Feedback Circuits and Two-Port Blocks, Part 1: From Circuits to Blocks with Ports introduced the concept of the port and applied it to a simple example. In this third part, a feedback circuit example ...

Aversive experiences powerfully regulate memory formation, and memory strength is proportional to the intensity of these experiences. Inhibition of the neural circuits that convey aversive signals ...

What is hard about analyzing feedback circuits is the extraction from the circuit diagram of the simple block diagram found in active circuits and control textbooks. To start with a relatively easy ...
