AI 中文摘要
通过利用部分信息分解，我们分析了接收两股整合输入流的局部处理器中的信息传输。我们修订了先前基于部分信息分解分量提出的情境调制条件，并引入了信号整合存在性的条件。使用Ibroja方法，我们获得了信息论度量及部分信息分解分量的精确结果。我们考虑了一类一般的激活函数，以及一种特定的除法归一化传递函数。这些结果被应用于多种激活函数，包括加法、乘法、减法和除法形式，并附有图形说明，每种情况下都检验了调制与整合的条件。修订后的信息论条件也被应用于从模型第5b层锥体细胞的实际模拟中获得的噪声数据，该模拟处于由实验设计定义的三种不同状态，并以输入基底和顶端振幅的值为特征。我们提供了基底输入驱动顶端输入调制、顶端输入驱动基底输入调制以及顶端-基底信号整合的证据。
英文摘要
By making use of partial information decomposition, we analyse information transmission through a local processor which receives two streams of integrated inputs. We revise previously stated conditions for contextual modulation that are based on the components of partial information decomposition, and introduce a condition for the presence of signal integration. Exact results are obtained for information-theoretic measures and the components of partial information decomposition using the Ibroja method. A general class of activation functions is considered along with a particular divisive normalisation transfer function. These results are applied with several activation functions, of additive, multiplicative, subtractive and divisive forms, with graphical illustration, and the conditions for modulation and integration are tested in each case. The revised information-theoretic conditions are also applied to noisy data obtained from a realistic simulation of a model layer 5b pyramidal cell in three distinct regimes defined by experimental design and characterised by the values of the input basal and apical amplitudes. Evidence for driving basal input with modulating apical input, driving apical input with modulating basal input, and of apical-basal signal integration is presented.
