说明

Analysis Note

以下是与我们的琼脂糖相关的性质列表：
硫酸盐含量 - 用作纯度指标，因为硫酸盐是其中存在的主要离子基团。
凝胶强度 - 破裂凝胶所需施加的力。
胶凝点 - 琼脂糖水溶液在冷却时的胶凝温度。琼脂糖溶液在液体-凝胶转变的过程中会表现出滞后现象 - 也就是说，它们的凝胶点与它们的熔点温度不同。
电内渗（EEO）- 液体通过凝胶的一种运动。琼脂糖凝胶中的阴离子基团被固定在基质上不能移动，但可解离的抗衡阳离子可以向基质中的阴极迁移，从而产生EEO。由于生物聚合物的电泳运动通常是朝向阳极的，因此EEO会因为内部的对流而破坏分离。

Imaging the impact of cortical microcirculation on synaptic structure and sensory-evoked hemodynamic responses in vivo.

Shengxiang Zhang et al.

PLoS biology, 5(5), e119-e119 (2007-04-26)

In vivo two-photon microscopy was used to image in real time dendrites and their spines in a mouse photothrombotic stroke model that reduced somatosensory cortex blood flow in discrete regions of cortical functional maps. This approach allowed us to define

Hemodynamic responses evoked by neuronal stimulation via channelrhodopsin-2 can be independent of intracortical glutamatergic synaptic transmission.

Nadia A Scott et al.

PloS one, 7(1), e29859-e29859 (2012-01-19)

Maintenance of neuronal function depends on the delivery of oxygen and glucose through changes in blood flow that are linked to the level of ongoing neuronal and glial activity, yet the underlying mechanisms remain unclear. Using transgenic mice expressing the

Dendrite-Specific Amplification of Weak Synaptic Input during Network Activity In Vivo.

Leiron Ferrarese et al.

Cell reports, 24(13), 3455-3465 (2018-09-27)

Excitatory synaptic input reaches the soma of a cortical excitatory pyramidal neuron via anatomically segregated apical and basal dendrites. In vivo, dendritic inputs are integrated during depolarized network activity, but how network activity affects apical and basal inputs is not understood. Using
