我想使用 LaTeX 中的 TikZ 包绘制下图

Question

我正在尝试使用 LaTeX 中的 TikZ 包绘制这个边缘系统（大脑连接路线）

虚线显示学习过程，圆圈被视为神经元。

这是我目前拥有的代码：

\newcommand{\blocwithSum}[3]{
  \begin{scope}[shift={#1}]
    \begin{scope}[every node/.style={circle, draw, minimum size=2em}]
      \node[circle, draw] [blue](#2-c1){};
      \node[below left=1em of #2-c1][red](#2-c2){};
      \node[below left=1em of #2-c2][cyan](#2-c3){};
      \node[below left=1em of #2-c3][green](#2-cn){};
      \node[below right=2em and 1em of #2-c1][blue](#2-sum){\large $\Sigma$}; %to draw the sum
    \end{scope}
    \node[above left=1em and 0em of #2-c1](#2-tt){#2};%Amygdala
    \node[draw,blue,fit=(#2-c1) (#2-c2) (#2-c3) (#2-cn) (#2-tt) (#2-sum)](#2){};%to draw the box4
    \draw[->,red,thick] (#2-c1)-|(#2-sum); \draw[->,blue,thick] (#2-c2)--++(2em,0) --(#2-sum);
    \draw[->,green,thick] (#2-c3)--++(2em,0) --(#2-sum);
    \draw[->,cyan,thick] (#2-cn)-|(#2-sum);
  \end{scope}
}

\begin{tikzpicture}
  \bloc{(0,0)}{Thalamus}
  \bloc{(4cm,0)}{Sensory Cortex}
  \blocwithSum{(9cm,0)}{Orbitofrontal Cortex}
  \blocwithSum{(1cm,-5cm)}{Amygdala}
  \foreach \ii in{1,2,3,n} {
    \node[draw][red](E\ii) at (Thalamus-c\ii-|-5,0){$S_{\ii}$};
    \draw[->,blue,thick] (E\ii)-- (Thalamus-c\ii);
    \draw[->,red,thick] (Thalamus-c\ii) -- (Sensory Cortex-c\ii);
    \draw[->,green,thick] (Sensory Cortex-c\ii) -- (Orbitofrontal Cortex-c\ii);
    \draw[->,thick] (Orbitofrontal Cortex-c\ii) -- (Amygdala-c\ii);
  }
\end{tikzpicture}

这是一个概要解决方案，我留给你去完成它。
