Episodic sucrose intake during food restriction increases synaptic abundance of AMPA receptors in nucleus accumbens and augments intake of sucrose following restoration of ad libitum feeding

Highlights • Episodic sucrose intake during food restriction increases future sucrose intake. • Recovery from food restriction decreases sensitivity to amphetamine. • A history of food restriction with episodic sucrose intake increases pSer845-GluA1, GluA2, and GluA3 in the accumbens PSD.
