Hi dear,
There is a Term called Negative Resistance.If the value of current in a circuit terminal decreases with increase in voltage then circuit has negative resistance property.The best Example is tunnel diode.
Now when you change the direction of current….without changing the Voltage Polarity , the resistance become of opposite Sign.

Keep learning
