1) 一个voxel中神经元活动是一致的,它们的活动以全或无的方式进行。 2) 一次神经元活动引起的血氧回流量的变化可以得到一个全脑一致的函数,即hrf函数。 图2.1 理想的hrf函数 3) 当一次神经活动引起的血氧回流量上升还没有结束时,又发生了一次神经冲动,两次信号激发的血氧回流量会叠加在一起。它们的叠加是线性...

Convolution is a mathematical operation that combines two functions to describe the overlap between them. Convolution takes two functions and “slides” one of them over the other, multiplying the function values at each point where they overlap, and adding up the products to create a new function...
Weight functions apply weights to an input to get weighted inputs. Z = convwf(W,P)returns the convolution of a weight matrixWand an inputP. dim = convwf('size',S,R,FP)takes the layer dimensionS, input dimensionR, and function parameters, and returns the weight size. ...
A Finite Impulse Response (FIR) digital signal processing circuit uses a double-accumulator technique to drastically reduce the number of multiply-accumulate operations which are necessary per sample of input data. The amount of reduction is dependent upon the shape of the filter function to be conv...
