While motivation typically enhances memory, some studies show that, in certain contexts, motivation associated with rewards can impair memory. Goal states associated with motivation can impact attention, which in turn influences what information is encoded and later remembered. There is limited research on how different incentive contexts, which manipulate attentional orientation to memoranda, lead to either reward-motivated memory enhancements or impairments in item and relational memory.

They were synthesized and their crystal structures were studied by both X-ray and neutron diffraction. Si and Ga/Al atoms are ordered into alternating layers, which was rationalized with the "coloring problem" study via first-principles calculations.

In the CA1 region of hippocampal slices prepared from juvenile (12- to 18-day-old) rats, activation of group I metabotropic L-glutamate (mGlu) receptors by the specific agonist (RS)-3,5-dihydroxyphenylglycine (DHPG) induces a form of long-term depression (LTD) of excitatory synaptic transmission. 2.
