron pool excitability [0.03%]
节律性摆臂增强经颅磁刺激对腓肠肌运动神经元池长效易化效应

Koichi Hiraoka et al.
The purpose of this study was to investigate whether rhythmic arm swing modulates the long latency effect of transcranial magnetic stimulation (TMS) on soleus motoneuron pool excitability. Ten healthy humans rhythmically swung the left arm ...
Vibrotactile thresholds at the sole of the foot: effect of vibration frequency and contact location [0.03%]
脚底的振动触觉阈值：振动频率和接触位置的影响

Studies of vibration perception in the glabrous skin of the human hand have identified four mechanoreceptor channels, with each channel showing characteristic variations in thresholds with variations in the frequency of vibration and the ar...
Laterality and sex differences in tactile detection and two-point thresholds modified by body surface area and body fat ratio [0.03%]
基于体表面积和体脂比率的触觉检测及两点阈值的性别与利手差异研究

Tactile detection and two-point discrimination tests are commonly used in neurological examinations. However, questions remain about the influence of both body and patient characteristics on test thresholds. The left side of the body has so...
Characteristics of synaptic connections between rodent primary somatosensory and motor cortices [0.03%]
啮齿类动物初级躯体感觉皮层和运动皮层之间的突触连接特征

Mary Rocco-Donovan et al.
The reciprocal connections between primary motor (M1) and primary somatosensory cortices (S1) are hypothesized to play a crucial role in the ability to update motor plans in response to changes in the sensory periphery. These interactions p...

The tactile and thermal sensitivity of diverse regions of the human body have been documented extensively, with one exception being the scalp. Additionally, sensory changes may accompany the hair loss from the scalp in androgen-related alop...
Recognition memory for vibrotactile rhythms: an fMRI study in blind and sighted individuals [0.03%]
盲人和视力正常个体的触觉振动节律识别记忆功能磁共振研究
